Linear Algebra Gives Me PTSD

Linear Algebra Gives Me PTSD
The mathematical monster that haunts linear algebra students everywhere! A Hermitian matrix (where A equals its own transpose) is like that equation that follows you home at night after the exam. Students who've survived advanced linear algebra know the trauma. You close your eyes and still see eigenvalues. You hear matrices being diagonalized in your sleep. The Hermitian property seems innocent enough on paper, but it's the gateway drug to quantum mechanics and other mathematical nightmares. Your therapist might not understand, but that symmetric crab with its perfectly balanced properties is very real to anyone who's ever had to compute a basis of eigenvectors at 3 AM.

Finding a Hermitian operator that commutes with the Hamiltonian is like striking quantum gold—it gives you those sweet, sweet conserved quantities. But the moment you're dealing with degenerate states, you start eyeing that operator like it's your ex who just texted "we need to talk." Suddenly, perturbation theory looks mighty attractive. For the uninitiated: Hermitian operators represent physical observables in quantum mechanics. When one commutes with the Hamiltonian (H), it means you can measure both properties simultaneously—a rare luxury in the quantum world. Degenerate states, however, are quantum mechanics' way of saying "it's complicated."
