About Simons Foundation Presents
A free event series, Simons Foundation Presents aims to engage a diverse public audience in a wide range of accessible, meaningful and fun science and mathematics programming.

One would think that the humble sphere, which has been studied for as long as humankind has looked upon the heavens, has already revealed all its secrets. And yet, it is the subject of active research from areas as far apart as number theory and dynamical systems. In this lecture, Alex Kontorovich will describe some of these connections, both ancient and modern. He will also showcase how mathematics is not a random collection of disjointed facts (as often learned in school), but rather numerous sweeping landscapes, all deeply interconnected and influencing each others’ development.
