 Weinberg entered the University of Chicago , from which he received his Bachelor of Science ( B.S. ) degree in Physics in 1935 , and his Master of Science ( M.S. ) in Physics the following year . He received his Ph.D. from the University of Chicago in mathematical biophysics in 1939 , writing his thesis on Mathematical foundations for a theory of biophysical periodicity , under the supervision of Carl Eckart . Weinberg later lamented that , in restricting his thesis to linear systems , he had overlooked interesting nonlinear systems that Ilya Prigogine later received the Nobel Prize in Chemistry for studying .
