I always go for Ĥ|Ψ> = E|Ψ>
I hope Poseidon can beat his evil twin.🙏🏻
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.
I want satisfying movie sharpies.
We used regular whiteboard markers at my previous job. Worked perfectly for that
You want paint pens, not sharpies
Also, they work great only when they’re new.
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!
The famous equation includes momentum so I always chuckle when they only show E=mc2
You certainly know it, but sharing it for the ones who don’t:
The full equation is
E² = (pc)² + (m₀c²)²where E, p, c, m₀ are respectively: energy, momentum, the speed of light, inertial mass. The(pc)²part 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 …BLOODY ULTRAVIOLET IS MAKING ME FAT!
Einstein initially did write:
If a body gives off the energy L in the form of radiation, its mass diminishes by L/c^2
Does the inertia of a body depend upon its energy-content?, 1905
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
all of you refuse to face
Stop assuming.
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.
