Redefining the Kilogram
http://www.azom.com/News.asp?NewsID=13480
Who knew that the kilogram was defined by a piece of platinum-iridium stored in a vault in France? Well, not me. I just took for granted that a kilogram was 1kg on a scale and never thought about the core of the definition. Apparently “Le Grand K” has been losing weight and now scientists are looking for a more constant and accurate way to define the kilogram, such as counting the number of atoms in a silicon crystal (duh). They claim that the kilogram as we know it will remain the same (don’t panic!), it is just the definition that is changing to ensure more accuracy.
