[PAR] [TLE] Paul Dirac [SEP] Paul Adrien Maurice Dirac {'1': ", '2': ", '3': ", '4': "} ( ; 8 August 1902 – 20 October 1984) was an English theoretical physicist who made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics.  He was the Lucasian Professor of Mathematics at the University of Cambridge, a member of the Center for Theoretical Studies, University of Miami, and spent the last decade of his life at Florida State University. [PAR] [TLE] Dirac hole theory [SEP] Dirac hole theory is a theory in quantum mechanics, named after English theoretical physicist Paul Dirac.  The theory poses that the continuum of negative energy states, that are solutions to the Dirac equation, are filled with electrons, and the vacancies in this continuum (holes) are manifested as positrons with energy and momentum that are the negative of those of the state.  The discovery of the positron in 1929 gave a considerable support to the Dirac hole theory.
