When it comes to mathematics, paper isn't just for pen and pencil any more! Origami, the art and science of paper folding, can be used to explain concepts and solve problems in mathematics-and not just in the field of geometry. The origami activities collected here also relate to topics in calculus, abstract algebra, discrete mathematics, topology, and more. Using origami, learn about: - Solving Cubic Equations - Bucky Balls and PHiZZ units - Matrix models for folds - Gaussian Curvature and much more! These activities, which can enhance the classroom experience, also make great independent student projects and are perfect for math clubs or math circles. To provide readers of Project Origami with as much flexibility as possible, we have made all of the handouts in the book available online.
