this is humanities phd level math


Some of Renato Renner's own PhD students refused to work on his result because it disturbed their sense of self. What he proved (with Frauchiger): quantum mechanics, applied consistently to the physicists who use it, generates flat contradictions… for the quantum observers themselves. Renner himself went from many-worlds to QBism to what he calls "no man's land." curtjaimungal.com













I regret to inform you that I am still a physicist, and will be, for the rest of my life.







It's hard to find physicists - other than those still working in/around String Theory - who are still excited about String Theory. It simply is not talked about much outside the narrow specialization. It's kind of mind boggling that this kind of hype continues.

Human insight is still a thing: over the last few years many computing resources were thrown towards the Merzon-Smirnov conjecture on maximal Schubert polynomials, including DeepMind's FunSearch. In the end it fell to a human-generated targeted check: arxiv.org/abs/2603.20104


After the apparently amazing announcement by @mathematics_inc on the formalization of a major recent Fields-medal winning theorem, i had no idea how pissed the math-formalization community is. Very worrying discussions by some of the leaders/founders of Lean's mathlib. cc @ChrSzegedy



The Hotlzman Shield in Dune is one of the perfect examples of adding a tiny thing to a setting to get a vibe you want out of it. In Dune's case: - Holtzman Shields stop fast moving objects. - Lasguns (particle beam guns in Dune) can cause a nuclear explosion if they hit a shield, so they're not commonly used. - Melee is the dominant form of combat, trying to strike slow to penetrate the shields. - Projectile weapons exist but they're designed around boring through or disrupting shields, but a skilled combatant can deflect the slow moving projectiles. - Heavy artillery can still kill shielded humans through sheer transfer of force or heat, which the shield can't block. - Anti-vehicle weapons are built around these principles because the vehicle might be shielded. Dune codified the idea of high tech sci-fi where you still have melee and the idea of "oh here's this piece of technobabble that let's me have what I want in my sci-fi setting." Gundam's Minovsky Particle and Mass Effect's Element Zero owe the Holtzman Shield their existence.

@InnaVishik Prof. Aobo Li gave a great presentation at APS (MAR-G01:4) on the ML for physics panel. He mentioned that deploying neural nets on FPGA chips is a "major research direction." Research-grade FPGAs—like the Cyclone 10 GX in my @analogue N64 emulator—are a few hundred bucks.
