Dirac equation
The Dirac equation gives a mathematical description of all spin-½ massive particles.
Explanation
The equation was originally written in the form
where
β 4×4 matrix m Mass c Speed of light an 4×4 matrix pn Momentum operator 4×4 matrix ψ Wave function x,t Spacetime coordinates i Imaginary unit ℏ Reduced Planck constant Partial derivative with respect to time
HistoryThe British physicist Paul Dirac published the equation in 1928. It was the first theory to account fully for special relativity in the context of quantum mechanics. |
