How good at math was Paul Dirac

Antimatter

presentation
Antimatter is nothing mysterious. More precisely, it was once something mysterious, but only for 4 or 5 years. After Einstein set up his theory of relativity and the quantum physicists set up quantum mechanics, there were attempts to unite these two theories, one in the area of ​​the macrocosm and the other in the area of ​​the microcosm. The first success came from Paul Dirac. Dirac is an English physicist and an incredibly brilliant mathematician. Dirac completed a theory in 1928 that ties together quantum physics and the special theory of relativity and that has retained its validity to this day (despite many discoveries that came afterwards). Dirac noted in his new theory that there are solutions that do not appear physically sensible at first glance. To clarify this fact, let's make a comparison with a very simple task: A square railing has an area of ​​4 km 2, how big is the side length? The student says 2km. Well, the meticulous mathematician would say plus minus 2km. But obviously there is no physical sense for the -2km, so take the 2km as the solution. The same thing happened to Dirac. Now Dirac was one of those people who trust mathematics very much. If mathematics delivers such a solution, then it must also have a meaning in nature, he said to himself. And so he saw ...
