2D Coulomb Gas Simulator
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 I originally made this for my Bachelor's thesis to create pretty pictures and build intuition but have recently gotten it a fresh coat of paint and better performance curtesy of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.

In plain words
The 2D Coulomb Gas Simulator is an interactive tool for exploring a mathematical physics concept called the 2D Coulomb gas. Originally created for a Bachelor's thesis to visualize and understand the topic, the simulator has been updated with WebGPU acceleration for improved performance. Users can adjust parameters and observe particle interactions in real-time, making it useful for building intuition about this research area in mathematical physics.

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
