Derivation of dirac equation
Web4. The Dirac Equation “A great deal more was hidden in the Dirac equation than the author had expected when he wrote it down in 1928. Dirac himself remarked in one of his talks that his equation was more intelligent than its author. It should be added, however, that it was Dirac who found most of the additional insights.” Weisskopf on Dirac Web4 Derivation of the Dirac equation We will show that the Dirac equation is the condition that the eigenfunction of a charged spin-1/2 particle inside an electromagnetic potential ( A μ ) must satisfy in order to fulfill the
