This question already has an answer here:

I am an engineering student (CSE) in India..But recently I have developed a strong love to physics..I want to learn physics and understand it in deep..I know physics is the search of deep fundamental laws of nature.That means I need to start from first principles and extrapolate from it?How should i learn physics?

start from learning concepts of class 11 and 12 –  Akash Aug 31 '13 at 4:33

As always I refer to 't Hooft's list of subjects to learn more or less in order to become a theoretical physicist. –  Michael Brown Sep 13 '13 at 12:37
    
@MichaelBrown I don't really think people should follow t'Hooft's order to the letter. Schools and universities are fond of keeping a lot historical baggage in the syllabus and piling it on students. The newer topics are more fundamental and generalized. 100 years from now, the list of topics will probably double, are we going to still ask students to study 'classical electrodynamics'? –  dj_mummy Sep 13 '13 at 15:34

Before this question gets closed, let me quickly post an answer.

First of all, I must warn you, "Learn it in order.". You know those popular - science, math - free books? Stay away from them. They give you the wrong impression that physics is math-free, and that by reading that, you'll already know a lot, etc., BUT THAT'S FALSE/.

Popular Science will not gett you anywhere.


Secondly, what do I mean by "Learn it in order."? I mean, that to learn physics, you must go like this:

  • Kinematics

  • Newtonian Mechanics

  • Lagrangian Mechanics

  • Hamiltonian Mechanics

  • Newtonian Gravity

  • Coulomb's Electricity

  • Maxwell's Electromagnetism

  • Special Relativity

  • General Relativity

  • Old Quantum Theory

  • Heisenberg Matrix Quantum Mechanics

  • Schrodinger Wave Mechanics

  • Feynman (?) Path Integrals

  • Klein - Gordon Equation

  • Dirac Equation

  • Weyl Equation

  • Spinors

  • Variational Formulation of Quantum Mechanics

  • Quantum Electrodynamics

  • Yang - Mills Theory

  • Quantum Chromodynamics

  • Electro - Weak Theory

  • Higgs Mechanism

  • Standard Model

  • String Theory


Now, what about some good sources to learn all of theseq ?


For the Math, see this .

A downvote? What's wrong with this answer? Someone hates the sources I mentioned, I suppose. Like, all of them. –  Dimensio1n0 Aug 31 '13 at 5:07
    
I didn't downvote. A good list. But I feel wikipedia is not the best place to learn physics. It is an excellent index to keep track of the popular topics in physics but it's instructive value is questionable. The articles there lack consistency and context. –  dj_mummy Sep 13 '13 at 11:39
    
@dj_mummy: I know that. I should probably link to the old id's. Most of the ones I linked to are great according to me. But a lot of them are plain horrible and popular-level /. –  Dimensio1n0 Sep 13 '13 at 11:53

@Nick: My point is precisely that I didn't cover the mathematics, not that it's not necessary. Of course, the math is necessary! . –  Dimensio1n0 Sep 13 '13 at 15:10

@Nick: Yes, I've added a small part in the end about the math just now. –  Dimensio1n0 Sep 13 '13 at 15:28
