On 10 December this year the Nobel Foundation will celebrate the 100th anniversary of the award of the first Nobel prizes. As the winners of this year’s physics prize – Eric Cornell, Wolfgang Ketterle and Carl Wieman – gather in Stockholm and Oslo, along with the rest of the 2001 prize winners and numerous laureates […]

Earlier this year a group of some 70 scientists spent an intense week in the foothills of the Rocky Mountains in Colorado reviewing the current understanding of the radiation budget of the atmosphere. The meeting, the latest in the series of Chapman Conferences organized by the American Geophysical Union, focused on the so-called anomalous absorption […]
Over the last 50 years, a number of techniques have been developed to analyse surfaces, near-surface layers and interfaces. Each technique has its own peculiar characteristics, and offers a different view of surface phenomena. Positron-annihilation spectroscopy has unique capabilities for detecting vacancy-like defects, ranging from individual missing atoms to micro-voids. Over the last 20 years, […]
If, in this season of bonfires and fireworks, you find yourself holding a sparkler, you might like to consider the remarkable chemical reaction that is taking place before your eyes. You are actually witnessing a self-propagating high-temperature synthesis reaction – one in which the energy generated by the reaction of magnesium and oxygen to form […]
One of the most challenging problems in modern physics is the application of quantum theory to the universe as a whole. Progress in this area has been plagued by two types of problem: conceptual and technical. The conceptual problems arise from the old difficulties of interpreting quantum theory. The standard interpretations require that the measuring […]

Six years on, all that has changed. Now it is possible to watch the chair of the Nobel physics committee announce the winners live over the Web, and sites like PhysicsWeb – the Web site of Physics World – race to be first with the news. Last month was a particularly busy month for PhysicsWeb: […]
