It wasn't tongue-in-cheek; most people think you can compress rubber
into a smaller space. I certainly did, and I found it very
counter-intuitive when I learned that you can deform rubber but not
compress it. Try fitting an over-size 'O' ring and you'll see what I
I am of course talking about practical applications, not theoretical
physics. In any case, while theoretical physics used to make perfect
sense in the clockwork universe of Isaac Newton's day, it makes no sense
whatsoever in Heisenberg's uncertain present, especially when you get
into the area of quantum physics. I sometimes think they're making it
all up just to gull us.
