Researchers report the first measurements of quantum entanglement between two massive vector bosons at the electroweak scale. Using Higgs-boson decays at the LHC, they find strong evidence for entanglement between the spins of two Z bosons. The Letter: go.aps.org/4yBoqUo

unfortunately i contacted them on the night of wednesday, september 2nd making the following points 1. i had intel they had information about math work i was doing and a few days before they had spun up a group to try to compete. 2. i emphasized and reemphasized mine was a strictly personal mathematical collaboration 3. that this was a collaboration that had been going on for a year 4. that in my personal collaboration we were happy users of codex as well as obviously claude (and i later complimented astra explicitly after it came out for its help, and reassured i would obviously be sprinkling acknowledgments for it, previous models, and codex liberally in the writeups) 5. that it would look terrible if openai were competing against mathematician consumers, and my collaborator (Tristan) wanted to email about this explicitly 6. that i expected none but in the worst case intended to refuse marketing around the result we were working towards, being the fruit of a personal external academic collaboration, and wanted to express this because i figured worries about such marketing by their leadership was why a team was spun up to extraordinarily directly compete. sebastien and i have in the past months had our fun pushing each other on twitter, but as i process it all i keep feeling bad about Tristan. 1. neither of us could sleep Sunday night, so we went on a walk around the city. i finally asked him why fluids, and he told me it was the navier-stokes problem. he told me parts of the story about his classic nonuniqueness result with Vicol i hadn’t heard yet, and also about how he too grew up writing shaders as a kid and then switched to math 2. tristan is a mathematician’s mathematician. he kept rock solid to his principles during the tense calls and negotiations, immediately turning down a career dream and million dollar prize for me, the sort of strange excited unclear-quasiuseful confused idiot in our collaboration. fifteen minutes later, his feet were up on his desk with three toes per foot peeking out of ripped socks 3. our periodic call after i’d texted him euler blowup was just laughing for an hour or two. just laughing. i’d seen fable deal correctly with monge ampere in the equality case of ehrhart’s conjecture, so in some call before that i’d really pushed him for the craziest shit he could think of that i might try. i texted him the pdf as an update on that “diego luis 3” line, in which following his incredible expression of intuition i hodgepodge slapped together a bunch of our recent work, in particular correcting a bunch of better and lesser known papers in the literature, as well as on diego and luis’ ipm paper, and hoped an analogous construction for boussinesq (thus axisym euler) might work out. i managed to wade through enough confusion to insist to the model it stop telling me stupid regularity stuff about kelvin waves, and a rayleigh-taylor ansatz stuck. like i said, just laughing. when i texted him the pdf, the worst thing either of us had seen so far, i didn’t even comment on the euler blowup claim, only explaining why skepticism should remain for boussinesq, because i found it so shocking. i mean what the hell did i know, i must’ve confused myself by misunderstanding one adjective like i was used to with algebraic geometry. im so lucky to have been able to live that 4. he managed all this this entire time with unclear sleep, timestamps continue to amaze me, due to just recently having a kid it is obvious he deserves the same sort of praise he heaped upon luis, perhaps mutatis mutandis:)

nothing at all was locked we were just willing to talk but you didn't talk to us ... sorry but that's just untrue, we were willing to go above and beyond and have as many discussions as you would have liked to reach resolution.

for those like me who need a @3blue1brown video to understand what this means say thanks to fable
hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final ((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

