From a long view of the history of mankind the most significant event of the nineteenth century will be judged as Maxwell's discovery of the laws of electrodynamics.

I'd hate to die twice. It's so boring.

It is our responsibility as scientists, knowing the great progress which comes from a satisfactory philosophy of ignorance, the great progress which is the fruit of freedom of thought, to proclaim the value of this freedom; to teach how doubt is not to be feared but welcomed and discussed; and to demand this freedom as our duty to all coming generations.

To decide upon the answer is not scientific. In order to make progress, one must leave the door to the unknown ajar ajar only.

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.

It is not unscientific to make a guess, although many people who are not in science think it is.

To develop working ideas efficiently, I try to fail as fast as I can.
