The simple pulley was invented in ancient times by an unknown person. The compound pulley was invented by Archimedes.
Nobody Knows for sure I think Ancient Greece, it was discovered by Archimedes
The pulley was discovered to lift objects that would otherwise be too heavy to lift. Much in the way a crane is used to lift cargo onto ships.
The ancient Greek mathematician Archimedes is credited with discovering the principles of the lever and the pulley. His work on these simple machines laid the foundation for the field of mechanics.
Monasteries are the group that preserved greek writting discovered by crusader.
Archimedes discovered/identified the lever, the pulley, and the screw as simple machines.
While seaborg was in charge of the group, the group discovered the following elements: plutonium (Pu), Americium (Am), curium (Cm), Berkelium (Bk), and Californium (Cf). While those are the elements that the group discovered while Seaborg was the head, in total, the group discovered all of the elements from #94-#103.
