Show HN: 2D Coulomb Gas Simulator
by swesnow
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 I originally made this for my Bachelor's thesis to create pretty pictures and build intuition but have recently gotten it a fresh coat of paint and better performance curtesy of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.
Warning: if you increase the steps per frame it will break your phone. At least with my iPhone and Safari it stalls the entire phone.
Yes, the web page persists through reboots.
You have to painfully force quit Safari by going through the motions of the gestures, wait for the phone to respond, and then quit Safari from the card task switcher.
Awesome! Beautiful work. Mesmerizing, even
