Quarks Galore - Physics Stop

Marcus Wilson Jun 02, 2010

Here's a nice example of some particle physics from the LHCb experiment at the Large Hadron Collider at CERN.http://lhcb-public.web.cern.ch/lhcb-public/Images_2010/BsDsMuNu.png(taken from the LHCb news page at http://lhcb-public.web.cern.ch/lhcb-public/ )The picture shows an unfortunately-named Bs particle (for Beauty Strange), produced as a result of a 7 TeV proton-proton collision. This particle doesn't live long; it decays into a Ds+ particle, a mu- lepton and a … Read More

Should we be reducing building insulation to improve energy efficiency? - The Science of Architecture

Ken Collins Apr 22, 2010

I recently read an article on the cost of reducing our carbon footprint to pre-1990 levels. It suggested that the actual cost to consumers would be minimal, adding only a few percent to daily consumables. That is except for air travel, which would jump 150%. In effect they tried to debunk the myth that taxing the use … Read More

The power of the ocean - Hot Topic

Bryan Walker Jan 20, 2010

The following column was published in the Waikato Times on 19 January Silent, invisible, predictable, sustainable. Those are the four words Crest Energy uses to describe its planned marine turbine power generation project in the Kaipara Harbour. Capturing the power of the tidal movement of the up to 8,000 million cubic metres of water which pass in [...] … Read More

Friedman: China beating US on low carbon energy - Hot Topic

Bryan Walker Jan 13, 2010

Thomas Friedman is now doubtful that China will follow an American lead towards a greener economy, as he suggested in his book Hot, Flat and Crowded reviewed here. He considers rather that it is more likely to pull ahead of the US. He writes from China in his recent column in the New York Times [...] … Read More

Simple Machines - Physics Stop

Marcus Wilson Dec 26, 2009

There's a lot to do while driving.   Look at the road - watch the speedo (98 kmh - OK there), watch the road - look in mirrors - check fuel gauge (half - OK there) - watch road - watch that car at the intersection ahead - check temperature gauge (where it should be) - eyes on road - glance … Read More

Our Choice: Al’s plan to solve the climate crisis - Hot Topic

Bryan Walker Nov 16, 2009

Al Gore hasn’t been resting on his laurels since An Inconvenient Truth. His substantial new book Our Choice: A Plan to Solve the Climate Crisis has grown out of the more than 30 lengthy and intensive “Solution Summits” he has organised to enable leading experts from round the world to share their knowledge and experience in [...] … Read More

The Electric Car and metrics - Physics Stop

Marcus Wilson Sep 01, 2009

I was reading in the New Zealand Herald at the weekend about a curious problem relating to electric cars. But it's not a technological problem - it's one of language.My car runs on petrol. It's fuel economy is pretty easy to measure. Start with a full tank, take a note of the odometer, run it until the gauge gets … Read More
