About Celebration of Mind Celebration of Mind (CoM) brings people together to explore and enjoy puzzles, games, math and magic. Developed by the Gathering 4 Gardner Foundation, worldwide events are held annually on or around Martin Gardner’s birthday (October 21st) so that people can meet and share in the legacy of this polymath. As Gardner said, you can learn more when you’re in a state of entrancement, and that’s our guiding principle. CoM events and materials are designed to inspire, delight and awe. As new content is presented it’s added to our online repository of resources which is accessible to all and continues to inspire new generations to discover a range of intellectual pursuits. Find a Local Event Host a New Event A Worldwide Celebration After Gardner’s passing in 2010, his friends and readers began the tradition of hosting annual events on or around his October 21st birthday. Since then there have been hundreds of Celebrations from Helsinki to Antarctica, Bombay to Silicon Valley, all sharing in Gardner’s many interests. Some Celebrations attract hundreds and others are designed for just a handful but all are centered around activities that inspire and awe – logic puzzles, hexaflexagons, Möbius strips, magic illusions, card tricks, and visual paradoxes to name a few. Anyone who loves puzzles, math, Lewis Carroll, critical thinking, and an intellectual challenge is invited to participate in an event in their area, or to host a Celebration of their own. We offer resources for finding a local event, as well as plenty of activities for potential hosts, teachers, parents, or anyone just looking for some fun brain stimulation. Gathering 4 Gardner Foundation The Gathering 4 Gardner (G4G) Foundation stimulates curiosity and the playful exchange of ideas and critical thinking in recreational math, magic, science, literature, and puzzles to preserve the legacy of writer and polymath Martin Gardner. Celebration of Mind is a program developed and sustained by the G4G Foundation.
