Under pressure

I got some new taps for my kitchen yesterday. The boring technical specitications on that bit of paper marked ‘important – please read’ said ‘do not exceed a pressure of 800 kpa’.  Now, leaving aside the fact that it should be ‘kPa’ not ‘kpa’, that means 800 kilopascals. A pascal is the pressure caused by 1 […]

For those unfamiliar with the Skyline complex, the idea is you sit on a small cart and freewheel down a concrete path, negotiating the various bends inconveniently sited to slow your speed. Great fun, and lots of physics.
