    LHC well on its way

    A CERN bulletin dated December 14 (that's in the future!) talks about the awesome progress the LHC is making on its way to achieve its planned 3.5 TeV per beam.

    [cdsweb.cern.ch]

    1 eV = 1 electron-volt is the energy that an electron would receive if you were to accelerate it through a potential difference of 1 volt.

    1 TeV = 1 tera eV = 10^12 eV = 1 000 000 000 000 electron-volts.

    To put that energy in perspective, 1 TeV is enough energy to create about 1000 protons at once.

    The LHC is designed to achieve 3.5 TeV per beam, that is, 7.0 TeV when the two proton beams collide.

    So, to grasp what this means, this is like throwing 2 protons against one another with enough energy to produce 7000 more protons.

    (It doesn't actually happen that way, though. The proton-proton collision produces a lot of other stuff, rather than 7000 protons)

    Another way to grasp how awesomely powerful 7 TeV is, consider the fact that *all* chemical reactions (that is, all of chemistry and all of the biochemistry of life) take place at an energy level of a few tens of electron-volts per reaction, that is, about 100 billion times smaller than what the LHC produces in a single collision.

    They are going to get it started up just in time to have it break down again until 2012.

    Where is Swizerland?


    Is it near Autria?

    Well hey, it may lead to the destruction of Earth, but if it means I can have a farcaster-connected dreamhouse with oceanfront views on six star systems, I'm all in favor of it.

    I'm confused. Wasn't Higgs-Boson the butler on Magnum P.I.?

    The Lem piece sounds like a drama-ridden version of Jorge Luis Borges' "The Library of Babel."

    @Sproing:Also, it's hard to imagine two authors whose writing styles are more different than Lem and Borges. >_>

    @ParryLost:Okay, except that both wrote reviews of fictional books. >_> Triple comment, yay!

    @ParryLost: "On some shelf in some hexagon (men reasoned) there must exist a book which is the formula and perfect compendium of all the rest."
