...while you're up there? No one's asked and therefore I've never said, but there is one kind of fun thing that I'm hoping I get a chance to do. When my father was on SkyLab, it had a big central chamber with this ring of lockers all the way around the perimeter; it was just big enough that you could run around and create enough centrifugal force to hold you against the lockers and have a little circular jogging track like in 2001: A Space Odyssey. I'm hoping to find a cross-section that...
When it is fully operational, the $6 billion LHC will send beams of protons careening around a 17-mile underground ring, crash them into one another to re-create the immediate aftereffects of the Big Bang, and then monitor the debris in the hopes of learning more about the origins and workings of the universe...
Gillies says last week's functional hiccup was not surprising. A massive machine designed to study miniscule particles will inevitably face problems. The LHC's intricacy is indeed breathtaking: One of the particle detectors on the 17-mile ring (there are four) is connected to enough cable and wiring to wrap around the earth nearly seven times. Scientists had to take into account the gravitational pull of the tides when constructing...
...amount" of helium into the tunnel but that CERN's safety protocols ensured there was no risk to staff. Scientists are not allowed into the tunnel when the machine is running, he says, and first responders after the fault all wore respiratory equipment. All scientists working in the underground ring also carry portable respirators, which they are instructed to use within seconds of a helium leak...
...something to enjoy. Fraught with insecurity, we are left to wonder: Is there something wrong with our cards? Or are we just using them wrong? The downright impotence of these new cards has proven highly frustrating. Perhaps if we could pierce a hole in the card for a keychain ring, easy access would mitigate the problems with sensitivity. But alas, the College will not let us. Surely, no one wants loose readers that work at too long a range, else concerns over security and safety may dominate. But in its attempts to provide protection, the University need not tighten...
