SUMMARY

The discussion centers on the prerequisites for a Quantum Mechanics (QM) class, particularly for students lacking a classical mechanics (CM) background. Key concepts highlighted include the Hamiltonian and Hamiltonian equations of motion, as well as angular momentum. Recommended resources for self-study include Susskind's lectures on classical mechanics and the book "Classical Dynamics of Particles and Systems" by Marion and Thornton. The consensus is that while a foundational understanding of CM can enhance comprehension of QM, it is not strictly necessary for initial engagement with the subject.

PREREQUISITES
  • Hamiltonian and Hamiltonian equations of motion
  • Angular momentum concepts
  • Classical mechanics fundamentals
  • Mathematical formalism in physics
NEXT STEPS
  • Study Susskind's lectures on classical mechanics
  • Read "Classical Dynamics of Particles and Systems" by Marion and Thornton
  • Watch Balakrishnan's classical mechanics lectures on YouTube
  • Explore the relationship between classical mechanics and quantum mechanics
USEFUL FOR

Physics majors, particularly those transitioning from classical mechanics to quantum mechanics, as well as educators and students seeking to bridge gaps in foundational knowledge for advanced physics courses.

Hey everyone, I'm a physics major in junior year that missed out on my classical mechanics class this fall semester because of some prereq stuff. I emailed the professor teaching QM next semester and got in without the necessary classical prereq. He said I should go over "the Hamiltonian and Hamiltonian equations of motion, angular momentum, and some others."

I plan on going over this stuff this winter break, and was wondering what other concepts I might need and where/how to study and review them. Any good books/resources? Thanks.

I think Susskind's lectures on classical mechanics could be a good resource he introduces the CM necessary for QM but its not enough:

Classical Dynamics of Particles and Systems (Marion and Thornton) is a good book on the subject
also there are these lectures on classical mechanics by Balakrishnan:

I don't think you need a detailed knowledge of CM to understand QM.
 
Judging from most junior level QM classes I've heard about, you'll be just fine. Even if you don't know what a hamiltonian is, it will probably be explained. The knowledge of classical mechanics certainly can enrich the quantum mechanics, but usually isn't essential the first time through where you focus primarily on the physics rather than the mathematical formalism (sometimes relegated even to a side note!).
