I have become so annoyed by the lack of mathematical detail in the physics textbooks. For example, to study Foundations of Quantum Mechanics, I had to spend hours and hours doing background reading from books, the net and Wikipedia until I got my way aroung vectors spaces and its nooks and crannies. I think I will have to do the same next year when I take the General Relativity course. This is becoming so annoying and actually I am beginning to think I should have studied maths instead of physics, so I could have known more mathematics and felt satisfied and then I could have specialised in theoretical physics. This is actually making me wonder if I should self-study mathematics from the freshman upto senior level just so the mathematics is not so demotivating?
