I'm a math major and know a decent amount about which math texts would be good for which purpose. For instance, what you might want to read after multivariable calculus and linear algebra to get a taste of higher math, and then what you would want to read to dive in deeper etc. However, I'm next to clueless when it comes to physics. I've read Young and Freedman's "University Physics" and am taking an intro E&M course from the same text this Fall but between these basic first year courses and advanced physics...what is there? I see optics and termal physics and other seemingly tangential topics but nothing that bridges the gap between a course almost everyone takes and something interesting and challenging like quantum mechanics. Basically, can anyone suggest reading which would fill this void? Thanks in advance.
