Opus has the simulation running on GPU now so we're up to about 50,000 ticks per second. I'm working on a new memory design where I store many values in a ring for better large-scale storage.

I spent the evening with one of the most famous books regarding digital art. What stayed with me wasn’t just the images, but the words they used for them: “graphics,” “programming,” “systems,” “cybernetics.”Long before anyone talked about a market for digital art, artists and engineers were already inventing a language for a new way of seeing.

@jwt0625 Is it the "what makes you so special that we should listen to you?"-vibe, or the "do you accept our cookies?"-filter? Who knows 🤷

Snell’s Law, also known as the Snell-Descartes law, dictates how light bends when crossing the boundary between two transparent mediums with different refractive indices.

I still can’t believe it. My PhD project of 8+ years at @HillmanLab, @ZuckermanBrain and @ColumbiaBME was published today in @NatureComms! We present a newly discovered body map in the secondary motor cortex (M2) of the mouse brain.

I am building a 3D book on how planes fly, for physics students. It will have ten lessons that each pair an interactive simulation with a quiz. A glimpse of three lessons.
Will publish the full book on my website if there is enough interest.

The waves this evening at Shore Acres, Oregon were absolutely incredible!!

One of the things that can happen to your body schema on high dose (breakthrough level) DMT.

It's usually disorienting, but it also enables experiencing an entirely new distance function between parts of your body, sometimes even with topological changes (e.g. like your forehead becoming connected to your big toe!).

Don't panic, breath, and be equanimous. It will revert back to normal within ~10 minutes. :-)

I wish everytime I open X, I see only posts about Math, Physics and other STEM fields.

Hydrogen through the eyes of Gemini 4 Hydrogen itself: quantum orbitals from 1s to 4f, merging into H₂, procedural ambient and sudden poetry in the subtitles «a single proton dreaming in liquid light».

Very cool how you can see the polar vortex become massively destabilized in this video