Yapay zekâ çağında fizik öğrenmenin değeri azalıyor mu? İnsanların fizik öğrenmesi, "Newton'un üç yasasını ezberlemek" demek değil. Fizik bir bilgi yığını değil; gerçeklikle ilişki kurmanın yolu, bir düşünme biçimidir. Oppenheimer filminde geçmeyen bir örnek. Enrico Fermi, Trinity testinde bomba patlarken elinden birkaç kâğıt parçası bıraktı ve basınç dalgasının onları ne kadar savurduğuna bakarak patlamanın enerjisini kabaca tahmin etti, hem de devasa ölçüm cihazlarından çok önce. Fiziğin asıl kazandırdığı budur. Hiçbir veritabanında olmayan bir soruyla karşılaşınca "hangi büyüklük önemli, bu sayı mantıklı mı?" diye düşünebilmek. Fizik insanı kandırılmaya karşı da korur. Hem YZ'ye hem de insana karşı. Biri sana "telefonu 5 saniyede şarj eden cihaz" ya da "bedava enerji üreten makine" sattığında, fizik sezgisi olan kişi hesabı kafasında yapar. O enerjiyi o sürede aktarmak ne kadar ısı demek, termodinamiğin ikinci yasası ne der. Sezgisi olmayan ya parasını kaptırır ya da aşı, iklim gibi konularda mertebeyi bilmediği için kolayca manipüle edilir. Niceliksel düşünememek, modern dünyada savunmasız kalmaktır. Telefonundaki konum bile, uydulardaki atom saatlerinin hem özel hem genel görelilik düzeltmeleriyle ayarlanmasına bağlı; bu düzeltmeler olmasa GPS bir günde kilometrelerce kayardı. Einstein'ın görelilik kuramı olmasa, bugün haritada nerede olduğunu bilemezdik. Aynı fizik, hastanedeki MR'dan bir uçağın havada kalmasına, bir otobüsün neden belirli bir hızda devrilmeye yatkın olduğuna kadar her yerde. Fizik yapay zekâ çağında önem kazanıyor; ama değişen şey, bilginin türü. Makineler integrali, türevi bizden çok daha hızlı yapıyor, yani mekanik hesabın değeri düşüyor. Tam da bu yüzden "neden doğru, nereden geldi, gerçeğe oturuyor mu?" diye sorabilmenin, yani bir cevabı sınayabilmenin değeri artıyor. Üstelik çağın en büyük sorunları giderek daha çok fizik içeriyor: enerji ve iklim, mertebeler anlaşılmadan tartışılamaz. Kuantum teknolojileri, YZ çiplerinin termodinamiği, hesaplamanın enerji maliyeti, hepsi temelde fizik. Toplumun karar vermesi gereken meselelerin merkezi giderek fiziğe kayıyor. Fizikçiler için yeni iş alanları açılıyor. Ezber anlamında fizik belki değer kaybediyor, çünkü onu zaten YZ'ye yaptırabiliyoruz. Ama gerçeği muhakeme etme ve sorgulama anlamında hiç bu kadar değerli olmamıştı. Yapay zekâ fiziğin hesabını devralıyor ama bir cevabın makul olup olmadığını sezebilen kavramsal aklı devralamıyor. Acemoglu, Kong ve Ozdaglar'ın yeni NBER makalesindeki ayrım da tam buraya oturuyor. Değer kazanan, YZ'nin yerine geçtiği bilgi değil, insan aklını tamamlayan bilgi. Ama makalenin uyarısı da net: cevabı hazır veren bir YZ, bu aklı besleyen öğrenme çabasını köreltebilir. O yüzden asıl soru fiziğin değerini yitirip yitirmediği değil, o değeri korumayı bilip bilmediğimiz. nber.org/papers/w34910

Since the landmark decoding of the human genome in the early 2000s, DNA sequencing has exploded. Traditional computers have struggled to keep pace with the deluge of data and soaring processing demands, creating a bottleneck in scientists’ capacity to mine the myriad variations in DNA for biological insights—and a push for alternative solutions. Now, one option, quantum computing, may be a step closer to helping. In a new announcement, researchers say they have for the first time encoded a complete, albeit small, genome, that of the hepatitis D virus, into a quantum computer, proving in principle these weird machines could one day aid genomics research.

Anthropic had 16 AI agents build a C compiler from scratch. 100k lines, compiles the Linux kernel, $20k, 2 weeks. To put that in perspective GCC took thousands of engineers over 37 years to build. (Granted from 1987 - however) One researcher and 16 AI agents just built a compiler that passes 99% of GCC's own torture test suite, compiles FFmpeg, Redis, PostgreSQL, QEMU and runs Doom. They say they "(mostly) walked away." But that "mostly" is doing heavy lifting. No human wrote code but the researcher constantly redesigned tests, built CI pipelines when agents broke each other's work, and created workarounds when all 16 agents got stuck on the same bug. The human role didn't disappear. It shifted from writing code to engineering the environment that lets AI write code. I don’t know how you could make the point AI is hitting a wall.
