The Mathematics Program has three main functions: to provide students in the program with the opportunity to study the primary areas of contemporary mathematics, to provide physical and social science majors with the necessary mathematical tools for work in their disciplines, and to introduce all students to serious and interesting mathematical ideas and their applications.
The program requirements are flexible enough to allow a student to prepare for graduate study in mathematics, professional schools (such as medical or law), or employment in the public or private sector. Students in the program are expected to follow the standard divisional procedure for Moderation and to fulfill the college-wide distribution and First-Year Seminar requirements.
By the time of Moderation a student in the program should have taken (or be taking) these courses or their equivalents: Mathematics 141, Calculus I; Mathematics 142, Calculus II; Mathematics 213, Linear Algebra with Ordinary Differential Equations; and Mathematics 261, Proofs and Fundamentals. By graduation, a student must have completed: Mathematics 241, Vector Calculus; Mathematics 332, Abstract Algebra; Mathematics 361, Real Analysis; at least two other math courses numbered 300 or above; a computer science course, preferably before beginning the Senior Project; and the Senior Project.

CoursesThe following descriptions represent a sampling of courses from the past four years.
An introduction to core ideas in statistics that are needed to make sense of what is found in media outlets, online surveys, and scientific journals. Most concepts are introduced in a case-study fashion; statistical software is used to analyze data and facilitate classroom discussions. Primary goals are to foster statistical reasoning and assist in making informed conclusions about topics involving data. Prerequisite: passing score on Part I of the Mathematics Diagnostic.
Data and Decisions
This course examines applications of mathematics to a number of topics related to data and decision making. Topics are chosen from three relevant areas of mathematics: voting systems, networks, and statistics, all of which involve extracting information from various types of data. No particular mathematical preparation is needed beyond basic algebra and a willingness to explore new ideas, construct convincing arguments, and use a spreadsheet. Prerequisite: passing score on Part I of the Mathematics Diagnostic.
Time, Space, and Infinity: Mathematical Perspectives on Philosophical Paradoxes
If time is composed of moments with zero duration, is change an illusion? Beginning with Zeno’s ancient paradoxes, fundamental problems on the nature of time and space—and related ones regarding infinity—have bedeviled thinkers throughout the contemporary period. This course provides a beginner-friendly tour of some of mathematics’ most profound discoveries (irrational numbers, limits, uncountability) and the concerns that arise in answering such intractable questions. Prerequisite: Passing score on Part I of the Mathematics Diagnostic.
Mathematics and Politics
This course considers applications of mathematics to political science. Five major topics are covered: a model of escalatory behavior, game-theoretic models of international conflict, yes-no voting systems, political power, and social choice. The implications of each model presented, as well as the limitations of the model, are discussed. There is no mathematical prerequisite, but the course includes some algebraic computations and discussion of deductive proofs of the main results.
An introduction to cryptology, the science of sending, receiving, and intercepting secret messages. A variety of encryption methods are addressed, including classical substitution and transposition ciphers, as well as more modern methods such as symmetric-key algorithms and public-key cryptography. Though the focus is on the mathematical and computational aspects of encryption and code breaking, the class also discusses the history of secret codes, the role of cryptology in Internet security, and public policy issues related to secure communication and eavesdropping.
For students who intend to take calculus and need to acquire the necessary skills in algebra and trigonometry.
