Mathematics
Explore the art of logic and problem solving.
Develop a Sought-After Quantitative Skill Set
Core Ideas and Collaboration
Oberlin Mathematics Professor Jack Calcut helps students grasp the core ideas behind a proof before translating those ideas into mathematical language.

Creativity and Structure
Math students learn to combine imagination with logic. In Professor Bob Bosch’s seminar students make the connection literal, using mathematics to create art.

Featured Courses
Cryptography
Explore the science of making and breaking secret codes. We start with codes that Julius Caesar would have used in his armies. To make more sophisticated codes, we need to learn about a branch of mathematics called number theory. These tools will help us understand the modern cryptosystems (like RSA) that the internet is built on.

Discrete Mathematics
Mathematics is a language, and this class teaches you to “speak math.” We introduce topics you will not have seen in calculus (such as logic, sets, induction, number theory, combinatorics, graph theory) and emphasize creative problem solving and proof writing. At the end, you will be prepared to tackle many of our upper level offerings.

Probability
Dealing with uncertainty is critical in many applications of mathematics. For example, it is important in machine learning, statistical modeling, economics, actuarial science, and physics. This class uses the tools you’ve learned in 200 level classes to give uncertainty and probability a firm mathematical foundation, ready to be applied to other fields.

Harmonic Analysis
Ever since the imperfections of Pythagorean tuning gave evidence for the existence of irrational numbers, music has inspired important developments in mathematics. We start with these classical results and work our way towards modern methods like the Fourier transform, with its applications to acoustics.

Student Profiles
Particle Systems as Epidemics
Garrett Robins '21, a Mathematics major, has been researching the behavior of particle systems to model the diffusion of disease and opinion.

The Future of Sustainable Buildings
At Oberlin Grant Sheely ’19, a math and physics double major, was captain of the cross country and track and field programs. He now works as a sustainability coordinator at Vornado Real Estate Trust in New York City.

National Science Research Fellow
Alongside Professor Susan Jane Colley, Margaret Nichols '13 did senior honors work as a mathematics major. With the support of a fellowship from the National Science Foundation, she went on to pursue a PhD in math at the University of Chicago.
