@FlutterCarl Got stuck at airport - I prlmise to check over weekend ok?

@sentefmi I have the answer potentially coming this afternoon.. will you take 5 minutes to review when I publish?

I’m genuinely thrilled. There are rare moments in science when two long-standing puzzles suddenly seem to click into place at once. For me, this feels like one of them: the possibility that we may be seeing a common thread between high-T superconductivity and light-induced SC.

@skdh @WilmsRolf I like it better. (Mond) we have a ton of scale dependent power laws in nature

@WilmsRolf Well if you think that MOND is correct, then there isn't any dark matter at all!

Researchers from the University of Bonn in Germany have re-analysed observations of galaxy clusters and argue that much of the clusters’ “missing” mass may not be exotic dark matter but ordinary matter in the form of faint stellar remnants. Galaxy clusters have long required about five times more mass than what is visible to explain the observed galaxy motions, an observation that is usually attributed to dark matter. But the authors combined gravitational lensing, X-ray, and optical data with models of star formation and found that the total mass in stars and their remnants could be almost twice as high as previously estimated. This matters because Modified Newtonian Dynamics (MOND), an alternative to dark matter, seems to not work well for galaxy clusters. The discrepancy between the MOND predictions and the observations from galaxy clusters almost goes away with the new estimate, while dark matter no longer works all that well.

@skdh I think dark matter may turn out to be a myth just like dark energy

@FlutterCarl Sure

@Rand_Simberg @Andercot Wait for our paper

@sentefmi @Andercot OK, hope you're right.

why don't we have famous physicists anymore?

@Rand_Simberg @Andercot Wait

@Andercot Two reasons: String theory No one has recently come up with new theories that revolutionize technology in the way past physicists did.

@ThomasVanRiet2 Would be fine by me

Conjecture: by next fall most theoretical physicists will mainly use paid AI services to solve their research problems.

perturb it. If this picture is right, then light is not just a probe. It is a tool to access hidden routes toward superconductivity.

far from equilibrium. What excites me most is the emerging idea that these are not separate mysteries, but perhaps two faces of the same deeper physics: strong fluctuations, collective modes, and the possibility that light can reshape the landscape of pairing rather than merely

@InnaVishik Elegantly for the same reason that we now understand the PG/SYK/normal phase we also understand how metastable SC becomes stabilized

@InnaVishik They do finally -- I think I solved it

Never say that the mechanism of cuprate high temperature superconductivity is unknown, because every theorist and half the experimentalists “know” the mechanism. Unfortunately, their choice explanations do not agree with each other or with a plurality of the data.

Deniz Undav this season ⚽️ 20 goals 🅰️ 12 assists One of the best players in the world this season and Germany‘s best striker. Give him the love and respect he deserves ‼️

@Prof_Buehler Prömel dringend gebraucht

Die Spieler von Porto liegen in der 1. Halbzeit netto 15 Minuten auf dem Rasen und es gibt lächerliche 4 Minuten Nachspielzeit. An der Bank werden Linienrichter und 4. Offizieller ständig von irgendeinem bearbeitet ohne dass was passiert. So geht K.O.-Phase im Europapokal. #VfB

@TheZvi If only they used units, then one could at least catch the ones with the wrong formula. But yes-- picking 6 is hilarious.

My son is asked to find surface area of a cube for his homework. There is exactly one wrong side length for such a problem, and they picked it.

Steven Weinberg always had excellent advice for everyone not just for young physicists.

@martinmbauer What they actually mean is that once AI is sufficiently advanced, people like them (AI tech bros) will be out of a job because their superficial Blabla has been debunked as nonsense gibberish. Can already witness it now.

Yep, math is going to be 'solved' in a few years everyone Is there some kind of bet going on where everyone is trying to post the most unhinged opinion about physics and math at the moment?

@DanielWhiteson @InnaVishik Funny. Not even a single branch of physics works like this. And different branches work differently. It is more diverse than some people can even imagine. But the worst thing is that computer scientists (or whatever they are) are explaining to us how physics works.

What do these people think "physics" is? Do they imagine it's a finite list of unsolved hard physics problems, the ultimate homework set? Do they think if an LLM solves them, we'll shrug and say "that's it, we have no more curiosity. physics is done" ????

@chrizz1893 @Bart1893 Zuhause gegen Freiburg war kein Glück. Zuhause gegen Mainz auch nicht. Auswärts Köln auch nicht, auch nicht gegen Augsburg. In Dortmund noch eher. Heute ja. Zuhause gegen Gladbach war Glück.

@sentefmi @Bart1893 Zu Hause Augsburg, auswärts Köln, zu Hause Mainz und Freiburg … spielgerechter Tabellenstand

Heute hätte man zum Ausgleich einiger Pechspiele einmal unverdient was holen können. Dann wieder sowas. Das unsortierte Gegentor passt zur schlechtem Defensivleistung. #VfB #M05VFB
