On Christmas Eve, child number 1 spotted a crack in a window. It’s a double-glazed window, and inspection showed that the small, horizontal crack was in the outermost pane. It was perpendicular to the frame, about three-quarters of the way up one side. The origins are a mystery. It MIGHT have something to do with […]

Repairing a hole in the wall with the diffusion equation
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 […]

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 […]

Yesterday we arrived back in Cambridge after a few days holiday in Auckland, being tourists. We sampled such delights as the unheated hotel swimming pool, the complicated and expensive process of getting on a bus (basically having to find somewhere from which to buy a HOP card, for a non-refundable $10 a card), the completely […]

It’s a beautiful autumn afternoon, we need to get out of the house, and so our bubble sets off on a bike ride around our local neighbourhood, Cambridge Park. The bikes come out of the garage, and, being really certain we have a front door key, close the garage door again. And off we go. […]

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 […]

This morning I’ve been having a quick look through some documentation from The Ministry of Education on proposed changes to NCEA Level 1 Science. For those not familiar with the NZ secondary education system, a typical student would complete NCEA level 1 at the end of year 11. In this regard, it’s broadly similiar to […]
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, […]

Just in case you don’t have a seven-year old boy in your house (in which case this will be obvious) a well-known brand of breakfast cereal here in NZ is currently coming with All-Blacks stats cards. Perfect for finding out your favourite rugby player’s height, number of caps, and how much they can eat for […]

Hello everyone. It’s been a long while since I was blogging, but I am back again now. The second-half of the year is rather less hectic for me, so I have some time to get back to this. I’ve been considering recently the learning that students have achieved in our first year paper “Physics in […]
