The Archimedes Screw

The NY Times has a great story on Archimedes and his achievements.  The screw is perhaps the most important. Engineers recently discovered that if you run the screw backwards, you can create  electricity. According to the Times, "unlike the turbine blades that spin in huge hydro-power plants like the Hoover Dam, an Archimedes screw permits fish to swim through it and emerge at the other end almost unscathed."

The screw is not Archimedes only invention. He solved abstract mathematical problems and engineered devices to take advantage of physics.

This story might be a great addition to those of us who teach Greece and World History.
