Extreme heat warning: what the first-ever UK Met Office alert means - The Changing Climate

Guest Author Jul 22, 2021

Chloe Brimicombe, University of Reading Summer 2021 will mark a turning point in how heat is seen by the public and communicated by experts. For the first time in its 167-year history, the UK’s Met Office has issued an amber warning for extreme heat for much of Wales and parts of southern, central and western England, where temperatures are … Read More

The swimming pool paradox - Physics Stop

Marcus Wilson Jan 24, 2020

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 in and get on with … Read More

A lot of huffing and puffing - Physics Stop

Marcus Wilson Apr 15, 2015

While there is some great fiction out there, one really shouldn't try to learn much physics from it. One case in point, which I am forced to listen to over and over by the youngest member of our house, is the story of the Three Little Pigs.  I'm not talking here about the relative merits of various building … Read More

A load of rubbish - Physics Stop

Marcus Wilson Feb 19, 2014

I've been reading through a student's report of his summer work placement. He  had a project on improving the performance of a heat exchanger used for getting rid of heat from a cryogenic cooler. The basic concept is that materials are being cooled to about 40 kelvin (that's 40 degrees above absolute zero, minus 233 degrees celsius, by removing … Read More

Thermodynamics of learning - Physics Stop

Marcus Wilson Nov 27, 2013

Last week I attended a conference on Emergent Learning and Threshold Concepts, here at the University of Waikato. It was a very interesting couple of days. As far as academic conferences go, it was unusual in that it was really cross-disciplinary. We had engineers mixing with physiotherapists, and management consultants with dancers. It certainly was interesting to … Read More
