I'm reading Lee Smolin's book "Three Roads to Quantum Gravity" and finding
it quite interesting. After trying to explain the uncertainty principle he
says on page 36:
"Perhaps this seems a bit abstract. It may also be hard to think about,
because the mind rebels: it is hard to work one's way through to the
logical consequences of a principle like the uncertainty principle when
one's first response is simply to disbelieve it. I myself do not really
believe it, and I do not think I am the only physicist who feels this way."
