MA 102.    MATHEMATICS IN CONTEXT    3
A set of courses exploring interesting questions from a variety of disciplines with the aid of mathematics. (Fufills QR2 requirement.) Courses including the following are offered periodically depending on faculty availability. A student may take more than one of these courses for credit.

A. Statistical Controversies. It is often said that one can prove anything using statistics. Indeed, the reading of any newspaper or news magazine presents one with bold statements about important topics (economic, political, and health issues, etc.) based on statistical studies, together with strong opposition to those statements—in a phrase, statistical controversies. This course aims to study many such controversies to try to understand how they arise, what statistics lie behind them, and how at least some of them might be avoided by proceeding with greater care. Intended for students with little or no experience with statistics. (Fufills QR2 requirement.)

B. Modeling Epidemics. This course several mathematical techniques for modeling epidemics, including differential equations and statistical methods. (Fufills QR2 requirement.)

D. Mathematics in Context: Mathematical Models for Business and Economics—Efficient Planning. What is the best way to allocate scarce resources? In the business world, linear programming is often used to answer this question. Phone companies, oil refineries, airlines, and many other businesses use linear programming to schedule transportation networks, plan portfolios, control inventories, and maximize profits. Since its invention in the 1940s, linear programming has become increasingly important, and according to some estimates, well over $100 million in human and computer time is spent yearly in the formulation and solution of linear programming problems. In this course, the student will be introduced to linear programming problems and their solution, related topics such as sensitivity analysis and integer programming, and various other mathematical models useful in business and economics, such as Leontief economic models, basic probability theory, and Markov chains. (Fufills QR2 requirement.)
