Mathematical Card Magic

Colm Mulcahy is a professor of mathematics at Spelman College. Over the last decade, he has been at the forefront of publishing new "mathemagical" principles and effects for cards, particularly in his long-running bi-monthly Card Colm for the Mathematical Association of America (MAA). He also blogs at the Aperiodical and the Huffington Post. Dr. Mulcahy has been a recipient of the MAA's Allendoerfer Award for excellence in expository writing. His interests are broad, ranging from algebra and number theory to geometry. He earned a B. Sc. and M. Sc. in mathematical science from University College Dublin and a PhD from Cornell University for research in the algebraic theory of quadratic forms.
