Paul Dirac

1902-1984 · theoretical physics, quantum mechanics, quantum field theory
British theoretical physicist, one of the founders of quantum mechanics. He formulated the Dirac equation, which united special relativity and quantum theory, and predicted the existence of antimatter. His work laid the foundation for quantum electrodynamics and field theory.

Biography

Born in Bristol, England. Studied electrical engineering at the University of Bristol, then mathematics at Cambridge. Completed his doctoral thesis under Ralph Fowler. At age 30, became the Lucasian Professor of Mathematics at Cambridge (a position once held by Isaac Newton). Nobel Prize in Physics in 1933 jointly with Erwin Schrödinger. After retiring, moved to Florida, where he taught at Florida State University. Fellow of the Royal Society, member of the Order of Merit. Known for his extreme taciturnity and literal perception of the world.

Key discoveries

💡 Dirac was known for his extreme reticence. Once after a lecture a student said, 'Professor Dirac, I didn't understand the last equation.' Dirac simply remained silent. When reminded of the question, he replied, 'That was not a question, it was a statement.' He also remained unmarried for a long time, but one day met the sister of a colleague and unusually for him said, 'You are my better half.' They lived together for the rest of his life.
"He believed that the beauty of equations is more important than their agreement with experiments, and that if an equation is not beautiful, it is probably wrong."

Quantum Chip Outperforms Supercomputers: Two Hours vs. Years
The task resembles a giant maze with a single exit among billions of dead ends. A conventional computer checks each corridor step by step — taking centuries. A quantum processor launches a wave that seeps through all paths at once. The correct route echoes back, amplifying, and the answer is found in hours. That’s exactly how the “peak” circuits worked in the new experiment.

The law discovered by Wolfgang Pauli forbids identical particles from occupying the same spot. Hence, in cold matter, a Fermi sea is born: particles, like water, fill energy levels from bottom to top. The shape of the sea's surface — including 'islands' of emptiness — dictates the properties of the whole system.

At the MAMI accelerator in Mainz, researchers created the lightest hypernucleus — a triton with a lambda inside.
