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, ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

Turbulent ball: William Irvine, Takumi Matsuzawa and colleagues have used this apparatus to track turbulence with lasers and high-speed cameras. (Courtesy: Takumi Matsuzawa) Researchers in the US have ...

Physicists have succeeding 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, but creating them ...

Topological defects in ferroic materials are attracting much attention both as a playground of unique physical phenomena and for potential applications in reconfigurable electronic devices. Here, we ...

Here you see the good folks on QI shooting smoke rings across the room. Why does a donut-shaped cloud come out of a circular opening? Why are smokers able to blow smoke rings, even when they’re not ...

Video: Thousands of computer processors working together are needed to produce these detailed simulations of turbulent vortices. State-of-the-art computer graphic systems developed for movies and ...

The physics association from the department of physics, Panjab University, in association with IAPT (Indian Association of Physics Teachers) organized its annual academic meet "Vortex 2013" on Tuesday ...
