“Of course, you only live one life, and you make all your mistakes, and learn what not to do, and that’s the end of you.”

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.

To every man is given the key to the gates of heaven. The same key opens the gates of hell.

I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way—by rote, or something. Their knowledge is so fragile!

We are lucky to live in an age in which we are still making discoveries.

I breathe him in so deep that when he is gone I exhale and taste him again.

Heard you told him that you’d love him ’til the end of time. Now that’s the same thing that you told me.

Now a soft kiss – Aye, by that kiss, I vow an endless bliss.

In my adult life I’ve understood that if I put an enormous amount of love and honesty into something, usually that shows in the end.

A lot of people run a race to see who is fastest. I run to see who has the most guts, who can punish himself into exhausting pace, and then at the end, punish himself even more.
