What it is

3Blue1Brown builds toy SIR models to simulate how an epidemic spreads and tests scenarios like social distancing, travel restrictions, central gathering places and quarantine. It was made during the early COVID-19 outbreak.

Why Hacker News recommends it

HN pointed to it during 2020 as a digestible, well-made illustration of epidemic dynamics and interventions.
