I for one am not satisfied with my professor's presentation of QM. The book she uses for the class is terrible(Peebles) and doesn't do a good job transitioning students from a classical mechanics mindset to a quantum mechanics mindset; Peebles is a graduate level textbook and so many of the concepts introduced in quantum mechanics are by-passed and we are assume to know , even though it is an introductory QM class for undergrads who had only had classsical mechanics and a modernphysics class; For the first few lectures of class, The correspondense principle is not introduced and I presume it will not be introduced for the remaining lectures since its the principle that connects classical mechanics with quantum mechanics; Concerning the mathematical formulation for QM, The math , which is mainly linear algebra and vector calculus, is not difficult to learn; However,I wish I were told why we use schrodinger equation and why the potential energy can be greater than the total energy , instead of just told to memorized these things.For Overall , my QM class is just a math class and we do not really discuss quantum physics, we only discuss the math for quantum physics, which no derivations are involve and we just memorize various mathematical concepts from linear algebra; Luckily for me, I took it upon myself to buy a really good QM text , that presents QM succintly at the undergrad level, but has the right amount of math needed to solve various QM problems at all ranges of difficulty. Bohm's Quantum theory is everything Peeble's textbook is not; Bohm's text discusses how various equations were derived, talks about many of the QM experiments that lead to establishing new physics concepts that characterize QM and the overall writing style is much clearer. How does your professor present QM to you? Is the presentation of QM generally clear or is it about as clear as a foggy car window and do you like the textbook that you use for your class?
