We are trying to understand the implications of quantum mechanics. The subject is very old, but we are still learning.
as quoted by John Hogan, in Quantum Philosophy, Scientific American (July 1992)
Concepts like these can seem remote, until you explain with analogies taken from everyday life. But unfortunately some ideas do not lend themselves to familiar analogies.Leonard Mandel
It's kind of interesting to show that the strange features of quantum mechanics are actually observed. We still don't totally understand what it means.Leonard Mandel
