John Bardeen and his two Nobel Prizes in Physics

On May 23, 1908, American physicist and electrical engineer John Bardeen was born. Bardeen is the only person to have won the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor;[6] and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory theory. “Science is a field which grows continuously…
