Archimedes was one of the most important
thinkers in world history. This Greek scientist,
who lived about 2,300 years ago, was a
student of science and mathematics, as well
as all forms of learning. Archimedes studied
spirals and circles and the idea of
pi, a fraction
used to find the area and distance around
circles. He was one of the first scientists to
use experimentation to test his ideas. He
worked with simple machines and explored
the uses of the lever. He explained the idea of
the lever by saying, “Give me a place to stand,
and I will move the Earth.”
Archimedes was a close friend of the king of
Sicily. The king asked him to determine if a
gold crown he had ordered was completely
gold or had cheaper metals in it. Archimedes
was taking a bath when he discovered the
answer. He realized that every metal on the
crown displaced a different amount of water.
The amount of water that moved was due to a
metal’s weight. He realized that water could
be used to compare the specific weights of
different metals. Archimedes was so
jubilant
at his discovery that he jumped out of his bath.
He forgot his clothes and ran to the king’s
palace shouting, “Eureka!” which means, “I’ve
found it!”
Archimedes also studied other properties
of water, such as how objects floated. He
developed a tool used to bring water uphill to
dry areas of land. It is called the Archimedes
screw. It was used to irrigate crops. It was
based on his study of a kind of seashell with
a spiral shape. Archimedes helped his king
by designing war machines to fight off their
Roman enemies. He was killed by a Roman
soldier during a siege of his city, but his
memory and discoveries live on.
