Physicsworld magazine is doing a 'special feature' this month on animal superheroes - those with rather unusual physical abilities.The best of the lot (in my subjective opinion) is the featured-on-the-cover mantis shrimp. Not because of its 'dactyl clu... Read More

Well, the eclipse yesterday was fun. There were enough patches of sky between the clouds to get some good views. I was pleased that the pinhole cameras I made out of miscellaneous cardboard tubes, tins, paper and tinfoil worked really well. Also, the t... Read More

Have a good look at the photo. The pretty rhododendron to the left of the chair looks a bit odd. That's because it's a ghost shrub. No, our garden isn't haunted, and neither have I doctored the photo; it's an example of Pepper's Ghost - an illusi... Read More

The subject of Mars is a popular one. Not only in science fiction but, of course, in real life, too. Curiosity’s presence on the red planet at the moment – you can look at interactive panoramas of Mars! – has… Read more › … Read More

I haven't read ALL of Tolkien's work, but I suspect space-travelling hobbits don't feature anywhere. However, what do feature are hole-dwelling hobbits, and I had the fun of seeing their holes in the countryside near Matamata yesterday. The original se... Read More

In the last couple of weeks, I've been working with one of our technicians tracking down what has been going wrong with one of the experiments we get our third year physics students to do. It's on Brownian Motion. Specifically, analyze the movement of ... Read More

I remember as a student being presented with the proof that the shortest distance between two points is a straight line (at least, on a 2 dimensional flat surface). Although it's almost blatantly obvious, it can be formally proved through Calculus of V... Read More

It's 'Wellness Focus' week here, and there are all kinds of wonderful activities going on to promote health among the employees of the University of Waikato. I've just finished a REV class, which has finished me off for the whole afternoon, I think. Yesterday, I had a free health check - where my blood pressure, cholesterol etc was measured, and … Read More

One consequence of being a physicist is that you can't go anywhere without seeing physics calculations that need doing. I've just been to our library hunting down books on the medical technique of transcranial magnetic stimulation (TMS), which was an interesting exercise in itself, since one textbook I found also has a chapter on homeopathy. Hmm. So how much do … Read More
