&quot;Imagine you are holding a doughnut in the dark,&quot; Emory University mathematician Ken Ono says. &quot;You wouldn&#039;t even be able to decide whether it has any sprinkles. But the information in our O&#039;Nan moonshine allows us to &#039;see&#039; our mathematical doughnuts clearly by giving us a wealth of information about the points on elliptic curves.&quot; Credit Photo by Stephen Nowland, Emory University
