Summary

Publication week! Say hello to Quanta and Fields, the second volume of the planned three-volume series The Biggest Ideas in the Universe. This volume covers quantum physics generally, but focuses especially on the wonders of quantum field theory. To celebrate, this solo podcast talks about some of the big ideas that make QFT so compelling: how quantized fields produce particles, how gauge symmetries lead to forces of nature, and how those forces can manifest in different phases, including Higgs and confinement.

How do I know?

Hello everyone, welcome to the Mindscape Podcast. I'm your host Sean Carroll and we're very excited these days

0:36.2

Here at Mindscape World International Headquarters for Book Publication Week as some of you know, on Tuesday, I guess May 14th, here in the United States anyway,

0:47.2

we're going to have the publication of Quanta and Fields. This is volume two in the biggest ideas in the universe series.

0:55.0

The series will be a three-part series that aims to explain modern physics, the part of modern physics that we know, not the speculative stuff, we're not going to

1:04.4

be talking about the multiverse or quantum gravity or anything like that, the kinds that ideas in

1:09.5

modern physics that we think will last for a very very long time and the gimmick is we're explaining them in a way

1:17.3

that involves the equations so we're gonna show you the equations and that means it's not for everybody but it's very much

1:24.5

for some people if you've ever read descriptions of physics where you thought that

1:28.8

there was something going on but there's a bunch of metaphors and stories and analogies and you weren't quite sure

1:35.2

why things were working out the way they were working out.

1:38.0

These are the books for you.

1:40.0

And the biggest ideas you'll really get to see why, for example, the Higgs mechanism gives

1:46.6

mass to particles and things like that.

1:50.0

You don't need to just wave your hands in any way.

1:52.8

And the general theme of the book is Quanta and Fields.
