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 be added to our mailing list, please contact Denise Marks.

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