Feb 7, 2015 · Posted on February 6, 2015 by woit. I recently heard from Hirosi Ooguri that a transcript of a long conversation with Witten held at the time of his Kyoto Prize award has just appeared in the Kavli IPMU Newsletter. It’s a truly fascinating document, giving some great insights into Witten’s work at the boundary of math and physics and how he ...

It is extremely important to probe the twin mysteries of the cosmic acceleration and the smallness of the electroweak scale as thoroughly as possible, in order to determine whether we are interpreting the facts correctly and possibly to discover a new layer of structure. In the case of the cosmic acceleration, this means measuring as precisely as w...
If it is eventually possible to go to higher energies, I can imagine several possible outcomes. It might become rather clear that the traditional idea of naturalness is not the whole story and that we have on our hands a “bare” Higgs particle, without a mechanism that would account for its mass scale. Alternatively, we might find out that the appar...
There are multiple places that new clues could come from. The possible anomalies in b physics observed at CERN are extremely significant if they hold up. The search for an electric dipole moment of the electron or neutron is also very important and could possibly give a signal of something new happening at energies close to those that we have alrea...
The new ideas about gravity and quantum mechanics that go under the rough title “It from qubit” are really exciting. Black-hole thermodynamics was discovered in the 1970s through the work of Jacob Bekenstein, Stephen Hawking and others. These results were fascinating, but for several decades it seemed to me – rightly or wrongly – that this field wa...
It is really hard to exaggerate how the field has changed. I started graduate school at Princeton in September 1973. Asymptotic freedom of non-abelian gauge theory had just been discovered a few months earlier by David Gross, Frank Wilzcek and David Politzer. This was the last key ingredient that was needed to make possible the SM as we know it tod...
Jun 2, 2018 · For example, Wikipedia claims that . Witten's work [on Chern-Simons theory and topological quantum field theory] was based on the mathematically ill-defined notion of a Feynman path integral and was therefore not mathematically rigorous, [although] mathematicians were [later] able to systematically develop Witten's ideas.
May 2, 2019 · Witten Interview. Posted on May 2, 2019 by woit. Graham Farmelo has posted a very interesting interview he did with Witten last year, as part of his promotion of his forthcoming book The Universe Speaks in Numbers. One surprising thing I learned from the interview is that Witten learned Calculus when he was 11 (this would have been 1962).

Dec 22, 2021 · Dear Peter, as regards Witten’s interview, there might be some other reasons why the “multiverse mania” is no more the main center of discussion … when questioned about “Which current developments in theory are you most excited about?”, Witten clearly stated that the “It From Qbit” ideas connecting gravity and quantum theory, via the insight from “holographic duality” on ...
