Introduction To Modern Physics: Theoretical Foundations by John Dirk Walecka (PDF)

Description

Our understanding of the physical world was revolutionized in the twentieth century — the era of “modern physics”. This book, aimed at the very best students, presents the foundations and frontiers of today’s physics. It focuses on the following topics: quantum mechanics; applications in atomic, nuclear, particle, and condensed-matter physics; special relativity; relativistic quantum mechanics, including the Dirac equation and Feynman diagrams; quantum fields; and general relativity. The aim is to cover these topics in sufficient depth such that things “make sense” to students and they can achieve an elementary working knowledge of them. Many problems are included, a great number of which take dedicated readers just as far as they want to go in modern physics. Although the book is designed so that one can, in principle, read and follow the text without doing any of the problems, the reader is urged to attempt as many of them as possible. Several appendices help bring the reader up to speed on any additional required mathematics. With very few exceptions, the reader should then find the text, together with the appendices and problems, to be self-contained.

⭐Came brand new and arrived quickly.

⭐Excellent book.I know the author personally and the book is like listening to him!

⭐This is a great introductory text on the foundations of modern physics. The reader, undergraduate – graduate and professions, will benefit in many ways from the clarity of and depth of the presentation and the example problems.

⭐Thanks.

⭐The author, Prof. Dirk Walecka is a reknown physicist, and more so he is a great teacher. I thoroughly enjoyed this book.

⭐Professor Walecka is author of well known textbooks and this is another example of his great mix of clear explanations and broad perspective. Just to give a bit of salt to this review, let me start from what I did not like about it: the illustrations are very poor, compared to the high level of the text. I must say that the publisher should have made any effort to provide more elegant version of most plots…However, as I already said, the text is really good, expecially if you realize that each single chapter covers material which is usually introduced in entire courses. Of course, it is not possible to provide a full treatment of everything into a single (light) book. On the other hand, this is a unique chance to put so many puzzle pieces together, and provide the links between them. Just have a look at the table of contents to realize how wide the puzzle is. Then, read through the chapters to find almost all fundamental aspects with a rather complete introduction, including the mathematical approach.I don’t know if there is a single course which could be based on this textbook. On the other hand, it has been a great pleasure for me to have a broad review of so many different aspects of modern physics into a single book. I read it from the first to last page in a couple of weeks, and I enjoyed almost every paragraph.

⭐Walecka is well known in physics as the co-author of Quantum Theory of Many-Particle Systems, which is a standard and rather advanced graduate text. Here in this new book, he takes a broader approach. The level of discourse is about that of the senior or honours undergraduate level, or perhaps a first year in grad school.The scope is modern physics, where this is defined as quantum mechanics and relativity. Each chapter touches upon key ideas. The mathematical treatment is given rather briefly; probably inevitable due to space limitations.One key result is the Feynman diagram. You can see how this maps to an equivalent integral and thus ultimately to a number, which is the scattering cross section. Really nice, and the intuitive meaning of the diagram demonstrates why the Feynman diagram was a seminal concept and a very practical tool in high energy physics.

⭐Dans cet ouvrage vous avez moins de détails que dans les autres où chaque chapitre de ce livre équivaudrait à plusieurs parties (les calculs sont souvent reportés aux ouvrages de référence) ce qui permet d’avoir une vision synthétique du sujet couvert.
