Little is known for sure about the
Greek physicist and mathematician, Archimedes. He was born in 287 ВС and he died in 212 ВС. He lived in Syracuse in Sicily. Yet the story of how he (1)______his greatest discovery (2)______known for over 2000 years. The story goes like this.
King Hieron II of Syracuse asked Archimedes to find
out (3)_________a goldsmith had told him the truth or not. The goldsmith (4)_________make a pure gold crown for the king but the king suspected that he had in fact used (5)__________of gold and silver.
Archimedes knew that a
mixture would take up more space than the same weight of
pure gold because silver is less dense than gold. But
how could he possibly measure (6)_____________ of the
crown?
He found the answer when he was getting into his bath and slopped some water over the edge. He realized that anything put
into a tub of water would displace exactly its own volume. All
he needed to do was to compare the level of water in his bath (7)_________ and after he put
(8)__________ in. He was
so excited by this idea that he ran naked through the streets of
Syracuse crying 'Eureka!' (9)__________ means 'I have found it!'
He went home
and did the test. The crown displaced more water than a block
of gold with (10) weight.This
proved that the goldsmith (11)________tried to cheat the
king.
