Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

The aft tail boom of the Bell 429 was discovered 390 feet from the main wreckage. Credit: NTSB Flight training should not result in unrecoverable flight conditions or catastrophic structural failures, ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...
