MATH 100: The Mathematics of Democracy
We aspire to live in a democratic society, but what exactly does this mean? How can we decide, for example, which candidate in an election has the support of the people? How can Congressional seats be apportioned to the States "according to their respective numbers?" Are these things even possible? Recently, mathematical analysis has brought new insight to these old questions, often with surprising results. We will study some of this work and its implications for our democratic aspirations, and perhaps gain some appreciation for the power and elegance of mathematics along the way.

Prerequisites: Mathematics 211. 6 credit; Mathematics and Natural Sciences, Formal or Statistical Reasoning; offered Spring 2014 · S. PattersonExtended departmental description for MATH 351
What happens to calculus when you replace the real variable x by the complex variable z = x + iy and the realvalued function y = f(x) by the complexvalued function w = f(z)? For starters, the statement "f is differentiable" becomes more powerful while the idea of integration becomes more flexibleyou can now integrate along various paths in the complex plane. This subject is inherently elegant – arguably among the most beautiful subjects in mathematics. But, perhaps surprisingly, this subject is also one of the most practical and can be applied to "real" mathematical and physical problems in which no complex number occurs. This course has connections with many other upperlevel math courses. Those who have taken other courses should enjoy discovering some of those connections. However, Math 211 is really the only prerequisite.
