The event map for the Gathering for Gardner Celebration of Mind 2012 is now live, with nine events already listed in North and South America and Europe. More will surely be added in time.
These are parties “to celebrate the legacy of Martin Gardner on or around Sunday, October 21, 2012 through the enjoyment of Puzzles, Magic, Recreational Math, Lewis Carroll, Skepticism and Rationality”. The website explains:
Celebrations can be large or intimate depending on the event. They don’t have to be formal and range from a few friends getting together to discuss the above all the way up to series of lectures at Universities and Science Cafes.
