The Gaussian Moments Conjecture is a pretty conjecture connected to probability and quantum field theory. Two days ago we suddenly learned it's false! - since it implies the Jacobian conjecture. Let me explain this conjecture - it's pretty simple as these things go. (1/n)

The Gaussian Moments Conjecture and the Jacobian Conjecture

We first propose what we call the Gaussian Moments Conjecture. We then show that the Jacobian Conjecture follows from the Gaussian Moments Conjecture. We also give a counter-example to a more general ...

Oxford drinkers may finally be able to swear in the Three Goats’ Heads after the death of Humphrey Smith, the irascible owner of Sam Smiths Brewery, at the age of 81. The pub chain enforced strict bans on swearing and mobile phone use. Smith was described in a Facebook pubs group as “an absolute tit

Lesser-known-fact: the summer #solstice is a moment in time that delivers the longest day/shortest night in the North. At 9:24am (BST) the North Pole will be at its most-tilted towards the Sun. Me & the druids will be on #BBCR4 Broadcasting House later on to celebrate 🤗🔭🧪 📷: National Maritime Museum

The main diagram shows the Earth's annual rotation around the Sun, surrounded by a zodiacal scale that gives the names, symbols and images of the signs of the zodiac. The seasons and the positions of the equinoxes and solstices are marked. Text at the corners describes the Zodiac and the Earth, and a longer text at the bottom explains the Phenomena of the Seasons.

Happy Summer Solstice (for the Northern Hemisphere). #nights_drawing_in 🙂

Interesting graph from this Robert Armstrong article in the FT, showing the predicted cash flow payback of AI investment for the big four. I’m wondering: where’s the extra money coming from? Their cloud businesses? How is Meta going to make more money? www.ft.com/content/b31f...

Apart from careerism, I think that part of the story here is our core scientific dogma that big robust phenomena exist and it’s our job to uncover them. Once you’ve bought into that it’s not too difficult to start selecting the data that show the sought-for effect in the cleanest way

I wonder what an alternative history where GR was not discovered by Einstein would have looked like. Would GPS have been the experimental puzzle that birthed it?

A general unease about the study of large deviations in physics: The original LD function is entropy. By sharing energy between two subsystems one can end up in an unlikely state of one system by maximising the likelihood of the composite system…
