Paul Dirac

Who he was

Paul Dirac (1902–1984) was an English theoretical physicist, one of the founders of quantum mechanics and quantum electrodynamics. His 1928 relativistic wave equation for the electron unified quantum mechanics with special relativity, and correctly predicted the existence of antimatter (the positron, discovered in 1932) before it was observed. He shared the 1933 Nobel Prize in Physics with Erwin Schrödinger.

What he’s known for on this site

Dirac’s 1928 equation predicts exactly $g=2$ for the electron’s magnetic moment, the tree-level starting point that Julian Schwinger’s 1948 QED correction refines — see QED Anomalous Magnetic Moment. The correctly-quantized Dirac Lagrangian for a spin-1/2 fermion field also appears as the real, standard component of Aether-Spin-Entanglement Coupling, the formula PBT builds its own additions on top of.

Catalog status: Proven Systems

The Dirac equation is core, exhaustively confirmed relativistic quantum mechanics — among the most successful theoretical predictions in the history of physics, given its correct prediction of antimatter.

Where this touches PBT

PBT’s own spin-entanglement formula uses the real Dirac Lagrangian as its verified starting term, then adds its own unproven coupling terms on top — the Dirac component itself is not in question, only what PBT adds beyond it.
