With modern Lithium ion batteries its because as their capacity decreases over time the BMS can’t always keep up and recover the 100% point unless you’re occasionally draining it all the way. This can result in someone charging their battery to say 97% and leaving it for hours to reach a 100% it will never reach. This is potentially unsafe as it heats up the battery.
You’re probably already familiar with this resource, but Battery University has some interesting and useful information about batteries and it’s accessible enough for the layperson.

Which is entirely correct. Time as we know it is an “inside” parameter of our universe, and therefor any causality only exists inside our universe, too. Because causality always contains a temporal element as in “Event A happened, which caused Event B later”. We cannot make any assumption of “before the big bang” and therefor no assumption of “what caused the big bang” either.
At least not in any way we could relate to.
the common myth about Daddy Longlegs being highly venomous
Quite a childrens tale, even back then. Two reasons for it: First, the “Daddy Longlegs” has no ability to bite us. Even extreme thin parts of the skin, e.g. the lips, are still way to thick for it to penetrate with its teeth. Second, even if it could inject its venom (which really exists!) it would need to inject about half a cup of it into a grown adult (IIRC about the amount, it could be a quarter cup or a whole cup or something, but still in the range of “thousands of total spider weights”).
I remember an episode of Mythbusters where they tested this, and I found a neat website that claims to have the result of that test. ( mythbusters.fandom.com/wiki/Daddy_Long_Legs_Myth ). The result was that they could bite humans and pierce the skin, but the bite was not especially problematic.
Searching for Mythbusters Daddy Long legs also brought up some YouTube suggestions from the episode, which was called Buried in Concrete. I haven’t watched any yet but maybe the scene is somewhere.
Yeah I didn’t get taught any of the stuff mentioned for me either.
One thing I did notice that wasn’t mentioned was the tongue map, that I was taught about in the 90’s - you know the one that said that your tongue has different areas for detecting different kinds of tastes - sweet at the front tip, sour at the back, that kind of thing. All bullshit.
I remember even testing that one out as a kid, observing that it obviously wasn’t true, and bringing up my experience to my teacher. “No” was basically the only response I got. How did a myth like that catch on when it was so easily testable by literally anybody?
“Planet X (Planet 9) exists and explains gravitational pull”
Weird conspiracy theories were not taught at my school.
Also:
In 2017, a photograph appeared to prove that Amelia Earhart survived her plane crash and was taken prisoner by the Japanese. However, it was later proven that the photo was taken two years before her disappearance, leaving the mystery unsolved.
Updated understanding emerged around 2010
The updated understanding emerged 7 years before the photo appeared?
Planet 9 a conspiracy theory? Who’s conspiring against whom there :|
Afaik it was a legit theory since we discovered planet 8 that way and then people tried to use the same method for further planets. Also beyond Mercury there was supposed to be Vulcanus and people reported sightings but nothing added up
Discovery of planet 8 (Wikipedia):
unexpected changes in the orbit of Uranus led Alexis Bouvard to hypothesise that its orbit was subject to gravitational perturbation by an unknown planet. After Bouvard’s death, the position of Neptune was mathematically predicted from his observations, independently, by John Couch Adams and Urbain Le Verrier. Neptune was subsequently directly observed with a telescope
And then Mr Einstein had a thing or two to say about those gravitational disturbances being actually relativity and most things clicked into place (but you’ll still have a discrepancy between the known spacetime curving and observed orbits because it’s hard to know what mass is exactly where in the Kuiper belt etc.). Or something. I’m probably wrong on the details but that’s the broad strokes as I remember them
We didn’t get planet 9 in school either fwiw but I think it was in magazines or encyclopedia at my grandparents’ place that I heard of it

Just put in 2010 and most of everything it said is incredibly obvious. Plus some of the dates of updated sources seem really incorrect. For example, one of them is it is a myth that most oxygen comes from trees, but I very distinctly remember my math teacher of all people saying in 2006 or 2007 that when he was in school he corrected people that it’s mostly from plankton. And even if I’m misremembering this, he definitely said something about it being from plankton in those years, but it says the updated sources are from 2020.
It says that it is a myth that the big bang theory explains where the universe came from but in 2020 we found out it doesn’t explain what came before. Like… No? That’s always been what it is. Sure, it’s always been a Christian talking point to sort of say that, but then why say 2020?
But I guess it’s hard to really gauge what should and shouldn’t be included. I remember my 5th grade teacher telling me that Robert E. Lee was an honorable man. I don’t really remember exactly what all she said and if she got deeper into Lost Cause rhetoric than that, but she definitely said Lee was a “good man.”

I think it’s a neat idea but probably needs more contributors and for people to be a bit more critical with things. For example, an obvious one, I don’t see it mention that Pluto is no longer classified as a planet. That would be a great thing to mention, especially if you talk about things we used to consider planets but don’t any longer. Ceres is another example of this. In 1801 it was discovered and considered a planet until sometime in the 1950s (it seems like it wasn’t an all-at-once shift) when it was considered an asteroid despite its planet like appearance. Now it is considered a dwarf planet like Pluto.

Cool but flawed website.
Earlier times dont include myths that are on later years.
There is no overlap in myths between 1990 and 1970-80 but there is with the myths of the 60s, so we stopped teaching it for 20 years and then went back to it?
“Sugar causes hyperactivity in children” is mentioned to have been corrected around 1995 but stops making the list from 1980 onward. I have heard it after 95 but not from school.
I wanna recommend it to others but i cant in this state.
Part of the reason Pluto’s classification hit so hard in the US is that it’s the only ‘planet’ ever discovered by an USian astronomer. That national pride made the 2006 decision sting more than elsewhere. Some of the top figures from the AAS even challenged the legitimacy of the decision afterwards.
Huh. I don’t think national pride that was a factor in my disappointment. I was more sad because 9 is a better number than 8, and Pluto is just a cute little guy.
I care that it is draconian nonsense. It wasn't created by planetary scientists, or by consulting any. It was primarily created by a highschool teacher in Temecula California. It is temporally incongruent. Saying it is not a planet then calling it a planet in the following name is an oxymoron, or rather just moronic. And it impedes real science and science communication depreciating the era and discoveries that have happened.
The real definition of worlds is by gravitational differentiation and the point at which a body is dominated by geology.
No object is ever defined by external factors. It is a fundamental elementary logic failure to attempt to do so. If you drive your car in a bicycle lane and clear out all the cyclists, what the &%$# object is defined. Absolutely nothing! You may define a condition here, not an object, not a noun! The fact that this definition even exists is an epic embarrassment that makes the entire field look like a bunch of dogmatic clowns.
Because those other bodies are worlds. In centuries to come, every one of these will be important and uniquely valued.
What kind of argument is "reality too hard to science." – Dogmatic clown level arguments. Anyone stating this should be purged from academia. This is the culture of the crisis academics talk about. This is the collapse. Fundamental contextual logic has failed. Planet is a verb, by the IAU definition, used incorrectly as a noun, in an oxymoron, with recursion. That is epic 16th century level nonsense. Nouns and verbs are what, 3rd grade level skills?

IMO, that site needs more cold war propaganda myths.

Truth: The biggest battles of the last few years of WWII were between Germany and the USSR, and the USSR won, pushing the German army back to Berlin.

Myth: Unions are communism, and therefore bad.
Truth: It is thanks to Unions that we work 8 hour days instead of 12 hour days, and that we have a 2 day weekend. They’re an essential part of balancing the power of the rich against the power of the workers.
–
Myth: Unions hold back the most skilled, so if you’re skilled or smart you shouldn’t be in a union.
Truth: The best actors in the world are members of SAG-AFTRA. They negotiate deals where they make tens of millions per movie. The union doesn’t hold them back. It just means that when the film studios try to screw over the less powerful actors and the union votes to strike, the rich and powerful actors need to do their part to help the less powerful actors out.

It took them a long time to get there. As corporate ISPs took over from the government and universities, the Internet got built around a few large pipes rather than several smaller ones. It’s cheaper to build and maintain, but more prone to failure.
Some of the redundancy from the old ARPANET is still around in the US. Everywhere else, it mostly got built as above. One ship laying an anchor somewhere they shouldn’t has brought entire countries offline.
[…] the Internet (it was a written with a capital I back then)
Back then, an internet (lower case “i”) was a small internal network of computers that communicated with each other.
The World Wide Web, being a massive collection of computers across the globe that are interconnected, quickly earned the title of “THE Internet” (upper-case “i”), to differentiate it from smaller isolated networks.
“World Wide Web” turned out to be a mouthful to say, so we replaced it with “the Internet” instead. Although most websites still start with “www” to represent their global reach.
Nowadays, we’ve stopped using the word “internet” to describe smaller networks, so the word mostly just refers to the global network. And as such, if doesn’t really matter if you capitalize it or not.
However, I was there when the web became accessible to the public and the nomenclature has stuck, so I always capitalize the Internet when referring to it.

Well, this is something that felt off indeed. But please explain. So http(s) is the world of http requests, but you can also have other services like ftp, ssh, bittorrent and what not. Is that what you mean? So the WWW is just the global interconnection of web pages strictly, over the Internet? Would this apply to any internet? /genuine
basically, yeah. internet is network of computers spanning all earth. intranet is smaller network of computers. intranet is often more private network under more centralized control of someone, with limited access from outside, that can be operated for example by some corporation or university, accessible only for employers or students (possibly using vpn to remotely connect to the network).
www. is the name of the service - http is a protocol it uses.
e-mail is the name of service - to access it, lot of people use http protocol if you use webmail, or imap or pop3 protocol if you use some dedicated client (like thunderbird, outlook, or others). smtp protocol is used to send the message to another mail server (you may have also been asked to configure it when manually configuring some dedicated e-mail client).
ftp, ssh, bittorrent,VOIP telephony using SIP protocol, IRC are other useful services. all these services can be run on network of any size, internet or intranet.
for example majority of modern doorbell systems are running on sip protocol and they are basically small VOIP phones running primarilly on a limited intranet in one specific building. but if that local network has access to the internet, they can have, due to nature of what they are, an option to forward that “call” to any other telephone number in the world in case no one picks it up at home.
small web-developers routinely run their own web-server of their own desktop, which may only be accessible locally, from that one computer or their small home network, to test the web pages they are developing. whether it is still world WIDE web is funny academical question then, because that web is not very wide in such case.
Back then, an internet (lower case “i”) was a small internal network of computers that communicated with each other.
That’s what I was told too, but I never once encountered anybody who used the small-i “internet” term. I heard “network”, or “intranet” or often topology-related things like “the token-ring network”. For a network of networks, I’d hear “WAN” or “external network” but never “internet”. Maybe that’s just me, but I suspect that small-i “internet” was never really a term that was widely used, if at all.

