Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

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?
