First thing is that they did not need to test "everything" to get it started. When you have 450 GeV protons in the ring, you dont need 7-8 Tesla magnetic field... So they got it started because they could and decided that they can test the high magnetic field setting later.
Second: The incident happened as they *were* testing it in a break from the low energy collisions schedule.
Third: It was more like 6 tons of helium...

But OK, you've got most of the story right.

Yes. It is used here as a unit of energy that *one* particle carries. Take a look at: http://en.wikipedia.org/wiki/Electron_volt The proton weighs 1GeV. 7TeV (Terra electron volts) which the LHC should run at, means that a poor proton will be so energetic that it will have 7000 times the energy that is it's mass. The higher energy a particle, the higher the magnetic field needs to be to curve it around the 27km ring. If the magnets can not handle the design current than that limits the magnetic field, which in turn limits the energy of the particles that you can accelerate. Incidentally, a 7TeV proton has about the same kinetic energy as a mosquito. But imagine that all the energy is being carried by *one* proton. Now, there are 100 billion protons in a beam bunch and 2000 of these bunches running around the LHC, according to the design and in the end, the total kinetic energy comes close to that of an aircraft carrier going at some reasonable speed, I am told... ps. I am not the AC who posted earlier.

True. But it is the *scale* that matters. ~27km long cryogenic line... has that been done before? For example, many off the shelf cryogenics components were not available before the LHC came along... So much was custom made. And now many components became off the shelf with the R&D money that CERN injected into the industry and so MRI machines and other cryogenics systems are becoming cheaper for those who want to use/study them.

+ - Firefox tops European browser market for 1st time->

Submitted by ruphus13
ruphus13 (890164) writes "The EC took a decidedly harder stance against Microsoft and its anti-competitive practices in the browser wars. Those restrictions seem to have yielded results. Firefox, for the first time, has the largest market share amongst browsers. From the post, "StatCounter is now reporting that Firefox 3.0 is the most popular browser in Europe--for the first time. Number one in Europe? That's a milestone, and a sign of very healthy browser competition in Europe. If the European Commission's recent efforts to force Microsoft to offer more browser choice in Windows succeed, Firefox may well stay number one." It is also interesting to note that Firefox has 100% market share on 1 continent — Antarctica! The article states, "I'm guessing the data comes from one user — and he's using Firefox.""

Microsoft Told to Pay Tax on License Fee 282

MissingRainbow writes "To avoid paying taxes in India, Microsoft wanted a court to believe that it is selling its product and that there are no royalty payments involved. Their own EULA worked against them in this particular case however as it states, "the product is licensed, not sold". The court ruled against them."

+ - MIT Student arrested at Airport for LED Art->

An anonymous reader writes "An MIT student was arrested today at Logan Airport because she "had a computer circuit board and wiring in plain view over a black hooded sweat shirt she was wearing" when talking to a staffer at an information booth. She was visiting the airport to greet an arriving friend. She was wearing the shirt at a Career Fair earlier to stand out, and apparently didn't change before entering the airport. The police believed the object was a bomb and she was surrounded by a group of officers with submachine guns. Didn't the city learn its lesson from the Aqua Teen Hunger Scare?"

Star Simpson, 19, had a computer circuit board and wiring in plain view over a black hooded sweat shirt she was wearing, said State Police Maj. Scott Pare, the commanding officer at the airport. "She said that it was a piece of art and she wanted to stand out on career day," Pare said at a news conference.

+ - Nobel Laureate "disses manned spaceflight"

Submitted by perturbed1
perturbed1 (1086477) writes "Nobel laureate Steven Weinberg "disses manned spaceflight" according this Article, calling the International Space Station(ISS) "an orbital turkey," saying that "no important science has come out of it." Weinberg points to NASA's treatment of its Beyond Einstein program (designed to test the Theory of General Relativity) as an example of the agency's misplaced priorities, commenting that "if we suddenly run into extra expenses in the manned spaceflight program, that will be put on the back burner, just as has been done time and time again by NASA."

Weinberg forgets about the largest scientific payload of the space program designed for the ISS, the Alpha Magnetic Spectrometer (AMS), a particle physics experiment designed to search a dark matter signature in cosmic rays. Another Nobel laurate, Samuel Ting leads AMS which cost about $1.5 billion and has been long waiting for a shuttle flight as discussed in this article."

Australia Cracked US Combat Aircraft Codes 280

Posted by kdawson
from the end-run-around-the-bureaucracy dept.
SpamSlapper writes "Former defense minister Kim Beazley has told how Australia cracked top-secret American combat aircraft codes in the 1980s to enable the shooting down of enemy aircraft. The radar on Australia's US-made Hornets could not identify most potentially hostile aircraft in the region — they were set up for European threats — but despite many requests, the codes were not provided, so 'In the end we spied on them and we extracted the codes ourselves.' The Americans knew what the Australians were doing and were intrigued by the progress they made."

Whenever a system becomes completely defined, some damn fool discovers something which either abolishes the system or expands it beyond recognition.
