Welcome and thanks for visiting my web site! My academic activities center on the history of mathematics, so included here is information related to my teaching and research in this area. My research interests in the history of mathematics include ancient Greece and medieval Islam, as well as the history of such scientific instruments as the sundial and the astrolabe. Sundials are a particular interest of mine so they have their own section here.
Among the courses that I teach at Simon Fraser University, are calculus, geometry, linear algebra, history of mathematics, and mathematics in science and civilization.
To explore this site, please use the menus that pop up over the sundial numerals.
