This is a great game, hadn't heard of it before.
Simple rules but insanely hard levels.
Astra worked for a hours and solved 6 levels which is a good result.

hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final
((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

Following up on the suggestion from Will Sawin, here is an illustration of the new configurations that disprove Erdos' unit distance conjecture (made with the help of ChatGPT 5.5 Thinking).
Rule 110 in lamp shade form. There are lots of other interesting cellular automata, objects, and styles I am playing with as well.
I watched The Thinking Game last night which was really good. The prominently featured pencil sculpture was designed by my dad!

Project Genie is a great way to experiment and get a feel for world models and this exciting research frontier.
I've been having fun exploring interactions that are usually quite hard to simulate with physics engines 😀

Triple inverted pendulum in transition control
A classic control problem, done in real time.
This setup moves smoothly between all eight equilibrium points of a triple inverted pendulum.
The system reacts every 1 millisecond, which shows how fast modern control loops can be.
• Real-time control at 1 ms sampling
• Stable transitions between multiple balance points
• Built with Simulink and LW-RCP02 hardware
This is a beautiful example of how theory meets practice in advanced control engineering.

Here's some footage from my Tesla's dashcam.
Just kidding. Did you believe me?
The truth is, this video is completely fake. It was generated by Tesla's world simulator, a generative AI model that not only allows Tesla to generate realistic synthetic training data, but also validate new versions of their self-driving model.

Yes, pixels are in the direction of photons.
Is anyone who follows me a programmer actively working on NN/AI, thinks the AI risk is real and high enough that it takes up decent mindshare, and in the greater NY area? Looking to chat via DM.

I added this interesting radial magnetic bound state setup realized in 2021 to my ResearchGate page as researchgate.net/publication… where full description of the setup can be found.
"Every equation and every explanation used in physics must be compatible with the symmetry of time. Thus we can no longer regard effect as subsequent to cause. If we think of the present as pushed into existence by the past, we must in precisely the same sense think of it as pulled into existence by the future." - Gilbert N. Lewis (the guy who discovered covalent bonds, coined 'photon', and first isolated heavy water)

This is what it looks like in Genie 3.
It is 2025. You type the world you want. The rain comes. The lights burn. A train glides away, straight and cold. People stand close. They wait and do not speak. Above them fish turn slow and bright.
You type more. The city answers. It gives you color and noise and steam. It gives you the long street and the wet neon. It gives you the old hunger too. You feel it in the crowd. You feel it in the rail as it hums past.
You try again. You ask for quiet. The rain softens. The crowd breathes. The koi slow and dim. It is almost right.
It's Genie 3.

New paper: World models + Program synthesis by @topwasu
1. World modeling on-the-fly by synthesizing programs w/ 4000+ lines of code
2. Learns new environments from minutes of experience
3. Positive score on Montezuma's Revenge
4. Compositional generalization to new environments

We must not piss away our credibility. Credibility is all we have.
