Classical Mechanics for Mathematician

Click For Summary

Discussion Overview

The discussion focuses on finding suitable resources for learning classical mechanics from a mathematician's perspective, particularly for someone without a background in freshman physics. Participants suggest various books and approaches to bridge the gap between mathematics and mechanics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks recommendations for books to learn classical mechanics, citing their mathematical background and lack of physics coursework.
  • Another participant suggests V.I. Arnold's "Mathematical Methods of Classical Mechanics" as a suitable resource, highlighting its connection to differential forms.
  • A question is raised about whether Arnold's book is self-contained regarding physical intuition and if it can be understood without prior freshman-level physics knowledge.
  • A different participant recommends a combination of video lectures and specific textbooks to emphasize calculus in learning mechanics, suggesting a structured approach to studying the material.
  • Another participant mentions Spivak as an excellent suggestion for learning mechanics, proposing a comparison of books in a library.
  • One participant emphasizes the geometric aspects of classical mechanics and recommends both Arnold's book and E.T. Whittaker's "A Treatise on the Analytical Dynamics of Particles and Rigid Bodies," noting its availability online.
  • There is a suggestion to follow up with "Dynamical Systems IV: Symplectic Geometry and Its Applications" and a reference to a set of lecture notes on symplectic geometry.

Areas of Agreement / Disagreement

Participants express a variety of opinions on suitable resources, with no consensus on a single best approach or book. Multiple competing views on how to effectively learn classical mechanics remain present.

Contextual Notes

Some participants highlight the importance of physical intuition and foundational knowledge, which may vary among individuals. The discussion reflects differing levels of familiarity with physics concepts and the mathematical rigor expected in various texts.

Hi!
I am looking for suitable ways to learn mechanics in mathematician's perspective.
I went through:
- multivariable calculus from Spivak,
- real analysis from Pugh,
- differential equations from Hirsh/Smale/Devaney (mostly focusing on linear system, existence & uniqueness, nonlinear dynamical system, bifurcation, and brief touch on chaos) (so no application covered)
- differential geometry from Pressley (but I hate pressley, so I am going to review through doCarmo)
- topology from Willard (but not all of them)

The problem is I did not take freshman physics coures (because of annoying labs;;)

My goal is to be able to read Abraham/Marsden's Foundations of Mechanics or something
of that level.

I was thinking of reading differential equations book's applications section first and... idk.

What books do you think is suitable for me to start learning classical mechanics?
 
Physics news on Phys.org
V.I. Arnold's Mathematical Methods of Classical Mechanics sounds like it would be suitable. You'll finally get to see those differential forms from Spivak in action!

But is Arnold self-contained in terms of physical intuition?
Do you think Arnold is readable without freshman-level physical knowledge?

Here's an idea if you want to do the basics of mechanics with more of an emphasis on calculus than most introductory approaches - Mix:
http://www.pa.msu.edu/courses/phy233b/VideoLectures.html
http://www.pa.msu.edu/courses/2010fall/PHY321/VideoLectures/
with reading both https://www.amazon.com/dp/0201073927/?tag=pfamazon01-20 & https://www.amazon.com/dp/0070843570/?tag=pfamazon01-20 (http://archive.org/details/SchaumsTheoryAndProblemsOfTheoreticalMechanics).
I'd take notes from the video in the first link first, then the second link, then read the corresponding section of Symon finally doing the schaums sections & Symon's problems together last. it'd be a good idea to go through the Yale videos as well. Then you could go onto Lagrangian https://www.amazon.com/dp/0070692580/?tag=pfamazon01-20 & Arnol'd without that soul-destroying headache. If you want to really rush things then at least watch the videos before going on as they are the best ones I've found & do the most out of all the basic ones I've seen.

I completely forgot about Spivak--also an excellent suggestion! Ideally you could compare these two books in a library and see which one you prefer.
 
Classical mechanics is has a very strong geometric flavor. That is, you can learn a lot of pretty mathematics by learning classical mechanics.I would strongly recommend either Mathematical Methods of Classical Mechanics by V.I. Arnold or An Treatise on the Analytical Dynamics of Particles and Rigid Bodies by E.T. Whittaker (out of copyright/print; legally available on-line here).

After that, purchase Dynamical Systems IV: Symplectic Geometry and Its Applications. There is also a really nice set of lecture notes by "www.math.princeton.edu/~acannas/Papers/symplectic.pdf" .