The story of how North and South America were settled by the first humans. What I was taught was that the Bering Sea was frozen at the end of the last ice age, and then glaciers opened up and people migrated southward.
The problem is that the timing is too tight and the migration would have to have happened too quickly. Many native groups have long seen this story as flawed, as well.
This was covered in the book “1491”, and at the time of publication, researchers weren’t quite sure what model to replace it with. Probably some of the migration was using boats along the west coast rather than going over land. That book is getting pretty old now, though, and I’m not sure if or where things have settled out.
Racial supremacist preferred narratives favour suppressing evidence that Polynesians could navigate larger Pacific before Europeans could navigate Atlantic. But simply artifacts predate the “land bridge theory timing”
Genetic evidence clearly shows native americans origins are from Siberian people. While there are evidence Polynesians made contact with them before europeans, native americans were already well established for tens of thousands of years before then.
I recently told my mother that I’m probably the most intelligent person she will ever meet while explaining why her conservative beliefs are dumb as shit and she defensively asked what my IQ is…
I was no contact for the past eight years or so and it was at a family reunion that we saw one another.
I don’t know my IQ, I’m actually a pretty slow learner, and I have horrible test anxiety. But as a polyglot physicist with a dash of perpetual autodidactic inclinations, I’m pretty well informed and I don’t know if intelligence can be measured, but I know it when I see it.
It’s funny that conservatives think quick wit and fast words equate to intelligence without ever stopping to think about the substance.
Objectively speaking, intelligence is considered to be the ability to reason.
Following that line, high intelligence would be the ability to reason well.
However, we humans do well because we specialize. It was discovered early on that we can’t do everything.
One could say it’s our individuality which drives us towards having different proficiencies and the entire chain of schooling would better serve to explore and encourage pursuing such specializations.
Where the means to cultivate proficiency are lacking, the end result will often be incomplete.
That shouldn’t mean there is a lack of intelligence, but that it hasn’t been developed to its potential.
I would say.. the base intelligence remains the same while expectations rise in concert with each own’s path of development.
Life is neither easy nor fair. And opportunities aren’t equal. So i often try to remind myself that perspective changes with experience and as such any standard we set ourselves and others to tend to be laced with personal bias.

The one that immediately springs to mind doesn’t exactly fit the criteria, because it wasn’t even true at the time that I was taught it in public school in Texas. But my history teacher taught me that no real historian called it the “American Civil War,” and that it was correctly called “The War of Northern Aggression.” And, of course, although the Confederacy did want to keep slavery legal, their actual central reason for seceding was “states rights.”
Like I said, both of those are simply lies. Only propagandists call it “The War of Northern Aggression”, and it was always explicitly about slavery.
The sad thing is that I believed and repeated these lies for years after that. Note that, like most people, I didn’t have access to the internet to easily check things myself. Since at the time I had zero interest in reading about history, it was difficult to correct my knowledge.
It has demonstrated, to me at least, the importance of keeping propaganda away from children. The more you lie to children, the harder it will be for them to become functioning adults.
The narrative of the Pacific theater still being an intractable or unbeatable long-term conflict in 1945 was hugely overstated, and also leant heavily on racist notions of the Japanese being “brainwashed”.
Also, most wars could be ended more quickly by committing war crimes, we don’t allow it as a justification when it’s done by the losing side. There was also the option of using them on purely military targets, instead of the middle of a major city, murdering a six-figure number of civilians.

The “brainwashed” thing is somewhat true, at least from the perspective of an outsider, not due to a racial thing, but there is a cultural aspect in addition to the tendency for all sides to be brainwashed by their own propaganda.
But the Japanese propaganda told their soldiers to fight to the death, because if the Americans captured you, it would be worse than death. So, from the outside, they did appear to be brainwashed in that regard. Of course, Americans had similar propaganda making Japanese seem as evil as possible, often in the most racist way, so you’d have to say that Americans were brainwashed, too.
Also, culturally, I think American culture emphasizes each person more, while Japanese emphasizes community more, which means things like kamikaze are easier to sell. And that sort of thing also appears like brainwashing to the outside.
I mean, kamikaze pilots did exist, so there had to be a certain level of what you’re calling “brainwashing”.
And unless it’s also a myth (completely possible), but weren’t there Japanese soldiers found on an island years after the war had ended who were convinced that it was still going on?
They had literally agreed to surrender before the first bomb dropped, their only condition being that the emperor remain, which the US agreed to anyway.
In our timeline, after two nuclear bombs were dropped, a coup almost happened that would have blocked the surrender of Japan. Would it have been different without the bombs?

I don’t recall specifically being taught that, but I do recall believing that was a fact at the time, so it is very likely that I was taught that in class.
I wouldn’t be surprised if there were a couple of slaves like that, but even so, it’s a misleading statement. I actually think that using the truth to lie is a worse sin than just outright lying, because it’s easier to mislead more people like that.
I had a college professor, Honors US History, teach us that the Civil War was about trade, an agrarian society against an industrial society.

The texas schooling system is horrendous.
Most texans are genuinely dumb as shit because of how they’ve been hamstrung by their “education.”
When I went to grade school, I think it really depended on the local school district. I was lucky enough to grow up in a nice area with well-funded schools, and I have relatively few complaints about the education I received. However, in doing school activities, I had the opportunity to see schools in poorer districts, and there was a distinct difference.
At the time, I didn’t think too much about the difference, except that I didn’t feel as safe in some schools.
But looking back… Now I know why parents always shop around for better school districts, because there are some places where it would have been far more difficult to get a decent education.
That’s my knowledge from many decades ago. Maybe it’s gotten worse since then.
Similarly, in the US Northeast, I learned about the civil rights movement as a solved problem, and that slavery was basically the only (and long gone) system of oppression we’d had. “Black and brown people have their equal rights now, carry on!”
They are similar, but Torpor is involuntary, hibernation is voluntary. Torpor is for short periods of time, hibernation is for long periods. Torpor drops the body temperature just a little, hibernation drops body temperature significantly. Torpor allows an animal to wake up and move around minimally (like to get food/eat) while hibernation does not.

A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.[2]
wickerpedia
Cells can’t use the energy from sugar directly. The mitochondrion turns the sugar into another molecule that other organelles can use for energy.
Adenosine triphosphate (ATP) is a nucleotide triphosphate[2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the “molecular unit of currency” for intracellular energy transfer.[3]

Well, they can, but it’s not very efficient. They produce 4 atp at the cost of 2 atp. The mitochondrion generates 34 atp from pyruvic acid at the cost of 2 atp.

Friendly neighborhood microbiologist here. You’re right except for one thing: most cells can use sugar directly through anaerobic respiration. Mitochondria facilitate aerobic respiration, which utilizes oxygen and is far more efficient, albeit a bit slower, and produces carbon dioxide as its end product.
Fun fact: ever wonder where your weight goes when you lose weight? CO2. You literally breathe most of it out.
I can get as nerdy as you want if anyone has any questions.
Edit: another cool one! Part of the process that regenerates ATP from ADP is ATP synthase. Look it up! It’s literally a little biological waterwheel that utilizes a chemical gradient, established by the mitochondria, to smoosh ADP (adenosine DIphosphate) and a phosphate back together into ATP (adenosine TRIphosphate).

This is why partially why fiber helps with bulking and pooping. Fiber is “fiber” because it’s made of things we can’t digest, but our gut microbes can. One of the byproducts of their utilizing it is SCFAs, short chain fatty acids. These confer various benefits like reduced inflammation and enhanced mucous production, which helps you drop a deuce.
Feeding your microbes also means you grow more of them, which makes your turds bigger and easier for your intestines to push along.
Yet another fun fact: ruminants like cows ferment otherwise indigestible plant matter in their guts, breaking it down and growing absolutely huge quantities of microbes in the process. Then they digest those microbes. That’s how they get enough protein. A cow is a mooing, shitting house of horrors if you’re a microbe.

Depending on the concentration, it would hurt as it’s a bit of an acid, plus ATP outside of the cell is one of the mechanisms that drives inflammation, but it won’t give you extra energy or anything.
ATP is used to transfer energy more than store it, more like a wire than a battery. The average adult has about 250g of ATP in their body (for my fellow Americans: about one rather chunky hamster) but it’s recycled about 200 times a day, so would require 50kg (6 watermelons or two average labradoodles) if it was used and discarded.
ATP has been around since the beginning of life or near enough, and evolution is a deranged, cat-piss-soaked hoarder that makes use of whatever is already lying around, so ATP also does several things beyond energy transfer. This also means where ATP is allowed and in what quantity is fairly controlled. To that end, there’s a class of enzyme called ectonucleotidases that’s found on the outside of cells. One of the things it does is keep the level of circulating ATP and things like it low, so whatever was injected would get chopped up pretty quick.
It just means it’s the system that turns food molecules and oxygen into energy for the cell. The cell itself doesn’t know how to do this which is quite spectacular when you think about it. So if the mitochondria died the cell would die.

There are human cells without mitochondria, and plenty of energy chains outside of mitochondrial action.
There are, in fact lots of them: your red blood cells, for example.
Mitochondria are more efficient at energy production, not the only source. Red cells use glycolysis.
You as a human organism would die pretty fast because you need that more efficient energy production but a lot of your cells would be fine until the effects of the system collapsing around them go into effect.

In each case, right up until the moment I received evidence to the contrary, all this misinformation, these supposed facts, felt true to me. I had believed them for decades and I had accepted them in part because they seemed to confirm all sorts of other ideas and opinions floating around in my mind. Plus they would have been great ways to illustrate complicated concepts, if not for the pesky fact that they were, in fact, not facts.
That’s one of the reasons why common misconceptions and false beliefs like these spread from conversation to conversation and survive from generation to generation and become anecdotal currency in our marketplace of ideas. They confirm our assumptions and validate our opinions and, thus, they raise few skeptical alarms. They make sense and they help us make sense of other things.

The rebuilding thing was a plan specific to WWII. They wanted to avoid the issues that the end of WWI brought to keep another war from happening a couple decades down the line.
The US also wanted an ally in the area who was into capitalism. Similar to how SK got a lot of support in building their infrastructure, but they went even farther into capitalism. Both countries are really depressed now.

I guess so, but similar to how a lot of taste is actually perceived via smell? I suppose linear and angular acceleration could be two separate senses which encompass the sense of balance.
Eh, it’s not really similar though. Yes, a lot of what we think of as “taste” is actually perceived via smell. But separately from that, there is actually a phsyiological sensation of taste that is unrelated to smell, i.e. the five basic tastes: sweet, sour, salty, bitter, and savoury.
Whereas there isn’t really any meaningful distinction between the sense of acceleration and balance. They’re exactly the same sensation, and the mind only knows which one you’re actually experiencing by cross-referencing what your other senses tell you. If you’re in a situation where these other senses are unavailable, people generally can’t distinguish whether they’re accelerating or off balance.
This has led to a number of plane crashes in history, in situations where pilots are in dense cloud cover and can’t see the horizon. During stressful situations, if they forget to look at the artificial horizon display, they think the plane is pitching up, and therefore try to pitch down to correct, when in fact the plane is accelerating (due to already being pitched down), resulting in a crash.

In theory we can break down the sense of sight into subcomponents, too. It’s only the visual cortex that processes those raw inputs into a coherent single perception. We have two eyes but generally only perceive one image, even if the stereoscopic vision gives us a good estimate of distance, and one eye being closed or obscured or blinded fails pretty gracefully into still perceiving a single image.
We have better low light sensitivity in our color-blind rods but only have color perception from our cones, and only in the center of our visual field, but we don’t actually perceive the loss of color in those situations.
So yeah, someone putting a warm hand on my back might technically set off different nerve sensors for both temperature and touch, but we generally perceive it as a unified “touch” perception.
Similarly, manipulating vision and sound might very well throw off one’s proprioception, because it’s all integrated in how it’s perceived.

It doesn’t help that planet has such an incredibly vague definition. Earth is a planet but so is Jupiter but other than being spherical they don’t have anything in common. In terms of similarities, Pluto is much more like Earth then Jupiter is like Earth, at least Pluto has a solid surface.
It’s not vague at all. It’s a classification that needs to meet three criteria. The lack of this classification is why it was taught that pluto was a planet, but once these things were formalized in 2006 it became clear that pluto no longer met the criteria.
Yes and I know that Pluto fails the final test, although it’s a bit difficult to really to say in what context that matters, because it’s in the Kiper belt which is incredibly diffuse anyway.

