- Best Known As: Ancient Greek mathematician who said "Eureka!"
One of the great scientists of antiquity, Archimedes is known for his mathematical work, his theories of mechanics and his clever use of machines in the defense of Syracuse against the Romans. It is believed he studied under followers of Euclid in Alexandria, Egypt before returning to his native Syracuse, then an independent Greek city-state. He proved that an object plunged into liquid becomes lighter by an amount equal to the weight of liquid it displaces; popular tradition has it that Archimedes made the discovery when he stepped into the bathtub, then celebrated by running through the streets shouting "Eureka!" ("I have found it!"). He also worked out the principle of levers, developed a method for expressing large numbers, discovered ways to determine the areas and volumes of solids, calculated an approximation of pi and invented a machine for raising water (called Archimedes' screw). According to legend, Archimedes used a series of machines to keep the Romans at bay for years during the siege of Syracuse. When the Romans finally made it into the city, Archimedes was killed by a soldier.
It's said he filled his bath to the top, and water splashed out when he got in. This was water displacement. He was so excited by his new idea that he ran out into the streets naked (there was no law about this at that time), shouting "Eureka!"("I have got it!").
A machine known as the Archimedean Screw. This consisted of a tube wrapped in a spiral around a center core, and laid on it's side at an angle, with the lower end in the water. When the whole assembly was turned, the tube scoops up water, and brings it to the top.

How did the Archimedes screw help the Eygptians?
Archimedes' Screw was one of the earliest kinds of pump, used by the Egyptians to lift water for irrigation of crops.
What was the purpose of the Archimedes screw?
Its Purpose was to irrigate and lift water From mines and Ship Bilges
How do we use Archimedes' discoveries today?
People all around America still use Archimedes discoveries today. Like The snail screw we use that to raise and move water. Another discovery from Archimedes we use today is pi. We use pi to find the circumference for circles. Everyone should use the "Principles of Archimedes" because we use that to weigh objects.
What did Archimedes invent to defend Syracuse?
Archimedes had several inventions to defend Syracuse, including walls that could shoot arrows. The most famous of these inventions was the Archimedes Claw; a device to lift attacking Roman warships out of the water. No one today has been able to figure out how this device worked.
Where and when was first lift used?
The first known use of a lift was in 236 BC by Greek mathematician Archimedes to transport water. The first modern passenger elevator was developed in the mid-19th century by Elisha Otis, with the first commercial elevator installed in 1857 in New York City's Haughwout Department Store.
What catapults did the Archimedes use?
Archimedes is a person is a person, not a group.
How did Archimedes use a bath to find the volume of a person?
he find that the water was risen where he stared to put the person in.
What did Archimedes discover when he stepped into his bath?
The water overflowed when Archimedes jumped in and he knew that there is a relationship between his weight and the volume of the water
What ancient Greek mathematician organized the defense of Syracuse against Rome?
Archimedes, who designed a machine that could be used to lift the Roman Triremes right out of the water, from within the City's walls.
What is the historical background of the screw machine products industry?
The concept of a screw dates back as far the third century B.C., when the Greek mathematician Archimedes designed a water-powered, screw-driven system to lift water.
What do you use to measure the volume of a stone?
You have to use a measuring cylinder and water.
