During his lifetime, Archimedes was renowned for his ingenious
mechanical devices, including deadly accurate catapults, compound
pulleys and his famous screw for moving water uphill. He calculated
a nearly precise value for pi, showed how to determine the areas
and volumes of geometric figures, and demonstrated novel ways to
figure out their centers of gravity. His “method of
exhaustion” for determining an area bound by a curve
anticipated integral calculus, the basis of modern science. The
Archimedes screw has been used to reclaim land from the sea in The
Netherlands and is still in use in many countries.
This cache was based on one I did in The Netherlands by Turbohimself.

a cache extraction tool nearby. When you're done with this one
you'll be shouting:
