"...religion-adjacent projects like artificial intelligence..." Ten years ago I would have been pretty surprised to encounter a phrase like that. Techbros have since been swallowed by Roko's Basilisk? :P

This video on how we calculate cosmic distances is such a joy. Check out the first part too. youtu.be/hFMaT9oRbs4?...

Enjoyed sharing our work on electric fish with @dryohanjohn.bsky.social⚡🐟 Their electric "conversations" help us build models to discover neural mechanisms of social cognition. Work led by Sonja Johnson-Yu & @satpreetsingh.bsky.social with Nate Sawtell kempnerinstitute.harvard.edu/news/what-el...

Now on display at the #KempnerInstitute: paintings by Arturo Deza, a professional neuroscientist and artist who combines his expertise in the science of vision with an improvisatory painting style. @dryohanjohn.bsky.social sits down with Deza to discuss his work. Read more: bit.ly/3WTUmCH #ML #art

What can weakly electric fish teach scientists about #NeuroAI? Read about how #KempnerInstitute’s @kanakarajanphd.bsky.social is studying elephantnose fish to gain insights into #collectiveintelligence and #AI systems. bit.ly/4gQMbi1 @harvardmed.bsky.social @dryohanjohn.bsky.social

This piece about the "shift to vibes" might be put into a kind of dialogue with @peligrietzer.bsky.social 's Theory of Vibe [link below]. thepointmag.substack.com/p/vibe-drift

"An audible sound at 3,000 Hz, the frequency at which our ears are most sensitive, can move the eardrum as little as 1/10th of the diameter of a hydrogen molecule." From 'Perfecting Sound Forever: The Story of Recorded Music', by Greg Milner

"A mechanistic circuit model provides an explanation for the observed properties, and suggests the transition between stages represents a transition from more sensory-driven to more circuit-driven dynamics." The urgency signal that Paul Cisek often talks about might dovetail nicely with this.

The irony of reinforcement learning in ML is that an ostensibly real-time, online form of learning requires random sampling from an offline buffer of perfect memories. Is there reason to assume this happens in biological systems? Perhaps this is what the hippocampus-accumbens projection helps with?

Just finished season 2 of 'Paatal Lok'. Brilliant show. Indian crime noir done perfectly. Dark, funny, and exceptionally well made.

"We are interested in philosophy and think it is important for statistical practice—if nothing else, we believe that strictures derived from philosophy can inhibit research progress." 😂 Gelman & Shalizi (2011). Philosophy and the practice of Bayesian statistics https://doi.org/10.48550/arXiv.10…

Microsaccades are one of my favorite topics in visual neuroscience. And primates seem to deploy them far more often than other species. jov.arvojournals.org/article.aspx...

"The poetic image is a sudden salience on the surface of the psyche..." - Gaston Bachelard, 'The Poetics of Space'

I just read Ursula K. Le Guin's essay 'The Carrier Bag Theory of Fiction'. A pithy little critique of the excessive focus on hero narratives. Recommended!

"We conclude that conventional networks trained with supervision lack a mechanism to learn symmetries that have not been explicitly embedded in their architecture a priori."

When books choose violence: “The attentive reader will have noticed that equation 4 in the previous section is…” Me, busted: sure

"Even a potato in a dark cellar has a certain low cunning about him which serves him in excellent stead." - Samuel Butler (in 1872!) From one of my favorite passages of all time. I was explaining the origin of the phrase "Butlerian j!had" to a friend just now. www.marxists.org/reference/ar...

Was chatting with some friends about parallel transport, which led to some discussion of differential geometry... and that led us to this fascinating Wikipedia page. [Also: the article title could be the name of a really cool postrock album.] en.wikipedia.org/wiki/French_...
