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

Science progresses not by convincing the adherents of old theories that they are wrong, but by allowing enough time to pass so that a new generation can arise unencumbered by the old errors.

There is a real world independent of our senses; the laws of nature were not invented by man, but forced on him by the natural world. They are the expression of a natural world order.

Religion and natural science are fighting a joint battle in an incessant, never-relaxing crusade against skepticism and dogmatism, against disbelief and against superstition, and the rallying cry in this crusade has always been, and will always be, 'On to God.'

Scientific discovery and scientific knowledge have been achieved only by those who have gone in pursuit of it without any practical purpose whatsoever in view.

Modern physics has taught us that the nature of any system cannot be discovered by dividing it into its component parts and studying each part by itself... We must keep our attention fixed on the whole and on the interconnection between the parts. The same is true of our intellectual life. It is impossible to make a clear cut between science, religion, and art. The whole is never equal simply to the sum of its various parts.

We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future.
