I’m very grateful to mathematician Hugh Woodin, Professor of Philosophy and Mathematics at Harvard, for taking the time on multiple occasions to discuss this topic with me and help me wrap my (finite) head around it.

I’m also grateful to David Eisenbud, the Director of the Mathematical Sciences Research Institute (MSRI) and professor of mathematics at the University of California, Berkeley, for his help and for connecting me with Hugh Woodin.

And of course, big thanks to Brady Haran who created the “mile of pi” seen in this video and connected me with all these mathematicians in the first place. His channel, Numberphile, is superb:

    what about infinite^2

    that feeling after u finish this kind of videos ????

  3. Rocky Scape says:

    People are creating or chasing an end that never ends, and we don’t accept
    it until we see proof or an end, but for infinity there is none, its just a
    flaw in the number system, think you found the end? Just add 1 to it.

    You pronounce alef wrong

    on 1 and 2 you mist 21

    Not sure if his videos make me smarter or if each video makes my brain
    closer to exploding.

    i didnt understand this one even more than i usually dont understand these

  8. AlarmClock65 says:

    This is one of your best videos yet. You explain everything perfectly
    without dumbing anything down and just make it so fascinating. And as
    always, thanks for filming.

    This is great because I’ll finally have a comeback next time my girlfriend
    says she loves me times infinity

    This video triggers me.

    For those who havent watched the video yet and is looking at comments…..

    infinity one…
    infinity two…
    infinity three…

    My brain is smoking.

    Now, I believe that mathematicians are mad with boredom

  16. Golden Hair says:

    The Continuum Hypothesis (CH) was shown by Gödel to be consistent with set
    theory (with or without axiom of choice (AC)). Later, Paul Cohen showed
    the negation of the CH to be consistent with set theory (with or without
    AC). So CH can be taken as an axiom. Or not. Your choice. You get then
    to develop the consequences and see if like them. Or not.

    what about the Grahams Number?

  18. ruza esp says:

    omega + infinity?

  19. GoErikTheRed says:

    Graham’s number remains the largest number used constructively in a proof.
