This caused Friedberg some embarrassment later when classmates at Harvard, knowing of the result only through Jammerâs book, supposed that Friedberg was the first discoverer. (A letter from Friedberg to Jammer dated May 1971 begins, âIt was nice of you to remember what I showed you in 1968. I finally got around to writing it up in 1969, but just then I found out about Bellâs 1964 paper (Physics 1, 195) which had anticipated my âdiscoveryâ by three years. So I did not publish.â) More recently, Friedberg worked on the foundations of quantum mechanics in collaboration with the late

Friedberg wrote an informal book on number theory titled "An
Adventurer's Guide to Number Theory". In the book, he states, "The difference between the theory of numbers and arithmetic is like the difference between poetry and grammar."

Friedberg's most well-known work dates back to the mid-1950s. As an undergraduate at
Harvard, he published several papers over a period of 2â3 years. The first paper introduced the priority method, a common technique in
