I write for the same reason I breathe - because if I didn't, I would die.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I found it!) but 'That's funny ...'

It pays to be obvious, especially if you have a reputation for subtlety.

I do not fear computers. I fear the lack of them.

Never let your sense of morals get in the way of doing what's right.

You must keep sending work out; you must never let a manuscript do nothing but eat its head off in a drawer. You send that work out again and again, while you're working on another one. If you have talent, you will receive some measure of success - but only if you persist.

Violence is the last refuge of the incompetent.

No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be. . ..

Science can be introduced to children well or poorly. If poorly, children can be turned away from science; they can develop a lifelong antipathy; they will be in a far worse condition than if they had never been introduced to science at all.

The most exciting phrase to hear in science, the one that heralds the most discoveries, is not 'Eureka!' (I found it!) but 'That's funny...'

The three fundamental Rules of Robotics...One: a robot may not injure a human being, or, through inaction, allow a human being to come to harm...Two:..a robot must obey the orders given it by human beings except where such orders would conflict with the First Law...Three: a robot must protect its own existence as long as such protection does not conflict with the First and Second Laws.

Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest.

One, a robot may not injure a human being, or through inaction, allow a human being to come to harm;
Two, a robot must obey the orders given it by human beings except where such orders would conflict with the First Law; Three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

If knowledge can create problems, it is not through ignorance that we can solve them.

To surrender to ignorance and call it God has always been premature, and it remains premature today.

Life is pleasant. Death is peaceful. It's the transition that's troublesome.

The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.

Why is it that you physicists always require so much expensive equipment? Now the Department of Mathematics requires nothing but money for paper, pencils, and erasers...and the Department of Philosophy is better still. It doesn't even ask for erasers.

I do not fear computers. I fear lack of them.

People who think they know everything are a great annoyance to those of us who do.

So the universe is not quite as you thought it was. Youd better rearrange your beliefs, then. Because you certainly cant rearrange the universe.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not -Eureka!- but -That's funny...-.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
