All events will take place on Saturday, January 18 between 9:00 am and 4:00 pm in a variety of locations at the JMM. All events on the Mathemati-Con program are open to the public.

Mathematical Art Exhibition, organized by Robert Fathauer, Tessellations Company, and Nathan Selikoff, Digital Awakening Studios and supported by the Special Interest Group of the MAA for Mathematics and the Arts, and the Bridges Organization. A popular feature at the Joint Mathematics Meetings, this exhibition provides a break in your day. On display are works in various media by artists who are inspired by mathematics and by mathematicians who use visual art to express their love of mathematics. Topology, fractals, polyhedra, and tiling are some of the ideas at play here. Do not miss this unique opportunity for a different perspective on mathematics. The exhibition will be located inside the Joint Mathematics Exhibits and open during the same exhibit hours, but note that exhibits will be open on Saturday, 9:00 am - noon.

Who Wants to Be a Mathematician Championship, organized by Michael A. Breen, American Mathematical Society, and William T. Butterworth, DePaul University; Saturday, 10:00 am - 11:45 am. Show your support for top high school students from the U.S., Canada, and the U.K. in this international Who Wants to Be a Mathematician as they compete for a US\$5,000 first prize for themselves and US\$5,000 for their school’s math department. Come match wits with the contestants, support their mathematical achievement, and have tremendous fun at the same time..

Showtime!: What have mathematicians done for us?, presented by Chris Budd, 2020 JPBM Communications Award Winner, 1:00 – 2:00 pm. Mathematics has played a vital role in the development of human civilisation, and is the foundation of much of modern technology and popular culture. However, the achievements of mathematics and mathematicians are often unknown or misunderstood. The contribution of mathematicians over the centuries will be celebrated, showing how mathematical ideas have huge relevance today – varying between Maxwell and the mobile phone, Florence Nightingale and modern statistics, Pythagoras and the development of music, Euclid and art, Euler and Facebook, and Cayley and Google. Even basic mathematics can make a profound difference to our lives.

Showtime!: A Dozen Proofs That 1=2: A Misguided Review of Mathematics, presented by James Tanton, 2020 JPBM Communications Award Winner; 2:00 - 3:00 pm. Guidobaldo del Monte (1545-1647), a patron and friend of Galileo Galilei, believed he had witnessed the creation of something out of nothing when he established mathematically that zero equals one. He thereby thought that proved the existence of God! Although I daren't be so bold with my claims, I am willing to prove instead that one equals two. And, moreover, just to convince you that I am right I will do so multiple times, drawing upon ideas from algebra and arithmetic, coloring and experiment, physical action and pure thought! Will you find fault with any of my "proofs?"

Julia Robinson Mathematics Festival, organized by Thomas J. Clark, Dordt University, Hector Rosario, Julia Robinson Mathematics Festival, Mark Saul, Julia Robinson Mathematics Festival, and Phil Yasskin, Texas A &M University, 1:00 - 3:00 pm. The Julia Robinson Mathematics Festival (JRMF) is an outreach event with many tables, each consisting of a mathematical game, puzzle, problem set, or activity. Participants (students, teachers, and faculty) will move among the tables, choosing for themselves which activity to engage in and the length of time they spend on the activity. Facilitators will manage the work, guiding and offering hints, but not demonstrating or teaching – creating a space for participants to discover, explore, and enjoy mathematics. The activities are highly interactive, will vary in complexity, and will evolve in structure in response to the choices made by participants. The event will also provide faculty and teachers and opportunity to experience the JRMF for themselves and learn how they might bring it back to their own university, school, or math circle.offer, and on the logistics and dynamics of running an effective circle. The sponsor for this demonstration is SIGMAA MCST.

MAA-AMS-SIAM Gerald and Judith Porter Public Lecture, by Rajiv Maheswaran, Second Spectrum, The Fantastic Intersection of Math and Sports: Where No One is Afraid of a Decimal Point ; Saturday, 3:00 pm.
