My teacher M. A. Leontovich

My teacher, the person who taught me the profession of scientist, was Mikhail Alexandrovich Leontovich. His teacher was Leonid Isaakovich Mandelstam. When studying at the Moscow University, I attended his physical seminar several times. Usually, “entire physical Moscow” met there. For the students this seminar was quite complicated. In fact, I understood very little from the reports, but resuming words of L.I. were, as a rule, understandable. Now I know that if the speaker understands what he made, then he can explain the essence of his work in a form clear to “almost anyone”. The technique can be complicated but the logic is always simple.
