The 2013 Department of Mathematics and Computer Science Awards Ceremony will be held 4-5:45 p.m. Thursday, April 25, in Carlo Auditorium of Tegeler Hall. Tim Chartier, from Davidson College, will present "Putting a Spring in Yoda's Step."

When the character Yoda first appeared on the silver screen, his movements were due to the efforts of famed muppeteer Frank Oz. In Star Wars Episode II: Attack of the Clones, Yoda returned to the movies, but this time the character was not a puppet but a digital image within a computer.

This talk will discuss the role, or more aptly the force, of mathematics behind a few aspects of movie special effects. Armed with differential equations, animators can create a believable flow to Yoda's robe or a convincing digital stunt person.
