What is CERN?. CERN. What Happens at CERN?. " In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds." - Albert Einstein.

These are some of the early creators of modern physics, at the 7th Solvay Physics Congress in Brussels, 1933. Even though Max Born said at the time, "Physics as we know it will be over in six months," virtually all of particle physics followed this meeting.

About CERN\'s Name from the Web
The CERN convention states:
The Organization shall provide for collaboration among European States in nuclear research of a pure scientific and fundamental character, and in research essentially related thereto. The Organization shall have no concern with work for military requirements and the results of its experimental and theoretical work shall be published or otherwise made generally available.
A Laboratory for the World
Observers: UNESCO, EU, Israel, Turkey, USA, Japan, Russia
A superconductive disk on the bottom, cooled by liquid nitrogen, causes the magnet above to levitate. The floating magnet induces a current, and therefore a magnetic field, in the superconductor, and the two magnetic fields repel to levitate the magnet.
Hadronic Calorimeter (HCAL)
The brass used for the endcap HCAL comes from recuperated artillery shells from Russian warships
The CMS magnet will be the largest solenoid ever built
The data rate handled by the CMS event builder (~500 Gbit/s) is equivalent to the amount of data currently exchanged by the world\'s Telecom networks
Electromagnetic Calorimeter (ECAL)
The lead tungstate crystals forming the ECAL are 98% metal (by mass) but are completely transparent
"DataGrid" is a project funded by European Union. The objective is to enable next generation scientific exploration which requires intensive computation and analysis of shared large-scale databases, from hundreds of TeraBytes to PetaBytes, across widely distributed scientific communities.
The EU-DataGrid initiative is led by CERN
1990:Tim Berners-Lee, a CERN computer scientist invented the World Wide Web.
The "Web" as it is affectionately called, was originally conceived and developed for the large high-energy physics collaborations which have a demand for instantaneous information sharing between physicists working in different universities and institutes all over the world. Now it has millions of academic and commercial users.
Tim together with Robert Cailliau, another CERN computer scientist, wrote the first WWW client (a browser-editor running under NeXTStep) and the first WWW server along with most of the communications software, defining URLs, HTTP and HTML.
In December 1993 WWW Tim received the IMA award and in 1995 Tim and Robert shared the Association for Computing (ACM) Software System Award for developing the World-Wide Web.
