I mentioned my results to Niels Bohr, during a walk. That is nice, he said. That is something new. I told him that I was puzzeld by the extremely simple form of the expressions for the interaction at very large distances and he mumbled something about zero-ponit energy. That was all, but it put me on a new track. H. B. G. Casimir (March 1992) Hendrik Brugt Gerhard Casimir (1909-2000)
