The vOICe for Android version 2.65 is now at 99.21% crash-free users, and it looks like this percentage is still going up; crashes are annoying but harmless: you just restart the app; will brain implants for vision have 99.21% seizure-free users?

Brandolini's Law is terribly frustrating. 😖

Ice Eggs beach. Thousands of balls of ice cover a beach in Finland due to a phenomenon that occurs when ice is rolled over by water and wind. 💙

Physics didn’t take away your free will, and quantum mechanics didn’t give it back. I won't try to convince you of one point of view or another about free will in general. I’m a physicist, and what I'll explain why, no matter which viewpoint you choose, the cold, impersonal laws of physics didn’t take away your free will – nor did quantum mechanics give it back by changing our ideas about randomness.

There’s a difference between underlying (latent) truth and syntax, even if the syntax is very high quality.

“got my first question at the library this week from someone who was looking for a book that the bot had recommended. They couldn't find it in our catalog. Turns out that ALL the books that #ChatGPT had recommended for their topic were non-existent. Just real authors and fake titles cobbled together.” @bibliotecaria

How students reliably score A grades with #chatgpt. But also how to but it to #creative use! Getting those #prompts right is hard.

If you're interested in #chatGPT's implications for higher education, I wrote a brief thing about it.

How #sleep shapes what we remember—and what we forget. Researchers are starting to decode the #neural changes during sleep that underlie #LongtermMemory. A PNAS news feature: https://www.pnas.org/doi/10.1073/pnas.2220275120 #neuron #synapse #hippocampus #brain

Lack of visual experience affects multimodal language production: evidence from congenitally blind and sighted people https://onlinelibrary.wiley.com/doi/10.1111/cogs.13228 "blind people's speech focused more on path and less on manner of motion, and encoded paths in a more segmented fashion using more landmarks and path verbs"; #blind #neuroscience #linguistics

The brain's ability to perceive space expands like the universe https://www.salk.edu/news-release/the-brains-ability-to-perceive-space-expands-like-the-universe/ "neural networks responsible for spatial perception change in a nonlinear manner"; #neuroscience

Scientists discovered why Roman buildings have survived so long. It's because they included an ingredient in their concrete – once thought to be from shoddy mixing – that helps the concrete self-heal as it cracks over time. The discovery may help future concrete mixes become self-healing and last longer.
