## Colm Mulcahy – Inspired by Math #32

I had the pleasure of interviewing mathematician and mathematical card magic innovator Colm Mulcahy. Dr. Mulcahy just published a book, Mathematical Card Magic: Fifty-Two New Effects.

We spent a delightful hour discussing his book, his love of math and magic, and the inspiration behind writing the book. Plus, Dr. Mulcahy shares a few challenges listeners might enjoy chewing on, sprinkled throughout the interview. And, we discuss Martin Gardner, who Colm Mulcahy knew for the last decade of his life and met with several times.

You may also enjoy Shecky's text interview with Colm Mulcahy at Math Tango.

Enjoy!

## About Colm Mulcahy

From http://cardcolm.org/Bio.html

Colm Mulcahy is professor of mathematics at Spelman College, in Atlanta, where he has taught since 1988. He trained in algebra, and has also written papers on CAGC and wavelets. Over the last decade, he has been at the forefront of publishing original "mathemagical" principles and effects, 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.

He's particularly active in Gathering for Gardner and the associated Celebration of Mind initiative, and getting more involved in Maths Week Ireland and Julia Robinson Mathematics Festival outreach activities.

In 1997, Dr. Mulcahy received the MAA's Allendoerfer Award for excellence in expository writing, for an article on wavelets from Mathematics Magazine (Dec 1996). His interests include algebra, number and geometry. He earned a B.Sc. and M.Sc. in mathematical science from University College Dublin, in his native Ireland, and a Ph.D. from Cornell University for research in the abstract algebraic theory of quadratic forms.

## About Mathematical Card Magic: Fifty-Two New Effects

Mathematical card effects offer both beginning and experienced magicians an opportunity to entertain with a minimum of props. Featuring mostly original creations, Mathematical Card Magic: Fifty-Two New Effects presents an entertaining look at new mathematically based card tricks.

Each chapter contains four card effects, generally starting with simple applications of a particular mathematical principle and ending with more complex ones. Practice a handful of the introductory effects and, in no time, you’ll establish your reputation as a "mathemagician." Delve a little deeper into each chapter and the mathematics gets more interesting. The author explains the mathematics as needed in an easy-to-follow way. He also provides additional details, background, and suggestions for further explorations.

Suitable for recreational math buffs and amateur card lovers or as a text in a first-year seminar, this color book offers a diverse collection of new mathemagic principles and effects.
