An interview with James A. Yorke

Jim Yorke, also known as Dr. Chaos, is famous for coining the mathematical term "chaos" (with T.Y. Li in a 1975 paper entitled Period Three Implies Chaos). Tim Sauer (George Mason University) talked to him at the Joint Mathematics Meeting, January 7-10, 2004 in Phoenix, Arizona. A story about chaos, interdisciplinary research and the legs of an elephant.

An interview with Jack K. Hale

Professor Jack K. Hale is a world renowned leader and among the most influential persons in the field of nonlinear dynamics in our age. He was an originator and pioneer in many important areas in the interface of dynamical systems and differential equations including nonlinear oscillations, stability and bifurcation theory, functional differential equations, and infinite-dimensional dynamical systems defined by parabolic and hyperbolic equations. Professor Hale's influence in the field has gone far beyond his papers and books. By being a leading mathematician and a person of exemplary character, he has had tremendous impacts on the career developments of many people around him and has brought the best out of many of us working in the field.
