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.

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

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.

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.'
