It is pointed out in the passage that Archimedes' inventions ----.

In antiquity, prior to the third century B.C., physics
had been a branch of philosophy. It was made a
separate, experimental science by Archimedes of
Syracuse, who lived between 287 and 212 B.C.. He
not only discovered the law of floating objects, or
specific gravity, but also formulated with scientific
exactness the principles of the lever, the pulley, and
the screw. Among his memorable inventions were the
compound pulley and the screw propeller for ships.
Although he has been considered the greatest
technical genius of antiquity, in fact he preferred to
devote himself to pure scientific research. Tradition
relates that he discovered “Archimedes' principle,”
that is, specific gravity, while pondering possible
theories in his bath; when he reached his stunning
insight, he dashed out naked into the street crying
“Eureka!” (“I have found it!”).
