Information Geometry a la carte! IG is about ***dual geometry***: Build your own information geometry by choosing (1) manifold M, (2) metric g (3) affine connection ∇, torsion-free Dual connection is simply ∇*=2∇^g- ∇ using Levi-Civita connection ∇^g see pinned tweet

20W brain vs. AI grid! Cool talk by Professor Earl K Miller! AI data centers are straining our energy grid, consuming massive amounts of power and water. 🔌 Meanwhile, the human brain executes vastly more complex, self-controlled cognition on just 20 watts—the power of a dim light bulb. 💡 The secret? Shifting away from digital connectionism and embracing the efficiency of analog, wave-based parallel computation. It’s time for computer architecture to learn from basic biology. 🧠t.co/ToYb0Z8nzE 🌀 @MillerLabMIT #CognitiveScience #AnalogComputing #Neuroscience #DeepTech #EnergyEfficiency #ArtificialIntelligence #BrainWaves

This time, celebrating 19 days of being “on hold” on arXiv! “A Braitenberg vehicle’s habitat”, w/ @_fernando_rosas and Filippo Torresan. Accepted at ALIFE 2026. What part of the environment constitutes an agent’s effective world, its habitat? 1/

In the search for simple models of high-dimensional neural activity, one might hope for a mean-field theory Led by Luca Di Carlo, @framigna, and @wbialek, we show that simple versions of this idea fail and propose extensions that point in the right direction

@TouhouEnjoyer_ something something about burning a village for warmth or something

I was recently told that approaching a woman with the explicit purpose of a romantic relationship was evil and objectifying. I'm now learning being friends with a woman and falling in love with her ovrr time is also evil. The conclusion: I am evil for wanting to love.

Convert Flat Games to VR + add stuff like FBT etc. That’s what’s going to sell VR. Not Low Poly standalone Cashgrab apps. #vr #youknowimright

We are entering a completely new era of science Here is Yuji Tachikawa from Japan (Mathematical Physics, String Theory, QFT) on recent progress in his own work using Fable 5 : "I've been trying out Claude Fable recently, and last night, on a whim, I showed it my research notes about a collaborative project that's seen no progress in the past six months or so and asked for its thoughts. To my surprise, it made a non-trivial observation and essentially solved it." "I was also surprised that it was using sympy to automatically write code and verify his own predictions." "Fable probably seems like it properly understands string theory and has intuition too—that's my impression"

There's a subreddit where women post a picture of their dinner and air out their frustrations going on in their lives. >Woman, 26 Asian >Married a guy she hates >Moved across the continent to be with him >Hates his personality(fishes, beer, etc) >Boring Midwesterner >Peaked in high school >Has to "be his mom" >Plans on getting another job and leaving him This guy probably has no idea she hates him and is going to get financially ruined

Function is not tied to specific brain structures or time scales. The brain is not just a set of parts that each “do their own job”. Instead, networks are multifunctional and active across different speeds simultaneously. doi.org/10.1073/pnas.2… #neuroscience

The myth of the single-process brain: officially busted. 🧠New research shatters old assumptions by proving the human connectome runs multiple entirely separate, asynchronous information streams in parallel. It’s a multi-track orchestra using the exact same spatial blueprint. The ultimate game-changer? This proves high-speed EEG captures unique, high-fidelity connectome data completely independent of fMRI. This completely validates low-cost, standalone EEG as a powerful diagnostic tool—democratizing neurological care for patients who can’t access or undergo expensive MRI scans. #Neuroscience #BrainMapping #NeuroTech #MedTec h#HealthEquity #EEG #Connectome #MRI #EEG *Original Research: Open access. “Shared spatial and temporal principles govern connectome dynamics across timescales” by Anne-Lise Giraud, Jeremy Harper, Jonathan Wirsich, Maximillian Kirichenko Egan, Parham Mostame, Samar Wagih ElSayed, Sanmi Koyejo, Sepideh Sadaghiani, Sophia A.

@dogeofficialceo Sørloth looks even more retarded in this angle

This angle is even worse. What was Sørloth even thinking? If he’d passed to Haaland, Norway might still be in the World Cup.
