If the book of nature is written in the language of mathematics, as Galileo once declared, the Covid-19 pandemic has brought that truth home for the world's mathematicians, who have been galvanized by the rapid spread of the coronavirus.

So far this year, they have been involved in everything from revealing how contagious the novel coronavirus is, how far we should stand from each other, how long an infected person might shed the virus, how a single strain spread from Europe to New York and then burst across America, and how to ‘'flatten the curve’' to save hundreds of thousands of lives. Modeling also helped persuade the Centers for Disease Control and Prevention that the virus can be airborne and transmitted by aerosols that stay aloft for hours.
