Modern theories did not arise from revolutionary ideas which have been, so to speak, introduced into the exact sciences from without. On the contrary they have forced their way into research which was attempting consistently to carry out the programme of classical physics—they arise out of its very nature. It is for this reason that the beginnings of modern physics cannot be compared with the great upheavals of previous periods like the achievements of Copernicus. Copernicus’s idea was much more an import from outside into the concepts of the science of his time, and therefore caused far more telling changes in science than the ideas of modern physics are creating to-day.
Basic research is like shooting an arrow into the air and, where it lands, painting a target.
Mathematics is the only good metaphysics.
Interview with P. A. M. Dirac By Thomas S. Kuhn and Eugene Paul Wigner At Wigner’s home, Princeton, New Jersey April 1, l962
About Dirac I always recomend this wonderful book from Graham Farmelo: The Strangest Man: The Hidden Life of Paul Dirac, Mystic of the Atom, and alternatively, this conference by the author:
Religion is a culture of faith; science is a culture of doubt.
Artificial intelligence is the science of making machines do things that would require intelligence if done by men.
