A new truth always has to conend with many difficulties. If it were not so, it would have been discovered much sooner.

Science advances one funeral at a time.

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

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.'

There is no matter as such—mind is the matrix of all matter.

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

Every advance in knowledge brings us face to face with the mystery of our own being.
