G4G14 has been rescheduled for Wednesday, April 7th through Sunday, April 11th, 2021. The event will be held at the Ritz-Carlton in Atlanta, Georgia. By default, if you registered for G4G14, your registration will automatically transfer to the new dates (as per the terms of registration).

Due to the situation with COVID-19, most communities have taken aggressive action to limit public gatherings, most academic institutions have banned nonessential travel, and travel between countries has been prohibited or limited. Therefore, it was impossible to hold the conference during its originally scheduled dates. This decision was not made lightly, and our primary consideration was the health and safety of our attendees, staff, volunteers, and vendors. Please accept our humble apologies for this unfortunate postponement.

14th Gathering 4 Gardner Conference (2021)

From Wednesday, April 7th through Sunday, April 11th, 2021 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

Come join the fun, the mystery, and the challenge of playing a variation of Robert Abbott’s card game Eleusis! (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). 

Featured Presenters

G4G is pleased to announce three Featured Presenters for the 2021 Gathering conference. Each presenter will give two talks: one private talk as part of the regular programing of the conference for G4G attendees exclusively and one free talk open to the general public (no tickets needed).

Moon Duchin

Tufts University, Associate Professor of Mathematics

Moon’s Bio: Moon Duchin is an associate professor of mathematics at Tufts University and a historian of science.  She founded the Metric Geometry and Gerrymandering Group to use geometry and computation to study gerrymandering, believing it to be a fundamental threat to democracy.  She is a Fellow of the American Mathematical Society, and in 2018 was awarded a Guggenheim fellowship.

Public Presentation:  
“Graphs, Geometry and Gerrymandering”

Location: Georgia Tech, Kendeda Building Auditorium
422 Ferst Dr NW, Atlanta, GA 30313
Date: TBA
Time: TBA

Abstract: The theory of random walks has found a fruitful application in electoral redistricting by allowing us to sample from the partitions of a state into districts. By comparing a plan to neutral alternatives, we can measure the extent of gerrymandering—when one party takes advantage of the authority to draw the lines. I’ll discuss some surprisingly simple questions about graphs and geometry that can help us make advances in policy and civil rights.
G4G14 Program Talk: 
“Redistricting and the Universe of Possibility”

Location/Date/Time: Open to G4G14 Conference Attendees Only
(talk schedule TBD)

Abstract:A small districting problem: divide a 6×6 grid into six connected “districts” of equal size. There are roughly a half-million ways to do this. A medium-size districting problem: divide the 9059 precincts of Pennsylvania into 18 connected districts of equal population. There are unthinkably many ways to do this. And then there are the big problems…… I’ll give you a tour of (what we know about) the shape and the character of the wild universe of districting plans.
Mark Burstein

Mark Burstein

Lewis Carroll Society of North America (LCSNA) 

Mark’s Bio: Mark Burstein is a lifelong Carrollian, a dire condition he inherited from his father, along with their world-class collection. A book editor by profession, over the years he had created, edited, or contributed to twenty-one books by or about Lewis Carroll, including updating, editing, and art directing Gardner’s The Annotated Alice for the “150th Anniversary Deluxe Edition” (W. W. Norton, 2015), and Alice’s Adventures in Wonderland illustrated by Salvador Dalí (Princeton, 2015). He has served the Lewis Carroll Society of North America (LCSNA) as its president, publications chair, and longtime editor of its magazine, Knight Letter.

Public Presentation:  
“What IS It about Alice?”  

Location: Decatur Presbyterian Church
205 Sycamore St, Decatur, GA 30030
Date: TBA
Time: TBA

Abstract: Why is Alice in Wonderland, along with the other Alice books, so prevalent in our culture and around the world? Why is Alice the most quoted and widely illustrated novel in English, as well as one of the most translated. This richly illustrated talk also makes diversions into the life and times of Lewis Carroll, and the story of one of his modern devotees.

G4G14 Program Talk:
“A Literary Englishman and the Scientific American: Lewis Carroll’s Appearances in ‘Mathematical Games”

Location/Date/Time: Open to G4G14 Conference Attendees Only
(talk schedule TBD)

Abstract: Lewis Carroll, the nom de plume of the Rev. Charles L. Dodgson, a mathematics lecturer at Oxford, was also an innovator in recreational mathematics, magic, puzzles, cryptography, and inventions. His appearances in Scientific American began with mathematician Warren Weaver’s article in April 1956, and his name is mentioned over a hundred times in fourteen of Martin Gardner’s “Mathematical Games” columns. Using these as a springboard, topics will also include Carroll himself, the Wonderland/Looking-Glass dyad, Gardner, and their intertwining in The Annotated Alice.

Abstract: How do you tell stories about science? Paula Apsell will discuss the art of science communication on television and online. Using clips from the internationally acclaimed series NOVA, she will share how complex scientific ideas are made not only accessible, but compelling to a wide range of viewers.

G4G14 Program Talk:
“Science, History and Truth”

Location/Date/Time: Open to G4G14 Conference Attendees Only
(talk schedule TBD)

Abstract: We live in a time of great misunderstanding of science, a time when science is under attack, when facts are fungible, when truth isn’t always truth. Frightening as this is, it’s tempting to think of it as something new, but sadly it’s not. History is full of anti-science movements.The need for informed debate is more urgent than ever: We have no choice. We cannot leave science to the experts. We — all of us — have to become citizen scientists.

More offsite activities to be announced.

Evening Entertainment

Thursday and Saturday 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).
