Kresimir Josic of Boston University discusses the mathematics of musical instruments at a seminar on Friday, Feb. 4, from noon to 1 p.m. in Room 206 of Science & Tech I. Sponsored by George Mason’s Nonlinear Science Group, the lecture should be of interest to both scientists and the general public.

In his presentation, Josic discusses the reason that the chromatic scale is composed of 12 semitones. “The explanation is just one of the instances in which music meets mathematics in a non-obvious and interesting way,” he says. In addition, he discusses how this explanation leads to other, still-unanswered mathematical questions about music.

The Nonlinear Science Group is a multidisciplinary group of scientists who focus on the study of complex nonlinear phenomena in a wide range of physical, biological, and mathematical systems. The group consists of faculty members and students from the Krasnow Institute for Advanced Study; the Departments of Physics and Astronomy, Mathematical Sciences, and Psychology; and the Institute for Computational Sciences and Informatics.
