A selection of historically important experiments from atomic and nuclear spectroscopy, particle physics, solid-state and low-temperature physics performed with modern instrumentation. Each student does three experiments, usually with a partner. As students progress, they are encouraged to pursue independent projects, without rigid formats or procedures. The emphasis is on the development of experimental skills and on individual, ethical, professionally acceptable analysis and presentation of results, both orally and in writing. Two three-hour laboratory sessions per week. This course has an associated fee. Please see www.stonybrook.edu/coursefees for more information.
