What order should I learn physics in?

[johnathon]

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

I would recommend starting with classical mechanics as it provides a strong foundation for understanding other branches of physics. This includes topics such as kinematics, dynamics, and energy. With your strong understanding of math, you should be able to grasp these concepts easily.

Next, I would suggest learning about electromagnetism, which is the study of electric and magnetic fields and their interactions. This is an important topic as it is the basis for many modern technologies.

After that, you can move on to thermodynamics, which deals with the transfer of heat and energy. This is crucial for understanding how energy is used and transferred in various systems.

Once you have a good grasp of these topics, you can then delve into modern physics, which includes relativity and quantum mechanics. These branches of physics revolutionized our understanding of the universe and are essential for understanding the behavior of particles at a subatomic level.

As for other major topics, I would also recommend learning about optics, which is the study of light and its properties, and astrophysics, which deals with the physics of the universe and celestial objects.

Ultimately, the order in which you learn physics may vary depending on your personal interests and goals. However, I would suggest starting with classical mechanics and then progressing to more complex and modern topics. It is also important to continuously review and reinforce your understanding of the fundamentals as you move on to more advanced topics. Good luck on your journey in learning physics!
