Work of national physical laboratories

Throughout history, people have always realized the need for standard weights and measures, and from time to time these standards have been revised, improved, and established by law.
In most big countries of the world there are laboratories, supported largely by government funds, i¥ which scientists are at work on problems of industrial and national i~Torrance~ In England we have the National Physical Laboratory at Eddington. These institutions are also responsible for maintaining and improving the standard s of all the important physical quantities. Scientists from the various countries compare their results and regularly meet for discussion, and often they are able to announce new definitions of the basic units.
