In the history of physics, there have been three great revolutions in thought that first seemed absurd yet proved to be true. The first proposed that the earth, instead of being stationary, was moving around at a great and variable speed in a universe that is much bigger than it appears to our immediate perception. That proposal, I believe, was first made by Aristarchos two millenia ago ... Remarkably enough, the name Aristarchos in Greek means best beginning.

No endeavor that is worthwhile is simple in prospect; if it is right, it will be simple in retrospect.

It is often claimed that knowledge multiplies so rapidly that nobody can follow it. I believe this is incorrect. At least in science it is not true. The main purpose of science is simplicity and as we understand more things, everything is becoming simpler. This, of course, goes contrary to what everyone accepts.

Secrecy, once accepted, becomes an addiction.

One may say that predictions are dangerous particularly for the future. If the danger involved in a prediction is not incurred, no consequence follows and the uncertainty principle is not violated.

In the theater you create a moment, but in that moment, there is a touch, a twinkle of eternity. And not just eternity, but community. . . . That connection is a sense of life for me.

There is a time for scientists and movie stars and those who have flown the atlantic to restrain their opinions lest they be taken more seriously than they should be.
