14th Gathering 4 Gardner Conference (2022)

From April 6-10, 2022 in Atlanta, Georgia, G4G participants will assemble, in Martin Gardner’s name, to celebrate recreational mathematics, magic, puzzles, skepticism, science, art, literature, and the intersections of these subjects. Participants will offer presentations, performances, original papers, and exhibits. Countless exchanges of ideas and examples of magic will inspire and delight. Unlike many other conferences, G4G is participatory in nature; all attendees are encouraged to contribute, whether that be a 5-minute presentation, an original paper, a unique exhibit, or a novelty item for the gift exchange.

Eleusis Express Tribute Tournament

(pronounced el-you-sis) Featured in the Martin Gardner Mathematical Games columns of the June 1959 and of the October 1977 Scientific American. We’ll play Eleusis Express, a quick-play adaptation approved by Robert, led by John Golden (the adapter).

Offsite Activities

Sarah Garvin Rodgers invites the G4G community to her art gallery, Different Trains, in the artistic Old Depot District of Decatur. On Saturday the 9th, we are pitching tents in the street, serving lunch, building mathematical sculptures organized by George Hart, and creating opportunities for participants to socialize and explore this vibrant community.

Description of Activities

A Mathematical Walk Around Downtown Decatur

Join Ron Lancaster for a walk in downtown Decatur to experience viewing the world through a mathematical lens while getting some exercise. This offsite event will be an opportunity to work with others to answer questions and solve puzzles related to daily life, design, art, architecture, science and recreational mathematics.

Ron is an Associate Professor (Teaching Stream) at the University of Toronto where he teaches mathematics courses for pre-service middle and high school teachers. He has over 20 years of experience teaching grades 7 through 12 mathematics. Ron’s professional activities include consultations and conference presentations in North America, Asia, England, the Middle East, Africa, India and Europe. Ron is an author for the NCTM (The Mathematical Lens) and member of the Advisory Board for the Museum of Mathematics in New York City. He is the recipient of the 2015 Margaret Sinclair Memorial Award Recognizing Innovation and Excellence in Mathematics Education awarded by the Fields Institute.

More offsite activities to be announced.

Evening Entertainment

Thursday and Friday evenings at the conference are times to further connect. A buffet dinner will be served followed by entertainment featuring eclectic performances. Past shows have included close-up and stage magic and variety-style acts from juggling to feats of strength and mental math. This is also a wonderful opportunity to meet the other attendees.

Gift Exchange

Traditionally, every Gathering conference includes a Gift Exchange in which attendees swap puzzles, magic tricks, artwork, papers, novelty items, books, etc. Participants in the exchange must submit an item for the physical Exchange Bag or a document for the Exchange Book. If you’re looking for inspiration, think of the exchange as something you would be excited to share with Martin Gardner himself. We recommend something original or unique, something made by hand, or something other attendees would enjoy or value. 

Everyone who participates in the Exchange will receive:

  • G4G14 Exchange Bag
  • G4G14 Exchange Book

Sales Room & Exhibit Room

At G4G14, attendees will have the option of setting up a table in the Sales Room and/or the Exhibit Room.

Sales Room: If you are a vendor and wish to sell items to other G4G attendees (examples: books, sculptures, puzzles, mathy toys, etc.) consider reserving a Sales Table. Only attendees registered for a Sales Table will be permitted to sell their inventory at the conference.

Exhibit Room: If you have something special to share with the G4G community that is either too large or complex to be reproduced for the gift exchange, consider reserving an Exhibit Table. Past exhibit examples include: surprising 3D-printed objects, unusual musical instruments, kinetic sculptures, historical collections, and special edition books, toys, and games.

For both the Sales and Exhibit Room, space is limited and tables are available on a first-come, first-served basis. Sales and Exhibit Room participants are required to staff their table during Happy Hour on EVENT EVENING TBA (from the end of the final talk of the day until the start of dinner).

Nominate Attendees

You are welcome to nominate new attendees (including yourself) for invitation to G4G14. Please let us know how your nominee will enrich the G4G community. Fill out the form once for each person being nominated.
