I always enjoy sharing the beauty of mathematics with others, whether K-12 students, undergraduates, MAA meetings or public lectures. Recently the most commonly requested talks have been Spherical Cats and Ham Sandwiches, a visual introduction to topology which can be modified for all audiences, and a behind-the-scenes look at Möbius Transformations Revealed (see below).
I have a long-standing interest in mathematical visualization and its use in the classroom. Links to various projects:
I frequently supervise CLA senior projects, usually (but not always) with students who have taken a class with me and with whom I share some mathematical and/or educational interests. Students can always contact me to discuss potential projects.
I also lead research projects with students, particularly UMTYMP students and alumni. See this paper for an example.
Möbius Transformations Revealed is an award-winning short film by Doug Arnold and myself which has been viewed nearly 2 million times on YouTube alone. We originally created it for the 2007 Science and Engineering Visualization Challenge, sponsored by the NSF and Science Magazine. It has been featured in a number of articles and websites, including:
A short clip of the movie is included in the film Achieving the Unachievable, a documentary about M.C. Escher's Print Gallery.
Go to the movie download page to watch the film and for more links to press coverage.
Möbius Transformations Revealed is a wonderful video clarifying a deep topic. This is amazing work by Douglas Arnold and Jonathan Rogness of the University of Minnesota. Edward Tufte
