    At 0:04 is that Gromov, Atiyah, Bill Thurston, and Cedric Villani? I'm probs wrong, but if that's right this is crazy.

      You're right. Steven smale is in the front row too.

      Louis Nirenberg is in the front row too, and Robert Bryant next to Atiyah.

      It seems you would lose your mind if you saw Socrates and Plato together. Oh ... wait a second ...

      First row - Gabai, Thurston, Nirenberg, Smale
      Second row - Atiyah, Bryant
      That's all I could identify. I am sure others can add.

      Why would it be crazy that in a tiny community the most esteemed members would be invited to the esteemed persons conference?

    This is only just begining:
    I can’t immediately tell if this is
    C*C = (C) * (C)
    or
    R^4 = (R^3) * (R)
    Neither of which has to do with what this is probably talking about, which is the technically 4 dimensional TM = 2 + 2 in a way that’s over the real as it were but is sincerely different than what can be topologically deduced is the natural implication of the previous demonstrations of explicit geometry.
    An exact comparison must be given to this kind of thing

      He's talking about the fact that the alternating group of degree n >= 3 is non-simple if and only if n = 4. en.wikipedia.org/wiki/Alternating_group
