Department News

The Department of Mathematics and Statistics has an annual newsletter, The Quaternion, in which we report news of the department (as a whole, and of individual members). Each issue also has a feature on a topic in mathematics and/or statistics, mathematics education, or something else of interest to the math/statistics community. The newsletter is distributed in late August or early September.

If you would like to respond to an article, or discuss other Quaternion-related matters, please contact the editor, Greg McColm.
