Surgery with Femtosecond Lasers

An anonymous reader writes "Science Daily has an article on femtosecond lasers, which emit pulses of light that are a billion times shorter than an electronic camera flash and how they are currently being used in LASIK procedures."

  1. Why would anyone want to do this? by jonm · · Score: 2, Funny

    I write in pure HTML - why would anyone want to do otherwise? Oh hang on - wrong thread!

    not really, more like a few milliseconds

    I guess we should really come up with some standard system for measurement in news articles, the JI (Journalist Idiots) System of measurement.

    Time - camera flashs
    Small physical size - human hairs
    Large information - Library of congresses
    Meteor size - VW Bugs

    Any more?

    Height: Empire state buildings. eg. if you stacked a quadrillion pennies they would be X times the height of the Empire State building.

    Height 2: Earth-Moon. eg. if you stacked a quadrillion cases of beer, they would reach X% of the way from the Earth to the Moon.

    Accuracy: Amazing Hole in One. eg. NASA's space probe reached Saturn only 4 microseconds late. That's like sinking a Hole in One from X billion miles.

    Length: Earth circumferences. eg. If you laid all the fiber in the world end-to-end it would stretch around the globe X dozen times.

    Volume: Olympic Swimming Pools. eg. a million cases of beer would fill X Olympic Swimming Pools.

    Then, there's the famous nanoseconds that Grace Hopper used to pass out. They were little pieces of wire an inch(?) long that represented the distance light travels in 1 nanosecond.

    They would get a lot more done if they left the laser on longer.

    Burner speed: older burners. "This fast burner is the equivalent of 40 burners!" Used mainly by the RIAA.
