This course examines how the idea of "the modern" develops at the end of the 18th century in European philosophy and literature, and how being modern (or progressive, or hip) became one of the crucial criteria for understanding and evaluating cultural change. Are we still in modernity, or have we moved beyond the modern to the postmodern?

Behavioral economics couples scientific research on the psychology of decision making with economic theory to better understand what motivates financial decisions. In A Beginner’s Guide to Irrational Behavior, you will learn about some of the many ways in which we behave in less than rational ways, and how we might overcome our shortcomings. You’ll also learn about cases where our irrationalities work in our favor, and how we can harness these human tendencies to make better decisions.

Networked Life will explore recent scientific efforts to explain social, economic and technological structures -- and the way these structures interact -- on many different scales, from the behavior of individuals or small groups to that of complex networks such as the Internet and the global economy.
