Three Lectures by Hans Bethe

Theoretical physicist Hans Albrecht Bethe passed away last year, at the age of 98. In his career, he won the 1967 Nobel Prize in Physics for his work on the theory of stellar nucleosynthesis; and was the head of the Theoretical Division of the Los Alamos Laboratory during WWII, playing a key role in developing the nuclear bombs of the Trinity test and "Fat Man" weapon. He later went on to campaign against nuclear testing and the arms race.

In 1999, he delivered three lectures on quantum theory to his neighbours at the Kendal of Ithaca retirement community. The lectures are available online with accompanying slides.
