Within the department of Chemistry and Chemical Biology, there are three concentrations for undergraduate students. Chemistry is the science of the structure, properties, and reactions of matter. It is both a basic science, fundamental to an understanding of the world we live in, and a practical science with an enormous number and variety of important applications. Knowledge of chemistry is fundamental to an understanding of biology and biochemistry and of certain aspects of geology, astronomy, physics, and engineering. The Chemistry & Physics concentration is structured to assure that all concentrators are introduced to the core subjects of chemistry (organic, inorganic, and physical); of physics (mechanics, electromagnetism, and quantum theory); and of mathematics. Beyond this core, students take additional courses in chemistry, physics, or related sciences, according to their personal interests and objectives. The Chemical and Physical Biology (CPB) concentration provides students with a broad foundation in the physical and life sciences. This concentration is designed for students interested in applying quantitative tools, physical concepts, and chemical principles to the study of biology.
