Ricard Solé @ricard_sole How complex can cognition be in brain organoids? Since they do not sense or act on their environments, they lack cognitive complexity or agency. Without the organism, the “spherical brain” (my drawing) is a fascinating window to evolution and disease but not to actual cognition. https://pic.x.com/6r4kshpocm Replying to @ricard_sole Jeff’s brain was

@DvirGur I had to go to Google Scholar and such sites to find your publications. The links on your site always fail. It recommends clearing the cookies, but that is not a good idea. “Too many redirects” generally means you guys need to look carefully at cookie fiddling and “keep it simple”. This link (below)

Dvir Gur @DvirGur Have you ever wondered how animals like fish, and chameleons rapidly change their color to camouflage or communicate? Our recent work shows that Zebrafish quickly alter their structural colors by changing the spacing between their intracellular crystals using motor proteins Replying to @DvirGur Is there any chance the electric fish works the

Fly with Magnar: Why are so many pilots wrong about Bernoulli’s Principle? at https://www.youtube.com/watch?v=uyRx25MSWng @woodpile66 Most folks here seem to say that low pressure exists because the flow speeds up, but that group does not account for why the flow sped up in the first place, or the mandatory physics. I offer that the wing

Roger Grosse @RogerGrosse Amortized variational inference is neither amortized nor variational nor inference. x.com/jpillowtime/st… Jonathan Pillow @jpillowtime Amortize means to “to pay off a debt with regular payments” But in amortized inference you pay a big up-front cost to train an inference network, then inference is cheap per datapoint. Isn’t that the opposite of amortization?

All human languages, all domains, all places, all devices – global open resources for all humans Computer memory and processors changed the face of human navigation in cities, so too can it change the face of navigation through fragmented and Byzantine sets of rules for every discipline and topic. It is not only memory devices

Dear SETI, Looking at the whole Internet, and the potential of true AIs to allow systems to essentially live forever, I realized that exploration and development of galaxies is likely the norm, not the exception in the universe. An evolved natural lifeform might well develop systems that record all knowledge and process it. The system

Fusion for SpaceX levitation, industrial and space needs. Global open tokens and global open resources I was reading https://en.wikipedia.org/wiki/Levitated_Dipole_Experiment today and encouraged. While the economics of bulk electricity production are not particularly favorable, there are many new transportation, industrial and space applications where GigaWatt and larger power modules are needed. For instance to