So you should hit a variety of teaching styles not because different students react better to some of them but because it triggers their attention and motivation mechanisms. We also get taught that switching too much tires the students out, so we should pick some 3 types of activities and rotate between them, tending to reduce the traditional lecture style.

I teach at university level.

He was trying to prove that electricity was dangerous. Even at the time though a lot of people pointed out that the voltage used was not the voltage used in mains electrics so it was basically a pointless thing to do and people quite upset about the elephant. He did receive a fair amount of bad press for it.
Edison’s electricity was the same 110volts. But it it was 110v from generators to peoples homes and thus suffered greatly from resistance losses.
Telsa’s AC however used high voltages for distribution and step down to 110v at the final destination, so the resistance losses were much lower. Edison’s propaganda conveniently glosses over that fact.

Oh, it wasn’t just elephants. He did it with dogs, monkeys, etc. This wasn’t a one-time thing, he provided this “demonstration” on a variety of occasions.
All because he wanted the world to adopt his standard for electrical transmission, direct current (DC) instead of Nikola Tesla’s alternating current (AC).
Tesla was a brilliant engineer and inventor. He knew EXACTLY what he was doing (though later he did get a little nutty). Edison just yelled at engineers he hired to do work for him.
I am so sad that Tesla’s name has been ruined. He was wildly intelligent and though he was a prominent figure in his prime, he died broke. It’s not bad enough that he went out like that, now we have a fucking clown pissing on his grave by using his name to sell his bullshit nazimobiles.

Can it even be said that it was perfected when later we switched from carbon filament to tungsten, and from there to halogen-surrounded tungsten.
And on the other side, Edison’s lamp wasn’t even the first one to be mass produced and commercially sold.
There’s a certain style of education that really wants to draw a hard line between “before the thing” and “after the thing”, and credit its invention to a single guy. But really the line is quite wide and fuzzy.

Well some shots do work like that. But you usually don’t get symptoms unless you are immunocompromised and it’s a live (but weakened) version of the virus.
They were just a little wrong, “Flu shots give you a flu”.
There are 2 types of these shots essentially:
the pathogen is put into some other thing that creates stuff that fights against said pathogen. That stuff is then extracted and given in the shot.
the pathogen itself is processed and given to you. This causes your body to make stuff that fights against the pathogens. Your body then vaguely remembers how the pathogen felt and hence, increases the reaction your body does to any attack from a similar pathogen that comes the next time. This is the one corresponding to the above quote.
Of course, if your immune system is weak, the processed pathogen can be enough to give you quite a bit of a problem.
I know there are different types of vaccines, but really, experience should be enough to prove this assumption wrong many times over. I guess people just don’t get their flu shots…

I had this really awesome kind of angry and nihilistic history teacher in H.S. who offered an elective course that studied the repeated patterns through history leading up to genocide. It covered Armenia, Rwanda, and the Holocaust.
I don’t know if it was just the fact that we looked at the repeated overlaps between human behavior vs just memorizing historical events, but if more people took a course like Crimes against Humanity maybe they would learn to spot those clear patterns of human behavior that somehow happen over and over again without anyone noticing.
push back the second a nazi takes an inch as they will take more if you play the nice and tolerate. Not everyone is well intentioned.
Yep, the Holocaust didn’t happen overnight. It always starts as a slow slide into genocide, but once it picks up steam it turns into an avalanche. It drives me nuts that people keep pretending we should be entertaining any of this as just normal politics. The reaching across the aisle bullshit was insane a year ago (and really 10 years ago), but at this point it is literally enabling this shit to happen. You’re a collaborator.

I always understood it as your immune system gets weaker from being in the cold and makes it easier for viruses and such to propogate in your body. We’re constantly fighting off minor infections and disease, and thankfully our immune systems are pretty strong…cold does not help it.

I thought the opposite. That when you’re cold, and your body releases Norepinephrine, that it re-enforces your immune system.

Before AlexNet, SVMs were the best algorithms around. LeNet was the only comparable success case for NNs back then, and it was largely seen as exclusively limited to MNIST digits because deep networks were too hard to train. People used HOG+SVM, SIFT, SURF, ORB, older Haar / Viola-Jones features, template matching, random forests, Hough Transforms, sliding windows, deformable parts models… so many techniques that were made obsolete once the first deep networks became viable.
The problem is your schooling was correct at the time, but the march of research progress eventually saw 1) the creation of large, million-scale supervised datasets (ImageNet) and 2) larger / faster GPUs with more on-card memory.
It was fact back in ~2010 that SVMs were superior to NNs in nearly every aspect.

HOG and Hough transforms bring me back. honestly glad that I don’t have to mess with them anymore though.
I always found SVMs a little shady because you had to pick a kernel. we spent time talking about the different kernels you could pick but they were all pretty small and/or contrived. I guess with NNs you pick the architecture/activation functions but there didn’t seem to be an analogue in SVM land for “stack more layers and fatten the embeddings.” though I was only an undergrad.
do you really think NNs won purely because of large datasets and GPU acceleration? I feel like those could have applied to SVMs too. I thought the real win was solving vanishing gradients with ReLU and expanding the number of layers, rather than throwing everything into a 3 or 5-layer MLP, preventing overfitting, making the gradient landscape less prone to local maxima and enabling hierarchical feature extraction to be learned organically.

No, you are correct. Hinton began researching ReLUs in 2010 and his students Alex Krizhevsky and Ilya Sutskever used it to train a much deeper network (AlexNet) to win the 2012 ILSVRC. The reason AlexNet was so groundbreaking was because it brought all of the gradient optimization improvements (SGD with momentum as popularized by Schmidhuber, and dropout), better activation functions (ReLU), a deeper network (8 layers), supervised training on very large datasets (necessary to learn good general-purpose convolutional kernels), and GPU acceleration into a single approach.
NNs, and specifically CNNs, won out because they were able to create more expressive and superior image feature representations over the hand-crafted features of competing algorithms. The proof was in the vastly better performance, it was a major jump when the performance on the ILSVRC was becoming saturated. Nobody was making nearly +10% improvements on that challenge back then, it blew everybody out of the water and made NNs and deep learning impossible to ignore.
Edit: to accentuate the point about datasets and GPUs, the original AlexNet developers really struggled to train their model on the GPUs available at the time. The model was too big and they had to split it across two GPUs to make it work. They were some of the first researchers to train large CNNs with GPUs. Without large datasets like the ILSVRC they would not have been able to train good deep hierarchical convolutions, and without better GPUs they wouldn’t have been able to make AlexNet sufficiently large or deep. Training AlexNet on CPU only for ILSVRC was out of the question, it would have taken months of full-tilt, nonstop compute for a single training run. It was more than these two things, as detailed above, but removing those two barriers really allowed CNNs and deep learning to take off. Much of the underlying NN and optimization theory had been around for decades.

It’s not just about slavery. There was also state’s rights (to slavery), and the economic disparity (turns out free men work harder than slaves?!), and a clash of religious ideals (people that interpret the Bible as pro-slavery vs people that believe benevolence requires abolition). There were even one or two spots where water usage rights and federal funding were in controversy.
Well, I let you be the judge. Here’s a list of outdated facts that were commonly taught before the year 2000 but have since been updated, courtesy of ChatGPT:
Science / Space
Pluto is a planet.
Back then, Pluto was still the 9th planet. In 2006, the International Astronomical Union reclassified it as a “dwarf planet.”
The universe’s expansion was slowing down.
Many textbooks still suggested the universe might eventually collapse in a “Big Crunch.” In 1998, evidence of accelerating expansion was found, but it hadn’t fully filtered into school curricula by 2000.
Dinosaurs were cold-blooded and scaly.
In 2000, the “feathered dinosaur” revolution was just starting. Today, we know many theropods (including raptors) had feathers and were likely warm-blooded.
The continents “drift” slowly but are mostly stable now.
Continental drift was taught, but the understanding of plate tectonics was less developed in school-level detail. We now know tectonic activity reshapes Earth far more dynamically than was often taught.
Biology / Medicine
The human genome was incomplete.
In 2000, the Human Genome Project had just released its first draft. Many textbooks underestimated how complex genetics really is — for example, they suggested humans had ~100,000 genes, but it’s actually about 20,000.
Ulcers are caused by stress and spicy food.
That was the classic teaching. By the 1990s, scientists had already shown that ulcers are often caused by H. pylori bacteria, but the update wasn’t in most classrooms yet.
“Junk DNA” does nothing.
The idea that noncoding DNA was useless filler was common. Now we know much of it plays regulatory or structural roles.
History / Social Studies
The internet is a fad.
You may have heard skepticism about the internet being overhyped. Few predicted how deeply it would transform society in just two decades.
Christopher Columbus “discovered America.”
By 2000, it was still widely taught that Columbus “discovered” the New World, though evidence of Norse settlements (like at L’Anse aux Meadows) was already known — just not widely emphasized. Now, school curricula are far more likely to teach about Indigenous civilizations and earlier arrivals.
The Great Wall of China is the only man-made object visible from space.
This “factoid” was common in classrooms, but it’s false. The wall is not easily visible from orbit without aid, while cities, roads, and airports often are.
In an atom, the electrons orbit around the nucleus in the same manner as the planets orbit around the sun.
That’s been debunked for many many decades but middle scool still teaches this model. At least I wasn’t told back then how misleading and wrong that is, only in high school right before graduating the physics teacher emphasized this misconception. I remember how mad she was about it lol. I have no clue how its taught elsewhere.
The Bhor’s model is at least a useful simplification of the atomic structure. What needs taught is that everything you learn before college and intensive narrow topical courses is simplified to the point of being incorrect with the hope that you get enough of an intrinsic understanding of the concept that the less simplified explanation you get next will make sense. I say this because it will still be simplified to the point of being wrong, but will be a step closer to the truth. This is the essence of education.
Elementary/middle school: ice is water that has frozen solid
HS: ice is water that has lost enough energy that the molecules form a crystalline lattice.
College: there are actually 19 or 20 kinds of water ice that have been verified, but as many as 74,963 might exist.
Post-collegiate: There may be 74,963 kinds of ice, but I know one ICE we should definitely eliminate from this world.

