Beginning in the late 1990s, origami artists began bringing sophisticated mathematical tools to bear on the problem of origami design, resulting in remarkable advances in both art and in the technological applications of origami. In this talk, Lang discusses some of his own origami mathematical algorithms with examples in artistic, geometric, and technological origami, including the engineering-applicable subfield of rigidly foldable origami—origami made from rigid panels and hinges.

Robert J. Lang is a physicist and a leading theorist of the mathematics of origami. See: langorigami.com.
