B Possible for a particle to diffract around a barrier

  1. Nov 29, 2016 #1
    According to quantum theory it is possible for a particle to diffract around a barrier. Does this explain why I often seem to completely miss a tennis ball? Explain why or why not?

    No. You and your tennis racket and the tennis ball are way too large for quantum diffraction to be significant.

    By the way, you labeled this thread as "A", advanced. That indicates a graduate level understanding of the subject matter, which does not seem to reflect your actual understanding. I have re-labeled the thread level to "B".

    As already stated this has nothing to do with QM :smile:. Tennis is pretty difficult, but fun. I think you have to train more. And observe the ball more accurately (sorry, I could not resist).

    Its not a diffraction phenomena because there is no quantum tennis field.

    it's about the Heisenberg uncertainty principle. I have lots of experimental tennis data to prove it.

    The establishment won't publish it tho.