I like it, though there wasn’t a single one of the false facts that I was taught in schools.
“Dinosaurs shed their skin all at once like snakes”
“Girls are naturally not as good at math as boys”
I don’t mean to be rude, but If this was taught in your school, everyone around you is probably a moron.
Yeah I think that the “you have to discharge your batteries entirely before charging them” would be a better fit, even though it wasn’t false at the time, but the technology changed
You still occasionally should, let it go all the way to dead, but for calibration reasons instead of safety reasons
That was the original reason. Ni-cad batteries develop a “memory” if they aren’t fully discharged loose capacity.
With modern Lithium ion batteries its because as their capacity decreases over time the BMS can’t always keep up and recover the 100% point unless you’re occasionally draining it all the way. This can result in someone charging their battery to say 97% and leaving it for hours to reach a 100% it will never reach. This is potentially unsafe as it heats up the battery.
Edit: Autocorrupt beansed up my comment
You’re probably already familiar with this resource, but Battery University has some interesting and useful information about batteries and it’s accessible enough for the layperson.
Where did you go to school? I’ve never heard of either of those before.
Those false facts were on the site. I was never taught that.
Besides every girl in my school were better than any boy at mathematics.
Ah sorry, I totally misread that lol!
I think a lot of those are highly dependent on where a person went to school and who their teacher was, because some of them are pretty far out there.
Yeah, the concept is nice, but it tells me that the Big Bang doesn’t explain what happened before it (the leading hypothesis is that the Big Bang started time, so there is no “before”) and sources a Wikipedia article on spiders. Then, it cites the common myth about Daddy Longlegs being highly venomous, says that that wasn’t dispelled until 2020, and then cites a fucking BuzzFeed listicle.
Buzzfeed out here doing the real work
The fucking MythBusters did an episode on that like 20 years ago.
Which is entirely correct. Time as we know it is an “inside” parameter of our universe, and therefor any causality only exists inside our universe, too. Because causality always contains a temporal element as in “Event A happened, which caused Event B later”. We cannot make any assumption of “before the big bang” and therefor no assumption of “what caused the big bang” either.
At least not in any way we could relate to.
Quite a childrens tale, even back then. Two reasons for it: First, the “Daddy Longlegs” has no ability to bite us. Even extreme thin parts of the skin, e.g. the lips, are still way to thick for it to penetrate with its teeth. Second, even if it could inject its venom (which really exists!) it would need to inject about half a cup of it into a grown adult (IIRC about the amount, it could be a quarter cup or a whole cup or something, but still in the range of “thousands of total spider weights”).
I remember an episode of Mythbusters where they tested this, and I found a neat website that claims to have the result of that test. ( mythbusters.fandom.com/wiki/Daddy_Long_Legs_Myth ). The result was that they could bite humans and pierce the skin, but the bite was not especially problematic.
Searching for Mythbusters Daddy Long legs also brought up some YouTube suggestions from the episode, which was called Buried in Concrete. I haven’t watched any yet but maybe the scene is somewhere.
Yeah I didn’t get taught any of the stuff mentioned for me either.
One thing I did notice that wasn’t mentioned was the tongue map, that I was taught about in the 90’s - you know the one that said that your tongue has different areas for detecting different kinds of tastes - sweet at the front tip, sour at the back, that kind of thing. All bullshit.
I remember even testing that one out as a kid, observing that it obviously wasn’t true, and bringing up my experience to my teacher. “No” was basically the only response I got. How did a myth like that catch on when it was so easily testable by literally anybody?
Ageism, it is always implied that adults are the ones right - because what adult would accept a child to disprove their logic?
It’s also one of those myths which people forget after a year; and even if its encountered again, it is treated as insignificant.
the landing page mentions “your tongue has taste zones”. though on the other hand brontosauruses are real again
“Planet X (Planet 9) exists and explains gravitational pull”
Weird conspiracy theories were not taught at my school.
Also:
The updated understanding emerged 7 years before the photo appeared?
This is why websites need downvotes.
Planet 9 a conspiracy theory? Who’s conspiring against whom there :|
Afaik it was a legit theory since we discovered planet 8 that way and then people tried to use the same method for further planets. Also beyond Mercury there was supposed to be Vulcanus and people reported sightings but nothing added up
Discovery of planet 8 (Wikipedia):
And then Mr Einstein had a thing or two to say about those gravitational disturbances being actually relativity and most things clicked into place (but you’ll still have a discrepancy between the known spacetime curving and observed orbits because it’s hard to know what mass is exactly where in the Kuiper belt etc.). Or something. I’m probably wrong on the details but that’s the broad strokes as I remember them
We didn’t get planet 9 in school either fwiw but I think it was in magazines or encyclopedia at my grandparents’ place that I heard of it
Just put in 2010 and most of everything it said is incredibly obvious. Plus some of the dates of updated sources seem really incorrect. For example, one of them is it is a myth that most oxygen comes from trees, but I very distinctly remember my math teacher of all people saying in 2006 or 2007 that when he was in school he corrected people that it’s mostly from plankton. And even if I’m misremembering this, he definitely said something about it being from plankton in those years, but it says the updated sources are from 2020.
It says that it is a myth that the big bang theory explains where the universe came from but in 2020 we found out it doesn’t explain what came before. Like… No? That’s always been what it is. Sure, it’s always been a Christian talking point to sort of say that, but then why say 2020?
But I guess it’s hard to really gauge what should and shouldn’t be included. I remember my 5th grade teacher telling me that Robert E. Lee was an honorable man. I don’t really remember exactly what all she said and if she got deeper into Lost Cause rhetoric than that, but she definitely said Lee was a “good man.”
That isn’t a response to the initial statement at all, which is very much an opinion or prediction rather than any claim to be a fact. I’m suddenly feeling pretty sceptical about this website.
I think it’s a neat idea but probably needs more contributors and for people to be a bit more critical with things. For example, an obvious one, I don’t see it mention that Pluto is no longer classified as a planet. That would be a great thing to mention, especially if you talk about things we used to consider planets but don’t any longer. Ceres is another example of this. In 1801 it was discovered and considered a planet until sometime in the 1950s (it seems like it wasn’t an all-at-once shift) when it was considered an asteroid despite its planet like appearance. Now it is considered a dwarf planet like Pluto.
Cool but flawed website.
Earlier times dont include myths that are on later years.
There is no overlap in myths between 1990 and 1970-80 but there is with the myths of the 60s, so we stopped teaching it for 20 years and then went back to it?
“Sugar causes hyperactivity in children” is mentioned to have been corrected around 1995 but stops making the list from 1980 onward. I have heard it after 95 but not from school.
I wanna recommend it to others but i cant in this state.
Both 1960 and 2020 are showing the same 6 facts, and the facts shown were debunked years before 2020
Why would they just lie about Pluto like that?
#Pluto4Lyf
Part of the reason Pluto’s classification hit so hard in the US is that it’s the only ‘planet’ ever discovered by an USian astronomer. That national pride made the 2006 decision sting more than elsewhere. Some of the top figures from the AAS even challenged the legitimacy of the decision afterwards.
US pride, again.
Huh. I don’t think national pride that was a factor in my disappointment. I was more sad because 9 is a better number than 8, and Pluto is just a cute little guy.
I care that it is draconian nonsense. It wasn't created by planetary scientists, or by consulting any. It was primarily created by a highschool teacher in Temecula California. It is temporally incongruent. Saying it is not a planet then calling it a planet in the following name is an oxymoron, or rather just moronic. And it impedes real science and science communication depreciating the era and discoveries that have happened.
The real definition of worlds is by gravitational differentiation and the point at which a body is dominated by geology.
No object is ever defined by external factors. It is a fundamental elementary logic failure to attempt to do so. If you drive your car in a bicycle lane and clear out all the cyclists, what the &%$# object is defined. Absolutely nothing! You may define a condition here, not an object, not a noun! The fact that this definition even exists is an epic embarrassment that makes the entire field look like a bunch of dogmatic clowns.
That definition exists because if you want to include Pluto and be consistent you have to include dozens of other bodies.
Because those other bodies are worlds. In centuries to come, every one of these will be important and uniquely valued.
What kind of argument is "reality too hard to science." – Dogmatic clown level arguments. Anyone stating this should be purged from academia. This is the culture of the crisis academics talk about. This is the collapse. Fundamental contextual logic has failed. Planet is a verb, by the IAU definition, used incorrectly as a noun, in an oxymoron, with recursion. That is epic 16th century level nonsense. Nouns and verbs are what, 3rd grade level skills?
So it was basically laziness on the part of the international astronomical community.
It’s in fact a teenager planet and it doesn’t clean his room. Once it does it will be bumped back to planet.
We’re doing this for his own good.

IMO, that site needs more cold war propaganda myths.
For example:
Myth: The US won WWII
Truth: The biggest battles of the last few years of WWII were between Germany and the USSR, and the USSR won, pushing the German army back to Berlin.
–
Myth: Unions are communism, and therefore bad.
Truth: It is thanks to Unions that we work 8 hour days instead of 12 hour days, and that we have a 2 day weekend. They’re an essential part of balancing the power of the rich against the power of the workers.
–
Myth: Unions hold back the most skilled, so if you’re skilled or smart you shouldn’t be in a union.
Truth: The best actors in the world are members of SAG-AFTRA. They negotiate deals where they make tens of millions per movie. The union doesn’t hold them back. It just means that when the film studios try to screw over the less powerful actors and the union votes to strike, the rich and powerful actors need to do their part to help the less powerful actors out.
Was gonna say, I’ve seen this reposted for so many years I figured some one would have made it by now, o/w I was gonna. Thank you not-yet-dead Internet
The very architecture of the Internet (it was a written with a capital I back then) made it impossible to take over, and traffic would naturally route around any damaged links or nodes.
Google and CloudFlare have since proven that sonsabitches with enough money can subvert it completely, and it only takes a few dudes dragging an anchor from a boat to disconnect entire countries for weeks and months.
It took them a long time to get there. As corporate ISPs took over from the government and universities, the Internet got built around a few large pipes rather than several smaller ones. It’s cheaper to build and maintain, but more prone to failure.
Some of the redundancy from the old ARPANET is still around in the US. Everywhere else, it mostly got built as above. One ship laying an anchor somewhere they shouldn’t has brought entire countries offline.
Back then, an internet (lower case “i”) was a small internal network of computers that communicated with each other.
The World Wide Web, being a massive collection of computers across the globe that are interconnected, quickly earned the title of “THE Internet” (upper-case “i”), to differentiate it from smaller isolated networks.
“World Wide Web” turned out to be a mouthful to say, so we replaced it with “the Internet” instead. Although most websites still start with “www” to represent their global reach.
Nowadays, we’ve stopped using the word “internet” to describe smaller networks, so the word mostly just refers to the global network. And as such, if doesn’t really matter if you capitalize it or not.
However, I was there when the web became accessible to the public and the nomenclature has stuck, so I always capitalize the Internet when referring to it.
That is an intranet, not internet, and is still applicable as a term. You just hear people say LAN more these days.
The world wide web was always just one part of the internet, specifically the portion supported by http. Ftp, email, etc existed then as well, but was not part of the www.
An internet in theory is a network of other computer networks (not single computers). The Internet is the world wide web.
An intranet is a local and private computer network.
The internet is a network of intranets, or more accurately, a network by which computers of disparate networks can connect.
Intra, meaning inside or within. Inter, meaning between or among.
Interdepartmental communication would be communication between departments, while intradepartmental communication would be within a single department.
The inter vs intra is the difference here.
Is this …mansplaining?
I thought I was clarifying without going into detail on the definition of an extranet, I don’t even know how I’d assume gender?
no, the internet is not the world wide web. www is just one of many services provided on the internet and it can be used on the intranet that is completely cut off from the rest of the world.
there is a terminology question then if it is still really the world wide web or rather small web, but the fact stays that services provided on http protocol and internet are not the synonyms. same as mcdonald is not asynonym for “a restaurant” even if specific person may not have visited any other restaurant in their life.
Well, this is something that felt off indeed. But please explain. So http(s) is the world of http requests, but you can also have other services like ftp, ssh, bittorrent and what not. Is that what you mean? So the WWW is just the global interconnection of web pages strictly, over the Internet? Would this apply to any internet? /genuine
basically, yeah. internet is network of computers spanning all earth. intranet is smaller network of computers. intranet is often more private network under more centralized control of someone, with limited access from outside, that can be operated for example by some corporation or university, accessible only for employers or students (possibly using vpn to remotely connect to the network).
www. is the name of the service - http is a protocol it uses.
e-mail is the name of service - to access it, lot of people use http protocol if you use webmail, or imap or pop3 protocol if you use some dedicated client (like thunderbird, outlook, or others). smtp protocol is used to send the message to another mail server (you may have also been asked to configure it when manually configuring some dedicated e-mail client).
ftp, ssh, bittorrent,VOIP telephony using SIP protocol, IRC are other useful services. all these services can be run on network of any size, internet or intranet.
for example majority of modern doorbell systems are running on sip protocol and they are basically small VOIP phones running primarilly on a limited intranet in one specific building. but if that local network has access to the internet, they can have, due to nature of what they are, an option to forward that “call” to any other telephone number in the world in case no one picks it up at home.
small web-developers routinely run their own web-server of their own desktop, which may only be accessible locally, from that one computer or their small home network, to test the web pages they are developing. whether it is still world WIDE web is funny academical question then, because that web is not very wide in such case.
That’s what I was told too, but I never once encountered anybody who used the small-i “internet” term. I heard “network”, or “intranet” or often topology-related things like “the token-ring network”. For a network of networks, I’d hear “WAN” or “external network” but never “internet”. Maybe that’s just me, but I suspect that small-i “internet” was never really a term that was widely used, if at all.
It still routes around damage, but if all the roads are closed you can’t get in or out of somewhere.
Cut cables mostly just slow the internet. Probably very few remaining places without plenty of redundancy.
We had to write angry letters to our children’s school about 5 years ago to get them to stop teaching taste regions. It’s really baffling.
Wait, that’s not a thing?
My whole life is a lie.
I remember being like 7 and trying that out for myself by touching a lemon slice to different parts of my tongue. I think when I realised that it tasted sour regardless of where on my tongue I touched it to was when I first started questioning authority.
I remember many kids in my schooldays saying the same and being gaslit by the teacher into thinking they tested incorrectly.
Yes! The tongue taste zones experiment was my introduction to gaslighting. I guess I’m thankful for that.
at similar age, a teacher told me there can’t be polygon bigger than 360-gon, because that would be a circle. i wasn’t of course in a place to fight with her, i just thought “wtf, how dumb is this bitch?”
The “tongues have taste zones” thing is the only thing that comes to mind.
Also “the 5 senses”. It depends on how you define “sense” there’s at least a dozen to over 20.
Holy mackerel!
Humans have a lot more than 5 senses.
Edit: I had to look it up, because I knew one or two could be more accurately considered multiple (taste zones and such) but I didn’t realize just how many! Wow! Thank you.
Feel like a lot of the “myths” are also just because you’re not going to teach a 16-year-old about quantum mechanics to explain why table salt exists
Well there are deepening levels of understanding depending on the learner’s pre-existing understanding of the world (e.g. matter > atoms > protons/neutrons/electrons > fermions), and there are things that are just plain incorrect, that were assumed to be correct, because science advances (e.g. Pluto is a grey ball of boring nothingness very similar to Mercury).
It isn’t?!
You have to be shitting me… Pluto is a fucking Care Bear planet:

