The 13th Biennial Gathering 4 Gardner Conference (2018)

On April 11th through the 15th, 2018, G4G will “gather” together bright and inquisitive minds in recreational mathematics, magic, puzzles, skepticism, science, art, literature, and the intersections of these subjects.

The conference will feature lectures, performance art, puzzle and book displays, close-up and stage magic acts, and guided sculpture building. Traditionally, each conference has a Gift Exchange in which attendees swap puzzles, magic tricks, artwork, papers, novelty items, books, etc.

Unlike many other conferences, G4G is participatory in nature; all attendees are encouraged to contribute to the community, whether that be a 5-minute presentation or performance, an original paper, a unique exhibit or a novelty item for the gift exchange. This spirit of participation ensures attendees leave with more connections, ideas and inspiration than when they arrived.
