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 ...

Kleckner and William Irvine, assistant professor in physics, report their findings on the creation and dynamics of vortex rings in Nature Physics, published online on March 3. Their work relates to ...

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 ...

A new laser based on a swirling vortex of light has been created by physicists in the US. The “topological-defect laser” could be a useful addition to lab-on-a-chip devices, where it could manipulate ...

The same physics that gives tornadoes their ferocious stability lies at the heart of new research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors and ...

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 ...

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, ...
