Crossing the boundaries of physics and biology, Santa Fe Institute fellow Geoffrey West has moved beyond establishing the relationship between blood flow in the body and traffic flow in cities. Speaking yesterday to an audience of students, faculty and community members at the University of Missouri’s Monsanto Auditorium, West said studying how the natural environment reacts to problems can give clues for how cities should solve problems such as crime, pollution and global warming. "We better understand cities if we’re going to solve these problems," West said. "We cannot in my opinion we will not - solve the problem by focusing on global warming, by focusing on energy and the environment and then focusing on the market. … We need to create a generation of people very quickly that think in broader terms, seeing these as integrated problems."
