CERN announced today that it is continuing with preliminary plans for a new collider (the FCC) that would be much larger than the LHC. Unsurprisingly, people are now arguing about this online. This is a famously productive activity, so I thought I would join in! 1/n

For the mathy readers, a nice article on transitive Courant algebroids and string structures [maths.adelaide.edu.au/pedram.hekmati…] with a number of proofs. Maybe the subject of this weeks blog :) There is even a section on heterotic algebroids, with a small subsection on Atiyah algebroids :)

Extraordinarily creative physicist John Wheeler (born on this date in 1911) loved to fill blackboards with colorful diagrams, such as black hole schematics, and explain each picture one by one, from left to right

String Math conferences are an important event of the year for anyone working at the interface between mathematics and theoretical physics. In 2020, String Math comes to South Africa, hosted on Zoom & live-streamed to Youtube. Registration is now open 👇 indico.cern.ch/event/938492/o…

Preparing to teach a new cosmology course (this time to students in Amsterdam and Taiwan simultaneously). Are there good resources on online teaching? Any opinions on pre-recorded vs live lectures? (A video system has been set up here, so I can use a blackboard

Dake vs. Nolf 😤 tomorrow Let us hear your predictions! Presented by Tezos

Here’s a blog post on my exciting (at least to me) new result that I think is potentially important for quantum gravity. It is about a new kind of distribution, pertaining to the ground states of a universal part of many black hole systems. asymptotia.com/2022/06/24/a-n… 1/2

Carol Davis typed my PhD thesis in 1980! "I don't have to type theses anymore. The students do their own, which is so much easier. Although I miss the money that I used to make from typing them, I’m so happy that I get to see spring. I never did back in the day."

As John Bell pointed out, when the #Queen of England dies, the speed of light limit will be broken.

H -> γ Z is finally here!

If I did the counting correctly then at my university there are about 80 profs in total doing research in philosophy & religion, but 5 profs in total in theoretical/math physics. Yet, who is blamed for working on things with no obvious direct measurable/technological impact? 1/4

Absolute nonsense. The Standard Model makes no prediction about the emergence of consciousness *at all*

Oh nice, i found an introduction to tensor calculus on arxiv by Taha Sochi.
