Mathematics is the foundation upon which all science is built.

The great thing is to be in love with life.

"You have to put in the hours because there’s always something which you can improve."

"Don't be afraid to give up the good to go for the great."

People haven't always been there for me, but music always has.

Every great advance in science has issued from a new audacity of imagination.

当你处于困境时，记住你为什么要开始。
