If an electron dropped from a high energy orbit to a lower one, it released energy as light. History of Twentieth Century Physics Paul was his father’s unwilling companion: his father forced Paul to speak French, and Paul was not allowed to leave the table if he made any mistakes in that language, which invariably he did. His father was Charles Dirac, a school teacher and private tutor who had emigrated from Switzerland to the UK. In 1928, British physicist Paul Dirac the existence of antimatter.
Quantised Singularities in the Electromagnetic Field Want it all? In 1931, the shy, brilliant British physicist Paul Dirac predicted the existence of a weird class of particles called antimatter. It is a moniker that resonates with the innumerable “Dirac stories” that abound in the mythology of the hallways of physics departments around the world.
Dirac launched QED with his 1927 paper The Quantum Theory of the Emission and Absorption of Radiation. By the beginning of December, Dirac had created an equation of great beauty and great power – the fundamental wave equation of the relativistic theory of the electron – the Dirac Equation. For years, scientists have debated the reason why our universe has more matter than antimatter. Dinosaur fossil with preserved genital orifice hints how they mated. His paper was published in September 1931.

They interact with an electron in hydrogen.
Quantum electrodynamics – often abbreviated to QED – describes the quantum interaction of light and matter. Dirac and others were perplexed by one aspect of his new equation – it produced double the expected number of electron states. His discovery was guided by the human imagination, and arcane mathematics. Have a good day
At first, Dirac did not appreciate the significance of this finding, and even ignored it out of what he would call “pure cowardice”.
In most respects—mass, for instance—particles of antimatter are identical to those of matter. Too bad Dirac is not around to shyly enjoy it. He asked himself about the quantity AB minus BA. This result may hint at a pro-matter bias built into the laws of physics. Early in 1931, Dirac produced a startling new theory. Paul Dirac was awarded the 1933 Nobel Prize in physics, together with Erwin Schrodinger, "for the discovery of new productive forms of atomic theory.".
At the time it seemed plausible: A galaxy made of antimatter would be indistinguishable from a normal one. In September 1918, aged 16, Paul Dirac began a degree course in electrical engineering at the University of Bristol.
In fact, his enigma so permeated all facets of his life that his own first name, shortened to P.A.M, was somewhat of an accidental mystery for years. These days, astronomers are quite sure that antimatter is rare in the depths of space too.
In September 1925, Fowler asked Dirac for his opinion about an unpublished paper he had received from a young physicist by the name of Werner Heisenberg. On Earth, antimatter can be created in particle accelerators, but only in minuscule quantities.
Margit had a son and daughter from her previous marriage, and Dirac became their stepfather. Heisenberg’s matrices had a property he could not account for: if you changed the order in which they were multiplied, you got a different result.
