SUMMARY

This discussion centers on the comparison between Heisenberg's matrix mechanics and wave mechanics in quantum mechanics (QM). It establishes that while both formulations are interconnected, matrix mechanics serves as a more abstract and general framework, whereas wave mechanics is often more practical due to its reliance on differential equations. Recommended resources for studying matrix mechanics include J. Townsend's text and J.J. Sakurai's book, with Dirac's Quantum Mechanics suggested for further reading.

PREREQUISITES
  • Understanding of quantum mechanics fundamentals
  • Familiarity with differential equations
  • Knowledge of Heisenberg's principles
  • Basic concepts of angular momentum in QM
NEXT STEPS
  • Study Heisenberg's matrix mechanics in-depth
  • Explore J. Townsend's and J.J. Sakurai's quantum mechanics texts
  • Read Dirac's Quantum Mechanics for advanced insights
  • Investigate the applications of differential equations in wave mechanics
USEFUL FOR

Students of quantum mechanics, educators in physics, and anyone seeking to deepen their understanding of matrix mechanics versus wave mechanics.

For someone who's bored with wave mechanics, would you suggest studying Heisenberg's matrix mechanics (which was the first formulation)?

Are there any major/conceptual differences? (except one talks about waves and the other doesn't!)
And for someone who wants to study it, what books/online docs would you suggest? Damn, all QM I have ever found covers wave-mechanics majorly, and some briefly mention matrix mechanics when the title hits angular momentum.

Look at J. Townsend's text; if you find it too pedantic try J.J. Sakurai. Both are certainly in your school's library.

A short answer - there are major superficial differences. The "matrix mechanics" as you call it is a very general and abstract formalism; wave mechanics falls out easily as a special case. It is often more useful to work with waves, where everything is in differential equations.
 
Read Dirac's Quantum Mechanics.
