Despite knit fabrics being ubiquitous—and even something you’re likely wearing—the fundamental mechanics of how they form shapes remain largely unexplained. This informative and entertaining (if you enjoy nerdy stuff) video explores the question, “Why does knitting work the way it does?” And how can modern physics decode this “simple” craft? It acts as a gateway to a richer exploration of knitting’s geometry, offering both knitters and scientists a new lens through which to understand—and ultimately engineer—the fabric around us.

From the history of knitting to explanations of basic knit and purl stitches, this video also covers how scientists are using these simple techniques to create futuristic, innovative knits.
