5 days ago · In terms of mortality, the last year or two at the Columbia math department have been grim ones, as we’ve lost five senior faculty at relatively young ages: Igor Krichever at age 72, Henry Pinkham at age 74, Lars Nielsen at age 70, Walter Neumann just last week at age 78, and now Hamilton at age 81.
Slides from introductory talks on quantum mechanics and representation theory at LaGuardia Community College, November 1, 2017 and Queensborough Community College, November 15, 2017. Slides from a colloquium talk in the physics and astronomy department at Rochester, March 7, 2018.
Sep 26, 2024 · Posted on August 13, 2024 by woit. Two more items: I can’t recommend strongly enough that you watch the new Curt Jaimungal podcast with Edward Frenkel. The nominal topic is the recent proof of the geometric Langlands conjecture, but this is introductory material, with geometric Langlands and …. Continue reading →.

Oct 20, 2022 · Euclidean Twistor Unification. 10/20/22. This is work in progress towards creating a theory unifying the standard model and gravitation, based on the idea of defining the theory on the Euclidean signature version of twistor space.
Jul 28, 2023 · Strings 2023. Posted on July 28, 2023 by woit. For much of the past week, I’ve been attending off and on (on Zoom) the Strings 2023 conference. This year it’s in a hybrid format, with 200 participants in person at the Perimeter Institute, and another 1200 or so on Zoom.
Jul 29, 2022 · Posted on July 29, 2022 by woit. There’s a new book out this month, Before the Big Bang: The Origin of the Universe from the Multiverse, about which we’re told: One of the world’s most celebrated cosmologists presents her breakthrough explanation of our origins in the multiverse.
Nov 30, 2022 · The theory tested at the Google lab “only has a very tangential relationship to any possible theories of quantum gravity in our Universe”, says Peter Shor, a mathematician at the Massachusetts Institute of Technology in Cambridge.
Feb 28, 2024 · I will review this and describe a new approach using the trace formua as well as some analytic arguments reminiscent of those used in the classical case. In more concrete terms the problem is to prove general modularity theorems, and I will explain the progress I have made on this problem.
Feb 7, 2024 · Woit is using spinors and twistors to create what he hopes are the foundations of a theory of everything. He describes space and time using vectors, which are mathematical instructions for how to move between two points in space and time – that are the product of two spinors.
