With the late Martin Gardner, in Oklahoma, Mar 2007. The famed writer was a sweet, unassuming and generous man. He played a significant role in enriching the intellectual climate of a nation during the space race era, turning tens of thousands of people on to the joys of creative thinking. In a sense, he did for mathematics what Julia Child did for French cooking. His legacy is celebrated every Oct with Celebration of Mind parties worldwide.

With Ethan Brown, in NYC, Aug 2013, at the first MOVES conference at the groundbreaking Museum of Math. Though he's only starting 9th grade, Ethan is already an energetic blogger, and a protégé of Art Benjamin. He's a total whiz at magic square completion and can do amazing mental arithmetic feats.

With Ron Graham and Persi Diaconis, in San Diego, Jan 2013, at a book signing for their beautiful and inspirational Magical Mathematics: The Mathematical Ideas that Animate Great Magic Tricks (Princeton University Press, 2011) deservedly won the 2013 2013 Euler Book Prize. The wonderful mathematics and magic in that tome is much more sophisticated than that found in Mathematical Card Magic: Fifty-Two New Effects.
