With roots in the 17th century, traditional Japanese origami mines beauty from rules, limitations and, ultimately, mathematics. But there’s more to origami than just aesthetic value – scientists, engineers and designers have borrowed from the art form for a wide range of practical purposes. As this short from TED-Ed details, this includes a ‘starshade’ proposed by engineers at NASA’s Jet Propulsion Laboratory, intended to block exoplanet-hunting space telescopes from the glare of distant stars. Featuring appealing and instructive stop-motion visuals from the French animator Charlotte Arene, this short provides a nifty primer on how origami artists are able to fold square pieces of paper into near-infinite forms both beautiful and useful.
