Mapping the spread of Influenza Type A H1N1

There are a number of maps now available on the web that are illustrating in this age of rapid international air travel how fast diseases can travel between countries and around the world:
At a national level the following web sites cover just the United States:
In New Zealand official information on the current outbreak is available from the Ministry of Health.

Countdown to startup of the Large Hadron Collider at CERN

The Large Hadron Collider (LHC), a 27 kilometer-long particle accelerator straddling the border of Switzerland and France just outside Geneva, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN) is preparing for its first small tests in early August, leading to a planned full-track test in September, and the first planned particle collisions before the end of the year. The final step before starting is the chilling of the entire collider to -271.25 C.

On 30 June 2008 The Guardian published a number of articles about the LHC and what it is hoped to discover. (See previous post.)

On 2 July 2008 Scientific American carried an article about what five physics Nobel prize winners thought about the LHC.

On 31 July 2008 The Economist ran an article, noting the LHC's US$10 billion cost.

On 1 August 2008 The Boston Globe had a story with a magnificent set of 27 photographs from CERN of the equipment that makes up the LHC.

By way of comparison, the London Underground's Circle line is 22.5 kilometers long.

Setback for CERN as Fermilab maths mistake causes explosion

In an 8 April 2007 article the Sunday Times reports on a small explosion on 27 March at CERN in Geneva that has possibly set back by months the multi-billion euro Large Hadron Collider (LHC) project to build an experiment to search for evidence of the Higgs Boson. The cause of the explosion was reportedly a miscalculation by staff at CERN's US rival, Fermilab. Official statements have been made by CERN and Fermilab.

I have been out to the visitor centre, Microcosm, at CERN. It is well worth a look. Ever since studying physics at high school I have retained a fascination for the subject reading popular accounts but thought that my maths skills were not up to taking the subject any further. Maybe they were!

In addition, understanding basic physics is very important for anyone involved in flying.
