Apostol vs Spivak for physicists

Click For Summary

Discussion Overview

The discussion revolves around the comparison of two mathematics textbooks, Apostol and Spivak, and their relevance for physicists. Participants explore which book might be more beneficial depending on the specific area of physics one intends to pursue, as well as the transition from popular calculus books to more rigorous mathematical texts.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • Some participants suggest that the choice between Apostol and Spivak depends on the specific field of physics one is interested in, with Spivak being more suitable for those leaning towards mathematical physics.
  • Others argue that both Apostol and Spivak may be overly advanced for general physicists, who might benefit more from popular calculus books.
  • A participant questions the assumption that Apostol is easier than Spivak, noting that their experiences differ and highlighting that Spivak's exercises may be more challenging despite its readability.
  • There is a discussion about the prerequisites for studying Spivak, with one participant inquiring if a computational calculus class would suffice.
  • Some participants express uncertainty about their ability to tackle the material, with one mentioning the difficulty of leaving questions unanswered.
  • Another participant suggests setting time limits for completing exercises to manage the workload effectively.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which book is definitively better for physicists, with multiple competing views regarding the difficulty and appropriateness of Apostol and Spivak for different areas of physics.

Contextual Notes

There are varying opinions on the difficulty levels of Apostol and Spivak, as well as the appropriateness of different preparatory courses for studying these texts. The discussion reflects a range of experiences and expectations regarding mathematical rigor in physics education.

Hello PF!

I was wondering which would be more helpful for a physicist.

Also a little bit of a tangent, if I learn calculus from one of the "popular" books, how would I go back to rigorous math? And where would it be useful for a physicist?

Thanks :)

"Physicist" is a big word, it can mean a lot of things. It might be somebody into experimental condensed matter theory, or somebody into mathematical physics and string theory.

Clearly, the level of math books one should read depends on what kind of physicist they want to be and how interesting they find the mathematics.

For a general physicist, both Spivak and Apostol would probably be overkill. One of the "popular" calc books will work just fine. If you are interested in mathematics however, then you can try Apostol.

If you're going into mathematical physics such as string theory (which I understood from your previous posts), then Spivak is a must to read. But it shouldn't be your very first book to read. Try some easier book like Lang or Apostol first. Spivak isn't really calculus anyway, but an intro to analysis.

As is Apostol, with some linear algebra thrown in. What makes you think Apostol is easier than Spivak? I have experience only with Apostol, but I've never seen that opinion before.
 
Hmm, I am not sure which part of physics I will end up in, but I guess Spivak can't hurt. I didn't realize that Spivak > Apostol, thanks. Also does a computational calc class work as a prereq for spivaak?
 
I think you have Spivak now and probably you can answer half of the questions, that should be enough success to work through it. But if you're someone like me who hates to leave a question unconquered, it may prove difficult.
 
In that way, I am just like you, verty. How long do you think it might take to do?

In my opinion, Spivak is easier to read because Apostol's proofs are less detailed. However, Spivak's exercises are harder.

I would say they are both significantly harder than Lang, which is a very good introductory book.

Well I think you'll have to set some time limits, I mean you can't take a week to finish a chapter's questions. Probably you'll want to say, I'm going to try to answer all the questions but after 2 days, I'm moving on. But actually I would only do the questions that have answers (the easier questions I mean), go through book doing just those and come back later to try the harder ones.
