Leonard Susskind, Art Friedman - Special Relativity and Classical Field Theo

We will refer to it from time to time simply as Volume I. The second book Volume II explains quantum mechanics and its relationship to classical mechanics. This third volume covers special relativity and classical field theory. This book is one of several that closely follow my Internet course series, The Theoretical Minimum. My coauthor, Art Friedman, was a student in these courses. The book benefited from the fact that Art was learning the subject and was therefore sensitive to the issues that might be confusing to the beginner.

The two previous books in this series cover classical mechanics and basic quantum mechanics. Classical field theory means electromagnetic theory—waves, forces on charged particles, and so on—in the context of SR. Leonard Susskind My parents, the children of immigrants, were bilingual. They taught us kids some Yiddish words and phrases but mainly reserved that language for themselves, often to say things they did not want us to understand. Many of their secret conversations were accompanied by loud peals of laughter.

It bothers me that my own comprehension is so limited. A lot of us have similar feelings about mathematical physics. We want to understand the great ideas and problems and engage our own creativity. In this series, our goal is to teach you the language of physics and show you some of the great ideas in their native habitat.

Working with the professionals at Brockman, Inc. John Brockman, Max Brockman, and Michael Healey played a critical role in transforming our idea into a real project. Laura Stickney of Penguin Books coordinated the publication of the UK edition so smoothly, we hardly saw it happening. Copyeditor Amy J. Schneider made substantial improvements to our initial manuscript, as did proofreaders Lor Gehret and Ben Tedoff. This was no small task. Their insights and suggestions were invaluable, and the book is far better as a result.

This project has afforded me the luxury of pursuing two of my life passions at the same time: graduate level physics and fourth-grade humor. In this respect, Leonard and I are a perfect team, and collaborating with him is an unmitigated pleasure. We last left the intrepid pair recovering from a wild rollicking roller coaster ride through the quantum world of entanglement and uncertainty. They were ready for something sedate, something reliable and deterministic, something classical.

Lenny and Art are hardly finished with their madcap adventure. And at the end of the ride Lenny tricks Art with a fake monopole. Well, maybe that is a bit overwrought, but to the beginner the relativistic world is a strange and wondrous fun house, full of dangerous puzzles and slippery paradoxes. Some basic grounding in calculus and linear algebra should be good enough to get you through.

Our goal as always is to explain things in a completely serious way, without dumbing them down at all, but also without explaining more than is necessary to go to the next step. Depending on your preference, that could be either quantum field theory or general relativity. The first volume on classical mechanics was mostly about the general framework for classical physics that was set up in the nineteenth century by Lagrange, Hamilton, Poisson, and other greats.

That framework has lasted, and provides the underpinning for all modern physics, even as it grew into quantum mechanics. In Volume III we take a historical step back to the nineteenth century to the origins of modern field theory. In his intuitive way he understood most of what Maxwell later combined into his unified equations of electromagnetism.

Faraday was lacking one element, namely that a changing electric field leads to effects similar to those of an electric current. It was Maxwell who later discovered this so-called displacement current, sometime in the early s, and then went on to construct the first true field theory: the theory of electromagnetism and electromagnetic radiation.

No inertial frame of reference is more entitled to be thought of as at rest than any other frame. How could it be possible for light to have the same velocity in every frame of reference? How could it be that light travels with the same velocity in the rest frame of the train station, and also in the frame of the speeding train? They pictured the world as being filled with a peculiar substance— the ether—which, like an ordinary material, would have a rest frame in which it was not moving.

In any other frame, moving with respect to the ether, the equations had to be adjusted. This was the status until when Albert Michelson and Edward Morley did their famous experiment, attempting to measure the small changes in the motion of light due to the motion of Earth through the ether. No doubt most readers know what happened; they failed to find any. But no matter how you tried to rescue it, the ether theory was ugly and ungainly. According to his own testimony, Einstein did not know about the Michelson-Morley experiment when in at age sixteen , he began to think about the clash between electromagnetism and the relativity of motion.

