Where Can I Find a Comprehensive Introduction to Modern Physics Theories?

Click For Summary

Discussion Overview

The discussion revolves around the search for a comprehensive introduction to modern physics theories, including quantum mechanics, relativity, and various advanced topics like string theory and quantum gravity. Participants explore the feasibility of finding a single book that adequately covers these diverse and complex subjects.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant requests recommendations for a book that covers a wide range of modern physics theories, seeking an overview of their explanations and limitations.
  • Several participants argue that it is unrealistic to expect a single book to provide a meaningful introduction to such a broad array of theories, emphasizing the need for substantial effort and time to understand physics.
  • Some participants suggest that popular science books may not provide the depth required to truly understand the theories, as they often skip vital details necessary for comprehension.
  • Others acknowledge the value of popular science books for general knowledge but caution that they may lead to misunderstandings about the actual theories.
  • Specific book recommendations are made, including titles by Roger Penrose, Ian D. Lawrie, John Baez, Gerard 't Hooft, and Lee Smolin, with varying opinions on their suitability for the original request.
  • There is a discussion about the distinction between learning about theories and learning the theories themselves, with some participants expressing concern over the prevalence of personal theories among lay readers.

Areas of Agreement / Disagreement

Participants generally disagree on the possibility of finding a single comprehensive book that covers all requested theories effectively. While some recommend specific titles, others maintain that no such book exists that meets the criteria outlined in the initial request.

Contextual Notes

Participants note that the theories mentioned range from well-established to speculative, which complicates the search for a suitable introductory text. The discussion highlights the varying levels of depth and rigor required to understand these theories.

Can someone recommend me a modern physics book, that includes introduction to all the different theories like quantum mechanics,quantum field theory,special relativity,general relativity,standard model,string,m-theory,supersymmetry,superstrings,quantum gravity,loop quantum gravity etc(if I missed any other theory) ,so that I can get essence of what each theory tries to explain,to what extent they are successful and wheres the problem(i.e. theory of everything).

If you know any book that does this,Please let me know!

You want to read only one book for all of these theories?!
So, honestly, physics is not for you.
 
Just "introduction" to all these theories.

Its just impossible. Such a book does not exist. You can't learn physics this way. If you're not willing to put enough effort and time, you can't learn anything. And the fact that you're looking for such a book, means you're aiming to invest much much less than what is needed for gaining only a minimum understanding of such theories. Come back when you are willing to invest more.
 
The point is that you have listed such a wide variety of theories. From theories whoch are well established and tested to theories which at this point are only hypotheses which may never be testable. No book is going to give you an introduction to all these subjects. The closest thing you will get would be some popularised texts, but these texts are not texts to learn anyhing from.

Actually, there is an excellent book by Lee Smolin, named "The Trouble with Physics". On one hand, its prose, not a textbook; on other, it gives the reader an excellent exposition of the development of ideas in physics, starting from Copernicus and Kepler, analysing any significant milestone since, and introducing all the key notions of the contemporary string theory in a digestible way. I am half way through this book, and it has given me a clear roadmap (perhaps not balanced) of what's going on in the last 30 years of high-energy physics. It teaches one to think of physical ideas with clarity and objectiveness. I totally love it.
 
In my opinion:

Modern Physics/Serway

meets your requirements

It's an excellent book ,very well written !

Why can't you learn things from popular books?

Because they skip vital details in how the theory is constructed and how it makes predictions. As such, you cannot learn anything about the actual theory. At best, you can learn about the theory, but not enough to judge its merits.

That makes sense. But there isn't anything wrong w learning about stuff than delving right into the theory of stuff

As long as you realize that you are only learning about stuff and not really learning the stuff there is nothing wrong with it. However, the distinction is not clear to many laymen, which results in a large number of personal theories. That is where it goes wrong.

Yes that says it well. See I'm reading a book on cosmology (tegmark' s mathematical universe) and I've learned about things in cosmology and questions being asked, but I couldn't tell you why the theories make sense. I've read Liddle's Introduction to cosmology and for the most part I understood what he was saying but had no idea how he got certain Friedmann equations or why he used them when he did.

The problem is that you never know, whether the popular book is correct. There are a few very good popular-science books, among them Weinberg's The first three minutes on cosmlogy or Ledermann's The God Particle (despite the nonsense title). Many popular books however, simplify the issues they discuss more than possible and they become almost erratic.
