Archimedean screw
This screw takes its name from Archimedes (c.287-212 BC), a scientist and engineer from Syracuse, Sicily. Archimedean screws were originally used to move water from a low level to a higher level. The screw appears similar to a large corkscrew encased within a hollow pipe. Centuries later, Leonardo da Vinci worked on improving the Archimedean screw in hopes of using the screw design to create devices that had continual motion. His concept suggested pouring water in the top of the screw to force it to constantly turn, which would ultimately help with the running of machinery and the lifting of heavy items. Sadly, in 1500, he stopped his experiments with the Archimedean Screw, feeling that his concepts were unachievable. Today, screws just like Leonardo’s are used for such tasks as reclaiming waterlogged land in the Netherlands and helping to stabilize the Leaning Tower of Pisa.
