Q:Who knows who invented the screw?
The spirits were invented more than 2,000 years ago, but less than 500 years for fixing things. The first person who describes the spiral is the Greek scientist Archimedes (about 287 BC - 212 BC) The Archimedes spiral is a huge spiral in a wooden cylinder used to The water is raised from one level to another, and the fields are irrigated. Its true inventor may not be Archimedes himself. Maybe he just described something that already existed. Perhaps it was the ancient Egyptian craftsmen who had designed it to use the irrigation on both sides of the river. Archimedes spiral in the ancient society are used to raise water, no one considered to change it into a fixed piece. Archimedes spirals are widely used for water lifting. For example, the Romans used it to drain the mine. In the Middle Ages, carpenters used wooden nails or metal nails to connect furniture and wooden structures. In the 16th century, nail workers began to produce spiral nails, these nails can be more firmly connected things. It was a small step from this nail to the screw. At the end of the eighteenth century, screws were quite popular as fixed parts, because at that time a cheap production method had been found. Screwdriver (chisel) appeared in London around 1780 years. The carpenter found that screwing the screw with a screwdriver was better than a hammer and could fix something better, especially when a fine screw was encountered.
