COVID-19 Science

In a matter of mere days in early 2020, our lives were turned upside down. We read about and listened to the available information on COVID-19 and wondered how to protect ourselves against an unseen enemy. Many turned to science looking for answers, but this virus was new to everyone and the science was evolving. The resources on this page explain the science of COVID-19, how it spreads, how to protect yourself, and how scientists around the world have worked together to understand it.

How To Tell If We're Beating COVID-19

This video is a collaboration with Aatish Bhatia about how to see the COVID-19 tipping point using a logarithmic scale in "phase space," plotting the growth rate against the cumulative cases, rather than either of these against time.
