I am a successful lecturer in physics for popular audiences. The real entertainment gimmick is the excitement, drama and mystery of the subject matter. People love to learn something, they are 'entertained' enormously by being allowed to understand a little bit of something they never understood before. One must have faith in the subject and in people's interest in it.

We are lucky to live in an age in which we are still making discoveries.

Strange! I don't understand how it is that we can write mathematical expressions and calculate what the thing is going to do without being able to picture it.

I couldn't claim that I was smarter than sixty-five other guys--but the average of sixty-five other guys, certainly!

It appears that there are enormous differences of opinion as to the probability of a failure with loss of vehicle and of human life. The estimates range from roughly 1 in 100 to 1 in 100,000. The higher figures come from the working engineers, and the very low figures from management.

The unanswerable mysteries... the attitude that all is uncertain... to summarize it - the humility of the intellect.

We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation.
