The latest issue of Science News profiles the work of several mathematicians who crochet and knit incredibly strange surfaces to illustrate certain complicated mathematical principles. For example, two researchers from the University Bristol used their computer algorithm as crochet instructions to create a Lorenz manifold, a shape that emerges from chaotic systems such as weather. Other crafty scientists crocheted Möbius strips, Klein bottles, and hyperbolic planes (seen here). From the article:
Mathematics has long been an essential tool for the fiber arts. Knitters and crocheters use mathematical principles–often without recognizing them as such–to map the pattern of a cable sweater, for instance, or figure out how to space the stitches when adding a sleeve onto a jacket.
Now, the two crafts are returning the favor. In recent years, mathematicians such as Osinga have started knitting and crocheting concrete physical models of hard-to-visualize mathematical objects. One mathematician's crocheted models of a counterintuitive shape called a hyperbolic plane are enabling her students and fellow mathematicians to gain new insight into startling properties. Other mathematicians have knitted or crocheted fractal objects, surfaces that have no inside or outside, and shapes whose patterns display mathematical theorems.
"Knitting and crocheting are helping us think about math we already know in a different light," says Carolyn Yackel, a mathematician at Mercer University in Macon, Ga.

Graham Clark, the 17-year-old Florida boy accused of pulling off the big Twitter hack, pled not guilty to charges on Tuesday. During the security breach, top accounts including Democratic presidential candidate Joe Biden and Tesla/SpaceX CEO Elon Musk were taken over to push a bitcoin scam.
In this footage, a supercomputer’s CPU cores — nearly 900 of them — are neatly lined up in the Task Manager. The Doom logo appears, generated by code that targets each core. Then Doom itself plays, each “pixel” generated by thrashing a core with just the right amount of busy work. Max Holt: Finally got […]
The UK government today ordered domestic companies to stop buying equipment from Chinese vendor Huawei and to stop using its kit entirely by 2027. Huawei is suspected to be an arm of the Chinese government, breaking into western markets (and maybe its networks) by selling impossibly cheap equipment. The UK only recently approved more Huawei […]
