Bruria Kaufman


Bruria Kaufman was an American theoretical physicist. She is known for contributions to Albert Einstein's general theory of relativity, to statistical physics, where she used applied spinor analysis to rederive the result of Lars Onsager on the partition function of the two-dimensional Ising model, and to the study of the Mössbauer effect, on which she collaborated with John von Neumann and Harry Lipkin.
