Higgs Effective Field Theory (HEFT) has a geometric formulation as a curved manifold spanned by the Higgs degrees of freedom where physical observables are geometric invariants and the curvature depends on the scale of new physics. In this formulation the Standard Model Higgs.
How is it that the Higgs sector with its iconic Mexican Hat Potential…the most naively Geometric sector of the Standard Model of particle physics…is the only one which has zero obvious interest to differential geometry?

Spacetime is often tied to general relativity, but plays a very important role in particle physics as well:. - Antiparticles are a consequence of spacetime symmetries. - Spin is inherent to how quantum fields respect spacetime symmetries, not an added property. - Quantum.

The most common misconception is that is has something to do with general relativity. The Higgs boson is responsible for the masses of fundamental particles, general relativity is the theory of spacetime shaped by the energy and momentum, mass being just one part of that picture.
@martinmbauer What is most misunderstood about Higgs?.

Exactly right. Not only do physicists have secret committees dedicated to inventing the worst possible names, but it's an unwritten rule that even the Nobel Prize is awarded according to this principle. Which is why we lost it to AI last year.
@martinmbauer yeah why are physicists so godawful at naming things. to keep the info obfuscated?.

13 years ago today, the discovery of the Higgs boson, the central piece of the Standard Model, was announced!. What’s something you've always wanted to know about the Higgs boson? Ask away!

Is the tech industry rediscovering the advantages of diversity?.
For decades, leading universities have operated in a recruiting echo chamber, hiring faculty near exclusively from each other. The tech industry is now creating its own echo chamber for AI talent. In both cases, this inbreeding suffocates innovation and impedes genuine progress.

It would be much more interesting if it was moving slow.
This is pretty incredible. It seems like we've detected a *third ever* object entering our solar system from outside of it. It's moving FAST.

I thought they were all supposed to leave because of high taxes?.
Sweden and Norway - the two benchmarks for democratic socialism - have way more billionaires per capita than the United States. Why shouldn’t billionaires exist? . Almost every billionaire (that earned their wealth themselves - which is nearly all of them), became one by making

A 5 hour video on superconductivity and the Higgs mechanism by @RBehiel . Highly recommended! A true breath of fresh air in the constant flood of clickbait that is YouTube.
Are we living in a superconductor?. Short answer: basically, yes. Medium answer: empty space is not empty, but is actually pervaded by the Higgs field, which has a nonzero expectation value even in the vacuum of space, and is very much like a superconducting condensate. It’s so

If you use *only* data from galaxy surveys and the ΛCDM model, it predicts a cosmic microwave background with the power spectrum shown in red. When you go out and measure the background radiation you get the blue data. It's not circular, it's an extraordinary successful theory
@martinmbauer Seems circular. The CMB is amazingly compliant with a fitted theory, so contamination can’t be there? . Apologies if I misunderstood.

At no point does this paper claim that "the 'Cosmic Microwave Background Radiation' can be explained entirely by the energy of recently discovered Early Mature Galaxies". What it actually suggests is that these galaxies might contribute a non-negligible contamination to the.
Ahahahaha, the James Webb Space Telescope continues to deliver massive L’s for astrophysics. A new paper shows that the “Cosmic Microwave Background Radiation” can be explained entirely by the energy of recently discovered Early Mature Galaxies — massive galaxies that the JWST

Beautiful!.
@martinmbauer Same mechanism of action for why old sports photos have a blue tint! Rayleigh scattering due to the cigarette smoke. The smoke by itself is simply white, but when mixed with vapor from the lungs it scatters like atmospheric water

Ok, what are we going to do if it begins morsing prime numbers?.
🍄 🤔 Engineers from the UK have "taught" mushrooms to play musical instruments Everything works due to special sensors that read electrical impulses in the caps, and then turn into commands for motors.
