“How much do you value life? Sixty-four.”

I have no responsibility to live up to what others expect of me. That’s their mistake, not my failing.

Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.

I learned from my father to translate: everything I read I try to figure out what it really means, what it’s really saying.

You can’t say A is made of B or vice versa. All mass is interaction.

The highest forms of understanding we can achieve are laughter and human compassion.

But there is nothing in biology yet found that indicates the inevitability of death.

A philosopher once said, It is necessary for the very existence of science that the same conditions always produce the same results. Well, they don’t!

I couldn’t claim that I was smarter than sixty-five other guys-but the average of sixty-five other guys, certainly!

Science is a way of trying not to fool yourself. The principle is that you must not fool yourself, and you are the easiest person to fool.

It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.

Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it.

I’d hate to die twice. It’s so boring.

I a universe of atoms, an atom in the universe.

Nature has a great simplicity and therefore a great beauty

I don’t feel frightened by not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is, as far as I can tell. Possibly. It doesn’t frighten me.

You see, I get so much fun out of thinking that I don’t want to destroy this pleasant machine that makes life such a big kick.

God will give you what is yours and end what is not!

I’ve worked with children all my life.

Life is a movie, but there will never be a sequel.

There is no normal life that is free of pain. It’s the very wrestling with our problems that can be the impetus for our growth.

Life is never easy, but hoping for the best isn’t the solution. Wake up and make the change by yourself.

Those who educate children well are more to be honored than they who produce them; for these only gave them life, those the art of living well.

All of life is peaks and valleys. Don’t let the peaks get too high and the valleys too low.

The connections we make in the course of a life, maybe that’s what heaven is.
