Scientific work will never stop, and it would be terrible if it did. If there were no more problems, you would put your hands in your pockets and your head on a pillow and would work no more. In science rest is stagnation, rest is death.

There can never be any real opposition between religion and science; for the one is the complement of the other. Every serious and reflective person realizes, I think, that the religious element in his nature must be recognized and cultivated if all the powers of the human soul are to act together in perfect balance and harmony. And indeed it was not by accident that the greatest thinkers of all ages were deeply religious souls

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.

Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'Ye must have faith.'

A scientist is happy, not in resting on his attainments but in the steady acquisition of fresh knowledge.

An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.
