    Undergrad My basic understanding of set theory

    I would read chapter 1, then flip to the last chapter. It will walk you through. https://richardhammack.github.io/BookOfProof/Main.pdf The book above is open source.

    Studying Interested in Astronomy as a Freshman

    I think anything is possible, within reason, if you put in the work. I dropped out during 9th grade, never receiving more than a C from K-12. Fast forward, got my GED at 21, and went to CC at 23. Decided to major in mathematis since I did not like writing papers, and chose the major with the...

    Advice for Physics Olympiads

    I know that students who partake in the physics olympiads have gone through Irodov. Maybe even Kleppner and Kolenkow as well.

    Pre-reqs for Ultrafast Optics? (Jackson or Zangwill for Electrodynamics?)

    I cant help you directly. As I majored in Math (MS). However, I was 4 classes short from a physics degree in undergrad. I found the book by Schwartz: Principles Of Electrodynamics to be a step up from Ohanians book. Where I much prefered Ohaniam to Griffiths. My friend studies physics at the...

    Announcement RIP Vanadium 50

    I wonder if Ms Vanadium also received her fair share of sass lol. I would have snipped him!! I liked seeing his replies. Reminded me of a drill seargent or an old gunslinger (my grandfather was one). Always got a chuckle. He was well informed, even at his old age. Something to strive for.

    Physics Need some advice! (making a physics YouTube channel)

    I know someone who is very succesful in youtube/tiktok although. Not an educational channel. They bring in roughly 150k a year. What they told me, was that todays generation has "tik tok" brain. So playing with short and long format videos. Would be something to consider.

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

    THey also lived in age in which information advanced more slowly. Unless someone solves something crazy like navier-stokes , Reimann Hypothesis. Then the importance discoveries have the probability may not fully be appreciated instantly... It would be interesting, and I am a bit too lazy. To...

    ChatGPT Examples, Good and Bad

    Is there any difference in the answers it outputs using the free and "premium" version?

    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.
