On 19 May the DESY laboratory brought the DESY, including Argonne National Laboratory, celebrations for its 50th-anniversary year to the Budker Institute of Nuclear Physics, a close with a major event in Hamburg, which Jefferson Laboratory and the Laboratoire de saw an impressive 2500 guests in attendance l’Accélérateur Linéaire to name but a few. from all around the world. The celebrations featured various The guest list read like the crème de la speeches, a round-table discussion and crème of particle physics and photon science, different tours of DESY, as well as a banquet, including current and former directors of stage shows and a much acclaimed fellow laboratories, such as CERN, KEK and band.

E x h i b i t i o n CERN shows particle physics in a new light

"Universe of particles" – CERN’s new permanent exhibition in the Globe of Science and Technology – provides a hi-tech experience to intrigue the general public about some of the world’s most sophisticated physics tools and experiments. Among the first attractions to catch the eye are large projections that fill the walls and a 6 m diameter circular screen in the middle of the ground that swirls with stars, planets and particle collisions from the LHC experiments. Visitors are invited to explore spherical, interactive consoles spread around the exhibit focusing on four main Inauguration of the exhibition, left to right: Shirin Brückner, from Atelier Brückner, Dante Martinelli, themes: Why does CERN collide particles?; Swiss Ambassador at the office of the UN and other international organizations, Bruno Meier, How do we accelerate particles?; How do we director-general of Rolex, Rolf Heuer, director-general of CERN, and Charles Beer, Conseiller d'Etat de la detect particles?; and The diversity of CERN.

Exploring and Visualizing Data with IDL JOIN US FOR THIS FREE WEBINAR Wednesday 21 July 2010 2.00 p.m. BST (3.00 p.m. Central Europe, 9.00 a.m. East Coast US)

IDL is used by scientists and engineers worldwide as a platform for data exploration, analysis and visualization. IDL combines the power of a modern programming language with easy-to-use, scriptable tools for working with data. IDL 8.0 includes new features and language enhancements that make exploring and visualizing data even easier and more intuitive. Join us for this webinar to learn some of the basics of using IDL. Topics covered in this session include:
