08 Fold out the wallpaper pattern
October 21, 2021 at 4:00 a.m. Beijing time
Description: This lecture will introduce an example of exploring wallpaper groups through the origami process. The folding techniques of tessellation patterns (and other symmetrical patterns) will begin with a brief introduction, including some basic movements that can be combined to produce patterns with an arbitrary intricate visual degree. We believe that inlaid origami provide a particularly effective mechanism for exploring wallpaper groups, as they (inlaid origami) often allow for manual implementation (and reverse) physical changes to change the symmetry group, which requires only one sheet of paper and no more equipment. Mental and tactile experiences that recognize and perform this change may help identify potential symmetrical structures. Quickly and simply adjusting the crease chart can cause changes that are mathematically significant (e.g., eliminating reflections while preserving rotational symmetry), or changes that retain the original wallpaper group but have a significant change in appearance. The presentation will introduce some of the key concepts of wallpaper group classification, but will focus on playing on paper.
Speaker: Rachel Quinlan is a mathematician at the National University of Ireland at Galway. She received her Ph.D. in algebra from the University of Alberta in 2000 and her current research activities focus on the combination of matrix theory and linear algebra. She likes to fold out symmetrical patterns with paper, and you can search for @rkquinlan on Twitter.
09 How to throw two dice
October 21, 2021 at 8:00 a.m. Beijing time
Description: Gamers such as Monopoly and Catan Roll roll a pair of six-sided dice and use the sum of the results. There are many non-standard dice designs that give the same result distribution. A famous example is the Sitchman dice pair (one of the six sides has a number of points of 1, 2, 2, 3, 3, 4; the other six sides have a number of points of 1, 3, 4, 5, 6, 8), discovered by Colonel George Sichmann and popularized by Martin Gardner, the only pair of heterogeneous dice encoded in positive integers, with the same sum distribution as standard dice. More than six-sided dice, and more than just summation, provide more methods for achieving the desired distribution, some of which were discovered by the reporter.
Speakers: Alexandre Muñiz designed many puzzles and dice.
10 Two Conway geometry games
October 22, 2021 at 0:00 a.m. Beijing time

12 Convex pentagonal dense paving
October 22, 2021 at 8:00 a.m. Beijing time
Description: There is a rich mathematical history of paving planes with convex pentagons, in which Martin Gardner and other participants played a key role. The public can appreciate the related questions and the beautiful patterns generated by the results. The characteristics of all these dense shops are very conducive to mathematical science. For easy hands-on display, the example of a dense paver with integer edges simplifies the creation of a paving pattern. Let me share the mathematical problems involved in determining convex pentagons with integer edges that can be densely paved, referred to here as "pintegons".

"Some people think math sucks, and that really makes me sad – math is more than just arithmetic. Mathematics is everywhere, and it's beautiful, I swear. It's not hard to generalize mathematics. I always see the positive side of math. I always see the bright side of mathematics. Let's go to Portland or San Diego, California, Tacoma, Washington to see how they play games in public, show puzzles, models, and problems to create a positive attitude towards math. This list of places (and people involved) isn't exhaustive, but it inspires me to do more. Maybe it will motivate you as well.

18 Face Changing Polygon: And Martin Gardner follow this winding path
October 24, 2021 at 8:00 a.m. Beijing time
The story begins in 1959 when Martin Gardner introduced me to the face-changing polygon. After discovering another face-changing quadrilateral in 1961, I had the desire to tell the story. Based on a series of face-changing quadrilaterals, I came up with my theory of harmonious face-changing, and I found that they have a one-to-one correspondence with pentaton dominoes, with a small amount of redefinition. Then, I found that the face-changing hexagon is the same, placing the two face-changing models on the same plane, and they have many properties in common. I will show how to make them to confirm my theory. After learning penrose mosaics, I made the most beautiful penrose tile puzzles in 2006, and my desire to show these special guests my penrose mosaic coloring concept. I expect to travel to Atlanta for G4G14, using face-changing polygons as a tool to showcase my Penrose work. I'll bring some of these pieces and other works of art that I'd like to show at my booth. Please visit my website www.r2d3.com for most of this talk, which was written before the invitation was sent.
Introduction: Red Deupree was trained as a scientist. As a child, he aspired to be an inventor or a scientist (guys in white experimental coats). At the age of 30, he came across a computer and was very successful. He made a living writing and maintaining custom software and databases, first for Ford and then for R2D3. After retiring, he wrote applications that normalized the system that colored penrose tiles. When he learned about G4G and had the idea of presenting Penrose's artwork with face-changing quadrilaterals, he wrote an application designing face-changing hexagons. In the case of G4G postponed due to the new crown epidemic, he normalized the theory of harmonious face-changing hexagons, which will be displayed here.
