The test confirmed an underlying theory of quantum mechanics — namely, that a measurement made on one photon has an instantaneous effect on the nature of another photon.
When I was a graduate student in physical chemistry at Yale, I had the remarkable experience of taking a course in relativistic quantum mechanics from Nobel laureate Willis Lamb.
My intellectual life was immersed in quantum mechanics and second-order differential equations, and my heroes were the giants of physics—Albert Einstein, Niels Bohr, Werner Heisenberg, and Paul Dirac.
