Probability of hand through a wall vs an electron

  1. Oct 27, 2011 #1
    a friend and I were trying to see if it would be more probable to put your hand through a solid wall, or for an electron to be 1m away from the nucleus (consider the electron is the only particle around).

    would this even be possible to calculate?
    what would we do?

    thanks!

    I think the chances that your hand will pass through a wall will be smaller. For even 1 particle to tunnel through a wall, the probability is miniscule, and you have to do that for all ~10^23 particles in your hands.

    But of course the answer depends on the specifics.

    Well, the "wall" could be 1 atom thick...maybe...in which case they may be comparable...XD
