Rayleigh-Taylor Instabilities in Supernovae Explosions: Density
The following calculation shows the development and evolution of Rayleigh-Taylor instabilities which develop behind the supernova blast wave on a time scale of a few hours. The initial model was chosen to provide a good representation for the progenitor star for Supernova 1987A. The calculation was performed using the Piecewise-Parabolic Method for hydrodynamics on a two-dimensional spherical grid with rotational symmetry about the vertical axis and equatorial symmetry about the horizontal axis.

Erythemal Index for August 2000 through July 2001: Rotating Globe
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the

Christ's at war
A letter written exactly 96 years ago by a young British solider serving in Gallipoli is among an archive of correspondence from men caught up in the First World War that will be on show to the public for the first time during Open Cambridge, when the Bodley Library of Christ's College opens its doors on 9 and 10 September. The letters displayed have been chosen from a total of around 30 sent by old boys of the Perse School in Cambridge to their headmaster WHD Rouse, who was a Fellow of Christ'
The Mathew Brady Bunch: Civil War Newspapers
The Civil War was the first American war thoroughly caught on film. Mathew Brady and his crew of photographers captured many images of this divisive war, ranging from portraits to battle scenes. This site offers 1000 annotated Civil War photographs ranging from portraits to battle scenes. Students become reporters, assigned to sort through photos to find one that will bring the war to life for their readers. They write a newspaper article based on their chosen photograph and publish it on the we

Public Policy Meets Brain Science || Radcliffe Institute
Can neuroscience be harnessed to make public policies more effective and attractive? To influence health outcomes, such as rates of obesity and diabetes? To spur social good, such as better planning for retirement? These questions brought together a varied group of experts for "Public Policy and the Brain," a two-day Exploratory Seminar hosted by the Radcliffe Institute. In a seminar coorganized by Cass Sunstein of Harvard Law School and Tali Sharot of University College London, lawyers and econ
