ScienceTabletop water vortex reportedly gives first direct look at a Kelvin-wave turbulence cascade
A science post describes Kelvin waves as tiny helical ripples along superfluid vortices—predicted for decades but difficult to observe.
TLDR
A science post says a classical water vortex on a tabletop provided the first direct look at a Kelvin-wave turbulence cascade. It describes the experiment as a larger-scale counterpart to the hard-to-see ripples along quantized vortices in superfluids, following the same mathematics.
