    Norman J Wildberger is the greatest math teacher on the Net!

    Its interesting both from a historical, cultural as well as mathematical point of view. Your question is spot on: if high school maths teachers knew this history, then mathematics education would be not only deeper, but also much more interesting.

      Hi!, I hope you are still around, is there any decent source to know the details of eudoxus proof for the cone and pyramid?, he seems to have got some interesting geometric proofs but all the books that talk about it just gloss over it.

      Dr. Wildberger will help all he can. You may not ever understand how he knows so very much ,but you will find he can help you to understand more of what interest you. You never know enough about your own interest but then again you can rest assured he will put your feet into the right shoes if you work at it. He is the most beloved person because of his sincerity and dedication to teaching. Thankyou, Dr. Wildberger.

    I’m so glad someone is teaching that Archimedes developed calculus techniques, without delving into rigorous details about limits

    The spread polynomials have various formulas associated to them. See Chapter 8 of my book. As for the area of a 96-gon, that is essentially equivalent to finding the spread of 1/96 th of a circle. That requires an extension field of the rationals. In other words, the very existence of a 96-gon first must be carefully investigated. Number theory naturally enters here (although it is relatively simple number theory).

    Yes I suppose that would have been a very stratified society, with immensely rich elites and lots of impoverished slaves and peasants. No doubt life expectencies would vary dramatically been the different strata. And the great mathematicians/thinkers were generally part of, or at least close to, the elite, so could have comparable life spans to now.

    Very interesting series! I like learning about the great "prophets" of math. As a Canadian Prof. I thought somehow Tim Horton's should have been mentioned in one of the lectures.

    • @njwildberger
      @njwildberger  10 лет назад +5

      Perhaps Tim is now the most famous Canadian? I wasn't aware of his contribution to mathematics: but on second thought I think it was Erdos who said something like: `a mathematician is a machine that converts coffee into theorems.'

    Love these videos, but there was hardly anything about how the Greeks thought about infinity in it. Too bad, that's one of the reasons why I watched it. Most of the other stuff I already knew.
