Featured Events
Constitutional Conversations

Unraveling the Science Behind Sweaters
Part of the Penn Science Café series, participants in this session will learn more about the science behind sweaters—and knitting in general. Randall Kamien, Vicki and William Abrams Professor in the Natural Sciences, will discuss how this deceptively complex, centuries-old practice is shaped by geometry and the mechanical properties and behavior of materials. Free and open to the Penn community. Register to attend.
Randall Kamien of the School of Arts & Sciences and long-time collaborator Geneviève Dion, a professor of design at Drexel University, are investigating the mechanics of knitting, an area of research that represents a significant shift in understanding and using fabrics.
