Follow a changing state through time

A cup of tea cools, a diffusion model turns noise into a picture. Step either one forward with Euler's method, learn why too big a step explodes, and add noise the right size.

LESSON OVERVIEW12 min lesson

Lesson overview

A cup of tea cools, a diffusion model turns noise into a picture. Step either one forward with Euler's method, learn why too big a step explodes, and add noise the right size.

What you’ll explore

  • Read a differential equation as a rule for change, take Euler steps and spot when a step is too large, and add Brownian noise that scales with the square root of the step.
