Clara's Corner: Pushed Off of Equilibrium But Still Holding It Together—Relaxing With Unstable Materials with Kit Umbach

Wednesday, February 6, 2013 at 7:30pm to 8:30pm

Clara Dickson Hall, FIR Apartment

Pushed Off of Equilibrium But Still Holding It Together—Relaxing With Unstable Materials. Some solids can “flow” like a fluid. Other solids behave like frozen liquids. Such solids are not in equilibrium, and their instability produces beautiful and valuable phenomena. In this Clara’s Corner, Kit Umbach of the Materials Science and Engineering department will share some examples of how materials as common as glass or silver-gold alloys can surprise us when we push them off equilibrium. At the end of the evening you’ll get a chance to push on a blend of cornstarch and water—is it liquid, solid, or both? "
