Whether our work is art or science or the daily work of society, it is only the form in which we explore our experience which is different.

Einstein was a man who could ask immensely simple questions. And what his work showed is that when the answers are simple too, then you can hear God thinking.

It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known, but to question it.

All science is the search for unity in hidden likenesses.

There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy.

To me the most interesting thing about man is that he is an animal who practices art and science and in every known society practices both together.

But nature - that is, biological evolution - has not fitted man to any specific environment. On the contrary, ... he has a rather crude survival kit; and yet -this is the paradox of the human condition - one that fits him to all environments. Among the multitude of animals which scamper, fly, burrow and swim around us, man is the only one who is not locked into his environment. His imagination, his reason, his emotional subtlety and toughness, make it possible for him not to accept the environment but to change it.
