Dr. Stephen Schneider believes that in addition to the usual array of baffling scientific uncertainties, cultural, psychological and educational obstacles make these already difficult problems virtually unsolvable so long as we continue to deny their existence. In this lecture, Dr. Schneider, a professor from Stanford University and a public spokesman for global change issues, provides an overview of the science behind global change and discusses public resistance to its evidence. Dr. Schneider argues that in order to have a functioning democracy, citizens must start understanding and grappling with these pressing issues in global change.

"Chaos" and "fractals" are two terms signaling a scientific revolution that has taken place in the last 20 years. In this talk, NASA researcher Warren Wiscombe explains how ordinary objects and events such as snowflakes and snowboarding exhibit the characteristics of chaos. Additionally, Wiscombe describes how chaos and fractal theory can shed new light on long-standing scientific conundrums such as weather and climate, fluid flows, cells, and life itself.
