Classical billiards can compute.
With Isaac Ramos, we show that 2D billiard systems are Turing complete, implying the existence of undecidable trajectories in physically natural models from hard-sphere gases to celestial mechanics.
Determinism ≠ predictability. 🎱🧠 @upc.edu @ricardsole.bsky.social

8675309 is prime, and so is 8675311, so if you ever need a middlin'-large pair of adjacent primes to test your cryptographic suite, all you need is a 1980s earworm and a +2 and you're all set.
Man, everything is so bleak, anyone got a fun fact or little bit of trivia they want to share

There are still spots available in this workshop! Vertigo peeps take note! No writing experience needed, but also since it's writing prompts it should be fine for people with loads of writing experience.
Do you suffer from vertigo? Or do you care for someone who does? Would you like to explore your experiences through creative writing? If so, please sign up for this online workshop with the wonderful @marissalingen.bsky.social 5pm GMT, 23rd November. Email [email protected] to register.
