that violates quantum theory. Quantum theory believes in probabilities.

Right after quantum theory was formulated, people began wondering whether it could explain thermodynamic phenomena.

And then he took quantum theory of electromagnetism.

And that's a quantum theory.

And we use quantum theory generally for atoms.

Start with some quantum theory and finding gravity within it.

String theory is a quantum theory.

His thought experiment revealed that quantum theory is non-local.

But when you get to quantum theory and all the crazy things, particles losing their identity

I am abusing what I know about quantum theory to do a problem that should be done classically.

So if you have a quantum theory-- if you develop quantum mechanics in that superconductor-- you'll describe electromagnetism as a short-range force.

It's also a misunderstanding that quantum theory is indeterminate.

And then this came along-- quantum theory.

All of it is a benefit from the quantum theory.

Werner Heisenberg was a German physicist who helped found quantum theory during the 1920s.

as a result of all the research into quantum theory that you're doing?

But if you take a good class in quantum theory and try to understand the quantum model for real, that's not so simple, not at all.

It is not the kind of theory that's a quantum theory.

But yeah, the quantum theory does make possible the fact that you might be able to build a time machine if you

There is no need or way to come up with a quantum theory of measurement.

energies or enormously small distances at which the quantum theory of

It was taken at the 1927 Solvay Conference where the architects of the brand new quantum theory gathered to discuss it.

and in this case, the mathematics of quantum theory can describe the universe or could describe a person.

And he was actually much more worried about it than almost any other aspect of quantum theory.

So it's kind of spooky, this breakthrough that starts the ball rolling toward quantum theory brings action in not energy

I was wondering if you could elaborate a bit more on the significance of each of these concepts in the context of quantum theory,

And that had to do-- so in Hawking radiation, what he did was he applied quantum theory to black holes for the first time, which people--

And Niels Bohr one said, "those who are not shocked when they first come across quantum theory cannot possibly have understood it."

Physicists have gotten to the point where they no longer want to ask the big questions about quantum theory.

In fact, Niels Bohr himself said that coming up with a quantum theory of measurement was fundamentally misguided as a scientific project.

And the reason we do that is because general relativity is a classical theory, not a quantum theory.

And yet, those very same brains have the emergent property that they can understand quantum theory.

You see, the problem is when we want to-- when we want to-- string theorists claim to be a particular candidate for a quantum theory of gravity.

His contributions to the field of physics include more than 200 scientific articles, as well as two monographs on loop quantum theory.

He's here today to discuss his latest book, "Helgoland," which explores the fundamental principles, challenges, and mysteries of quantum theory, tracing its genesis back

I have colleagues, in fact, that do not like this relational reading of quantum theory.

And, in fact, there are other attempts to make sense of quantum theory.

I think physics, as you're taking your first physics courses, it really starts to get exciting when you go into quantum theory and the really weird aspects

And everywhere along the way, until the mid 1920s where we really-- where physics really got to a theory, a quantum theory that was pretty well developed, people kept saying,

And until then, people had, including Stephen, had treated black holes just using general relativity without trying to see if quantum theory implied

And then his work in, it was, I think, 1981 or '83 on applying quantum theory now

And as you go back in time, what happens is time, because of general relativity and the interplay of quantum theory, it starts to lose its character.

So you start with some classical stuff, and then there's rules that you're taught in graduate school or undergraduate education for turning that into a good quantum theory.

In other words, don't quantize gravity in the sense of starting with some classical model and turning it into a quantum theory.

There were some things, especially like the section you just read, which there's a lot of quantum theory there, which Neal's a little more comfortable than I am.

And so this picture-- this is a complete picture of the quantum theory of electromagnetism.

And people talk a lot about God not playing dice with the universe and Einstein was very worried about the indeterminism or randomness of quantum theory.

and to get a mate, and rear a child, and avoid being eaten by lions, fairly simple problems compared to quantum theory or relativity.

I love going to the ones on, you know, quantum theory and quantum gravity.
