Experimentally determine position of electron

  1. Jun 17, 2012 #1
    How do we experimentally determine the position of an electron that is not bound to any atom and far away from all other influences including electromagnetic and gravitational fields? [Edit: what would the apparatus be?]

    We can't.

    It's a bit like determining the position of a bear in the woods. We may have an idea the bear is in there - seen little signs etc - but we don't know precisely where he is. If we lay a bear trap, and the bear walks into it, then we know the position of the bear.
