British theoretical physicist Paul Dirac is known within astronomy primarily for the hypothesis that certain ratios of fundamental constants (called “large numbers” because some of them are on the order of 1040) should not change as the Universe expands. Raised in Bristol by an English mother and Swiss father, Dirac was recognized as being bright at an early age. He obtained an engineering degree in 1921 and a mathematics degree in 1923, both from Bristol, then moved to Cambridge to pursue research. Dirac was awarded a Ph.D. in 1926 for work on quantum mechanics with 11 papers already published. He produced the Dirac equation in 1928 and his text The Principles of Quantum Mechanicsin 1930. He was made Lucasian Professor of Mathematics at Cambridge University in 1932, and remained in that position until 1969, when he moved to Florida State University. Dirac received the Nobel Prize in Physics in 1933 for...
