Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered. Vortex beams, rotating like ...

An Australian-led study has provided new insight into the behaviour of rotating superfluids. A defining feature of superfluids is that they exhibit quantised vortices – they can only rotate with one, ...

Liutex is a new physical quantity discovered by Chaoqun Liu et al at University of Texas at Arlington (UTA) in 2018 to describe fluid rotation, which is same important as velocity, pressure, ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. This image is seen as a motion or spiral optical illusion (specifically a ...

French researchers develop sophisticated mathematical model to study the behavior of earthly vortices, like hurricanes and ocean currents What do smoke rings, tornadoes and the Great Red Spot of ...

A new animation using data from ESA’s Venus Express spacecraft shows that the double eye of the giant vortex at Venus’s South pole has disappeared. Results of a study that shows the complex, variable ...

If you were in a spacecraft passing over the Earth’s South Pole, you are likely to see a “polar vortex” — a huge swirling mass of clouds and winds in the upper atmosphere right above the pole, driven ...
