Phrase of the day: Rotational superradiance
'Water waves can gain energy when they scatter from a whirlpool-like vortex. That is the conclusion of physicists in Brazil, Canada and the UK, who are the first to observe a phenomenon called "rotational superradiant scattering". The team says that the effect could be used to study black-hole physics.'
