I'm looking for good books to give me some more "taste" on beautiful aspects of QM. I'm actually studying for my undergraduate exam on the 27th november that comes in a strong academic flavour and would love a relaxed but deep reading. For example i totally loved Robbins's "What is mathematics?" while studying for my calculus exam or some stuff from Needham's "Visual Complex Analysis" while studying, oh yep, complex analysis :P. I liked how both author guided me through arguments i already studied, eventually pointing out beautiful things one may eventually ignore while worrying to learn "doing" things. Robbins's paragraph about fundamental theorem of calculus is a huge example at my eyes. I do appreciate but am not really a big fan of Feynman's lectures. Let me know and pardon the bad english, that's not my first language!
