ooooh, snuck out of the superconducting state. Expensive!

There's energy in that thar beam! :-)

Good physicists are not necessarily good engineers. That is why ITER will never work.

GEO600 might be a counter-example, tho. I've read that because of a very tight budget, much of the hands-on-engineering was actually done by physicists themselves instead of subcontracting it. And it seems to work nevertheless ;-).

... and British (GEO600 is a joint German-British project), but yes, it's located in Germany.

OK. I've read that the Brits have built the first example of Boole's Analytical Engine. Tremble, IBM!

It is always Big Science, whether On or Off.

From LHC@home forum I learned

From LHC@home forum I learned that damage is worse than expected and a two months delay is foreseen. A faulty electrical connector between two magnets melted and provoked havoc. Big currents always are big risks.

Well, I sure know I wouldn't want to go into a tunnel to make repairs until the place had gotten a little warmed up after a liquid helium leak.

That'd even be worse than a Canadian winter!

Actually, I'm surprised it's worked as well as it has so far. These things never run smooth.

Although I was talking with my students yesterday, and they wanted to know about the British equivalent of NASA..so I told them about our Mars Beagle that we sent up there...and how it didn't work.

They concluded that clearly there aren't enough girls working for them. I suspect that is also the problem with the LHC ;)

Physics is for gurls!
