    Wow. Difficult concepts rendered in pictures, particularly the Calabi-Yau quintic. Thank-you!

    Very Good pictorial framework of the subjects, teams are needed to collate just a few of the aspects.
    _____
    The essential themes of this presentation,(one of the best lectures, graphically), are intended to unify the concepts, such as the equivalence of the "One Electron" temporal superposition singularity objective vanishing point, and the hierarchical orbital of "vibrating strings" orthogonal and symmetrical to the same Quantum Operator Connection.
    Duality.., the infinite Unitarity of connection in quantized multiplicity of e-Pi-i superimposed modules/moduli of Spinfoam-Superspin Quantum Chemistry. The Universe is one objective connection of 1-0 Dimensional-Tangential existence, a modulation in principle, QM-TIMESPACE.

    Strings falling through the horizon (of an extremal black hole) is not a "flawed metaphor" for brane-string interaction, it's exactly the correct picture. This was what Witten used to understand holographic duality in the 90s.

    I admit it, it was Walter Bishops cow that drew me here...That and at 33:04, the quantum foam!Oh Boy! And at 36:04 quantum field theory, at least the theory which seems sensible to me, that space and time are emergent from the quantum gravity field, as well as the other 15 known quantum fields which together create the entire universe as we know it. The goal, writing the description that unifies all these things or GUT if you will in a language that is understandable in mathematics.Pieces of the puzzle are still out there, somewhere.

    @kurtpiket6739 7 лет назад +1

    I think it is amazing that inside quantum geometry there is not mentioned of what stuff intelligence, intellect, thinking, feeling and sening is made of. This is not a part of the periodic system!!!!!! Why not?????

      Because you are confused.
      Thinking and feeling are emergent processes; they are not themselves objects made of matter.

    And then what about astrology? people understood world is mathematical long before Newton. Even Newton comes from that. Only the model was not so accurate.
