“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”

Whistle while you work
Computational fluid dynamics was never my forte but I make a mean cup of tea. A
team at the University of Cambridge have addressed an issue that
thwarted acoustic scientists for years, namely how does a kettle whistle?
Apparently the answer lies in pressure pulses that form steam vortices that
produce sound. I wonder Oolong the research took?
