Graphics: Exponential growth and how to “flatten the curve”

This tutorial from The Washington Post uses animations and graphs to explain the math behind the current drive for social distancing to slow down community transmission. The simulation looks at four options, from no restrictions at all to a forced quarantine (think Hubei province in China) and with two different buy-ins of social distancing (75% and 87.5%).

The simulations are generated randomly each time you visit this page, which makes this a good exercise for students. They can see how the sames rules will produce different outcomes, not because of a flaw in the rules, but just because of the randomness of life.
