Coral reefs can be crocheted. The atmosphere can be knit. And a stop sign can be folded into a pair of pants. Welcome to the intersection of math and handicraft. Unexpectedly, handicraft in general, and yarn work in particular, has started to help provide answers to a wide range of mathematical problems. From the way the atmosphere generates weather to the shape of the human brain, knit and crocheted models have provided new insight into the geometry of the natural world....

Trigonometry, from the Greek trigonon, meaning triangle, and metron, meaning measure, is a branch of mathematics that studies the relationships involving lengths and angles of triangles. The field came about during the 3rd century BC from applications of geometry to astronomical studies. The 3rd century astronomers first noted that the lengths of the sides of a right triangle and the angles between those sides have fixed relationships: that is, if at least the length of one of those sides...
