These fucking people...

(Such a shame that people like Deutsch agrees to give a mantle of credibility to this lazy bullshit... Gpt-8? Explaining quantum gravity? Jeeez)

I'm feeling breathless, all the most deranged features of our society coalescing around the genocide unfolding in Gaza, and these fu***ng people talk about "real estate gold mines".

Infuriating and deeply terrifying, which (I guess) is one of their point.

I should not speak for the Lord himself, but I'm quite sure he would disgusted by these people, like Old Testament obliterating rage.

People like @parismarx.com and @edzitron.com often talk about how Big Tech is desperate in the search of the "Next Big Thing". At Google, the press release about their Willow quantum chip came right after this sobering comment by Sundar Pichai.

There's a deluded economist for every bad policy. But the idea to let AI evaluate scientific proposals speaks at how little these people know about how real world (i.e. outside their crackpot foundations) works.

Here we show the angular momentum exchange at long time scales. For L >= 5 (i.e. fast enough impurities), the channel closes fast, while slower impurities (L < 5) keeps exchanging for a prolonged times, and revivals (those wide peaks) are observed. Check the paper for a detailed discussion!

This is a prime example of what physicists call a quasiparticle: a concept where the intrinsic properties of an object are altered by its interaction with the surrounding environment. After all, a horse running through the desert behaves quite differently from one galloping in a vacuum!

For a touch of cosmic horror, think about the 303-j symbol, taking more than 2 years to be computed. Obviously this can truly hinders our understanding of rotations when bodies are immersed in a many-body environment. So we have to be smart about it.

When n = 1, we’re coupling two angular momenta; for n = 2, it’s three, and so on... However, for a many body system, we quickly descend into algebraic hell: notice the log-scale below, with exotic coefficients exponentially difficult to compute.

In the quantum realm, things get even more fascinating. On one hand, the mathematical formulation of quantized angular momentum (the propensity to rotate) was relatively quickly established in the 1950s by towering figures like Eugene Wigner and Giulio Racah.

Mi sa che la domanda ormai dovrebbe essere: chi e cosa resta della striscia di Gaza?
