Had some fun with shared array buffers over many months of free time. Skip to the end to play around with the final app. Open to ideas on how to simulate more whilst staying in js land.

I started teaching my daughter physics by showing her how things actually work - plucking guitar strings to explain vibration, mixing paints to understand light, dropping objects to see gravity in action. She learned so much faster through hands-on exploration than through books or videos. That's when I realized: what if I could recreate these physical experiments as interactive simulations? Lumen is the result - an interactive physics playground covering sound, light, motion, life, and mechanics. Each module lets you manipulate variables in real-time and see/hear the results…

The little particles will gravitate to your cursor (or touch location), and can even enter stable orbits if the conditions are right! Mainly an excuse for me to experiment with wasm and WebGL, but it makes for a surprisingly good fidget toy.

Hey HN! We are the co-founders of Elodin (https://elodin.systems/), a code-first physics simulation framework. We just open-sourced our core libraries on Github: https://github.com/elodin-sys/elodin Have you ever wondered what happens when a satellite is first placed into orbit? It turns out that often, they tumble out of control, end over end, in a miraculous fight against stability. Check out our demo here of a control system attempting to rectify this: https://app.elodin.systems/sandbox/hn/cube-sat The spacecraft does not…

Hi everyone! I’m the founder of Explanations (https://explanations.app). I’m building a website where students can get college level math & physics help for 1/10th the cost of private tutoring. You’d type a question, and your teacher replies by drawing a Youtube/KhanAcademy-style video; and this happens asynchronously throughout the week. When I was studying at MIT, I often had to wait 40-60 minutes in line just to get 5 minutes of “help” from a TA - when I needed 1-2 hours. I understood that TAs can’t spend all their time helping me. That’s understandable. But what made…

A pretty simple but fun to play with simulator for a concept from mathematical physics called the "2D Coulomb gas". I originally made this for my Bachelor's thesis to create pretty pictures and build intuition but have recently gotten it a fresh coat of paint and better performance curtesy of WebGPU acceleration (ported with liberal help from Codex to get through all of the boilerplate). Play around with it - hopefully read up more on the 2D Coulomb gas because it is an incredibly deep topic research wise.
