In summary, The Road to Reality by Roger Penrose would be a worthwhile read for someone with a solid understanding of math but little knowledge of physics. However, the book is not an easy read and may require additional references to fully comprehend the material. For a thorough understanding of physics, it is necessary to put in the hard work and not rely on just one book. Watching Susskind lectures online may also be a helpful resource.

The Road to Reality--worthwhile for someone who knows more math than physics?

Like the title says I have a solid understanding of a fair amount of math (multi and single variable calculus, linear algebra, differential equations, differential geometry) but essentially no physics except for a high school algebra based mechanics course.

Would Roger Penrose's The Road to Reality be a worthwhile endeavor for someone like me, so as to give myself a more rigorous overview of modern physics? I realize of course that there's no substitute for many years of training in physics, but perhaps as an introduction that wouldn't be too simple or too limited?

I think it's a worthwhile endeavor, but don't underestimate the difficulty of the book, the "popular science" label, not withstanding.

In order to understand a lot of it, you would end up having to look at other references along the way, so don't think you can really get away with just one book if you are going to learn about physics properly. If you want a superficial knowledge of physics, you can read one book; if you want substantial knowledge, there's really no shortcut to all the hard work. Depends on what your goal is with the physics. If it is just to get an idea, you can read popular books. If it is to give a broader background for math, a lot of physics topics are nice to know, but not strictly necessary. I always thought when I took an electromagnetism class, it gave a big boost to my mathematical abilities and contributed significantly to my understanding of many mathematical topics, including vector calculus and differential forms.

If you only are willing to read one book, I would suggest being less ambitious and just starting at the beginning with calculus-based introductory physics. If you wanted two books, I would suggest adding electromagnetism on top of that.

Another thing to try might be to watch the Susskind lectures, which you can find online.
 

1. Is "The Road to Reality" a good book for someone who is more knowledgeable in math than physics?

Yes, "The Road to Reality" is a great book for someone who has a strong understanding of math. The author, Roger Penrose, provides in-depth explanations and mathematical proofs to support his explanations of complex physics concepts.

2. Is the book suitable for self-study or is it more geared towards classroom use?

The book is suitable for both self-study and classroom use. Penrose breaks down the material into manageable sections and provides exercises for readers to test their understanding. However, some background knowledge in physics may be helpful for self-study.

3. How difficult is the book to understand?

The book is considered to be challenging, but not impossible, to understand. It covers a wide range of topics and assumes some prior knowledge in mathematics and physics. However, Penrose's clear writing style and thorough explanations make it possible for dedicated readers to understand the material.

4. Does the book cover advanced topics in physics?

Yes, "The Road to Reality" covers advanced topics in physics such as relativity, quantum mechanics, and string theory. It also delves into more abstract concepts such as topology and geometry.

5. How long does it take to read and understand the entire book?

The time it takes to read and understand the book will vary for each individual. It is a lengthy and dense book, so it may take several weeks or even months to fully grasp the concepts. However, with dedication and a strong foundation in math and physics, it is possible to understand the material within a reasonable amount of time.
