### Creator of the Archimedes principle

## Archimedes Story

Archimedes was born in the city of Syracuse, Italy in 287 BC. He grew up to be a mathematician, physicist, engineer, inventor, and astronomer. Archimedes is named one of the Greatest mathematicians in history and is one of the greatest scientists in history. His father, Phidias was also a brilliant mathematician and astronomer too. In the 3rd century BC Syracuse had turned into a place known for its math and sciences. Archimedes was curious about all the math and science to learn. He had learned a lot from his teachers and he had become fascinated with math and science. A few years later he traveled to Egypt to study in Alexandria. By the time Archimedes was almost done studying in Alexandria he had earned a reputation and a scholarship. A few years later Archimedes had to determine if King Hiero IIs crown was made of pure gold or weather the goldsmith had put silver into the crown. The hard part of this was he could not damage the crown while finding out it was pure gold or there was silver in it. He discovered how to determine weither it was pure gold or if it had silver while taking a bath. He noticed that when he got into the bath the water started to rise and the water could not compress. He shouted "Eureka!" and got out of the tub and ran into the streets naked. He had realized in the tub that if he divided the mass of the crown by the volume of water he could get the answer to this mystery. He got to the palace and he did the test and he found out that the crown had parts of silver in the crown. to this day he called this "the Archimedes principle".

## Archimedes claw

This is a weapon invented and built by Archimedes. Guards of Syracuse would use this when enemy ships were about to attack Syracuse. The guards would suspend the claw and if it landed in a ship the claw could flip the whole thing over.

## Heat ray

Also a weapon invented and built by Archimedes, this weapon could burn enemy ships by using the suns rays. He would place 3 mirrors one on top, one in the middle, and one on the bottom and the rays would reflect off the mirrors and they would hit of the ship.

## Inventions

## Archimedes screw

Archimedes tries to use as much of his knowledge for his hometown, Syracuse. This invention helps a lot of unfortunate countries like Africa or the Dominican Republic. The Archimedes screw is a screw that goes in the ground and goes deep enough to get to ground water and the ground water makes its way through the drill and comes up to the surface. This invention saves lots of lives every day.

## The Archimedes claw

The Archimedes claw is a weapon that the guards if Syracuse used in the 2nd or 3rd century BC. This weapon can also be called "the ship shaker". The weapon had a crane like arm and had a metal grappling hook on the end of it that suspended (sort of like a fishing rod). You would aim it at an enemy ship and you would try to land the claw in there. If you did there would be a chance that you could flip the whole boat over and possibly sink it. This weapon was great for when wars happened.

## The heat ray

The heat ray is also a weapon invented by Archimedes, its purpose was to burn down enemy ships. He would place mirrors and place one on top, one in the middle, and one on the bottom and the rays would reflect of the mirrors and hit the ship. In the 2nd century BC ships didn't move that fast and if the light stays on something too long it will start to burn and the ship would burn down.

## How has Archimedes work affected the modern world?

Archimedes work has changed the modern world a lot. For example if Archimedes hadn't of discovered the Archimedes principle then we would not be able to deliver cargo on ships or have fun cruises on cruise ships. If he didn't figure out his principle then all boats would sink as soon as someone got on the boat. Also if Archimedes hadn't of invented the Archimedes screw then lots of people in poor countries would die because the only clean water they have there is from the ground. And it would take hours to dig deep enough to get a sip of water (it would also have lots of dirt in it). But with the Archimedes screw it takes less time to get to the ground water and the water comes out clean.
