'''Paul Adrien Maurice Dirac''' (1902-1984) was a [[United Kingdom|British]] theoretical [[physicist]] who helped develop mathematical expressions of relativistic [[quantum mechanics]]. His [[science|scientific]] [[philosophy]] was this: "Physical laws should have mathematical beauty and simplicity."

Dirac developed a equation of motion for the wavefunction of the [[electron]] based on [[Theory of relativity|relativity]] (''"The importance of Dirac's work lies essentially in his famous wave equation, which introduced special relativity into Schrödinger's equation."''<ref>[http://www.nobelprize.org/nobel_prizes/physics/laureates/1933/dirac.html The Official Web Site of the Nobel Prize:] Biography of Paul Dirac</ref>.) Dirac predicted the existence of the [[positron]], the electron's [[antiparticle]], which was subsequently discovered by [[Carl Anderson]] in 1932. Dirac was awarded the Nobel Prize in 1933<ref>[http://www.nobelprize.org/nobel_prizes/physics/laureates/1933/ The Official Web Site of the Nobel Prize:] The Nobel Prize in Physics 1933

Erwin Schrödinger, Paul A.M. Dirac</ref>, the youngest scientist ever to receive this honor.  Dirac was the founder of [[quantum electrodynamics]].

Dirac published the "[[Principles of Quantum Mechanics]]" in 1930, which introduced the widely used [[Dirac delta]] [[function]] and [[bra-ket notation]].  Inspired in part by this book, the physicist [[Richard Feynman]] later proposed a path integral formulation of quantum mechanics in 1948.
