Experts Suggest Replacing Definition of Kilogram

fenimor writes "The kilogram is the only one of the seven basic units of the international measurement system defined by a physical artifact rather than a natural phenomenon. International team of scientists suggest replacing the kilogram artifact -- a cylinder of platinum-iridium alloy about the size of a plum --with a definition based on one of two unchanging natural phenomena, either a quantity of light or the mass of a fixed number of atoms. They propose to adopt either one of two definitions for the kilogram by selecting a specific value for either the Planck constant or the Avogadro number."

Interest without knowledge?

So this is what happens when you have a group of people with such interest in science but little knowledge? When asked to explain why Spears married and divorced that guy so quick, nobody here knows--yet nobody would comment? Yet when asked to explain why we need a new kilogram standard, we get lots of crap and jokes. Just pick up watching sports.
