November 10, 10-12, Chapel Hill Library “Mathematical Folding” with Dr. Jack Snoeyink.
A triangle is rigid but a rectangle can be squashed into a rhombus.
Structural rigidity explains why by counting degrees of freedom to predict the rigidity or flexibility of networks of fixed-length bars connected by universal joints. We will see that the mathematical study of rigidity can be appreciated at many levels: from the fun of playing with moving shapes, through the satisfaction of proving the carpenters’ ruler theorem, to the puzzlement of conjectures that remain open.
Prof. Jack Snoeyink (Ph.D. Stanford, 1990) works on computational geometry, which is a branch of the theory of computer science that designs and analyzes algorithms and data structures for problems best stated in geometry form. His main application areas are in terrain modeling in geographic information systems, molecular structure validation and improvement in biochemistry, as well as computational topology, computer graphics, and information visualization. He spent 2015-2017 in the swamp, as a program director at the US National Science Foundation, and is glad to be back to his office full of puzzles, and to teaching courses like Algorithms & Analysis and Folding: from paper to proteins.

The Triangle Math Teachers’ Circle is an initiative hosted by the Department of Mathematics at North Carolina State University. It welcomes anybody interested in the teaching profession, at any level, with an interest in learning and practicing the pedagogical approaches of math circles as they pertain to creative problem-solving. This project collaborates with the Chapel Hill Math Circle and is a member organization of the Math Teachers’ Circle Network and the North Carolina Network of Math Teachers’ Circles.
