Art arrives late and pulls up a stool next to Lenny. The fact that the authors can make me even feel like I understood almost everything is a great achievement. Perhaps even worse than one might think, since when I first read it Styx was a big band. What You Need To Know. I just now finished Special Relativity and Classical Field Theory. As to so-called Abstract Index Notation. This is especially important in the later chapters on classical field theory.
The full series delivers over 100 lectures amounting to something on the order of 200 hours of content, with some of the individual lectures having received over a million YouTube views. It took me some time to learn, for example, that bundle and sheaf methods were, roughly speaking, dual to each other. I have studied these subjects at grad school but the way in which the different subjects were introduced here is much better. The third volume in the bestselling physics series cracks open Einstein's special relativity and field theory Physicist Leonard Susskind and data engineer Art Friedman are back. This time, they introduce readers to Einstein's special relativity and Maxwell's classical field theory. Special attention is given to the realization of symmetries in particle physics: global and local symmetries, explicit, spontaneously broken, and anomalous continuous symmetries, as well as discrete symmetries. Keep in mind that in field theory the Xi are not degrees of freedom; they are merely labels that label the points of space.
I think that most physicists writing indices have a geometrical object in mind. They are two different things. While one can criticize string theory, it seems to have directly or tangentially led to some interesting other theories and some new math. . The second, on quantum mechanics, was nowhere near as successful at getting the concepts across, in no small measure because those concepts are much harder to grasp than the concepts involved in the kind of physics Newton dealt with.
In addition, Susskind has made available video lectures over a range of supplement subject areas including: advanced quantum mechanics, the , , , and. But you will need to do all the of exercises to grasp everything. You must read and understand the equations as well as the text. One of the fathers of string theory, he is the author of The Black Hole War and The Cosmic Landscape. His research interests include string theory, quantum field theory, quantum statistical mechanics and quantum cosmology. I cannot wait for General Relativity to come out.
For example, if you go into space and apply a constant amount of force to your body, you should be able to accelerate to a velocity faster than that of light! This is one of the best physics books I have read these recent years. But I didn't stop and do the exercises. Challenging, lucid, and concise, The Theoretical Minimum provides a tool kit for amateur scientists to learn physics at their own pace. Using their typical brand of real math, enlightening drawings, and humor, Susskind and Friedman walk us through the complexities of waves, forces, and particles by exploring special relativity and electromagnetism. They hold your hands to some extent, by including most of the intermediate steps in any derivation, and repeating key equations and diagrams multiple times. Art Friedman is a life-long student of physics, and his career encompasses software engineering, teaching, and writing. This is much heavier going, but explains things like the electromagnetic field and leads you up to the equations, discovered by James Clerk Maxwell, that explain electromagnetism.
He is the author of Quantum Mechanics with Art Friedman and The Theoretical Minimum with George Hrabovsky , among other books. The courses collectively teach everything required to gain a basic understanding of each area of modern physics, including much of the fundamental mathematics. Loooking forward to the next book on General Relativity. This is the third book; it follows directly on what was presented in the first book on classical physics, and I'm not sure why Susskind the principal author decided to separate the two by the book on quantum theory, which is based on different ideas and different math. If you are interested in manifolds with some extra structure, e.
But I didn't stop and do the exercises. Industry Reviews Witty and insightful. What You Need To Know. Some sections on classical field theory got a bit boring; it felt like the same repeated derivations based on Euler-Lagrange equations for a bunch of slightly-varied Lagrangians. So with all that, I give this book a 5 out of 5. The book was initially published on January 29, 2013 by.
Not surprisingly, the degrees of freedom of field theory are fields. Special Relativity and Classical Field Theory: The Theoretical Minimum. I found it thrilling -- Robert P. Despite this, I was surprised at how much of the book I understood; essentially almost everything except the last chapter, which as in most math books based on courses or lectures sped up to squeeze in everything the authors wanted to cover before the class ended. The setup of the book was so logical and the mathematical development was so well paced that I could feel much greater mathematical sophisticat Inspired This is the three book in the series I have read. This is book 3 in a series, yet I read 3 first, then 2, then 1. Now, I will not say that I could erase all the equations and mathematical reasoning segments from the book, and as an exercise, recreate them from memory, calculation, and my own reasoning, but I will say that if you go over the material at a comfortable pace and are willing to look back a chapter or two or three to remind yourself of some key detail, you will be very well rewarded with a view into special relativity, electrodynamics, and classical field theory.
If equations are not your thing, try which does a very good job of explaining special relativity using only Minkowski diagrams and no equations. With the third installment of The Theoretical Minimum, it seems that Leonard Susskind and Art Friedman have found their respective stride. For real understanding, one simply must do the math. They are presented with a minimum of technical details, the discussion of the main ideas being more important than the presentation of the typically very technical mathematical details necessary to obtain the final results. Perhaps you can guess which one it is as we go along.
But you should at least read book 1 because it derives regular Newtonian mechanics from a Lagrangian function and the principle of least action. This is physics the way it's really done, in all its glory, nothing swept under the rug. Nobody knows how to make logical sense out of more than one time dimension. It deservedly became a best seller. Wind velocity is a vector field because velocity has a direction, which may also vary over space and time. Video recordings of the complete lectures are available.
