Description: Mathematician Chris Rorres of Drexel University in Philadelphia has taken a close look at Vitruvius's specifications for constructing an Archimedes screw... Recent years have seen a revival of interest in the Archimedes screw, particularly for its proven, trouble-free design and its ability to lift debris-laden water effectively, Rorres remarks. "It has also proved valuable in installations where damage to aquatic life must be minimized."
