PHY535 is an upper division laboratory involving experiments in optical, atomic and nuclear physics. In PHY535 you will (i) develop skills in conducting laboratory measurements and using laboratory instruments in optical, atomic and nuclear experiments, (ii) develop skills in data analysis and data interpretation including the careful evaluation of experimental uncertainties, and (iii) learn to effectively write-up your experimental work. Moreover, in PHY535 you will conduct experiments that were landmarks in the development of our modern, quantum-mechanical picture of the microscopic, sub-atomic world.
