“Experiment is the only means of knowledge at our disposal. Everything else is poetry, imagination.”

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

“Science…means unresting endeavor and continually progressing development toward an aim which the poetic intuition may apprehend, but the intellect can never fully grasp.”

“A new 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.”

“Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.”

“Science advances one funeral at a time.”

“The assumption of an absolute determinism is the essential foundation of every scientific enquiry.”
