You can't skip the story about Niels Bohr at the bottom.
Heh... Considering that all the participants were scientists, I'm surprised they concluded that one event caused the other.
Well, technically, in an s-orbital there is a substantial, non-zero chance of the electron being inside the nucleus.
A classically-behaving point particle with the same charge as an electron would drop into the nucleus, but the wave nature of real electrons forbids it. Due to the uncertainty prinicple, there is a nonzero chance of finding the electron in the nucleus, but to say it is substantial is false.
