Articles
Physics and social change
Physics Today 24 (10), 23–27 (1971);
https://doi.org/10.1063/1.3022381
Our science grows by correcting faulty theories, not by idolizing them. Society, in the same way, should see its present customs as jumping‐off points, not as fixed institutions.
Origins of cosmic rays
Physics Today 24 (10), 30–38 (1971);
https://doi.org/10.1063/1.3022382
Each new means of detection shows cosmic rays to be more complex than we had thought, so that more and more bravery is demanded of astrophysicists who propose sources for these rays.
A parting look at the National Register
Physics Today 24 (10), 40–46 (1971);
https://doi.org/10.1063/1.3022383
Data for 1970, the final year for this catalog of US science manpower, show physics doing better than some other sciences, with some kinds of physicists doing better than others.
