To balance this giant pencil within 5° of vertical, how much information has to flow from @mleighton.bsky.social 's eyes to his hand? His new article out today (2607.16639, with friends in Yale QBio -- @jbetancourt015.bsky.social, @emonetlab.bsky.social and Ben Machta), has an answer...
For these animals, published rates of entropy production are at most a few bits per second. That's very small compared to W, which we can estimate from their diet. And the same is true for our 𝐴. 𝑠𝑢𝑏𝑎𝑟𝑢... the bound kʙ T Σ ≤ W is quite far from being tight:

Maybe I should tweet here too. Out yesterday is my first ever experimental paper, on a novel model organism... arxiv.org/abs/2604.00453
