The students in Experimental Analysis (PHYS 315) presented the results of several experiments in a semester-ending poster session. Topics included the charge to mass ratio of an electron, the speed of light, the Ideal Gas Law, the Stefan-Boltzmann law, electron diffraction and the Michelson Interferometer. Through these experiments, which reproduce breakthroughs in physics, the students developed a greater appreciation for the challenges of controlling environment, systematic errors and statistical errors.
