Since I last posted on Wednesday, we have seen about zero sign of any flattening in the exponential growth of COVID-19 cases worldwide. I’m not a epidemiologist, or a health professional, or a infectious disease expert. But I do know what an exponential looks like. With cases doubling about every four days world wide, and […]
Continue readingSo, as I sit at home with a very, very slight headache (i.e. not at work when I would otherwise be so), the now familiar figure of Ashley Bloomfield reports eight new confirmed cases of COVID-19 including two in Waikato. A surprise, given that we had just twelve yesterday? No. A worry? Maybe, but no […]

With the numbers of new COVID-19 cases in China diminishing by the day, China now faces a problem. How to get the country back to work, or partly back to work, or more back to work, without taking too many risks with the virus taking off again. The risk can’t be eliminated, except by shutting […]

I’ve had enough of COVID-19 now. No, I haven’t had it (well, not that I’m aware of), what I mean is I’ve had enough of reading misleading headlines, hearing xenophobic attitudes and dealing with outright selfish behaviour. Let me elaborate: Point 1 We know that every outbreak will be accompanied by a kind of tsunami […]
Continue readingWhile 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 […]

Further to my post a couple of weeks ago about BIG idea physics, I think I should add a further one. To do so I’ll use the words of one of my favourite physicists*, Paul Dirac. It seems to be one of the fundamental features of nature that fundamental physical laws are described in terms […]

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 […]

I’m back at work following a nearly three week break over Christmas. We were fortunate to be offered a house to stay in for a week over Christmas, which enabled us to have a holiday in Dunedin and see the extended family reasonably cheaply. But the house came with a catch: a small, old, cuddly, […]
