Mathematics is one of the oldest learned disciplines, and continues to be a vital and developing topic of research. It is the basis for understanding much of the physical world, and it has become essential for the study of modern developments in the social sciences. Mathematics graduates are very much in demand in teaching, the business world, and the computing professions. The Vassar Mathematics Department offers a flexible major, enabling students to tailor their course of study for a range of interests, as well as a correlate sequence for students concentrating in other disciplines. Our biweekly colloquium, the annual Asprey Lecture, and participation in URSI offer opportunities to get a glimpse of the living subject that is present-day mathematics.
