Mathematicians call the shape of a doughnut a 'toroid'. Physicists call a swirling fluid a 'vortex'. A toroidal vortex, then, is a swirling doughnut of fluid. This video from the Sleek Geeks archive ...

An artistic pressions of a vortex-ring street analogue to the structure of magnetic field of a NDSTP, where the right- and left- handed vortex rings were highlighted by blue and red, respectively. The ...

On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...
