Researchers unfold elegant equations to explain the enigma of expanding origami

Some origami figures expand when stretched, a configuration useful to scientists and engineers. Credit: Robert Felt/Georgia Tech Most materials—from rubber bands to steel beams—thin out as they are stretched, but engineers can use origami’s interlocking ridges and precise folds to reverse this tendency and build devices that grow wider as they are pulled apart.

Engineer uses ancient art of origami to solve a very modern aerospace problem

A starshade can help find exoplanets, but getting one inside a rocket is a challenge. Credit: Manan Arya If you’ve ever made an origami paper crane, using folds and creases to transform a square piece of craft paper into the delicate long-necked bird, it may seem odd that those same folding techniques are being used … Read more
