The 14th Biennial Gathering 4 Gardner Conference (2020)

From Wednesday, March 25th through Sunday, March 29th, 2020 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.

Four Days of Presentations

G4G offers opportunities for participants to share their passions and discoveries. The core of the conference consists of 4 days of brief presentations (generally 5 to 6 minutes). Check back on this web page for announcements of featured G4G14 presenters. Featured Presenters at the previous Gathering (G4G13) were Ernő Rubik, Doris Schattschneider, and Manjul Bhargava. G4G14 Featured Presenters to be determined.

PLEASE NOTE: There are no presentations on the afternoon of Saturday, March 28th. The offsite Special Event will be taking place at that time. All G4G14 attendees may participate in the offsite event with a purchased ticket. 

Offsite Activities

Due to the success of the offsite event at the previous Gathering (G4G13), we have decided to again hold the event in Decatur, Georgia.

Sarah Garvin Rodgers invites the G4G community to her home and art gallery, Different Trains, in the artistic Old Depot District of Decatur. On Saturday the 28th, we’re 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. As the sun sets, attendees will enjoy a Happy Hour reception inside Color Wheel Art Studio.

PLEASE NOTE: The offsite for G4G14 will be held on SATURDAY March 28th, 2020.

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 Thursday evening (from the end of the final talk of the day until the start of dinner).
