My focus is teaching entry-level courses in the sciences that are as accessible, engaging, and un-intimidating as possible, while still providing solid grounding in physics concepts, mathematical reasoning, and problem solving. I am interested in developing and supporting programs which make the natural sciences more accessible for under-represented groups; as such, I am the co-director of the Bowdoin Science Experience, a pre-orientation program designed to help incoming 1st year students from under-represented groups who are interested in the sciences.
Physics 050 Physics of Musical Sound
This course explores “how music works” from a physics point of view – what generates sound, how it propagates, and how it is measured and characterized. Although we focus primarily on the physical “laws” describing sound, the study of musical sound (or musical acoustics) is actually an interdisciplinary subject that includes the physiology of the ear, the psychology of how the brain interprets the ear’s signals, and some elements of music theory. The course starts with basic elements of acoustics, and then continues by studying the particular sounds of various types of musical instruments and the human voice.
