The most beautiful experience we can have is the mysterious. It is the source of all true art and science.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.

The man of science is a poor philosopher.

Science without religion is lame. Religion without science is blind.

Science is the century-old endeavour to bring together... perceptible phenomena... through systematic thought.

Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.
