The most beautiful experiment in physics!

This video shows the interference pattern of a beam of electrons through a double slit. The experiment is performed with spinning particles showing a wave behavior interpretation of the outcome.

  • "Bouncing" is a concept of macroscopic objects. The electrons can be absorved by the atoms in the CCD and thus detected or simply go through.

  • They mean, that as electrons are sent out only ocasionally, with a large time delay between one and the next, most of the time the microscope is "empty" with no electron at all, and thus with a extremely low probablility of finding two at the same time that could interfere with each other to create a wave interference pattern.

  • Maybe some electrons bounce off the target screen and then inter fear with incoming electrons?

  • at 18 seconds what do they mean? How is there a small chance of finding one electron?

  • @7711ish well of course people don't know what it is about. That is all what free internet is all about. Thank god most people don't know what it is about, hopefully they find it intriguing, maybe even end up in studying physics.

    Just saying it's good that all sorts of people watch a video.

  • @princepunisher welcome to Quantum Mechanics!!

  • :O AMAZING! I dond know what sould I say... :S

  • A fine analogy for teamwork?

  • For those who don't understand, this shows that particles in our Universe can act as both a single individual particle, and together as a wave. This experiment shows just how weird, yet amazing, the quantum world, and our world, is.

  • Most people have no clue what this experiment is implying. If they did this video would have thousands of views.
