I worked on the ALICE-LHC experiment for almost 2 years (before getting into graphics..), good luck guys!!

Run, run, run ...
If nothings going to happen why is Gordon Freeman there ?
But I didn't see any crowbars!
That rap is good, but Brian Cox's lecture really explains everything better. Between the two I almost feel like I know what's going on. (I'm now a huuuuge Brian Cox junky, the man has a gift for making the insanely complex easy to understand. )

Ahh, him! I haven;t watched the talk yet but I saw a documentary about this presented by him on BBC4 the other day. I agree he seems like a pretty cool guy.
He was in some band before his career as a physicist. D'ream I think it was, did the silly "things can only get better" tune that New Labour used during their 1997 election campaign.
The biggest and most expensive civilian experiment in the history of science is finally underway.
At 9.28am UK time, the control room at the CERN laboratory erupted into cheers and applause as a pair of dots on a computer screen showed that a beam of particles had successfully completed its first lap of the Large Hadron Collider (LHC), the £3.6 billion “Big Bang machine” that will open a new window on the Universe.
It took less than an hour to guide the stream of particles around its inaugural circuit: the first protons had been fired into the 27km ring at 8.32am.
“Thank you, thank you everyone,” said Lyn Evans, project leader of the LHC, as the beam finished its first lap.
Almost an hour earlier, scientists endured an anxious 48-second wait between the generation of the first pulse of protons, and a tiny flash of light on a screen that showed the beam had made it around the first 3km of the ring.
The LHC team then steered the beam of protons around the entire circuit, stopping it at points along the way to correct their aim. By 8.55am, the beam was half way around, passing through the first four of the atom-smasher’s eight sectors.
“Wow!” Dr Evans exclaimed, as it emerged that the beam had completed its first half-lap just 26 minutes after the insertion process began.
“The beam is now half way around the LHC, and it’s been through two experiments, ALICE and CMS. CMS has seen some beautiful tracks. We’ve now stopped the beam and we’re making some corrections, and then we’ll move around octant by octant. We’ve got four more to do. At the rate we’re going, within an hour we’ll have the beam all around the LHC.”
Beam-stoppers, or absorbing blocks, were being used to prevent the beam from passing too far along the narrow vacuum tube, which has the diameter of a 50p piece, before scientists think they have pointed it correctly. These were being progressively removed, until protons could circulate.
Once the LHC’s clockwise beam had been inserted, scientists moved on to the anti-clockwise beam in the afternoon. Shortly after 2pm, the second stream of particles was also making its way around the collider.
The next challenge is to “capture” both beams, so they fire in neat 2mm pulses, and to fine-tune them. Then the LHC will move on to collide the two, to recreate the conditions of the Big Bang. There will be no collisions today, but it is possible that some trial collisions will be performed as early as next week, to help scientists to calibrate their detectors.
Frankly I can't imagine why anyone would choose to believe a religion based creation story when the scientific alternative is so much more elegant and fastinating. And hell, it still leaves the door wide open for the existance of a God!
