The year is 2026. The world has ended and you're the only person left. But you don't know it because you spend all day inside, posting on Facebook, where you interact with bots agreeing with each other on how bad a movie was that none of you ever saw.

Remembering with @stevenlowette.bsky.social the "realistic conference programme adjustments" made to theory talks at the ICHEP conference after the lack of a 750 GeV signal confirmation by ATLAS and CMS. Chicago 2016.

"It seems to be a lesson of history that the commonplace may be understood as a reduction of the exceptional, but the exceptional cannot be understood as an amplification of the commonplace.” — Edgar Wind (1967)

Um, let me help you. Every single lecture is carefully planned, advertised ahead of time, and delivered according to the schedule. Which is the opposite of 'random'. You are welcome. 😊

A square wave can be expressed as the infinite sum of odd sine waves with ever-decreasing amplitudes and periods. This is an example of a Fourier transform, a powerful tool in maths & physics that can be used for encoding/decoding information stored in waves. 1/2

That's some serious beef there between Cabibbo and Gell-Mann.

"20 years ago, I used to find the anthropic interpretation of the universe upsetting, in part bc of the difficulty it might present in understanding physics. Over the years I have mellowed. I suppose I reluctantly came to accept the universe was not created for our convenience in understanding it."

A bit of a specialised paper title, but definitely a very accessible abstract.

I have seen on my timeline posts about hypothesis-testing and Type-I/Type-II errors. I would like to contribute a figure from my lecture notes to the public discussion.

"Keep strong, if possible. In any case, keep cool. Have unlimited patience. Never corner an opponent, and always assist him to save face. Put yourself in his shoes - so as to see things through his eyes. Avoid self-righteousness like the devil - nothing is so self-blinding." B.H. Liddell Hart

We're delighted to share the news that Elena Villhauer has passed her PhD viva for her thesis on 'Defying 4D Gravity: Novel Searches for Signatures of String Theory via Non-minimal Dark Sectors, Scalar Cascades, Non-Commutative Black Holes, and Deep Learning'. Congratulations Elena!

One of the great things about the new platform: you don't have Elon Musk's tweets popping up out of nowhere, all the time, for no reason whatsoever.
