Keith & Russ talk with Rudolf Seising of the Friedrich Schiller-Universitaet Jena in Germany. Seising talks about his interest in the history of science, specifically in the 20th century, and on how scientists communicate and compete with each other. He also discusses "fuzzy logic" - a mathematical theory that relies on words rather than numbers. It has been used to control steam engines, and to make cameras and Japanese rice cookers.
