How the docs work
Every physics page follows the same shape.
Layer 1: Intuition
Section titled “Layer 1: Intuition”Plain words, pictures, and a live simulation. No equations. If you only read this layer you will still understand what the phenomenon is and why it happens.
Layer 2: The mathematics
Section titled “Layer 2: The mathematics”The governing equation, where it comes from, and its exact solutions. This is what you would find in a good textbook, written to be read rather than skimmed.
Layer 3: The numerics
Section titled “Layer 3: The numerics”How the engine actually solves it, which method, why that one, and the validation results that prove it works. This layer links straight into the source code.
Live simulations are the real engine running in your browser through WebAssembly. They are not videos. Drag the sliders, and the numbers you see are being computed as you watch.
