Discussion Overview

The discussion revolves around the order in which to learn physics, particularly for individuals with a strong mathematical background but little knowledge of physics. Participants explore various foundational topics such as classical mechanics, electromagnetism, and quantum mechanics, and suggest a progression through these subjects.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests starting with classical mechanics, followed by electron dynamics, special relativity, quantum mechanics, and relativistic theory, noting that some calculus of variation knowledge would be helpful for classical and quantum mechanics.
  • Another participant proposes a typical order of study: classical mechanics, electromagnetism, optics, and then modern physics.
  • A further suggestion includes beginning with a general introduction to physics using a specific textbook, followed by a structured approach to classical mechanics, special relativity, electromagnetism, optics, quantum mechanics, thermodynamics/statistical mechanics, and condensed matter.

Areas of Agreement / Disagreement

Participants express various sequences for learning physics, indicating no consensus on a single order. Multiple competing views on the progression of topics remain present in the discussion.

Contextual Notes

Some participants mention prerequisites such as calculus of variation for certain topics, but these are not universally agreed upon. The discussion reflects different educational approaches and personal preferences without resolving which is the most effective order.

Who May Find This Useful

Individuals new to physics with a strong background in mathematics, educators seeking to structure a curriculum, and students considering their learning path in physics may find this discussion relevant.

I have little to no knowledge in physics but I have a very strong understanding of the main topics in maths (trig, calculus etc). What should I start with in physics and what order should I progress in? What're the main topics I should know? I've heard of (but know nothing about) classical mechanics, relativistic mechanics, quantum mechanics and quantum field theory. Are there any other major topics I should do as well?

learn classical mechanics first, then continue with electron dynamics, and then special relativity, continued with quantum mechanics and relativistic theory.

For classical mechanics and quantum mechanics, it would be really helpful knowing some calculus of variation to begin with, but not necessary.

Quantum field theory will require quite a bit more.
 
The usual order is classical mechanics, electromagnetism, then optics and modern physics
 
Following a typical undergraduate physics curriculum:

Start with a general introduction to physics. I recommend Physics by Resnick, Halliday, and Krane. You can pick up the 4th edition for $1 on most websites. You'll get a broad, conceptual view of the most common fields in physics.

Then you can focus on the specifics.

Classical Mechanics
Special Relativity
Electromagnetism
Optics
Quantum Mechanics
Thermodynamics/Statistical Mechanics
Condensed Matter
