A mathematician is a device for turning coffee into theorems.

Why are numbers beautiful? It's like asking why is Beethoven's Ninth Symphony beautiful. If you don't see why, someone can't tell you. I know numbers are beautiful. If they aren't beautiful, nothing is.

Another roof, another proof.

My brain is open.

I'm not qualified to be a human being.

You don't have to believe in God, but you should believe in The Book.

Property is a nuisance.

I've been lucky to have met many good people, but I've also met many bad people. The good people are the ones who help you with your problems, and the bad people are the ones who create problems for you.

If I feel unhappy, I do mathematics to become happy. If I am happy, I do mathematics to keep happy.

A mathematician is a machine for turning coffee into theorems.

It is not enough to be a good mathematician, you must also be a good human being.

The proof is in The Book.

I want to see the proofs from The Book.

I'm not saying that God exists, but if he does, he must have a copy of The Book.

I have no time for anything but mathematics.

I am just a simple man who loves numbers.

Mathematics is the queen of the sciences and number theory is the queen of mathematics.

I don't smoke, I don't drink, I don't have a wife, I don't have children. I don't have anything but mathematics.

I'm just a number theorist, I don't know anything about the real world.

The more I learn, the more I realize how much I don't know.
