Wellesley College has a long tradition of providing high-quality scientific training in the context of a liberal arts education. The Physics Department is an integral part of that tradition. The contemporary study of the physical universe encompasses systems ranging from the microscopic - atoms, nuclei, and elementary particles, to the very large - planets, stars, and galaxies. A central theme of all branches of physics is the search for unifying principles underlying the diverse phenomena of nature. Wellesley offers a full range of academically demanding courses that constitute a strong physics major and small classes that allow for individualized attention.
