Polarization Optics in Telecommunicationsthe earlier ones. There is a nearly perfect correlation between what could be called the ‘paradigmatic youth’ of a specialty and the proportion of emigrant articles inthat specialty. Physicists later emigrating from Germany produced about 10.8% of the total physics literature published in Germany be

This means that of all the 1926–30 publications cited in the data base 13.8% were written or coauthored by emigrants, whereas of the cited papers published between 1931 and 1933 this is true for only 5.4%.

The ultimate answer will be different for (a) those actually involved in the field’s formation with a first-hand, although highly selective view on the progression of events,

Line Formation in a Magnetic Field,ady have noted, there is a discrepancy between the treatment of the first and the remaining intervals. Whereas the first co-citation analysis (1926–30) is based on the literature of five years of development, the other co-citation maps were each constructed on the basis of statistical analysis of th
