G4G Celebration
Gathering 4 Gardner (G4G) is a conference, a foundation, and a community of people who share some of Martin Gardner’s many interests, which include recreational mathematics, puzzles, magic and skepticism.
Celebration of Mind (CoM) is a worldwide series of events held on or around Gardner’s birthday: October 21st. Anyone, anywhere, can host a CoM event, and most are open to the public. These CoM events vary in size from three people meeting to perform rubber-band magic for each other, to crowds of hundreds of students in highly organized exploratory paper folding activities.
