We’ll meet up on Zoom!
– Socializing &
Discussion –

12 noon Atlanta time every Sunday

We are now using Zoom (at a new URL, see the blue button below) as a way to mingle and chat each Sunday at 12 noon Atlanta time, to exchange ideas on a given theme. This replaces the themed session we used to have at the same time on Saturdays in Gathertown (Note: that space is still open, 24/7, for G4G community members to meet in informally, with a cap of 10 participants).

Please join us starting 5 minutes before each session using the following button:

Theme – The themes will change each week and are announced in our Friday News. If you are interested in spearheading one such themed session contact us via support@g4gfoundation.org.

Pencil & Paper Puzzlers
at 12 Noon Atlanta Time
Hosted by Vince Matsko
This forum will provide enthusiasts an opportunity to discuss the creation, solution, and layout of pencil-and-paper puzzles.  Our first meeting will focus on the format of these monthly meetings, which will include the critique of participants’ original puzzles by P&PP. Caveat: this forum will NOT be looking at traditional puzzles (like Sudoku, unless the creator adds an unusual twist), interactive puzzles (such as those done in a browser or on a phone), or 3D puzzles (like Rubik’s cube)
at 12 Noon Atlanta Time
Hosted by Érika Roldan

Can an outreach activity lead to research and vice-versa? Is it possible to do citizen science in mathematics through gamification? We will explore examples of creating activities and videogames based on open problems that Érika Roldan is leading the research group of Stochastic Topology and its applications at the Max Planck Institute for Mathematics in the Sciences, being affiliated with the Center for Scalable Data Analytics and Artificial Intelligence (ScaDS.AI) at Universität Leipzig.

Rediscovering Martin Gardner’s Mathematical Games column from Scientific American
at 12 Noon Atlanta Time
Hosted by Scott Kim

In November 1958 Martin Gardner chose Squared Squares as the subject of his Mathematical Games column and the 33 x 32 squared rectangle of Z. Moroń was featured on the magazine cover. William Tutte, best known for his work in graph theory and breaking codes in WWII, wrote an article for the column on how the square was squared by himself and his Trinity undergraduate colleagues, Brooks, Smith, and Stone. Tutte’s article in Gardner’s column had an electrifying effect on me when I was a teenager. I’ll discuss highlights of this wonderful column, and showcase the wonderful work of Stuart Errol Anderson who built a comprehensive site on this topic, as well as my own extensions to the problem.
