Physics forms the intellectual core of the physical sciences. It examines the world through an analytical lens: providing insight into the fundamental building blocks of nature, the emergent behavior of complex systems, and the laws which govern the physical world. In addition to offering an exciting array of courses, Cornell's Department of Physics features world-class research in a wide variety of specializations, from biophysics and nanoscience to high energy physics, accelerator science and string theory. Undergraduates in physics have the opportunity to conduct research in these areas, as well as participate in teaching and community outreach activities.
