I'm a senior physics major in the first semester of a two semester QM sequence using Griffiths. All of the physics majors talk about how great quantum mechanics is and how it is the pinnacle of the undergrad physics degree. The upper level physics courses seem to build up the foundation that one needs in order to make it through quantum mechanics, etc. Well, I am extremely disappointed with the material so far...
We had our first exam and it essentially felt like a math test. I did very well but felt that I hardly understood anything. I have gained no intuition about what is physically going on so far in the course. Sure, there is quantization of energy states for a particle. Sure, a particle's state can be described by a wave function and its observables by an operator. But what does this REALLY mean? It's extremely frustrating to not understand what is going on and just chugging through the math. I decided to major in physics because I wanted to understand how things work, and so far classes like classical mechanics, optics, E&M, and thermo/stat mech have been extremely satisfying. I just can't figure out what I'm missing with quantum mechanics that other physics majors seem to get, or at least what they find satisfying/interesting about it. Is it simply the mathematical gymnastics that people like?
For the first time, I feel that I'm losing motivation in a physics course... Did anyone else feel this way with upper division quantum mechanics?