Been through Discworld three times but hadn’t read The Science of Discworld. Know if it’s any good?
I recall liking it well enough at the time but Lies to Children is honestly the only concept in it that was new to me. It’s a decent enough Unseen University side story but that’s just the framing for talking about real world physics.
Where else are you going to find another Discworld fix though?
so what you’re saying is that this is ageism. And we are infantilizing individuals irrespective of their experience and actual understanding.
Never been a big fan of children, but they fucking love me, even if I’m clearly annoyed at the time. I was asking my ex-wife about this mystery. “You don’t talk to them like kids, you talk to them like little adults and they respect that.”
She was right! I talk to them like adults that simply don’t know as much as I do.
The story of how North and South America were settled by the first humans. What I was taught was that the Bering Sea was frozen at the end of the last ice age, and then glaciers opened up and people migrated southward.
The problem is that the timing is too tight and the migration would have to have happened too quickly. Many native groups have long seen this story as flawed, as well.
This was covered in the book “1491”, and at the time of publication, researchers weren’t quite sure what model to replace it with. Probably some of the migration was using boats along the west coast rather than going over land. That book is getting pretty old now, though, and I’m not sure if or where things have settled out.
Racial supremacist preferred narratives favour suppressing evidence that Polynesians could navigate larger Pacific before Europeans could navigate Atlantic. But simply artifacts predate the “land bridge theory timing”
Genetic evidence clearly shows native americans origins are from Siberian people. While there are evidence Polynesians made contact with them before europeans, native americans were already well established for tens of thousands of years before then.

Apple a day.
I recently told my mother that I’m probably the most intelligent person she will ever meet while explaining why her conservative beliefs are dumb as shit and she defensively asked what my IQ is…
I was no contact for the past eight years or so and it was at a family reunion that we saw one another.
I don’t know my IQ, I’m actually a pretty slow learner, and I have horrible test anxiety. But as a polyglot physicist with a dash of perpetual autodidactic inclinations, I’m pretty well informed and I don’t know if intelligence can be measured, but I know it when I see it.
It’s funny that conservatives think quick wit and fast words equate to intelligence without ever stopping to think about the substance.
Objectively speaking, intelligence is considered to be the ability to reason.
Following that line, high intelligence would be the ability to reason well.
However, we humans do well because we specialize. It was discovered early on that we can’t do everything.
One could say it’s our individuality which drives us towards having different proficiencies and the entire chain of schooling would better serve to explore and encourage pursuing such specializations.
Where the means to cultivate proficiency are lacking, the end result will often be incomplete.
That shouldn’t mean there is a lack of intelligence, but that it hasn’t been developed to its potential.
I would say.. the base intelligence remains the same while expectations rise in concert with each own’s path of development.
Life is neither easy nor fair. And opportunities aren’t equal. So i often try to remind myself that perspective changes with experience and as such any standard we set ourselves and others to tend to be laced with personal bias.
and so humble, too! seriously though, this is a major red flag. I rarely find smart people to brag about how smart they are.
also, telling someone that their beliefs are wrong because they’re dumb, and that your beliefs are right because you’re smarter than them, has literally never worked. it will just make them resent you, your beliefs, and anyone they meet in the future who believes what you do. this kind of smugness has been the Achilles heel of Dems for years.

Part of the reason Pluto’s classification hit so hard in the US is that it’s the only ‘planet’ ever discovered by an USian astronomer. That national pride made the 2006 decision sting more than elsewhere. Some of the top figures from the AAS even challenged the legitimacy of the decision afterwards.
(I copy-pasted this comment for the third time even though I don’t like to do that, but it’s important to know where does such reaction come from : partly from pure national pride)
That’s interesting because it’s completely bullshit.

Interesting, because I saw a looot of Europeans being very emotionally involved in the topic!

A bit curious here. How they did prove at first that T-Rex’ vision was based in movement and then how they did prove that doesn’t?
Not sure it’s provable, really, but the idea for T-Rex having movement-based vision is (if I’m remembering correctly, forgive me as it’s been a while) something that came from the Jurassic Park story, and more specifically how frog vision works, since they used frog DNA to birth their dinosaurs.
If I’m remembering correctly vision is movement based, but animals have lots of ways to deal with it. Humans and other species that can move their eyeballs just like vibrate their eyes. But birds like chickens rely more on head bob I think. Couldn’t tell you what kind of muscles a tyranasaur has in its eyes.
Also being wrong on the Internet is the best way to find the right answer. So tell me how I’m wrong.
I could be wrong, and if I am, it’s just an opportunity to learn a new thing. I put what I’ve read elsewhere in the thread.
Have a great day.
It’s also on the wrong side of mostly if not all left leaning democracies. It prefers dictators over center democracies, and will send CIA dogs after any country that starts drifting left.

And the website looks like it’s from the year you input
The US south treated their slaves well. Even in high school, I was like “mmmm you suuuure about that?”
I was fed the line that NORTHERNERS treated their slaves well.
In the era, “spare the rod, spoil the child” was considered good advice. If that’s how even loved ones were treated … slaves treated well? Press X to doubt.
There’s actually a lot of scholarship about how Southern plantation owners developed their child rearing philosophy on a misunderstanding of the Roman patriarchy combined with their newfangled “scientific racism,” conflating the discipline expected for both children and slaves.
All embedded in the modern slang ‘boy’.
Yeah, think about how many men already get drunk and beat the shit out of their wives. The person they supposedly love the most.
Now imagine if they had a slave to take it out on instead.
I have been reading through this book on the matter: The Half Has Never Been Told: Slavery and the Making of American Capitalism by Edward E. Baptist goodreads.com/…/14894629-the-half-has-never-been-…
The descriptions of violence toward slaves is heavily discussed and is quite eye-opening to me, since this is not the version I was taught in school!
Compared to how other slaves were treated around the world, this is relatively true.
The one that immediately springs to mind doesn’t exactly fit the criteria, because it wasn’t even true at the time that I was taught it in public school in Texas. But my history teacher taught me that no real historian called it the “American Civil War,” and that it was correctly called “The War of Northern Aggression.” And, of course, although the Confederacy did want to keep slavery legal, their actual central reason for seceding was “states rights.”
Like I said, both of those are simply lies. Only propagandists call it “The War of Northern Aggression”, and it was always explicitly about slavery.
The sad thing is that I believed and repeated these lies for years after that. Note that, like most people, I didn’t have access to the internet to easily check things myself. Since at the time I had zero interest in reading about history, it was difficult to correct my knowledge.
It has demonstrated, to me at least, the importance of keeping propaganda away from children. The more you lie to children, the harder it will be for them to become functioning adults.
“The atomic bombings were necessary” was something we were expected to internalize as an indisputable hard fact, like gravity and oxbow lakes.
Is it not just the misinterpretation of the fact that the US wanted to end the war quicker to prevent sending more soldiers into a meatgrinder?
You can certainly call that “necessary” to prevent further deaths of US soldiers.
The narrative of the Pacific theater still being an intractable or unbeatable long-term conflict in 1945 was hugely overstated, and also leant heavily on racist notions of the Japanese being “brainwashed”.
Also, most wars could be ended more quickly by committing war crimes, we don’t allow it as a justification when it’s done by the losing side. There was also the option of using them on purely military targets, instead of the middle of a major city, murdering a six-figure number of civilians.
The “brainwashed” thing is somewhat true, at least from the perspective of an outsider, not due to a racial thing, but there is a cultural aspect in addition to the tendency for all sides to be brainwashed by their own propaganda.
But the Japanese propaganda told their soldiers to fight to the death, because if the Americans captured you, it would be worse than death. So, from the outside, they did appear to be brainwashed in that regard. Of course, Americans had similar propaganda making Japanese seem as evil as possible, often in the most racist way, so you’d have to say that Americans were brainwashed, too.
Also, culturally, I think American culture emphasizes each person more, while Japanese emphasizes community more, which means things like kamikaze are easier to sell. And that sort of thing also appears like brainwashing to the outside.
I mean, kamikaze pilots did exist, so there had to be a certain level of what you’re calling “brainwashing”.
And unless it’s also a myth (completely possible), but weren’t there Japanese soldiers found on an island years after the war had ended who were convinced that it was still going on?
I’m pretty sure the largest consideration was keeping the Soviets from claiming land in Asia the same way they did in Europe.
Also, we had this shiny new toy and a war was on; we weren’t going to not use it.
I think there might be an argument for the first bomb, but the second was completely unnecessary.
Not true.
Even after the second bomb, Japan almost faced a military coup in order to keep the war going. en.wikipedia.org/wiki/Kyūjō_incident
They were not going to surrender without a massive show of force because of their culture.
They had literally agreed to surrender before the first bomb dropped, their only condition being that the emperor remain, which the US agreed to anyway.
Can you read?
In our timeline, after two nuclear bombs were dropped, a coup almost happened that would have blocked the surrender of Japan. Would it have been different without the bombs?
I’d be curious if you listened to this what you would think. It does a really good job of laying out the timeline of decisions. I don’t think the atomic bombs were nessecary to draw the war to a close.
youtu.be/RCRTgtpC-Go
Whereas the actual phrase should be “the atomic bombings were necessary to force an immediate total surrender and scare them damn commies before they could take any credit for the Pacific theatre”
I was taught it was about states rights, too. In Kentucky, they were less forceful about calling it the "war of northern aggression.
Did you get taught that some slaves liked being slaves because it meant all their needs were met and they didn’t have to worry about anything?
I don’t recall specifically being taught that, but I do recall believing that was a fact at the time, so it is very likely that I was taught that in class.
I wouldn’t be surprised if there were a couple of slaves like that, but even so, it’s a misleading statement. I actually think that using the truth to lie is a worse sin than just outright lying, because it’s easier to mislead more people like that.
Somewhere Bibi is frowning sternly at you
I had a college professor, Honors US History, teach us that the Civil War was about trade, an agrarian society against an industrial society. Which makes sense and is true in part, but I wish I had known to bring up the various state letters of secession naming slavery as the #1 concern. LOL, Mississippi’s is a doozy.
The texas schooling system is horrendous.
Most texans are genuinely dumb as shit because of how they’ve been hamstrung by their “education.”
When I went to grade school, I think it really depended on the local school district. I was lucky enough to grow up in a nice area with well-funded schools, and I have relatively few complaints about the education I received. However, in doing school activities, I had the opportunity to see schools in poorer districts, and there was a distinct difference.
At the time, I didn’t think too much about the difference, except that I didn’t feel as safe in some schools.
But looking back… Now I know why parents always shop around for better school districts, because there are some places where it would have been far more difficult to get a decent education.
That’s my knowledge from many decades ago. Maybe it’s gotten worse since then.
Similarly, in the US Northeast, I learned about the civil rights movement as a solved problem, and that slavery was basically the only (and long gone) system of oppression we’d had. “Black and brown people have their equal rights now, carry on!”
Bears sleep for their entire hibernation and recycle their waste.
Bears do not hibernate, they enter Torpor
Isn’t torpor just the scientific term for hibernation, or are they distinct?
They are similar, but Torpor is involuntary, hibernation is voluntary. Torpor is for short periods of time, hibernation is for long periods. Torpor drops the body temperature just a little, hibernation drops body temperature significantly. Torpor allows an animal to wake up and move around minimally (like to get food/eat) while hibernation does not.
Wash your chicken before cooking. Don’t do this, it just spreads salmonella all over your sink.
I thought this wasn’t about actually using a sink and water, but rather, using lemon juice to cover the chicken as the enzymes break up the protein and tenderize the meat?

