Maybe it was a general.

It was always the uniform, the position.

This man has the same human problems.

He eats dinner like anybody else.

He goes to the bathroom.

He's a human being.

Why are they all bowing to him?

Only because of his name and his position, because of his uniform, not because of something he especially did.

He, by the way, was in the uniform business, so he knew what the difference was with a man with the uniform off and the uniform on.

It's the same man for him.

No grades.

What was it?

It was Feynman standing in front of the blackboard saying, ask me anything.

You ask me if an ordinary person, by studying hard, would get to be able to imagine these things like I imagine.

Of course, I was an ordinary person who studied hard.

There's no talent, a special miracle ability to understand quantum mechanics or a miracle ability to imagine electromagnetic fields that comes

without practice and reading and learning and study.

You take an ordinary person who's willing to devote a great deal of time and study and work and thinking and mathematics, then he's become a scientist.

The physicist John Preskill.

Feynman officially taught an undergraduate class at Caltech only for two years.
