More Informal Information

I am a member of the American Mathematical Society and the Mathematical Association of America, among other organizations. I share my home with one husband (William C. Colley, III) and two cats, Pythagoras and Vinny, having said farewell to the T.G.V. in February 2000, 8-Ball in July 2007, Whitey in April 2010, Velcro in December 2017, and Tatters in April 2021.  Here are Velcro, Pythagoras, Tatters, and Vinny, rendered as fractals.

Some links I particularly like are the Geometry Center at the University of Minnesota, the MacTutor History of Mathematics site, and, for recreation, the Dilbert Zone.
