Issues

It is sometimes forgotten that physics remains physics even when it is applied. The present article has been written by a physicist who has to wrestle with the physical problems besetting watchmakers in their effort to mass produce ever smaller and more accurate time pieces.

In the September issue of Physics Today the authors of the present article summarized the activities of some 1700 physicists who received their PhD's in the period between 1936 and 1948, showing where they work and what they do. This article, an extension of the same ONR‐sponsored study, shows where these physicists were born and where they received their doctorates. Many of the basic data reported here were collected by M. H. Trytten, director of the National Research Council's Office of Scientific Personnel.
