The Card Colm bimonthly column is sponsored by the Mathematical Association of America (MAA) and it explores mathematical card principles and effects for fun. It's an inspired idea ignited by the musings and mediations of Martin Gardner, a man who loved such things. The column is penned by Colm Mulcahy who, when not enjoying card tricks, can be found teaching at Spelman College. The posts have titles like "Never Forget a Face (Double-Dealing with a Difference)" and "Predictability Outranks Luck." Each post contains fun diagrams, witty asides, and links to other references. People with an interest in probability, card games and mathematics in general will find much to enjoy here.
