![Paul Dirac
Paul Adrien Maurice Dirac was born on 8th August, 1902, at Bristol, England.
"Dirac's work was concerned with the mathematical and theoretical aspects of quantum mechanics.
He began work on the new quantum mechanics as soon as it was introduced by Heisenberg in 1925 - independently producing a mathematical equivalent which consisted essentially of a noncommutative algebra for calculating atomic properties - and wrote a series of papers on the subject, published mainly in the Proceedings of the Royal Society, leading up to his relativistic theory of the electron (1928) and the theory of holes (1930). This latter theory required the existence of a positive particle having the same mass and charge as the known (negative) electron. This, the positron was discovered experimentally at a later date (1932) by C. D. Anderson, while its existence was likewise proved by Blackett and Occhialini (1933 ) in the phenomena of "pair production" and "annihilation".
In early 20th century Paul Dirac, came up with an equation that had a negative energy solution that was simply ignored.
