Important Inventions

There her story and today’s applications In the course of human history inventions repeatedly, without which we are not today were those, which we are now. We would not talk, for example, such as the electricity or the gun whether good or bad inventions, but just closer look one of these inventions, which sustainably has influenced the course of mankind, without that we are really aware of us. The scale. At the scales, it is a bit like with the invention of the wheel. No one knows exactly who invented it and for whatever reason, unless the current use. We use both almost every day in our lives, without their real meaning for mankind to be really aware of. The first scales over 7000 years old? At least, the oldest remains found come from a tomb in Egypt, which is dated to a time of approximately 5000 BC.

Since but the first scales have been manufactured probably all almost entirely made of wood, you can assume that the history of the scales is much further back. Of course the balances in the course of history evolved always. Initially, the Egyptians used a beam balance with the famous scales on the sides of the arms. Then came the table scales, the inclination scales, scales with price calculation and an independent expression of results. “” “By the way, was” the first name in the German language in the wage Act, with only a “, what 1927 then to scale”, the better to car “due to changed.

Scales are used traditionally in many places in our lives. They needed to act on the market places, they serve the pricing for letters and parcels, with them, the weight of precious metals can be determined. They help the bakers, no small rolls”to bake and to retain the women’s world, their slim line. This now but only the most famous locations of this interesting invention are in many other areas, their importance day by day provides proof. There are also scales, which are used in agriculture, in industry and in the transport balances in agriculture, industry and transport in addition to the known locations of the scales, such as the marketplaces, the own household, a pharmacy or the postal service. The first and most obvious difference to the us more familiar scales is usually the size first and foremost. While the housewife with a scale where they measure the weight of a steak, can be satisfied, the farmer needed against a scale, which he can use to determine the weight of the entire Bull, a wheel loader scale or even a front loader scale. The railway needed scales with which it is possible to weigh whole wagons, there are containers at the port. Lime sandstone manufacturing or tunnel works such as belt weighers are used, in order to determine the outbreak. “Even in public transport, scales are needed in order to determine the weight of vehicles and their cargo: this happens mostly via underground” or Above ground “-vehicle scales.” Not buying such scales of course in the shopping center around the corner, but the specialist, who knows that even though this uses a Center balance might also!
