He later became a science writer there, which continued until his retirement. His prolific writings also included critical reviews, obituaries of scientists, encyclopedia entries and four science books. At the Lowell Institute, he gave a notable series of lectures in 1935. As a speaker, he could interpret physics with clarity whether to a gathering of scientist or to wider intellectual audiences in other communities. Four universities at different times between 1929 and 1942 invited him as a visiting professor.
