    This doesn't fully explain the double slit experiment. They're missing the even more mysterious part about what happens when the electron is being observed.

  • @trust.it.444
    For me, this is the clearest video demonstrating the double slit experiment. Thank you!
  • @spacet1me
    This is THE BEST video on this on the Internet by fuckin far. Thank you!!

    Warning: quantum mechanics can cause dain bramage, I mean, brain damage.

    Whenever I am giving a lecture on quantum physics, I feel as if I am talking about Vedas. (Spiritual and scientific books of Hindus written down in 5000 BC and an oral tradition before that). I studied matter for 35 yrs only to find that it does not exist- exactly what Adishankara said (a Hindu sage -2000 BC) long back from the upanishads. " All that you see does not exist" - Hans Peter Durr (German Quantum and Nuclear Physicist) 
  • A very inspiring video Clearly explained the concept Thank you very much

    tl;dr Instead of figuring out why the double slit experiment works some dude said, and I quote, "Math, yo.", and came up with a formula to predict where things would end up and said that explains it. So basically it acts like a wave, we pretend it is a wave, but we chalk it up as magical math instead of figuring out why it happens.
  • @deehin3137
    If a particle is moving through a medium that it is creating a wave in, it can interfere with itself as in the double-slit experiment. Its location on the detector is determined by the location and direction of its greatest amplitude before it hits the detector.
  • Here's something I don't know if already been expressed: Think of extra dimensional planes, like a 4th dimension, of the single photon beam, representing itself as an interference pattern out from the extra slit. The slit that doesn't have any photons thru it, has an extra dimensional aspect, paralleling simultaneously with the slit that has the photon beam. Thus creating the interference patterns. So when only one electron is fired at a time thru only one slit over time, those single fired electrons have a corresponding parallel extra dimensional aspect as well, providing the interference patterns. Extra-dimensional space Eg: Tesseract - Hypercube expression; of electron/photon beam.

    A photon is a wave. It travels as a wave, always! But its energy is absorved discretly following a probability distribution.
  • @bavwill
    The electron's motion builds up momentum creating a a wave which eventually ends up carrying the electron to its final location, a marker for one point of that wave. How'd I do?

    what if instead of placing the screen in front we add two more screen on the way from slides to front screen in order to see where the pic or trough hit the up and down screen
  • @bharathp7974
    When we are aiming the electrons individually at one of the splits and shooting, how can any of the electrons go through the other split?
