From building transparent potato guns to discussing why scientists are burning astronaut pee (seriously), YouTube channel Smarter Every Day has long been demonstrating the many ways science is ...

A century-old physics question had scientists and mathematicians in knots, until two researchers at the University of Chicago annihilated them. Dustin Kleckner, a postdoctoral scientist, and William ...

GRAND RAPIDS, Mich. — Remember the term polar vortex? We have heard about it and felt that bitter cold arctic air during plenty of West Michigan winters, but what is a vortex and how does it work?? We ...

Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to ...

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 ...

Quantized Vortex Rings in Superfluid Helium Vortex rings analogous to smoke rings in air can be produced in liquid helium. They move in strange ways and exhibit discrete quantum effects on a large ...

A complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...

The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...
