Landing gear failure

Last night our cat failed to live up to the reputation of his species for executing four-footed landings when he lept off a perch in hot pursuit of a piece of string, landed on his front paws with too much forward rotation, performed a graceful flick-flack and thuded head first into the CD rack. After […]

What’s happening in Geneva?

In the last few days I’ve had a couple of people ask what is happening with the Large Hadron Collider. Well, if you want the latest news, you can grab the press releases from http://lhc.web.cern.ch/lhc/News.htm . In short, they are doing various tests, and finding and addressing various problems as they arise. It now looks like November […]

Science Fair

For those in easy reach of Hamilton Gardens, the NIWA Science Fair is well worth a visit.

The method […]

Sophie’s law of gravitation

With reference to my entry last week, here is the bit in Jostein Gaarder’s Sophie’s World about gravity. Spot the misconception. Sophie is talking to Alberto: ‘Well, if the moon was drawn to the earth with the same foce that causes the apple to fall, one day the moon would come crashing to earth instead […]

More energy issues

You may have seen the article in the NZ Herald on Saturday about our use of fossil fuels (The Carbon Party’s Over, Chris Barton, NZ Herald 8 August 2009). The bit I loved about this article was translating a barrel of oil (159 litres) into more everyday terms – namely the energy in it is […]
