I'm still happy with the way Einstein's Dreams came out. That book came out of a single inspiration. I really felt like I was not creating the words, that I was hearing the words. That someone else was speaking the words to me and I was just writing them down. It was a very strange experience. That can happen with a short book. I don't think it could happen with a long book.

Who would fare better in this world of fitful time? Those who have seen the future and live only one life? Or those who have not seen the future and wait to live life? Or those who deny the future and live two lives?

A world in which time is absolute is a world of consolation. For while the movements of people are unpredictable, the movement of time is predictable. While people can be doubted, time cannot be doubted. While people brood, time skips ahead without looking back.

I oppose any belief that contradicts experimental evidence as determined by the methods of science. All beliefs not in such contradiction may be considered as faith. Whether faith in a particular belief is beneficial or not is another matter.

Except for a God who sits down after the universe begins, all other gods conflict with the assumptions of science.

For my students who are trying to learn the craft of writing in a writing class - contemporary literature is what's most useful.

One cannot walk down an avenue, converse with a friend, enter a building, browse beneath the sandstone arches of an old arcade without meeting an instrument of time. Time is visible in all places. Clock towers, wristwatches, church bells divide years into months, months into days, days into hours, hours into seconds, each increment of time marching after the other in perfect succession. And beyond any particular clock, a vast scaffold of time, stretching across the universe, lays down the law of time equally for all.
