    Graduate Proving Existence of an Element in a Non-Empty Subset of Natural Numbers

    I'm a little bit stuck on this problem myself. I understand the above proof, but I don't want to use the comparability result of the following section. I'm thinking that since E is nonempty, we can take the intersection of E to establish a minimal element in E... But I am not able to complete...

    Other Should I Become a Mathematician?

    I'd personally do the Lang/Kiselev list. Be sure to check out some of the other "theory" books on the first link a gave you. Particularly the ones on inequalities.

    Other Should I Become a Mathematician?

    I've had instructors who say "truth sets" so I don't think that aspect is necessarily outdated... I'm sure they would still make fine books (I've only read a little), but that's if you can stand the typewriter typesetting. Here are some other "lists" for you...

    How Can I Pursue Post-Bac Physics in LA Without a Second Bachelor's Degree?

    No, it's all through the community college. You have to get cross enrollment paperwork straightened out with the CC registrar office (easy... you just have to get them to do it!). Then you crash the UC class on the first day, get the professor's permission (they sign the paperwork), and then you...

    How Can I Pursue Post-Bac Physics in LA Without a Second Bachelor's Degree?

    If you want to take UC classes (and get credit), you should consider enrolling in a community college. Most UCs allow community college students to cross-enroll if they are enrolled for 6 or more units at their community college. I can only speak for UCSD, but the fee was only ~$100 and I could...

    Yeah I was confused about my post too!

    Classical Electricity and Magnetism by Edward Purcell

    They do not include the texts (unless the text is free as I believe some of Strang's books are for his math courses). I accidentally included the Kleppner comment above by accident (I forgot which thread I was responding to), but there is also an international edition for Purcell that can be had...

    Classical Electricity and Magnetism by Edward Purcell

    FYI there is an international edition for Kleppner. I found it for less than $10 at a used book store. @QuantumCurt: MIT ocw has a course on SR that can be taken after a freshman physics course. Here is the syllabus (with books)...

    Post Your Summer/Fall 2013 Class Schedules

    I took them simultaneously and I see no reason to take multivariable calc before diff eq. I recommend linear algebra before multivariable calc and diff eq, though. @Walk_w/o_aim: Hopefully I'll get the opportunity next year. Good luck on the Putnam and enjoy the class!

    Are Commutative Algebra and Algebraic Geometry useful for physics?

    I'm sure it depends on what you are interested in (physics-wise). A couple of my instructors last year do research in mathematical physics and are algebraic geometers. I know group theory is useful for at least some people studying physics.

    I really wanted to take my schools Putnam-prep course, but it conflicts with my analysis class :'-(
