I was in love with a beautiful blonde once, dear. She drove me to drink. That's the one thing I'm so indebted to her for.

William Draper HarkinsBorn 28 Dec 1873; died 7 Mar 1951 at age 77.American nuclear chemist who was one of the first to investigate the structure and fusion reactions of the nucleus. In 1920, Harkins predicted the existence of the neutron, subsequently discovered by Edwin Chadwick's experiment. He made pioneering studies of nuclear reactions with Wilson cloud chambers. In the early 1930's, (with M.D. Kamen) he built a cyclotron. Harkins demonstrated that in neutron bombardment reactions the first step in neutron capture is the formation of an “excited nucleus”of measurable lifetime, which subsequently splits into fragments. He also suggested that subatomic energy might provide enough energy to power the Sun over its lifetime.« |
