You certainly know it, but sharing it for the ones who don’t:
The full equation is E² = (pc)² + (m₀c²)² where E, p, c, m₀ are respectively: energy, momentum, the speed of light, inertial mass. The (pc)² part is kind of a big deal, because otherwise massless particles (like photons) would have no energy.
If p = 0, then the equation simplifies into that famous E=mc².

What I think is funny is that if you assumed E=mc^2 for all particles, then that would mean that red light is lighter than blue light.
This, too: if E = hc/λ and E = mc², then we can combine both as hc/λ = mc². Rearranging this shit you get m = h/λc. Since h/c = 2.2*10⁻⁴²kg*m, you’d get:
Photon colour
wavelength (in nm)
“Weight” (in 10⁻³⁶kg = 10⁻³qg)
red
650
3.4
yellow
600
3.7
green
550
4.0
blue
450
4.9

Einstein initially did write:
If a body gives off the energy L in the form of radiation, its mass diminishes by L/c^2
which got re-arranged to E=mc^2. Although he was aware that this doesn’t apply to systems in motion or mass-less particles such as photons.

Hidden behind all the memeing is a sad truth of the world all of you refuse to face
Humans value the appearance of competence over actual competence. An actor in a lab coat is trusted more than an actual scientist because the actor has spent years of his life appearing to be what he is not, and the scientist is too busy practicing science to worry about appearances
It is why we have a racist reality tv show actor as president
And none of you will take responsibility for your part

You have no idea whether people here take responsibility or do you assume this because nobody else points out this highly simplified analysis?
Humans value the appearance of competence over actual competence.
Ok have you personally taken responsibility for the fact that your media consumption has made your worldview delusional? Nope? Ok then I am not making an assumption, I am stating human nature
Ok have you personally taken responsibility for the fact that your media consumption has made your worldview delusional?
This is a loaded question on the same level as “did you stop beating your wife? Yes or no?”.
But let’s bite: yes.
I come from a scientific background. And you don’t get to keep delusions about something when reality is making you interact with that thing over and over, regardless of the origin of said delusions. You face them, as soon as you step into the uni. And one of the things I often talk with people is how science is misrepresented in media, specially after that clown of the former president of my country started babbling about Ivermectin*.
And, due to the nature of the content of this community, I expect at least some of the other people in this comm to be in the same situation as me - to be from a scientific background (or even scientists themselves) and to try to spread awareness on how media misrepresents science, the scientific method, and scientists.
So your “all of you”? Bullshit.
Unless you’re decontextualising the whole thing to talk about media-based delusions in general, even if the context screams “regarding science”.
(Or perhaps you’ll try to change goalposts and say something like "ackshyually, taking responsibility is something else lol lmao.)
Nope? Ok then I am not making an assumption,
Even if your assumption was true (it is not), it would be still an assumption. You’re still vomiting certainty about something you cannot reliably know, such as what all individuals in a whole group of people do or don’t.
I am stating human nature
I think that both of us know that you’re bullshitting.
*just to point out another assumption you’re voicing in your comment: “It is why we have a racist reality tv show actor as president”. Why do you think everybody here is American?
EDIT: note this topic itself is already a way to take responsibility for all the crap media shows dressed as science. For a start:
what are LadyButterfly, Admetus, klemptor and me doing here, if not highlighting that media grossly oversimplifies Physics?
what I want to know is where do all these stock photos and movies and tv shows get those awesome sharpies that allow you write on windows so crisply? whenever i write on a window with a sharpie it always looks like shit.
My brother in law made a lighted glass board during covid so he could write in mid-air while facing the camera at the same time.
He used light-colored whiteboard pens and a dark background.
All that’s missing was to write in reverse because the camera was on the other side!

I really don’t get why there’s never any effort when doing l this kind of “stock art” math/science.
So many fake chemicals, so many equations that are completely meaningless… all of those t-shirts that say “what part of [UNINTELLIGIBLE SCRIBBLING] do you not understand?”
Is it really that much effort to crack open a linear algebra textbook or look at an actual equation sheet? I always feel sniped by that shit, I tried to read it and figure out what it is but it’s always just a mix of completely random stuff, with half of it truncated to the point of meaninglessness.

The famous equation includes momentum so I always chuckle when they only show E=mc2

Just because it’s simple doesn’t mean people accept it or act to change their behaviors on it
And every facet of life reflects this. The highest paid aren’t the most competent, but the ones with a carefully cultivated appearance of competence
Stop assuming.
