Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933. Now it is our turn to study statistical mechanics. Perhaps it will be wise to approach the subject cautiously.

The raw material for... both the television programs and the textbooks... was a set of verbatim transcripts of the lectures delivered by Goldstein in the revised Caltech physics course. ...[T]he material would be would be presented at two levels, at least in the textbooks if not in the television programs. The upper level... for physics and engineering majors... [t]he other textbook, which corresponds to the level of the television programs... for a more general audience. Nevertheless, it... include[d] differential and integral calculus... presented as they had arisen historically... as part of... mechanics. Mastering... simple... s and s would make physics easier to understand than... the pseudocalculus... in many college physics courses. ...Liberal Arts students had little difficulty learning calculus. ...[T]his was a "major pedagogic triumph" ...A primer, written by Apostol ...was added to the ...arsenal of aids ...

So I went to Murph... and he said, "I’ll give you a little money to look into it." ...I think $50,000—and I hired... Don Delson... head of AV... to be my assistant... We learned all kinds of things...
