A few quanta of light leave their imprint on photographic emulsion by forming a few atoms of silver and thereby photographic reproduction is possible. This article is a discussion of the physical aspects of the latent image process.

The most penetrating cosmic rays have turned out not to be of cosmic origin at all, but the short‐lived results of cosmic ray bombardment of the atmosphere. Called mesons, these particles are suspected to be of fundamental importance in nuclear structure. In the last few years much exciting experimental work in this field has been done at the University of Bristol in England and two physicists there write about the particles of which so much is expected.

Though the language of science is international, there are differences in the approach to science between nation and nation which are a natural result of different cultures. What follows is a comparison of American with French attitudes, the result of a French scientist's two-month visit to this country. The observations first appeared in the French journal L'Atomes in November, 1947; the translation is by Louise C. Riggs.
