Grad Student Talk: An Infinite Family of Triangles

Abstract: This will be a gentle discussion about my favorite theorem, Poncelet’s Porism. My goal is to provide intuition about the content of this theorem by focusing on a special case involving triangles. I’ll introduce spherical and hyperbolic geometry and discuss an application of the Porism in spaces of constant curvature. I will also explain…Continue Reading Grad Student Talk: An Infinite Family of Triangles

Faculty Talk: The Rationality of Irrationals

 Abstract: When I was in my freshman year at Stony Brook, a friend of mine was perplexed by an interesting question. Suppose we enumerate the rationals on the interval [0,1] in the “standard” way in which the denominators increase: 0, 1, 1/2, 1/3, 2/3, 1/4, 3/4, 1/5, 2/5, 3/5, 4/5, 1/6, 5/6, 1/7, … Suppose…Continue Reading Faculty Talk: The Rationality of Irrationals

Activity: Hexaflexagons

Join us as we have some fun with hexaflexagons, fun little objects you can get by folding pieces of paper. Ajmain Yamin will lead the activity, greatly inspired by Fleron et. al’s book Art & Sculpture and Martin Gardner’s Mathematical Puzzles & Diversions. Materials needed for the activity: Paper (8.5 by 11 in) Scissors Glue stick /…Continue Reading Activity: Hexaflexagons
