Nima Arkani-Hamed and Thomas Lam in Conversation

The Universe Speaks in Numbers - May 29, 2019
Physics and mathematics seem to be in a pre-established harmony, as Gottfried Leibniz observed long ago. New ideas generated by mathematical researchers have often proved to be essential to physicists trying to discover the most basic laws of nature. Likewise, physicists have often generated new insights into advanced mathematics. This event explores the astonishingly productive relationship between physics and mathematics and explores whether these disciplines might one day unify, perhaps leading to a giant structure that encompasses all the laws that describe the underlying workings of the universe.

Whenever Nima talks, we all win! He is a hero, a great entertainment, and an inspirational lecturer. One comes to wish that his name would be heralded by the public more than names like Tyson and Kaku that have less of an impact on the future (IMHO). Apologies to anyone this might offend.

[@witeporcelan]

I will only argue that Kaku is celebrated not only as cofounder of string theory, but also for his elegance in ability to communicate such complex aspects of the universe in simplest form to every day people. I pray he sticks around because his voice is like the physics version of Morgan Freeman lol

[@lucasthompson1650]

Unlike Tyson and Kaku, Nima is still working day-to-day on groundbreaking theoretical physics, he'll be a household name as soon as he gets a Nobel prize for something related to an emergent theory of spacetime, superunified dark matter theory, or providing us (humanity) with a deeper understanding of scattering amplitudes.

Nima always does a great job of explaining things in a clear and concise manner. Much appreciation from those of us who are a little slow. :)

[@pankajdey2053]

Nima, you are an inspiration to young research community irrespective of any field of science and engineering.

its amazing how much of this makes its way into music theory . im only an amateur in physics but music theory helps understand this stuff better its weird .

[@beenishmuazzam]

Such fine structure. Amazing

[@krzysztofdanel4475]

Nima is always excellent and I like very much watching and listening Him .

Awesome...

This looks like Fractal Information Theory (FIT)-Derived Geometric Musical Language (GML) which maps well to Holographic Boundary Conformal

Er, permutation at 8:44 is messed up, it's not bijective, RHS contains 3 twice :D

He emulates Roger Penrose

Penrose if he took a calligraphy class (just one) at his local library … but only because he was drunk and wandered in by accident.

I have a friend, Rhodes a scholar, who had him as his dissertation adviser.

[@lucasthompson1650]

@Chris Record That would be so cool … I can’t even imagine coming up with a topic interesting enough to discuss with him. Haha!
PS
A new paper, on “The Page curve of Hawking radiation”, was published by J. Maldacena and a few of his colleagues yesterday.
I saw that you were a fan in another comment, so thought I’d mention it in case you hadn’t seen it yet. Here’s the arXiv info:
arXiv:1908.10996 [hep-th]

Does amplituhedron or associahedron lead to tackling quantum complexity?

[@lucasthompson1650]

arXiv:1312.2007

[@BlueSoulTiger]

8:58 perhaps better?: a Permutation is a re-ordering of a bunch of symbols or elements of set (not necessarily numbers)

[@frun]

Nima always told amplituhedron is related to perturbative expansion. Does amplituhedron have a relationship to nonperturbative qft?

[@nadernader1937]

Does anyone know what these numbers at 5:33 slide represent, i.e., 12, 23, 34, etc?

[@jefferytoledo2505]

They're spinor brackets, contracted pairwise, and for the momenta of each numbered particle i.e. is the contraction of the the angled brackets corresponding to particles 1 and 2 (which respectively have momenta p1 and p2). The usual introduction for these Chapter 2 of arxiv.org/pdf/1308.1697.pdf .

[@naimulhaq9626]

Nima's connection between physics and mathematics seems promising, but explaining complexity, due to spin (BOHM) is better tackled by self-error correcting algorithm of quantum computing functions, if such an algorithm can be evolved. QC function may lead to a deeper insight into the boundary between micro and macro world and much more, like explaining consciousness, life, soul, time etc.
