About the Conference

The Gathering for Gardner conference, also referred to as G4Gn, is an invitation-only biennial conference held in Martin Gardner’s name, to celebrate recreational mathematics, magic, puzzles, skepticism, science, art, literature, and the intersections of these subjects. At the Gathering, attendees share their delight through presentations, exhibits, exchange gifts, performances, and original papers.

If you wish to attend and haven’t received an invitation, read the section How can I attend?

Martin Gardner was responsible for introducing mathematics in such a way to make it engaging, inspiring, and approachable. His Scientific American column Mathematical Games, which was based on recreational mathematics, was for 25 years the most popular feature of the magazine. It captivated  the imagination of young people and the young at heart.

The Gathering takes place over the course of five days (Wednesday through Sunday). Many of the participants give short presentations. The talks are on a wide variety of topics that Martin Gardner and his readers would have enjoyed. There are also optional Special Events: dinner and entertainment on Friday and Saturday evenings, and on Saturday the traditional event featuring mathemagical sculpture building and socializing.

The enthusiasm and diverse interests of participants make G4G a truly unique conference. Past attendees include professional and amateur mathematicians, magicians and skeptics, as well as performers, artists, educators, puzzlers, scientists, and anyone who is inspired by the same interdisciplinary curiosity that excited our namesake, Martin Gardner. Due to the high level of interest in the previous Gathering, we have expanded G4G15 to accommodate 400 attendees.

Giving a Presentation

To submit a talk, go to the registration website (find the link in your invitation email) and click on “Your Submissions”.

Attendees are encouraged to propose a talk, but it is not required; there are many other ways to contribute to the conference. There are generally more talk submissions than available slots, so some presentations may be placed on a wait list.

The deadline for talk submissions is December 15th, 2023. This gives us time to review submissions and plan the program. You can continue to submit revisions to your talk abstract up until the event, but your initial submission must be received by the deadline. 

Most attendees have 5 or 6 minutes for their presentation. A few speakers are given longer-slots for special circumstances.

The Gathering format features short talks, which allows many attendees to share their interests. The short-talk format allows attendees to get a quick introduction to many topics and then to follow up with speakers during the many social moments of the Gathering.

Because all talks are submissions by attendees, developing the schedule is an ongoing process right up until the event. We will email the schedule to all attendees a few weeks in advance of the conference and will provide an addendum of any last-minute changes at the event.

We rely on support from the friendly and helpful Ritz-Carlton AV Team and our volunteers. Presenters will alternate between two podium-mounted laptops on the stage. We also provide an Elmo Projector for close-up demonstrations. There are two projection screens, one on either side of the presentation stage. The AV staff will assist with loading your presentation from a thumb drive to the stage laptops or connecting to your personal laptop.

Location & Travel

The G4G15 conference will be held at the Ritz-Carlton in Atlanta, Georgia:
181 Peachtree Street N.E, Atlanta, GA 30303

If you don’t live near Atlanta, the easiest way to get to G4G15 is to fly to Hartsfield–Jackson Atlanta International Airport (ATL). From there you can rent a car and drive to the Ritz, take the Atlanta subway (MARTA), or take a taxi, Lyft, or Uber to the Ritz-Carlton. 

Be aware that the Ritz only offers valet parking. There is limited street and paid parking around the Ritz, so please plan accordingly if you intend to rent a car. 

The subway (MARTA) regular fare is $2.50 for a one-way trip. Fare must be added to a reloadable Breeze Card ($2) or a $1 disposable paper ticket. You can purchase the fare card or ticket, along with fare, at all MARTA rail stations or online. To get from the airport to the Ritz on MARTA, take the red/yellow line to Peachtree Center. This is the only train from the airport and it only goes in one direction from here, so it’s pretty easy to find your way. The MARTA exit at Peachtree Center is about two blocks from the hotel.

  1. An unpaid guest will receive a badge, can view the Sales and Exhibit Rooms, can attend the Special Events (dinner / entertainment) with a paid ticket, but cannot attend the presentations in the main ballroom. This is a good option for a significant other or friend who wants to spend time with you in the evenings but isn’t as interested in the conference content.
  2. A paid guest receives all the same access as an unpaid guest, plus they can attend the conference presentations. Registration for a paid guest is the same as for the conference attendee with add-ons available for dinners and entertainment.

G4Gn is an invitation-only conference; however, you can nominate yourself or others for attendance. If you are interested, please fill out the nomination form and be sure to mention the nominee’s background, passion for Martin Gardner’s legacy, and desire to engage with the community. We will be reviewing nominations periodically and will let you know if your nomination is accepted.
