    I want to help Physics education. What should I do?

    For mathematics. Or at least of the pure math type. I do not think there is a better alternative to the chalk method. It can be improved if thr lecture is recorded as well. I do have a problem with pure math classes. Oftentimes a whole lecture can be devoted to proving a big theorem. But rarely...

    Other Complex analysis or calculus?

    I found schaums useful for things like probability [Markov Chains], PDE, Toplogy, complex analysis Ie., for more examples to apply the theory learned from pure mathbooks.

    Undergrad How do E[X] and E[|X|] relate?

    Thank you fact checker! I now understand that the proof given was using the measure theory [lebesgue integral] formulation of probability. the decomposition of E into its positive and negative parts comfirmed my hunch. from my understanding, E[|X|] exists iff E[X] does using lebesgue...

    Undergrad How do E[X] and E[|X|] relate?

    Greetings, I am studying probability theory [non-measure theory] from a textbook. I stumbled to the topic stating that Cauchy Distribution has no moments. It was not proved, and I tried working it via direct calculation of the improper integral of E[X^n] for the case n=1. Anyhow, I wanted...

    Other Complex analysis or calculus?

    CAlculus is typically learned before complex... So calculus.

    Foundations A rigorous approach to learn Mathematics

    I would suggest getting a copy of Hammock : Book of Proofs Pommersheim: A Lively Introduction to the theory of numbers Gallian: Contemporary Algebra Abbot: Understanding Analysis Moise/Downs: Geometry Work through the proofs book together with the number theory and geometry book. Once you...

    Other What are some good books for learning Galois Theory?

    I may be wrong. Its been a while since I learned the basics. I believe a member on this forum, Mathwonk, wrote some notes explaining Galois Theory first and filling in the blanks. I can be wrong. In anycase, check out his algebra notes. If you want something easier but well written, to get...

    Number Theory Suggestions for Analytic Number Theory textbooks

    I found this book excellent to get the basics down. Do you just find it as a boring read, or terse?

    Intro Math Hassani's books on Mathematical Physics/Methods

    Geez. The hardcover is pricey. BUt it is quality. A friend of myne owns a copy and I skimmed through it. Lots of cool stuff. Will buy a paperback soon. i think the op is better served by Boas due to background information listed. Having a pure math background. The section on tensors was gold...

    Intro Physics Physics Introduction book

    If you can find a copy of Alonso and Finn Physics at the library. Its a great book but expensive. I would supplement the class book with this one. If you can find Alonso and Finn: Fundamental University Physics Volume 1, which is even better but more harder to find. Than use that one in...
