A, for your actual question, briefly outlining the steps. Two understanding quanti mechanics. Then, n two other things crucial for quanti Mechanics. One is complex numbers, complex variables. The second thing is linear algebra,. which is the theory of matrices and diagonalizing them and finding igan values all over the place. I mean literally, the name of schwortengers paper, where he invented theschortenger equation was quanta mechanics as an igen value problem. O and in heisenberg's version of quanta mechanics was maitrix mechanics. You need to now matreces, and you can learn all those things those are all things that typical mathphys
