Chemistry is often known as “the central science” because of the key position it occupies in modern science and engineering. Most phenomena in the biological and earth sciences can be described in terms of the chemical and physical behavior of atoms and molecules, and chemical principles also underlie much progress in medicine and engineering. For these reasons, chemistry is a natural and useful minor for students majoring in other science and engineering disciplines. The Chemical Sciences minor allows students to pursue interests in chemistry in some depth without requiring the breadth of course work and extensive laboratory time required for the Chemical Sciences major.
