Requirements for a Major:
Prospective physics majors are encouraged to begin their study of physics and mathematics in the first year. Physics courses are strongly sequential and are developed in close association with mathematics courses. The curriculum provides an excellent basis for graduate study in physics, astronomy, and in various fields of engineering, and for careers in high-school teaching, industry, and other areas.
Required courses for the major are Physics 115 and either 113 or 114; followed by 128, 229, 230, 235, 336 and 338, 342, and 400, plus one applied physics course. (Choose from the following applied courses: Physics 234, 261, 341, 343, 344 or 354; Astronomy 232 or 233: or others upon consultation with the department.) Required math courses are Mathematics 111, 121, 211, and 232. Additional courses that are often recommended include Physics 123, 223, 350, 352, 353, 356, Astronomy 113, 356, Chemistry 123, Mathematics 241, 341, 351, and Computer Science 117.
Major Under Combined Plan in Engineering (See Engineering in index):
In addition to completing the requirements for the physics major listed above, the student should also take the following courses required for admission to the engineering schools: Mathematics 241, Chemistry 123, 230, and Computer Science 117. At the discretion of the department, the requirement of Physics 342 may be waived in some instances to allow the student more latitude in selection of courses.
Physics Courses (PHYS)
PHYS 100. Complexity and Chaos A complex system is one in which elements interacting with simple rules give rise to complicated global behavior, such as in ecologies or economies. In this class we will consider these systems from a physics perspective. We will begin by considering the basics of complexity theory (particularly issues of chaos, emergent phenomena, self-organized criticality, entropy and the second law of thermodynamics, evolution, etc). By the middle of the term, each student will choose a research topic (from physics, biology, ecology or economics, for example) that concerns complexity and pursue this individually.
