Last week child number 1 managed to put a hole in a plasterboard (‘gib’) wall. I wasn’t in the room at the time, but I believe it had something to do starting at one end of the house, running down the corridor, through the bedroom doorway, doing a forward flip onto the bed and sliding […]

What is climate science?
In the last few weeks, I’ve been working with some colleagues at the University of Waikato to construct a first-year course introducing Climate Change Science, with a bit of a NZ focus. This would be suitable for students of all backgrounds (not just science students although those would likely be the majority). It’s not that […]
Continue readingMucky rain
While the south of New Zealand has been struggling with too much rain in recent days, here in the north we are so very short of it (though Saturday’s forecast looks promising). Basically, we have had almost none since Christmas. As someone who relies on rain to wash the car, this means my car is […]
Continue readingThe swimming pool paradox
It’s another warm day, but the breeze isn’t helping much, so off I go to the inviting outdoor swimming pool (banner picture) at the other end of campus. It’s an unheated pool (well, there’s no artificial heat source), which means one thing: It’s going to feel cold when I get in*. I should just jump […]
Continue readingIs car washing so bad we need to ban it?
Apparently, some people enjoy washing their cars. Each to his or her own, I suppose. I mean, some people like duck shooting, some people follow Coronation Street, and some people’s idea of a good day out is to sit on a grass bank at Seddon Park and watch cricket all day. (Guess which one I’ll […]
Continue readingVortices and the end of Nemo
Well, that was a most unsatisfying end to a novel. After building up to an exciting conclusion, Nemo decides he’s had enough of wreaking revenge on his enemies* and plunges The Nautilus into the Moskenstraumen (Maelstrom) whirlpool off the Lofoten Islands, Norway, where, presumably, there is no return. (Or is there? I note there’s a […]
Continue readingTwenty thousand leagues under the sea
I’ve been reading Jules Verne’s novel “Twenty thousand leagues under the sea”, considered as one of the very earliest science fiction stories. In brief, Monsieur Aronnax, and a couple of sidekicks, are taken prisoner by Captain Nemo and his mysterious crew and treated to an underwater voyage around the world on the truly expansive submarine, […]
Continue readingMeasuring the temperature
I’ve just bought some thermometers, to use with a first-year physics class. A box of ten of them. Alcohol filled, which makes them a whole lot safer than the mercury ones. (If you have a mercury thermometer, my advice is never, ever break it, especially if it’s at home. I broke one at university a […]
Continue readingWhere will cyclone Oma go?
Cyclone Oma has ground to a halt between Vanuatu and New Caledonia. That’s not to say the cyclone has fizzled out – rather I mean it’s not changing its location very fast. But that’s may be about to change. But where will it go now? I note that there is a large discrepancy between where […]
Continue readingIn praise of fixable appliances
Last week saw the first ‘fault’ on our washing machine. We’ve had this particular one for nine months, and with a baby and young boy in the house it is well used. When I went into the laundry to empty the machine I found the cycle had not finished as I had expected. Instead, the […]
