World day of metrology

Description

To the question "what is Metrology" answer. Although with specialists of this profession we meet quite often. Especially in recent times, when suddenly there is a need for reconciliation whether the domestic counter, cold or hot water supply and check the steelyard scales or any device yet. And not just any test, but adjust and achieve absolute accuracy.
Once the devices was very little, and the detailed accuracy was optional. Well, for example, in maternity homes measured newborn normal ruler, and any gem literally on eyes.

It was impossible to put up with it and scientists around the world have come to the conclusion that it is necessary to develop common standards. This was devoted to the first Conference of experts held in 1875 in Paris, and dubbed the metric Convention.

Although practically this specialization appeared in antiquity, translated meant "Science of measurements", but his focus has received it only after recognition internationally. As a result, gradually disappeared in Russia different "span" and "elbows", giving way to meters, centimeters, kilometers. The same happened abroad. The main instruments in all countries were the units of the international system ", adopted by the Conference on weights and measures.

The founder of metrology in Russia became chemist d.i. Mendeleyev. Already in the year 1867 Congress of Russian scientists, he called for a metric reform and in Russia. But it was only a trigger, which resulted in the Petersburg Academy of Sciences has established an international organization that ensures uniformity of measurement tools worldwide.

Henceforth, metrology our brother and from nowhere. All devices are available in the home, must go through reconciliation, and those that are sold in the store, including the ammeters, voltmeters, ohmmeter and all that stuff, in addition to the factory, pass a pre-sale inspection.

Well, besides work on metrology jelektropodstancijah, water, oil and gas fields. Wherever there is a need to use the appliance. According to preliminary estimates in the world passes this inspection every second.
