“I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way—by rote, or something. Their knowledge is so fragile!”

I would rather have questions that can’t be answered than answers that can’t be questioned.

That was a very good way to get educated, working on the senior problems and learning how to pronounce things.

If I could explain it to the average person, I wouldn’t have been worth the Nobel Prize.

Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning.

I was an ordinary person who studied hard. There are no miracle people. It happens they get interested in this thing and they learn all this stuff, but they’re just people.

Physics is to math what sex is to masturbation.

How much do you value life? Sixty-four.

The game I play is a very interesting one. It’s imagination, in a tight straightjacket.

All mass is interaction.

Thank you very Much, I enjoyed myself.

I’m smart enough to know that I’m dumb.

Science is the belief in the ignorance of experts.

Words can be meaningless. If they are used in such a way that no sharp conclusions can be drawn.

Tell your son to stop trying to fill your head with science — for to fill your heart with love is enough.

I can live with doubt and uncertainty and not knowing. I think it’s much more interesting to live not knowing than to have answers that might be wrong.

The individual member of the social community often receives his information via visual, symbolic channels. I went back and forth over it, and translated. You know what it means? People read.

Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.

There is, however, another purpose to which academies contribute. When they consist of a limited number of persons, eminent for their knowledge, it becomes an object of ambition to be admitted on their list.

The saddest thing in life and the hardest to live through, is the knowledge that there is someone you love very much whom you cannot save from suffering.

The end of all learning is to know God, and out of that knowledge to love and imitate Him.

Failure is predictable if you break laws, success is predictable if you obey laws. I discovered and learned that truth when I was 14 years old. Not everyone discovers that. Some people take a lifetime to learn that.

Whatever Nature has in store for mankind, unpleasant as it may be, men must accept, for ignorance is never better than knowledge.

The first steps in the path of discovery, and the first approximate measures, are those which add most to the existing knowledge of mankind.

A little knowledge is a dangerous thing – it only hastens fools to rush in where angels fear to tread.
