How to pronounce “dirac” in English

Dirac had already seen it done by Werner Heisenberg, his new, if unlikely, friend.

Dirac and Heisenberg were very different characters.

- Dirac recognized something similar in his coefficients where the order of multiplication clearly mattered.

Dirac is one of the smartest people of the 20th century in physics, right?

Dirac had found coefficients that worked.

- Dirac admitted himself that he had never set out to capture spin in his equation.

- Dirac spent three years sticking to his guns.

- Dirac is probably less well-known than people like Heisenberg or Schrödinger, but his contribution to quantum physics was immense, and he was recognized for it.

Dirac, his prediction only took five years for it to be experimentally confirmed.

Dirac, who invented the electron positron idea, and all that.

- Paul Dirac seemed to have favored this approach.

And Dirac, for the whole meal, which lasted three hours, didn't say a single word.

To Dirac, this got to the core of what a good theory must do.

As Dirac put it, that, of course, is physically nonsense.

in Dirac's case, you actually need a wave function that has four components.

- When Dirac said that, people didn't start running around saying, "Where's this antielectron?"

But Dirac really was, you know, out there.

and Dirac for founding it.

Paul Dirac, like Einstein, through the mathematics, arrives at a puzzling insight into the nature of universe,

Because after Dirac united special relativity with quantum mechanics, all following quantum theories also incorporated special relativity.

He was Paul Dirac, a man who Bohr would later give the nickname The Strangest Man because he was truly one of a kind.

- Do you know why Dirac was so drawn to relativity?

But with Dirac's four-component solution, the top two wave functions now described two different spin states with two slightly different energies.

It was Dirac's beautiful equation that Heisenberg called, "The saddest chapter in modern physics."

Just one year after Dirac proposed the antielectron, Carl Anderson found it entirely by accident.

lectures of Paul Dirac taking antimatter seriously.

So after Dirac's prediction, viewed as one of the greatest predictions of all time, curiosity didn't stop there.

this form of Dirac statistics.

That made a huge impression on Dirac, right?

- He theorized something called the Dirac sea, describing a vacuum as an infinite sea of electrons occupying all available negative energy states.

actually became a reasonable friend of Dirac's.

Einstein was less lucky than Dirac.

But the amazing thing that Dirac arrived at was that the point-like particles of matter

It's exactly what that minus sign in Dirac's equation was revealing.

- Dirac was a man of so few words that his colleagues invented a special unit, a Dirac, equivalent to speaking one word per hour.

As a student, Dirac had attended seminars on Einstein's theory of relativity, and he'd kind of fallen in love with it.

- So, Dirac found a new hobby, obsessively updating classical equations with Einstein's theory of relativity, so that they would now work

So, Dirac did what Dirac does best, and he set out to find his own solution that contained no second-order time derivatives.

So Dirac now had a set of simultaneous equations for alpha x, alpha y, alpha z, and beta that he just needed to solve.

So, Dirac asked him, "Why do you dance?" Dirac thought about this for a bit before saying,

- As a PhD student, Dirac had closely followed Heisenberg's work, and a few years earlier, Heisenberg had founded for certain properties,

- Then, Dirac had a stroke of genius.

- The four-component wave function means that the Dirac equation describes four possible states for any quantum system, which reveals something

Because that strange man presenting his work was actually Paul Dirac sharing his new equation with the world.

So, Dirac was proposing that those four states described in his four-component wave function are a spin up electron, a spin down electron,

Fortunately, Dirac proposed a solution to this problem as well, although it was a little crazy.

Of course, it's Dirac we're talking about, but if you feel like it's hard to come to terms with the idea that we're floating

corresponding to particles, and Dirac got that through this crazy model.

And in 1934, introduced Dirac to his sister, Margit Wigner, a woman who would change Dirac's life, perhaps more than any equation or Nobel Prize.
