The problem with science communication

Yesterday I was part of a very interesting workshop on Science in Society, in Auckland. There was a plethora of good examples of science communication discussed – including forest restoration on the East Coast, biological control of pests in vineyards in Canterbury and improvement of health outcomes for Native Americans in Montana. For me, it […]

Gravitational Waves

The big breaking physics news is the detection of gravitational waves. These waves are distortions in space-time, caused by a large mass doing something spectacular (two colliding black holes in this case)  that propagate across the universe and create tiny changes in space when they reach us. The commentary here describes what goes on. Essentially, […]

Weighing magnetic properties

It's a New Year and there are lots of things to do at work before the students get back in any numbers. There are still summer students and research students here, and in the last couple of days I've been working with a summer student on getting a new piece of equipment running for our […]

Feedback, feedback and more feedback

I've recently received the final report from the Conference Organizing company that looked after the New Zealand Institute of Physics (NZIP) conference, back in July. The report includes such things as the final accounts, the breakdown of who attended, and feedback from participants. It's the feedback that is particularly interesting.  When we attend an event, […]

Plants in circular motion

In our first-year physics lab we have the following horticultural experiment.  Here we have some bulbs growing on a rotating turntable. The array of five pots is placed on the turntable so that the centre pot is at the centre of the turntable; the left- and right-hand pots are at the perimeter.The turntable is rotating […]

A light puzzle

Here's a puzzling photograph that Hans Bachor showed me at the end of the NZ Institute of Physics conference last week. It comes from his public lecture on lasers a week ago. And we don't have the answer to it, so maybe you can enlighten us (pun intended).  The photo is of a demonstration of […]
