Bad light stopped play

One of the top challenges for physics in the modern era, along with Climate Change and explaining Dark Energy, has to be fixing the problem of bad light*. (I’m talking cricket – what else?) It’s a quintessentially English problem. It’s not raining, the pitch is perfectly playable, the spectators (COVID-19 notwithstanding) are enjoying themselves, but […]

BIG idea physics

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 […]

Vortices and the end of Nemo

Well, that was a most unsatisfying end to a novel. After building up to an exciting conclusion, Nemo decides he’s had enough of wreaking revenge on his enemies* and plunges The Nautilus into the Moskenstraumen (Maelstrom) whirlpool off the Lofoten Islands, Norway, where, presumably, there is no return. (Or is there? I note there’s a […]

The bed of nails

It’s always fun to see this demonstrated. Here’s Haggis Henderson, at the recent NZ Institute of Physics conference in Christchurch, not only lying on a bed of nails but having a teenager stand on him too. He survived the experience, though I can’t vouch for what his back looked like afterwards. The bed of nails […]

Jigsaw puzzles

Last night I completed a project that’s been going for the last three months – a 1000 piece jigsaw. This one was pretty but particularly fiendish – being a street map of Paris. There’s not a lot of variation from piece to piece – green background with white streets, with limited clues.  There are river […]

Sycamore seeds and wind turbines

At the recent NZ Institute of Physics conference in Dunedin we heard about a wide range of different physics topics -measuring electrical forces; atomic frequency combs; why a highly gendered physics class is not a good thing and measuring forces with your phone.  One very simple but thought-provoking presentation was by Tim Molteno – on […]
