The successful user of mathematics is practically an inventor of new ways of obtaining answers in given situations

Math may permit wildly different apparent starting points.

You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no real problem.

We're so used to circumstances in which these electrical phenomena are all canceled out, everything is sort of neutral, where pushing and pulling is sort of dull, but nature has these wonderful things: magnetic forces and electrical forces.

My father left me his words. From them I remember both his outlook on life and his voice, positive, and clear. He was someone who didn't worry about small problems. His advice here—leave it; let it go— is inspiring.

The road to hell is paved with leeks and potatoes.

Agnostic for me would be trying to weasel out and sound a little nicer than I am about this.

Astronomy is older than physics. In fact, it got physics started by showing the beautiful simplicity of the motion of the stars and planets, the understanding of which was the beginning of physics. But the most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.
