  • That the eye can only perceive 24 fps is a myth. Plus vision perception is very complicated with many different processes, and your eyes and brain don’t strictly perceive things in frames per second. 24 fps is a relatively arbitrary number picked by the early movie industry, to make sure it would stay a good amount above 16 fps (below this you lose the persistence of motion illusion) without wasting too much more film, and is just a nice easily divisible number. The difference between higher frame rates is quite obvious. Just go grab any older pc game to make sure you can get a high frame rate, then cap it to not go higher to 24 after that, and the difference is night and day. Tons of people complaining about how much they hated the look of Hobbit movie with its 48 fps film can attest to this as well. You certainly do start to get some diminishing returns the higher fps you get though. Movies can be shot to deliberately avoid quick camera movements and other things that wouldn’t do well at 24 fps, but video games don’t always have that luxury. For an rpg or something sure 30 fps is probably fine. But fighting, action, racing, anything with a lot of movement or especially quick movements of the camera starts to feel pretty bad at 30 compared to 60.


  • From the applications section of the Wikipedia article on quantum entanglement:

    Entanglement has many applications in quantum information theory. With the aid of entanglement, otherwise impossible tasks may be achieved.

    Among the best-known applications of entanglement are superdense coding and quantum teleportation.[85]

    Most researchers believe that entanglement is necessary to realize quantum computing (although this is disputed by some).[86]

    Entanglement is used in some protocols of quantum cryptography,[87][88] but to prove the security of quantum key distribution (QKD) under standard assumptions does not require entanglement.[89] However, the device independent security of QKD is shown exploiting entanglement between the communication partners.[90]

    A lot of Sci Fi and other popular media likes to misconstrue quantum entanglement as allowing for faster than light communication so that they can have faster than light communication in their story, often for narrative purposes to make their galaxy spanning epic possible on a human time scale. But as far as we know, faster than light communication is impossible. It doesn’t mean quantum entanglement is useless or not an important scientific finding though.
