This is the video of the lecture Towards the Final Laws of Physics by Steven Weinberg. Paul Dirac, one of the most important physicist s of the twentieth century, was a professor at the University of Cambridge, England. He held the chair that once ...
was occupied by Isaac Newton. When he died in 1984, his college, St John's College in Cambridge, endowed an annua l lecture to be held in Cambridge in his memory. The first of these lectures was given by Richard Feynman and Steven Weinberg. In his lecture, Weinberg shows how tightly quantum theory and relativity together constrain the laws of Nature, and he speculates now Einstein's theory of gravitation (1915) will be reconciled with quantum theory. A book accompanies this tape which contains the transparencies used in the lecture (in Weinberg's own handwriting). The print version of this lecture is available from Cambridg e University Press.
