As we drove on a family outing at the weekend, we sung “Alice the camel”. For those who don’t know it, it goes like this (to the tune of “Dem Bones”): “Alice the camel had five humps; Alice the camel had five humps; Alice the camel had five humps; so go, Alice go! Alice the […]

“Don’t eat beef.” Such a statement does not go down well in New Zealand, especially in Waikato, where the cow reigns supreme. I don’t say it as someone who wants to peddle a “Meat is Murder” message. I don’t believe that at all. I say it as someone who wants New Zealand to take Climate […]

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 […]
Continue readingColour blindness and Bayes’ theorem
Following from my last post, there’s more to say about colour blindness in my family. This time we’ll look at my side of the family. My maternal grandfather was red-green colour blind. That means my mother is a carrier of red-green colour blindness, with a “faulty” (well, “alternative” would be better) X-chromosome. And as a […]

We’ve known for a while that child number 1 (male) is red-green colour blind. This comes as no surprise – with his maternal grandfather being the same. The genes responsible lurk on the X-chromosome. That means mother is a carrier of red-green colour blindness, and child number 1 had a 50:50 chance of picking up […]
Continue readingHydrophobic cabbage
Saturday afternoon saw a break in the rain, and I was able to get out into the garden. The first thing I did was to harvest a red cabbage for dinner. The nice bit of the cabbage is the tightly rolled leaves in the middle, but surrounding that are a whole lot of larger leaves, […]

So, yesterday we had our Science Communication students looking at social media and blogging in particular. Alison Campbell and I talked through what makes a good science blog, and the students got to explore sciblogs.co.nz and look for themselves*. In the coming week, the students need to put up a blog entry themselves. (I’m afraid […]
Continue readingCell phones give you cancer. Yeah, right.
It’s been a couple of weeks since the NIH studies on mice, rats and cellphones hit the headlines. The studies were released with perfect timing to be used in our Science Communication paper – a third-year level paper for science undergraduates on communicating science ideas well. In short, we had half the class look at […]
Continue readingThe difference between an engineer and a physicist
As a researcher who has recently published an article in the elegantly-named journal ‘Biomedical Physics and Engineering Express’ (in other words, biology, medicine, physics, engineering all in one) it’s clear to me that the boundaries that we often like to use to define ourselves are rather blurry. I am a physicist (yes!) but also, at […]
Continue readingStatic hair
It’s one of those annoying laws of nature that the times you want to do a demonstration of static electricity with a Van der Graaf generator are the times when the atmosphere is least suited to it. Damp conditions equals a damp demonstration. But yesterday was really good. No Van der Graaf generator needed – […]