Buy me Bonestorm or go to hell!
See, I was told that too, but no one bothered to explain what that means. I still have no idea what that actually means. What is a powerhouse?
When cells devide there’s a top cell and a bottom cell, the bottom cell is where the powerhouse is generated
Now Dennis, I hear speed has something to do with it.
Cells can’t use the energy from sugar directly. The mitochondrion turns the sugar into another molecule that other organelles can use for energy.
Well, they can, but it’s not very efficient. They produce 4 atp at the cost of 2 atp. The mitochondrion generates 34 atp from pyruvic acid at the cost of 2 atp.
Keeping in mind those numbers are vibes and not exact
Friendly neighborhood microbiologist here. You’re right except for one thing: most cells can use sugar directly through anaerobic respiration. Mitochondria facilitate aerobic respiration, which utilizes oxygen and is far more efficient, albeit a bit slower, and produces carbon dioxide as its end product.
Fun fact: ever wonder where your weight goes when you lose weight? CO2. You literally breathe most of it out.
I can get as nerdy as you want if anyone has any questions.
Edit: another cool one! Part of the process that regenerates ATP from ADP is ATP synthase. Look it up! It’s literally a little biological waterwheel that utilizes a chemical gradient, established by the mitochondria, to smoosh ADP (adenosine DIphosphate) and a phosphate back together into ATP (adenosine TRIphosphate).
Maybe the way you do it. I lost 5 pounds this morning, you wouldn’t want to breathe.
On that (brown) note: most of the solid part of shit is actually (dead) gut bacteria, not food waste
Well tough guy, this morning was an oatmeal surprise swirl, with carrots, two inches above the waterline. In a Crane Galaxy #3251D701100, you do the math.
This is why partially why fiber helps with bulking and pooping. Fiber is “fiber” because it’s made of things we can’t digest, but our gut microbes can. One of the byproducts of their utilizing it is SCFAs, short chain fatty acids. These confer various benefits like reduced inflammation and enhanced mucous production, which helps you drop a deuce.
Feeding your microbes also means you grow more of them, which makes your turds bigger and easier for your intestines to push along.
Yet another fun fact: ruminants like cows ferment otherwise indigestible plant matter in their guts, breaking it down and growing absolutely huge quantities of microbes in the process. Then they digest those microbes. That’s how they get enough protein. A cow is a mooing, shitting house of horrors if you’re a microbe.
BRB. Hyperventillating to test a theory…
(Going to assume this just results in a smaller quantity of calories processed per breath before anyone get’s all sciencey on me.)
It’s too hard to try to manually control a fast breath rate like that. What you want to do is to naturally push that up by doing a bunch of physical work so that you’re breathing heavily. Then you’ll be exhaling lots of carbon dioxide!
What would happen if I got ATP injected directly in the blood stream? And what about the stomach? Skin?
Depending on the concentration, it would hurt as it’s a bit of an acid, plus ATP outside of the cell is one of the mechanisms that drives inflammation, but it won’t give you extra energy or anything.
ATP is used to transfer energy more than store it, more like a wire than a battery. The average adult has about 250g of ATP in their body (for my fellow Americans: about one rather chunky hamster) but it’s recycled about 200 times a day, so would require 50kg (6 watermelons or two average labradoodles) if it was used and discarded.
ATP has been around since the beginning of life or near enough, and evolution is a deranged, cat-piss-soaked hoarder that makes use of whatever is already lying around, so ATP also does several things beyond energy transfer. This also means where ATP is allowed and in what quantity is fairly controlled. To that end, there’s a class of enzyme called ectonucleotidases that’s found on the outside of cells. One of the things it does is keep the level of circulating ATP and things like it low, so whatever was injected would get chopped up pretty quick.
It just means it’s the system that turns food molecules and oxygen into energy for the cell. The cell itself doesn’t know how to do this which is quite spectacular when you think about it. So if the mitochondria died the cell would die.
There are human cells without mitochondria, and plenty of energy chains outside of mitochondrial action.
There are, in fact lots of them: your red blood cells, for example.
Mitochondria are more efficient at energy production, not the only source. Red cells use glycolysis.
You as a human organism would die pretty fast because you need that more efficient energy production but a lot of your cells would be fine until the effects of the system collapsing around them go into effect.
Don’t think about that metaphor too deeply.

Yes. We did this experiment in school, too!
I can confirm that a six year old with a sugar cube can at least throw some skepticism at this one.
I was told I must be doing the experiment wrong.
I did get a quick preview about education, gullibility and gaslighting on that day.
The idea, to me at least, wasn’t that the regions were completely distinct, merely dominant.

On the lemmings one, have you never seen hexbear?
I thought everyone knew the lemmings thing was made up. But it’s become a bit of a meme nonetheless.
More extracts from that same podcast:
The lemmings thing never made sense to me until I found out what the film crew did to them. There’s just no way a species that susceptible to mass suicide could survive long term. They would have gone extinct long before the invention of bored documentarians.
I don’t think there’s a time when everyone knows something
What about the BBc documentary with the spaghetti trees?
I actually learned the lemmings thing from the windows 95 era PC game “Lemmings”. This is also how I learned that lemmings have green hair!
Let’s go! Door creaks
They are skilled with bricklaying and mining tools too ⛏️
I’m not sure if “skilled” is the word, but they get by
fun fact, lemmings was developed by a little studio called DMA designs, which later changed name to Rockstar North, and is nowadays most known for the GTA games.
Huh. TIL.
That is indeed a fun fact!

The economy works and real estate is always a good investment. Also, the best thing that can happen to a nation is to be defeated by the US, because the US will then rebuild their infrastructure. The only example that teacher would cite was Japan.
Fm radio travels in waves while am radio travels in beams. This wasn’t a science teacher though. This was a media teacher’s wisdom.
The rebuilding thing was a plan specific to WWII. They wanted to avoid the issues that the end of WWI brought to keep another war from happening a couple decades down the line.
The US also wanted an ally in the area who was into capitalism. Similar to how SK got a lot of support in building their infrastructure, but they went even farther into capitalism. Both countries are really depressed now.
He was trying to rationalize why Bush II’s wars weren’t going to be bad for them. In both cases, completely ignoring the huge loss of life that incurred.

I can’t say I’ve ever heard the one about classical music making people “smarter”, but it would not surprise me if some music is simply more distracting than others. Most classical music is inoffensive enough to the ears that it’s ok to use as background noise, and the lack of lyrics avoids distracting language processing.
What I’d be more curious about though is if there is any significant impact to quality of work during tests/study time/reading time with background noise like classical music versus just having dead silence.

The food pyramid for sure. I’m not sure if it was taught outside the US
This one is ongoing. It gets modified a bit whenever some industry or another pays enough, but it’s still misleading kids and educators to this day.

Because of Nunavut, or something else?
.
Yup. Nunavut in 1999.
Five senses; taste, touch, smell, sight, hearing, acceleration, temperature, body configuration, pain, balance, time, hunger…
Isn’t acceleration just a sense of balance? Like you feel acceleration because the whatever fluid moves in your ears due to acceleration which is the same as balance.
I guess so, but similar to how a lot of taste is actually perceived via smell? I suppose linear and angular acceleration could be two separate senses which encompass the sense of balance.
Eh, it’s not really similar though. Yes, a lot of what we think of as “taste” is actually perceived via smell. But separately from that, there is actually a phsyiological sensation of taste that is unrelated to smell, i.e. the five basic tastes: sweet, sour, salty, bitter, and savoury.
Whereas there isn’t really any meaningful distinction between the sense of acceleration and balance. They’re exactly the same sensation, and the mind only knows which one you’re actually experiencing by cross-referencing what your other senses tell you. If you’re in a situation where these other senses are unavailable, people generally can’t distinguish whether they’re accelerating or off balance.
This has led to a number of plane crashes in history, in situations where pilots are in dense cloud cover and can’t see the horizon. During stressful situations, if they forget to look at the artificial horizon display, they think the plane is pitching up, and therefore try to pitch down to correct, when in fact the plane is accelerating (due to already being pitched down), resulting in a crash.
well, theres the sense of taste, referring to sweet, salt, sour, bitter and umami. then separately theres the sense of smell, sensing what we call aromas. These are two separate senses.
Our perception of taste could be argued includes the two senses
i’d say the somatogravic illusion being a thing kind of proves you right.
it is why kobe bryant helicopter crashed. the pilot lost in a fog thought he is going up, when he was just accelerating down really fast. there is air crash investigation episode about it.
I was going to say you have a static sense of what orientation you are in, e.g. you can tell standing up Vs lying on your front/back/side without relying on other senses and that feels different to the sensation of moving…
But thinking about it I guess the orientation sense is just detecting acceleration due to gravity?
Acceleration, temperature, body configuration (positioning), pain, balance and hunger are all related to touch in one way or another.
Time, however, is legit. Along with emotion. Maybe you could call the 6th sense cognition?
In theory we can break down the sense of sight into subcomponents, too. It’s only the visual cortex that processes those raw inputs into a coherent single perception. We have two eyes but generally only perceive one image, even if the stereoscopic vision gives us a good estimate of distance, and one eye being closed or obscured or blinded fails pretty gracefully into still perceiving a single image.
We have better low light sensitivity in our color-blind rods but only have color perception from our cones, and only in the center of our visual field, but we don’t actually perceive the loss of color in those situations.
So yeah, someone putting a warm hand on my back might technically set off different nerve sensors for both temperature and touch, but we generally perceive it as a unified “touch” perception.
Similarly, manipulating vision and sound might very well throw off one’s proprioception, because it’s all integrated in how it’s perceived.
Proprioception (body config) is actually feedback from the muscles.
Also they forget or were unaware of the most interesting sense: CO² chemoception. It is how our lungs tell if we need air.
And interestingly: no sense for wetness.
Facts.
Getting the washing off the line…time to play “is it still wet, or just cold”
Walking/riding in a thin rain coat, the sensation of rain telling your body you’re completely soaked, while dry as a bone underneath.
You are missing CO² chemoception. Our lungs tell us if there is a lot stale air, but not if we are in a pure nitrogen environment.

