"Please join Celebration of Mind at Stanford
A gathering for people of all ages who find enjoyment in recreational mathematics
Sunday, November 1, 3:00-5:30 PM, Cubberley Auditorium, Stanford
Free and open to the public
This event is part of a global celebration held to honor the legacy of recreational mathematician Martin Gardner, a renowned author of popular mathematics, and this year marks the 100th anniversary of his birth. The program consists of short talks in mathematics and related field presented in Cubberley Auditorium (directions and parking information below), followed by mathematical puzzles, games, and other activities in the Cubberley Lobby.
The program includes talks by professional magician Jordan Gold (including magic tricks), NY Times Numberplay blogger Gary Antonick, puzzle designer Scott Kim, Math Dance co-director Karl Schaffer, the Grabarchuk Family puzzle creators, and ZomeTool guru Scott Vorthmann.
The event is sponsored by Stanford Pre-Collegiate Studies, and is organized by Stan Isaacs and Rick Sommer.
For directions see: http://web.stanford.edu/dept/HPS/CubberleyDirections.html. Note that parking permits are not required in "A" and "C" parking spaces on Sundays.
Noted for making mathematics accessible to general audiences, Gardner was known for works from a column in Scientific American to the classic Lewis Carroll reference The Annotated Alice. Even those who don't recognize his name will be familiar with ideas he helped popularize, from the work of MC Escher to flexagons and a method to determine the day of the week on a particular date. In order to commemorate his accomplishments and spirit, Celebrations of Mind are held all across the globe. For more information and to find a Celebration near you, visit www.g4g-com.org.
