Books

The Experimental Foundations of Particle Physics, by Robert N. Cahn and Gerson Goldhaber of Berkeley, published by Cambridge University Press, uses reprints of some sixty classic papers to illustrate the ad• vances of the past fifty years. Grouped into chapters with an ac• companying introductory text, the papers make for informative read• ing by specialist and beginner alike.

Hans Dehmelt of Wahsington, who shared the 1989 Nobel Physics Prize with Norman Ramsey and with Wolfgang Paul (December 1989, page 23), visited CERN in December, where he gave a talk on 'Experiments with an isolated at rest.
