Dear Master Arora:
Your discussion of atomic forces shows that you have read entirely too much beyond your understanding. What we are talking about is real and at hand: Nature. Learn by trying to understand simple things in terms of other ideas—always honestly and directly. What keeps the clouds up, why can't I see stars in the daytime, why do colors appear on oily water, what makes the lines on the surface of water being poured from a pitcher, why does a hanging lamp swing back and forth—and all the innumerable little things you see all around you. Then when you have learned to explain simpler things, so you have learned what an explanation really is, you can then go on to more subtle questions.

Do not read so much, look about you and think of what you see there.

...

Sincerely yours,
Richard P. Feynman

Dear Sir:
The fact that I beat a drum has nothing to do with the fact that I do theoretical physics. Theoretical physics is a human endeavor, one of the higher developments of human beings—and this perpetual desire to prove that people who do it are human by showing that they do other things that a few other humans do (like playing bongo drums) is insulting to me.

I am human enough to tell you to go to hell.

Sincerely,
Richard P. Feynman
