## Who solved the Dirac equation?

physicist Paul Dirac

In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1⁄2 massive particles such as electrons and quarks for which parity is a symmetry.

## What is the difference between Klein-Gordon and Dirac equation?

The Klein-Gordon field gives a spin 0 representation, while the Dirac equation gives two spin 1/2 representations (which merge to a single representation if one also accounts for discrete symmetries). The components of every free field satistfy the Klein-Gordon equation, irrespective of their spin.

**How did Dirac find his equation?**

Much later, when someone asked him (as many must have done before) “How did you find the Dirac equation?” he is said to have replied: “I found it beautiful.” Second, it agreed with precise measurements of the energies of light emitted from atoms, in particularly where these differed from ordinary (non-relativistic) …

### Why does the Klein-Gordon equation fail?

Any solution of the free Dirac equation is, for each of its four components, a solution of the free Klein–Gordon equation. The Klein–Gordon equation does not form the basis of a consistent quantum relativistic one-particle theory. There is no known such theory for particles of any spin.

### What was the final prediction of the Dirac equation?

Eventually he realised that his equation predicted something entirely new to science – antiparticles. He went on to assert that every particle has a mirror-image antiparticle with nearly identical properties, except for an opposite electric charge.

**How did Paul Dirac predict antimatter?**

In 1928, Paul Dirac postulated the existence of positively charged electrons. The result was an equation describing both matter and antimatter in terms of quantum fields. This work was a truly historic triumph, because it was experimentally confirmed and it inaugurated a new way of thinking about particles and fields.

#### How did Dirac predict antimatter?

#### What type of particles obey Klein-Gordon equation?

An equation obeying the laws of special relativity is the Klein-Gordon equation, KGE, which describes spin-0 particles with relativistic energy. Such a particle is the pi meson, the pion. A pion is a short lived subatomic particle that can take the place of an electron in an atom creating a pionic atom [1].

**Is Klein-Gordon equation wrong?**

Of course the correct energy levels (or more precisely: the differences between energy levels) were known with high precision long before the theories, from experimental spectroscopy of the hydrogen spectrum. So it turned out, that the Klein-Gordon results are wrong, and the Dirac results are correct.

## Who first predicted antimatter?

Paul Dirac

Paul Dirac was trying to reconcile relativity with quantum mechanics and ended up predicting the existence of antimatter. In the first quarter of the 20th century, it was an intense time to be a physicist.

## Which physicist won a Nobel Prize for solving the Dirac equation?

The Nobel Prize in Physics 1933 was awarded jointly to Erwin Schrödinger and Paul Adrien Maurice Dirac “for the discovery of new productive forms of atomic theory.”

**Is antimatter real or theoretical?**

Although it may sound like something out of science fiction, antimatter is real. Antimatter was created along with matter after the Big Bang. But antimatter is rare in today’s universe, and scientists aren’t sure why.

### Is dark matter antimatter?

We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them. Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter.