He simply felt intuitively that the clash somehow was not real. He based his thinking on two postulates that together seemed irreconcilable: 1.

The laws of nature are the same in all frames of reference. Thus there can be no preferred ether-frame. It is a law of nature that light moves with velocity c. As uncomfortable as it probably seemed, the two principles together implied that light must move with the same velocity in all frames. It took almost ten years, but by Einstein had reconciled the principles into what he called the special theory of relativity.

However, to this day you will still find a residue of the ether theory in textbooks, where you will find the symbol 0, the so-called dielectric constant of the vacuum, as if the vacuum were a substance with material properties. Students new to the subject often encounter a great deal of confusion originating from conventions and jargon that trace back to the ether theory.

An experienced ballplayer can take a quick look at a fly ball and from its location and its velocity know where to run in order to be there just in time to catch the ball. There is an obvious reason why classical mechanics is intuitive: Humans, and animals before them, have been using it many times every day for survival. We had to learn new mathematical abstractions and a new way of connecting them to the physical world. But what about special relativity?

SR does stretch our intuition, but the stretch is far more gentle. In fact, SR is generally regarded as a branch of classical physics. Special relativity requires us to rethink our notions of space, time, and especially simultaneity. Physicists did not make these revisions frivolously. As with any conceptual leap, SR was resisted by many. You could say that some physicists had to be dragged kicking and screaming to an acceptance of SR, and others never accepted it at all. Aside from the many experiments that confirmed the predictions made by SR, there was strong theoretical support.

While this conclusion was disturbing, it could not just be ignored—the theory of electromagnetism is far too successful to be brushed aside. Their precise measurements provided strong confirmation of SR. Lenny: Good idea, Art. Art: Where? Who is this guy Hermann? Lenny: Minkowski?

No kets either. Art: Why did Hermann build his Hideaway way out here in the middle of— what? A cow pasture? A rice paddy? Lenny: We just call it a field. You can grow just about anything you like; cows, rice, sour pickles, you name it.

Who knew? By the way, how come everyone here is so skinny? Is the food that bad? Lenny: The food is great. Hermann provides free jet packs to play with. Look out! Art: Goose! We could both stand to get a bit thinner. More than anything else, the special theory of relativity is a theory about reference frames. If we say something about the physical world, does our statement remain true in a different reference frame? Is an observation made by a person standing still on the ground equally valid for a person flying in a jet?

The answers to questions of this sort turn out to be interesting and surprising. In fact, they sparked a revolution in physics in the early years of the twentieth century.

I talked about them in Volume I on classical mechanics. Cartesian coordinates, for example, are familiar to most people.

A Cartesian frame has a set of spatial coordinates x, y, and z, and an origin. If you want to think concretely about what a coordinate system means, think of space as being filled up with a lattice of metersticks so that every point in space can be specified as being a certain number of meters to the left, a certain number of meters up, a certain number of meters in or out, from the origin.

It allows us to specify where an event happens. In order to specify when something happens we also need a time coordinate. A reference frame is a coordinate system for both space and time.

Skip to main content. Special Relativity and Electrodynamics. Lectures in this Course 1. In the first lecture of the course Professor Susskind introduces the original principle of relativity - also known as Galilean Invariance - and discusses inertial reference frames and simultaneity. He then derives the Lorentz transformation of Professor Susskind starts with a brief review of the Lorentz transformation, and moves on to derive the relativistic velocity addition formula. He then discusses invariant intervals, proper-time and distance, and light cones.

Leonard Susskind, Art Friedman – Special Relativity and Classical Field Theory

This is a great idea, since there is not much else of this kind, while lots of people inspired by a popular book could use something more serious to start learning what is really going on. The courses are available as Youtube lectures here. Book versions of some of the courses have now appeared, first one in collaboration with George Hrabovsky about classical mechanics, then one with Art Friedman about quantum mechanics.

To the reader: The authors of this book intersperse the text with conversations between Art and Lenny. The conversations are cute, fun, and give the text a playful feel. With that in mind, please meet my dear friend Andy I. Andy is a real theoretical physicist and holds a Ph. I can do physics, too.
