This is a quantum mechanics simulator!!! I've been working on this for so long so please heart and star!!!! USE TURBOWARP. PLEASE. https://turbowarp.org/1308938943?turbo&fps=60 Instructions: click start. the brightness factor just makes it so you can see it better. The red is a potential bump (like a hill) and the blue is a potential well (like a hole). To make your own bumps, walls, and wells, go to the initialize block, go to the bottom of it, and change how you set the potential. To make the particle start going in a different direction, be a different size, or go a different speed, look at the beginning of the initialize script.
All me. :) As far as I can tell, this is the only thing like it in scratch. This project evolves the wave function of a particle using the 2d Schrödinger equation. It took me forever. please heart+star!
