2. CERN: where antimatter is made
CERN is about fundamental scientific challenges in Particle Physics
Front page, September 19, 2002 More Sci- Than Fi, Physicists Create Antimatter
Physicists working in Europe announced yesterday that they had passed through nature's looking glass and had created atoms made of antimatter, or antiatoms, opening up the possibility of experiments in a realm once reserved for science fiction writers. Such experiments, theorists say, could test some of the basic tenets of modern physics and light the way to a deeper understanding of nature [...] The new
research was conducted by physicists at CERN, the particle physics laboratory outside Geneva.

3. CERN: where the web was born
Fundamental scientific challenges produce disruptive technologies

9. CERN's Users and Collaborating Institutes
another problem?
or a solution? –
uniting the computing resources of particle physics
Europe: institutes, 4603 users Elsewhere: 208 institutes, 1632 users

10. LCG: The LHC Computing Grid Project
a geographically distributed computing facility
for a very large user population of independently-minded scientists
with independent ownership/management of the different nodes
each with different access and usage policies
and serving multiple user communities
