Standing beneath the white light of an Apple store is like standing on a Stanley Kubrick movie set. His '2001: A Space Odyssey' predicted Jobs and a future where technology was our friend. Kubrick of course didn't like what he saw. And occasionally I have my doubts.

A civilized society is one which tolerates eccentricity to the point of doubtful sanity.

No doubt it is true that science cannot study God but it hardly follows that God had to keep a safe distance from everything that scientists want to study.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television and without any doubt it was a big contributor to my passions for science engineering and exploration.

True science teaches above all to doubt and to be ignorant.

The capacity of the female mind for studies of the highest order cannot be doubted having been sufficiently illustrated by its works of genius of erudition and of science.
