Description:

What makes a violin sound different from a piano or a clarinet? We will explore the differences between musical pitches and timbres by using wave theory from physics. The objective of the course is for students to see how physical principles can be used to explain the world around them. Wave theory will be applied to two very different topics, one classical and one modern: music and quantum mechanics. The course will use physics to study the properties and production of musical sounds. A wide variety of physics demonstrations and musical instruments will be used to reveal physical properties and stimulate discussion. Finally, modern quantum mechanics and its dependence on wave theory will be used to explain the operation of the scanning tunneling microscope (STM), a scientific instrument which is used to image individual atoms on a surface. Atomic scale images produced by this microscope are relevant to the fabrication of small structures for integrated circuits which make possible new technological advances in computers.

 

Seminar Goals:

Students will work to develop effective communication skills through two presentations and the final paper. One presentation will be the description of the operation of a computer component, and the other is the presentation of the final project, which is the design and construction of a musical instrument. Students will also develop their writing skills by writing a final paper that describes the final project in detail. Students will develop high cognitive skills and prepare for lifelong learning by applying the scientific method to determine the design of the final project. They will understand the relationship of physics concepts, such as frequency, amplitude and wave shape of sound waves, to musical properties such as pitch, loudness, and timbre. They will learn why different instruments playing the same note sound different to one’s ears, how musical scales relate to the mathematical ratios of frequencies of sound waves, and how the construction of different musical instruments relates to their production of varying sounds. Physical principles will also be used to understand the operation of stereo sound systems, parts of a digital computer and how they operate, digitized computer music, the operation of the STM, and how fabrication of small structures applies to high technology devices.