Food wheel was taught in elementary school. As were the taste bud “zones” and the American Dream.
We had the Food Pyramid here in Canada, which is very similarly a lie pushed by the dairy and grain industries and not linked to any real health benefits.

That whole “got milk” campaign was a load of bullshit.
It turns out only about 30% of the global human population is able to even digest milk.
man i cant even have my mocha frap without oat milk
That, and most traditional dairy consuming European cultures never actually drank milk. They made cheese and butter, then poured the remainder in the pig trough to turn those calories into pork.
The most delicious of calories.
Absolutely. Mainly a problem of conservation of raw milk.
Mainly a marketing campaign by the dairy lobby
The Nuer (a cattle-herding people from Sudan) would pour milk into gourds and add cow urine and leave it in the sun for months. I love eating food from around the world but that is one thing I would pass on. They never drank milk, but if they needed liquid calories they would poke a hole in a cow and drink some of their blood.
Yeah but those avacadoes…
In the US, Trump would demand this site be “de-woke-ified” to remove “conservative bias” by having any conservative fact disproven removed from results.
I guess the big one for me is the whole Mozart for babies thing. It wasn’t Mozart’s music making babies and young children smarter, it was a combination of more affluent parents or at least parents with college plus educations having time and income to spend on enrichment activities.
Yeah, but that doesn’t stop baby toy markers from including that shit in every product
Oh, thanks! That makes so much more sense!
On a tangential note, I find hilarious which songs my toddler picks up and which ones are immediately forgotten. Somehow APT and Hey Jude are the shit, most of everything else doesn’t stick. Wonder why…
I think it’s just songs with the right kind of beat that they like. My sister’s kid is very partial to Uptown Girl, of course she doesn’t know the lyrics but she can sort of sing the tune. It took me a while to work out what it was.
My (3.5 year) nephew also loves APT. His other go to is These Boots Are Made for Walking.
Most of what I learned about genetics is incorrect as when I graduated we thought DNA ran the show.
We were also wrong about why the USSR fell (not a huge surprise)
Why did we think think the USSR fell? Also DNA does run the show…damn, my genetics knowledge is shit. Apparently we graduated the same year 🤣
I graduated when people accepted Gaidar’s propositions whole cloth and now we blame Gorbachev a lot more than we did in 2000
mRNA runs the show
The most common belief was that it fell because Ronald Reagan ordered Gorbachev to “tear down that wall”.

I still want whoever decided that “I before E except after C” should be taught to children locked up. Im almost 50, and I still spell “their” wrong if I dont concentrate.
“I before E exthept after ‘th’” should do the trick. Just have to remember that the last part is pronounced “thee”.
“I before E, except after C, or when sounded as ‘ay,’ like in ‘Neighbour’ and ‘Weigh.’”
…Or when running a feisty heist with their weird, foreign neighbour, Keith.
They taught you that in school?
I learned that in middle school. It was from a kid on the bus but it was still middle school.
You do your most important learning outside of the classroom
lololol
Believe it or not, this rumor actually stretches all the way back to dianunzio from Italy in the 1940s.
Oh so we graduated almost at the same time it seems.
He responded to this rumor in his autobiography saying “If I really got my ribs removed, I would have been busy sucking my own dick on The Wonder Years instead of chasing Winnie Cooper. Plus, who really has time to be killing puppies when you can be sucking your own dick? I think I’m gonna call the surgeon in the morning”
Brian Warner can fuck right off tho

KETCHUP IS A VEGETABLE!
Fruit and vegetables being separate categories: Fruits are actually a type of vegetable. Additionally cucumbers are melons.
Cyan being a light blue: It is actually 50% green.
Simple machines are fundamental: They completely ignore compliant mechanisms and aren’t atomic. Actually atomic mechanisms would be defined by the type of force, the shape, and the compliance.
The only form of Socialism is Marxism and Communism and Capitalism means markets: Look up Mutualism or Syndicalism.
Basically everything with pop psychology.
I am sure there are more, but these were just top of my head.
What high school did you go to that they were discussing Marxism and communism. Most schools don’t really get that advanced and don’t go much beyond teaching about the major wars.
Rome didn’t have special rooms for people to vomit in, then resume feasting.
Soviet blocking brigades weren’t machine gun nests set up to mow down retreating soviet soldiers.
Vietnam had a regular army, it wasn’t entirely a guerrilla force.
Did they not teach that North Vietnam (and therefore the NVA) existed?
Haha, not really.
Well, yes they did, but if one only pays attention in hollywood movies and not in school they wouldn’t know it.
Kind of. That’s not really reconciled with the l general impression that the US won every single battle, and couldn’t find any more enemies to fight, because the Vietnamese would run away and hide in the woods or among the locals and the US only lost the war at home.
When the real story of Vietnam is: we shot a bunch of Vietnamese people and then dropped our entire back stock of WWII-era bombs on them (and their neighbors) and then up and left and now they make our shoes for us.
This is more like not being taught anything other than that they had “vomitoriums,” without being told what they were. Vomitoriums existed. They still exist, too. It just means a large opening or passageway. Like the entrance/exit to the colluseum.
No, they literally taught that the romans feasted so much they had special rooms for vomiting in. One of my aunts was incredulous that it was no longer taught, and insisted she had been to rome and saw the vomitoria, and remains convinced that it’s just some new theory by some fringe historian.
Every subject other than English and Math have tons of things that were wrong, misunderstood, or made up back when I was in school. 😩

it’s all just fascism with chrome plating and a spoiler
Nah, not tacky enough. Trump would go with gold.
I’m not sure that Russia really counts as anything other than an actual dictatorship. It’s not like there’s a free and open choice and people just keep voting against their own interests like in the US, the elections are of course rigged and there are no opponents anyway. Anyone that might stand against him gets assassinated.
Of course Trump probably will try and go that route as well, but he hasn’t done it yet, and he hasn’t consolidated his power there are still people in positions of some authority pushing back against him.
Hence why “hybrid regime” seems like the best descriptor of the US right now.
Work hard and you will be rewarded and taken care of. LOLLLLLLLLLL.
The fact that we thought Pluto was a planet seemed absolutely insane at the time but none of the kids could question the adult in the room when the stupid rock is literally not even staying in its own lane
That’s a definitional question, though, is it not? I don’t think any facts actually changed.
Okay then maybe the electron shells model of an atom. That was taught as fact and it’s definitely not true even though it’s still useful
Yes. Ceres was considered a planet when discovered in 1801 and around the 1950s began to be classified as an asteroid. It is now considered a dwarf planet like Pluto. It’s the largest thing in the asteroid belt but is still sort of planet shaped.
It doesn’t help that planet has such an incredibly vague definition. Earth is a planet but so is Jupiter but other than being spherical they don’t have anything in common. In terms of similarities, Pluto is much more like Earth then Jupiter is like Earth, at least Pluto has a solid surface.
It’s not vague at all. It’s a classification that needs to meet three criteria. The lack of this classification is why it was taught that pluto was a planet, but once these things were formalized in 2006 it became clear that pluto no longer met the criteria.
en.wikipedia.org/wiki/IAU_definition_of_planet
Yes and I know that Pluto fails the final test, although it’s a bit difficult to really to say in what context that matters, because it’s in the Kiper belt which is incredibly diffuse anyway.
But actually astrophysicists have long since said that the established definition of planet is far too vague and needs tighter definitions
I went through the two websites posted here for graduation year 2008. The only incorrect thing I was taught that I still believed was:
“Learning styles (visual, auditory, kinesthetic) determine how you best learn”
False. Huh.
Those were disproven long before then. They are interesting to think about as different sensory inputs to engage, but are complete nonsense as far as learning styles.
…So what learning styles are there?
Teacher here. Now we get taught that the main mechanism for learning is attention, usually triggered by a combo of motivation and diversity (as opposed to monotonicity). So you should hit a variety of teaching styles not because different students react better to some of them but because it triggers their attention and motivation mechanisms. We also get taught that switching too much tires the students out, so we should pick some 3 types of activities and rotate between them, tending to reduce the traditional lecture style.
Oh man, I could go on an in infinite rant about all this… but well, this is the recent theory. (Dated 2024)
In my world I’d adopt the West Wing teacher philosophy: competition to be a teacher should be fierce and pay should start at six figures. You all are literally shaping the world’s future and yet many teachers I know have to purchase their own supplies and deal with thick headed administrators that place politics over pedagogy.
Thanks for what you do. I appreciate your work.
I teach at university level. Fixed positions are few and far between, pay is okay (if you somehow forget all the seniority you need to get to this positions), number of teaching hours is very high, there is no incentive to teach well. One of the results is that you are not selected for being a good teacher, but for the other components of your cv.
I just picked up a book on this! There is, of course, an incredibly racist history to the use of these concepts.
You Are Not a Kinesthetic Learner
My brother had to do that for the military at one point. I don’t know what the point was because apparently nothing ever came of it they just did the tests got their results and then apparently everyone forgot about it, because everyone carried on getting trained in exactly the same manner anyway.
Oh yeah it never was applied. I just remember one of my high school English (Language Arts) teachers talking about it.
I did too many drugs in high school. I don’t remember a lot.
1987 Edison was a genius and invented everything, Turns out he was actually the Elon Musk of his time.
AND he electrocuted an elephant.
He was trying to prove that electricity was dangerous. Even at the time though a lot of people pointed out that the voltage used was not the voltage used in mains electrics so it was basically a pointless thing to do and people quite upset about the elephant. He did receive a fair amount of bad press for it.
He wanted to show that AC lines with their heigh voltages are dangerous, as he sold low voltage DC power.
Edison’s electricity was the same 110volts. But it it was 110v from generators to peoples homes and thus suffered greatly from resistance losses.
Telsa’s AC however used high voltages for distribution and step down to 110v at the final destination, so the resistance losses were much lower. Edison’s propaganda conveniently glosses over that fact.
Oh, it wasn’t just elephants. He did it with dogs, monkeys, etc. This wasn’t a one-time thing, he provided this “demonstration” on a variety of occasions.
All because he wanted the world to adopt his standard for electrical transmission, direct current (DC) instead of Nikola Tesla’s alternating current (AC).
Tesla was a brilliant engineer and inventor. He knew EXACTLY what he was doing (though later he did get a little nutty). Edison just yelled at engineers he hired to do work for him.
I am so sad that Tesla’s name has been ruined. He was wildly intelligent and though he was a prominent figure in his prime, he died broke. It’s not bad enough that he went out like that, now we have a fucking clown pissing on his grave by using his name to sell his bullshit nazimobiles.
Edison being a giant dick of a patent troll is one of the main reasons Hollywood exists. I’m not sure Musk has anything that impactful on his resume.
Intellectual jokes like this are one of the reasons I’m on Lemmy.
I’d say PayPal was a pretty big deal but I’m not sure what his level of involvement was
Don’t get me started. He did not invent the lightbulb. Did he “perfect” it? Maybe? But only after trial and error of 100’s of filaments including human hair.
Can it even be said that it was perfected when later we switched from carbon filament to tungsten, and from there to halogen-surrounded tungsten.
And on the other side, Edison’s lamp wasn’t even the first one to be mass produced and commercially sold.
There’s a certain style of education that really wants to draw a hard line between “before the thing” and “after the thing”, and credit its invention to a single guy. But really the line is quite wide and fuzzy.

