Angels and Demons - the movie

An exciting movie but not so accurate from a physics point of view. See here for a discussion. The part played by antimatter is especially misleading.

Climate change - not good news

The latest predictions show that temperatures rises may be about twice as much as predicted a few years ago.
"The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth’s climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago — and could be even worse than that."

"The new projections, published this month in the American Meteorological Society’s Journal of Climate, indicate a median probability of surface warming of 5.2 degrees Celsius by 2100, with a 90% probability range of 3.5 to 7.4 degrees. This can be compared to a median projected increase in the 2003 study of just 2.4 degrees. The difference is caused by several factors rather than any single big change." Climate Change Blog
