Fun with Physics and Music

There is a wealth of physics and mathematics in the world of music, from the way musical instruments work to the composition of music that is pleasing to the ear. Rhythm involves common denominators and standing waves in strings, membranes or other surfaces. The Do-Re-Mi scale is based on an exponential progression possible with strings, air columns, tubes and other physical structures. Some melodies are constructed using plane geometry, while others use reflections. Satisfying harmonies rely on rational numbers. This session will be partly demonstration and partly hands-on construction, tuning, and performance of your own musical instrument.

Biography

Rolly has been a member of the OAPT for all but one of its years in existence. He has served as Contest Author and as Section Representative to the AAPT, and currently serves as web site co-manager. Rolly taught physics and mathematics in the Niagara area for 28 years. He finished his teaching career as head of mathematics at Ridgeway Crystal Beach High School in Ridgeway, Ontario. After retiring from the classroom in June of 2001, he spends his some of his time authoring and otherwise contributing to mathematics textbooks for McGraw-Hill Ryerson, and pursuing his many hobbies, including flying, traveling, scuba diving, playing the piano, reading, canoeing, and motorcycling. Rolly obtained his B. Sc. in physics from the University of Windsor, his M. Sc. in physics from the University of Waterloo, and his B. Ed. from Queen's University. Rolly remains a member and strong supporter of the OAPT. His goal is to reach 100 while still a member.
