Scientists at an Ottawa lab are working toward a unique goal — to try to make sure the scales of the future are as accurate as possible. Dr. Barry Wood is a fellow at the National Research Council's ...

The big science-y news of last week was the vote to officially redefine of the kilogram-- see the stories in Physics World and Physics Today for more detail--after decades of work by physicists on ...

Metrology, the branch of science dedicated to measurement, has created better and better systems of measurement for the kilogram based on fundamental principles rather than arbitrary chunks of metal ...

It has been used as a standard unit of weight measurement since the time of the French revolution, based on the precise mass of a lump of metal held in Paris. But the kilogram may be about to be given ...
