"The Beautiful Problem of Turbulence" presented by Sam Stewart, Ph.D. Candidate in Mathematics at the University of Minnesota, at the Bryant Lake Bowl on January 17th, 2017.
"What do golf balls, whales, and airplanes have in common? They all struggle with one of the oldest and most difficult problems in physics and mathematics: turbulence. Turbulence is a bizarre and beautiful phenomenon that occurs when substances like water and air flow really fast. Most people are familiar with turbulence during air travel, but the problem is much bigger and impacts fields as diverse as national defense, NASCAR, and oil. It's so complicated that even our most powerful super-computers choke on the calculations. During the last century, mathematicians have arrived on the scene and struggled to verify if our core model is correct. What makes turbulence so hard and why should we care about understanding it? Join Sam Stewart, a Ph.D. student in mathematics studying fluid dynamics at the University of Minnesota, as he shares the story of one of our most fundamental and fascinating natural phenomena."
