For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss.

Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

No! Not for a second! I immediately began to think how this could have happened. And I realized that the clock was old and was always breaking. That the clock probably stopped some time before and the nurse coming in to the room to record the time of death would have looked at the clock and jotted down the time from that. I never made any supernatural connection, not even for a second. I just wanted to figure out how it happened.

If all of mathematics disappeared, physics would be set back by exactly one week.
