Discussion Overview

The discussion revolves around the order in which one should learn physics to achieve a comprehensive understanding of the subject. It touches on self-teaching versus formal education and the challenges associated with mastering physics concepts.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant requests a structured learning path for mastering physics, explicitly asking for a comprehensive order of topics.
  • Another participant asserts that it is impossible to learn everything in physics, suggesting a limitation to the scope of knowledge.
  • A third participant proposes a starting point for self-teaching physics, recommending a specific resource for foundational learning.
  • Further, a participant discusses the rarity of learning physics in isolation, emphasizing that most successful physicists have formal education and structured coursework.
  • This participant outlines a typical sequence of topics covered in undergraduate physics programs, including classical mechanics, electrodynamics, thermodynamics, special relativity, quantum mechanics, and statistical mechanics.
  • They also note the importance of mastering prerequisite mathematical concepts such as vector calculus and differential equations before advancing to higher-level topics.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of learning all of physics and the necessity of formal education. There is no consensus on a definitive learning path, as some advocate for self-teaching while others emphasize the importance of structured coursework.

Contextual Notes

The discussion highlights the challenges of self-teaching physics and the potential limitations of learning in isolation. There are also unresolved assumptions regarding individual learning styles and the effectiveness of various educational approaches.

Can someone tell me what order someone should learn physics until they can say that they totally know physics (please don't write something like you can never learn everything in physics)

Thanks!

you can never learn everything in physics
 
I'll start off by saying that it's very rare for someone to be able to learn physics in a vacuum. Yes, it's possible, and people like Issac Newton are examples. But such people are exceptional cases, and even most of the famous physicists studied formally (in thinking of examples, Newton was the only one that came to mind, and even he had a Bachelors degree when he formulated his laws of mechanics). When you don't have a professor and the stress of grades pressuring you to study for exams and do homework, it usually just doesn't work out. But hey, maybe you're that exceptional case, so I'll just list off the order of coursework that most physics programs take you through.

Basic, calculus based classical mechanics
Basic, calculus based electrodynamics
Optics, wave mechanics, basic thermodynamics, and special relativity
(By this point you'd better have picked up vector calculus and differential equations)
Basic quantum mechanics
Advanced mechanics
Advanced electrodynamics
Advanced quantum mechanics (you'll likely need some linear algebra before this one)
Statistical mechanics

This is the absolute minimum usually required for an undergraduate degree in physics. I'd say that if you can master this material (which almost always comes by going to college and taking the courses), then you're in a position such that you can pick up textbooks or papers and start learning on your own. And even then it's hard. Maybe it's just my learning style, but even in graduate school I've learned a lot just by going to class and doing my homework.
