[ad_1] For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as allowed by the laws of quantum mechanics, an ascending glissando of the frequencies at which the fluid resonates. This research can help us understand some of the most extreme …

[ad_1] Wherever you have fluid, you can also find vortex rings there. Now, scientists have found vortex rings somewhere fascinating – inside a tiny pillar made of a magnetic material, the gadolinium-cobalt intermetallic compound GdCo.2. If you’ve seen smoke rings or bubble rings underwater, you’ve seen vortex rings – donut-shaped …
