Casimir effect

In 1947 Hendrik Casimir, once an assistant of Pauli, was working in applied industrial research at the Philips Laboratory in the Netherlands along with physicist J. T. G. Overbeek. They were analyzing the theory of van der Waals forces when Casimir had the opportunity to discuss ideas with Niels Bohr on a walk. According to Casimir, Bohr ''mumbled something about zero-point energy'' being relevant. This led Casimir to an analysis of zero-point energy effects in the related problem of forces between perfectly conducting parallel plates.
