  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 sharp it always looks like shit.

  I want satisfying movie sharpies.

  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)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.

    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

    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.
