Swirling rings of fluid have for the first time been tied in a knot. Physicists accomplished the feat with the help of some unlikely lab tools: YouTube videos of dolphins and a 3-D printer. “It’s a ...

The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids that make LCD screens shine? They exist, and in a new Nature Physics study, ...

(Phys.org) —Physicists William Irvine and Dustin Kleckner of the University of Chicago, have for the first time, created a knotted vortex in a fluid. They describe how they printed 3D airfoils and ...

University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, ...

Knotted vortex Two US researchers have effectively created "smoke rings" in water and knotted them together for the first time. The development, reported today in Nature Physics, opens the path to new ...

Researchers formed stable vortex knots in chiral nematic liquid crystals and used electric pulses to reversibly fuse and split them into different knotted forms. (Nanowerk News) The knots in your ...
