For the first time, physicists have recorded sound waves moving through a perfect fluid with the lowest possible viscosity, as permitted by the laws of quantum mechanics, an ascending glissando of the ...

Physicists have observed sound waves moving through a 'perfect' fluid. The results should help scientists study the viscosity in neutron stars, the plasma of the early universe, and other strongly ...

Scientists at MIT have announced that they have recorded the sound of a "perfect fluid." The sound is important because what a so-called "perfect flow" sounds like could help researchers study the ...

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring ...
