Perfect Silicon Sphere to Redefine the Kilogram

MrCreosote writes "The Age reports optical specialists at CSIRO are helping create a new standard for the kilogram, based on a precise number of atoms in a perfect sphere of silicon. This will replace the International Prototype, a lump of metal alloy in a vault in Paris."

  1. The real reason they are changing it by antifoidulus · · Score: 3, Funny

    is because they are embarrassed of the fact that a T-rex managed to steal the original one and now they need a replacement.

    ..but how can they make sure the new kilogram weighs a kilogram? :)

    A perfect sphere, down to the atom, of 1 kg silicon would require pi to what precision?

    Reminds me of a story - a friend had gotten a boob-job and we were all out for dinner one night. Another common friend of ours hadn't known this and the first time he saw her, he burst out - "You've grown three dimensionally!"

    Weird. I read about this in an exam I took last week. It stated that the present standard kilogram is a mass of platinum and iridium kept at STP underground, and asked what factors might affect the mass of the standard kilogram when it is measured. I answered if any isotopes of platinum or iridium decay, or if the standard kilogram had a velocity close to the speed of light.

    Duck Measurer: "I put a duck on one side of the scale, and use weights (lumps of known mass) on the other side to determine the mass of the duck."
    Some Guy: "Umm, but you already know the mass of the weights, why are you bothering?"
    To see if they float, of course.