“What you were taught
“Flu shots give you the flu”
What we know now
A common misconception…
Updated understanding emerged around 2020”
Updated for whom? Anti-vaccine idiots?
Well some shots do work like that. But you usually don’t get symptoms unless you are immunocompromised and it’s a live (but weakened) version of the virus.
They were just a little wrong, “Flu shots give you a flu”.
There are 2 types of these shots essentially:
Of course, if your immune system is weak, the processed pathogen can be enough to give you quite a bit of a problem.
I know there are different types of vaccines, but really, experience should be enough to prove this assumption wrong many times over. I guess people just don’t get their flu shots…
I think the biggest one that was drilled into us constantly, especially about WW2 and Nazis was
“ Those Who Cannot Remember the Past Are Condemned To Repeat It”
This was a load of shit as evidenced by what is going on in the USA right now and other parts of the world. The real lesson should have been to push back the second a nazi takes an inch as they will take more if you play the nice and tolerate. Not everyone is well intentioned.
I had this really awesome kind of angry and nihilistic history teacher in H.S. who offered an elective course that studied the repeated patterns through history leading up to genocide. It covered Armenia, Rwanda, and the Holocaust.
I don’t know if it was just the fact that we looked at the repeated overlaps between human behavior vs just memorizing historical events, but if more people took a course like Crimes against Humanity maybe they would learn to spot those clear patterns of human behavior that somehow happen over and over again without anyone noticing.
Yep, the Holocaust didn’t happen overnight. It always starts as a slow slide into genocide, but once it picks up steam it turns into an avalanche. It drives me nuts that people keep pretending we should be entertaining any of this as just normal politics. The reaching across the aisle bullshit was insane a year ago (and really 10 years ago), but at this point it is literally enabling this shit to happen. You’re a collaborator.
That quote is being proven true right now though?
People don’t really remember what happened with the nazis. Most of the people who actually lived that past are dead now.
And the vast mojority of people lack enough empathy/understanding to be able to ‘walk a mile in their shoes’ as it were and extrapolate the horrors from the most readily available histories.
The quote isn’t
That’s the ol’ Oracle of Delphi phenomenon of misreading the claim: the claim still holds if everyone is doomed. Also, are you claiming MAGA remembers shit?
Not sure it is about remembering as much as how one’s brain works as some are more emotional than intellectual.
USA is a democracy
Is it not?

It certainly wasn’t
Sure, some are still taught. Like you can catch a cold from being in the cold.
My mum says this all the time, haven’t the heart to correct her though
I always understood it as your immune system gets weaker from being in the cold and makes it easier for viruses and such to propogate in your body. We’re constantly fighting off minor infections and disease, and thankfully our immune systems are pretty strong…cold does not help it.
I’d say this one is sort of true…in the right context.
I thought the opposite. That when you’re cold, and your body releases Norepinephrine, that it re-enforces your immune system.
Which makes sense to me from a personal experience. I like to run around in the snow in tshirt and shorts and embrace the cold. I very rarely catch colds and always thought it was genetics and not a product of environment
My wife likes to say that so she can keep believing that you can catch a “cold.”
No cold virus. No cold.
In my moc-GCSE year(s), my science teacher was so confident that blood was blue in the veins, I called her out on it but she was so adamant about it.
When I graduated highschool, the idea that some dinosaurs had feathers and evolved into birds was still “fringe science”.
When I was in school, we were taught that vaccines work. /s
I was taught that serious academics favored Support Vector Machines over Neural Networks, which industry only loved because they didn’t have proper education. oops…
also, Computer Vision was considered “AI-complete” and likely decades away. ImageNet dropped a couple years I graduated. though I guess it ended up being “AI-complete” in a way…
Before AlexNet, SVMs were the best algorithms around. LeNet was the only comparable success case for NNs back then, and it was largely seen as exclusively limited to MNIST digits because deep networks were too hard to train. People used HOG+SVM, SIFT, SURF, ORB, older Haar / Viola-Jones features, template matching, random forests, Hough Transforms, sliding windows, deformable parts models… so many techniques that were made obsolete once the first deep networks became viable.
The problem is your schooling was correct at the time, but the march of research progress eventually saw 1) the creation of large, million-scale supervised datasets (ImageNet) and 2) larger / faster GPUs with more on-card memory.
It was fact back in ~2010 that SVMs were superior to NNs in nearly every aspect.
Source: started a PhD on computer vision in 2012
HOG and Hough transforms bring me back. honestly glad that I don’t have to mess with them anymore though.
I always found SVMs a little shady because you had to pick a kernel. we spent time talking about the different kernels you could pick but they were all pretty small and/or contrived. I guess with NNs you pick the architecture/activation functions but there didn’t seem to be an analogue in SVM land for “stack more layers and fatten the embeddings.” though I was only an undergrad.
do you really think NNs won purely because of large datasets and GPU acceleration? I feel like those could have applied to SVMs too. I thought the real win was solving vanishing gradients with ReLU and expanding the number of layers, rather than throwing everything into a 3 or 5-layer MLP, preventing overfitting, making the gradient landscape less prone to local maxima and enabling hierarchical feature extraction to be learned organically.
No, you are correct. Hinton began researching ReLUs in 2010 and his students Alex Krizhevsky and Ilya Sutskever used it to train a much deeper network (AlexNet) to win the 2012 ILSVRC. The reason AlexNet was so groundbreaking was because it brought all of the gradient optimization improvements (SGD with momentum as popularized by Schmidhuber, and dropout), better activation functions (ReLU), a deeper network (8 layers), supervised training on very large datasets (necessary to learn good general-purpose convolutional kernels), and GPU acceleration into a single approach.
NNs, and specifically CNNs, won out because they were able to create more expressive and superior image feature representations over the hand-crafted features of competing algorithms. The proof was in the vastly better performance, it was a major jump when the performance on the ILSVRC was becoming saturated. Nobody was making nearly +10% improvements on that challenge back then, it blew everybody out of the water and made NNs and deep learning impossible to ignore.
Edit: to accentuate the point about datasets and GPUs, the original AlexNet developers really struggled to train their model on the GPUs available at the time. The model was too big and they had to split it across two GPUs to make it work. They were some of the first researchers to train large CNNs with GPUs. Without large datasets like the ILSVRC they would not have been able to train good deep hierarchical convolutions, and without better GPUs they wouldn’t have been able to make AlexNet sufficiently large or deep. Training AlexNet on CPU only for ILSVRC was out of the question, it would have taken months of full-tilt, nonstop compute for a single training run. It was more than these two things, as detailed above, but removing those two barriers really allowed CNNs and deep learning to take off. Much of the underlying NN and optimization theory had been around for decades.

Oh I’ve got a good one. Learned in the American south. Supposedly the American Civil War was not fought over slavery, but differing railroad track widths. Slavery was a minor detail that was a scape goat for the north to force the south to use its standard railroad width.
lol
The American South (several institutions, not necessarily the ppl) will attempt to make any minor issue as the root cause of the Civil War, except for the slavery issue.
Afterall, slavery and racism wasn’t that ingrained in the society. If you look past the court cases, extra judicial killings, lynching, riots, coups and massacres.
It’s not just about slavery. There was also state’s rights (to slavery), and the economic disparity (turns out free men work harder than slaves?!), and a clash of religious ideals (people that interpret the Bible as pro-slavery vs people that believe benevolence requires abolition). There were even one or two spots where water usage rights and federal funding were in controversy.
.
So straight up timeless facts only?
Unironically, that sounds like a great task for AI.
Great for automatically generating falsehoods; this is true.
Well, I let you be the judge. Here’s a list of outdated facts that were commonly taught before the year 2000 but have since been updated, courtesy of ChatGPT:
Science / Space
Pluto is a planet.
Back then, Pluto was still the 9th planet. In 2006, the International Astronomical Union reclassified it as a “dwarf planet.”
The universe’s expansion was slowing down.
Many textbooks still suggested the universe might eventually collapse in a “Big Crunch.” In 1998, evidence of accelerating expansion was found, but it hadn’t fully filtered into school curricula by 2000.
Dinosaurs were cold-blooded and scaly.
In 2000, the “feathered dinosaur” revolution was just starting. Today, we know many theropods (including raptors) had feathers and were likely warm-blooded.
The continents “drift” slowly but are mostly stable now.
Continental drift was taught, but the understanding of plate tectonics was less developed in school-level detail. We now know tectonic activity reshapes Earth far more dynamically than was often taught.
Biology / Medicine
The human genome was incomplete.
In 2000, the Human Genome Project had just released its first draft. Many textbooks underestimated how complex genetics really is — for example, they suggested humans had ~100,000 genes, but it’s actually about 20,000.
Ulcers are caused by stress and spicy food.
That was the classic teaching. By the 1990s, scientists had already shown that ulcers are often caused by H. pylori bacteria, but the update wasn’t in most classrooms yet.
“Junk DNA” does nothing.
The idea that noncoding DNA was useless filler was common. Now we know much of it plays regulatory or structural roles.
History / Social Studies
The internet is a fad.
You may have heard skepticism about the internet being overhyped. Few predicted how deeply it would transform society in just two decades.
Christopher Columbus “discovered America.”
By 2000, it was still widely taught that Columbus “discovered” the New World, though evidence of Norse settlements (like at L’Anse aux Meadows) was already known — just not widely emphasized. Now, school curricula are far more likely to teach about Indigenous civilizations and earlier arrivals.
The Great Wall of China is the only man-made object visible from space.
This “factoid” was common in classrooms, but it’s false. The wall is not easily visible from orbit without aid, while cities, roads, and airports often are.
In an atom, the electrons orbit around the nucleus in the same manner as the planets orbit around the sun.
That’s been debunked for many many decades but middle scool still teaches this model. At least I wasn’t told back then how misleading and wrong that is, only in high school right before graduating the physics teacher emphasized this misconception. I remember how mad she was about it lol. I have no clue how its taught elsewhere.
The Bhor’s model is at least a useful simplification of the atomic structure. What needs taught is that everything you learn before college and intensive narrow topical courses is simplified to the point of being incorrect with the hope that you get enough of an intrinsic understanding of the concept that the less simplified explanation you get next will make sense. I say this because it will still be simplified to the point of being wrong, but will be a step closer to the truth. This is the essence of education.
