    When I saw this lecture in my suggested videos, I thought: Why on earth wants Google me to watch such an advanced topic, when I usually only watch 3blue1brown, mathologer and numberphile? But then I reached the climax of this lecture: a unification of quantum theory and general relativity. Bravo algorithm! Didn’t see that one coming. By the way: fantastic talk.

    Great presentation, terrible use of camera This isn't the kind of event where I need to "add interest" by occasionally viewing the audience while sacrificing the information conveyed on the board. That should always remain visible. I saw this happen sometimes for when a talk shows proprietary stuff not freed for displaying on the internet, but that doesn't seem to be the case here. Somebody just decided that this is how it's done, so we constantly pop away from the slides.

    Professor Hubbard brought a gorgeous explication to the Mandelbrot set. Fractal scalar recursions appear with such ubiquity in the world’s imagery and visual exuberance, they are made even more interesting with some understanding of the discursive mathematics by which they happen. The Mandelbrot is a great complement of cosmic design when paired with the esthetics of the Fibonacci series. Borrowing Professor Hubbard’s eloquent homage to simplicity as the mother of complexity, I find the generative mathematics of the Golden Ratio, derived from Fibonacci’s {1, 1, 2, 3, 5, 8, 13 . . . } sequence of procursive approximation, a little more compelling, but equally gymnastic with Mandelbrot in the patterns of nature so endearing to H. sapiens. Here we are, 40,000 years on, still endlessly fascinated with seashells and shorelines, entranced with the beauty of spirals and riveted to the grace of symmetry, irregular or exact. Look there-over that dune, a pair of old friends, Fibonacci and Mandelbrot, strolling along the very beach where Newton looked for shiny pebbles, and where, a century and one-half later, Darwin gazed out, not on the spirals of shells, but on the oceans of eons that finally launched his own inklings. The random but meaningful, inanimate but eloquent, lines and shapes and dimensions of the world are just cause for pleasure and wonder, until we assign ciphers, or numbers, to them, paradoxically clarifying their relationships and our understanding of their function. They are even insinuated throughout our thinking, navigating and evolving, such that they allow us to reciprocally insinuate ourselves into fractals, meta-reflexively compounding our abstraction of nature through numbers by anthropomorphizing numbered abstraction for use as tools, art, conceptual aids and literary devices. We are semiotically harboring, anchoring and even launching our understanding of nature into the real-time, brick-and-mortar natural world. The world made us who we are and now we think we are the world. Our fate now is in our numbers, not in our stars, but in our understanding of stars. Go figure. And that is the sound of one recursion, branching in a spiral mirror. Who knew?

    'All 3-manifolds can be built using just 8 geometries, is a beautiful realization of Ramanujan's magic number 24=3x8, that led him to count all the photons in the whole universe(partition function) given to him by Goddess Namagiri [Vishnu's consort]). There is unity of Poincare's conjecture, Fermat's last theorem, geometrization theorem and modularity theorem. They all are perfectly expressed by Perelman's solution. Beautifully expressed/demonstrated by the speaker by the hyperbolic geometry. Perelman is a singular mind of modern science, like Ramanujan.
