First-year students who have successfully completed the equivalent of Physics 100 at the college level may petition the physics department to take Physics 200 in their freshman year. The petition must offer evidence of proficiency in calculus-based electricity and magnetism. Lecture-conference-laboratory.

One-dimensional applications, including the infinite square-well, the harmonic oscillator, and scattering; in three dimensions, the theory of angular momentum, central potentials, and the hydrogen atom; time-independent perturbation theory, spin, identical particles, and the Pauli exclusion principle. In general, this course concentrates on exact solutions to artificial problems, in contrast to Quantum Mechanics II, which develops approximate solutions to real problems. Prerequisite: Physics 200. Lecture.

### Physics 351
- Thermal Physics

Full course for one semester. Examines the essentials of probability and statistics, the kinetic theory of gases, statistical mechanics, temperature, equations of state, heat, internal energy, entropy, reversibility, and distribution functions. Prerequisite: Physics 200. Lecture.

### Physics 363
- Molecular Biophysics

Full course for one semester. The course will cover the physics of measurement techniques for studying the most significant intermolecular interactions of synaptic transmission. An introduction to the biology of neurons will be provided. Measurement techniques such as evanescent wave microscopy, confocal microscopy, X-ray diffraction, fluorescence resonance energy transfer, and Raman and infrared spectroscopy will be explained in terms of the physics of the experiment and its implementation. A clear idea of how these measurements inform the models of cellular processes such as exocytosis as well as the atomic level models of neuromolecular structure and function will be presented. The course will include demonstrations of selected measurement techniques such as total internal reflection microscopy, infrared absorption, and crystallography. Prerequisites: Physics 100, Physics 200, Mathematics 211and 212. Lecture. Not offered 2007-08.

### Physics 364
- Selected Topics of Astrophysical Interest

Full course for one semester. Specific topics vary from year to year, drawn principally from the following areas: internal constitution, evolution, and death of stars; structure of galaxies; interstellar medium; radiative processes; and classical cosmology. Prerequisite: Physics 200. Lecture. Not offered 2007-08.

### Physics 366

The course includes a semi-historical overview, followed by relativistic kinematics, the Dirac equation, evaluation of simple Feynman diagrams, and a survey of the strong, electromagnetic, and weak interactions from the perspective of gauge theory. Prerequisite: Physics 200. Lecture-conference.

### Physics 367
- Scientific Computation

Full course for one semester. This course covers numerical and laboratory methods for students of science. The primary focus will be on topics in physics, chemistry, and biology. The course begins with the history and modern importance of scientific computation, moves on to methodology and specific algorithms, and closes with individual elective projects to be approved by the instructor. Basic programming will not be taught; the course will concentrate on scientific, not programmatic, aspects, so students must be able to write programs largely on their own. Specific topics include differential equations, matrix methods, signal and image processing, quantum-theoretic models, astrophysical models, and non-linear and chaotic systems. Prerequisites: a sophomore-level course in one of the sciences and experience with a sufficiently strong computer language, such as Pascal or C. Lecture-conference-laboratory.

Full course for one semester. A modern account of the classical dynamics of systems with infinitely many degrees of freedom. Treats both general principles and more specialized techniques appropriate to the analysis of topics of exceptional current interest (solitons, gauge fields). Although primarily for physicists, the course contains much material of interest to mathematicians. A good command of classical mechanics, linear algebra, and the theory of differential equations is assumed. Lecture. Not offered 2007-08.

### Physics 442
- Quantum Mechanics II

Full course for one semester. Content varies from year to year, but the course can be thought of as a continuation of Physics 342. The emphasis is on approximation techniques (time-independent and time-dependent perturbation theory, WKB approximation, variational principles, Born approximation), with applications to atoms, molecules, and solids, the quantum theory of radiation, and formal scattering theory. Prerequisite: Physics 342. Lecture.

### Physics 470

### Physics 481

One-half course or full course for one semester. Readings and laboratory work of an advanced character. Students choose some field in which they are interested; they are expected to become familiar with the special instruments and methods of that discipline. Open only to juniors and seniors, by consent of the instructor.
