What was Archimedes most famous invention and discovery

Archimedes:


Archimedes was born in 287 B.C the Sicily island of South-west Italy. Archimedes father was Fediyash who was the famous geographer of his period. Archimedes has completed his study in the famous university of Alexandria of the Egypt Nation. Archimedes gets the Education of Geometrical math from the Euclid Conan. After receiving all the knowledge about mathematics in young age Archimedes went to his birth place Syracuse and starts to do research on math. By the request of the king Hiero II of Syracuse he have make research and invention of scientific machine and devices. King Hero was the good friend of Archimedes so he respect the king request.

Syracuse king Hiero II was a brave warrior and the devotee of God. While celebrating his victories he used to worship any one God. He orders Goldsmith to make some design of gold for the sacrifice to God. He have provided fixed amount of Gold to make a golden Crown.  King was very pleased by the design of Royal Crown. But he also has doubt about the mixing of Silver in the Golden Crown. So king wants to test it without breaking the Crown.  He calls Archimedes and discuss about the current matters. He said that he want to check the mixture of gold in crown without breaking it.

Archimedes was deeply concern by it. He starts to think deeply. He was tired of thinking and he has no idea what to do. One day he was bathing in his tub he feel that the water level rises when he enter the tub. And also he feels lighter inside water. After noticing this all he have some idea in his brain.He thought that the water displace will be equal to the weight of the floating object. He was extremely happy. He jump out of bath tub naked and run over the street of Syracuse shouting Eureka....Eureka.....Eureka (meaning : I found out). Finally he reaches to home naked. In home he was able to perform same experiment in Royal Crown to test the volume of mixture. On the basis of this experiment he discover the famous Law which state that, When the body is fully or partially immerse in water, it experience some force and became lighter which is equal to the water displace by the floating object.

Archimedes put the Crown inside the container filled with water. He measure the mass of the over flooded from the container. After that Archimedes put the pure Gold Crown in container after refilling by water. Archimedes again measure the over flooded water. In comparing the two over flooded water he found the different in there mass. From this experiment Archimedes calculated the exact amount of impurity in the Royal Crown.


This experiment gives birth to the new principle. According to it "Anybody if fully or partially immersed in water it experience an up thrust which is equal to the weight of the displaced water". Nowadays this principle is used to measure the density of an object. Archimedes also formulated the Law of the flotation. Archimedes also formulated the principle of Lever in the Mechanics. Archimedes carries entire ship from the shore to the shipyard by the help of Lever, Pulley and Wheel Axle. People were extremely surprise from this demonstration. People believed that Archimedes have some supernatural power from god so that he was able to lift the ship. Archimedes also claimed that if he gets the sufficient long rod and the place to fix the Lever, then he can lift the entire earth. Archimedes invented the water screw which can lift water up. He has invented many machines which are used in the Warfare. This machines works with the help of Lever and Pulley.

But Archimedes was well known from his invention in mathematics. He have intention to be familiar as the Mathematician. After he wants to keeps the Geometrical instrument in his Cemetery after his death. As per his wish, Roman general keep some Geometrical device along with death body of Archimedes inside the coffin. The death of Archimedes was very big losses. It's the biggest misfortune that happens due to the blindness created by over excitement of the victory. Roman general has invaded the Syracuse but Archimedes was unknown about this. He was busy in solving the problem of Geometry. Roman general have order to protect the Archimedes and his family member. General order his soldier to fetch Archimedes. Soldier reaches to Archimedes and informs Archimedes that general have order him to meet general. Till that time Archimedes was unknown about that his country looses the battle and it is under the enemies capture. Archimedes told him, whose general? Who's order? Wait there I will come soon after finding the solution of these problems? And he turns back and starts solving problems. In that very moment within a one blow that Roman soldier cut down Archimedes head. During that time Archimedes was 75 years old. That's big misfortune for Roman. They invaded the country but loose that great treasury. In his respect Roman soldier make a symbol of Sphere and Cylinder on his cemetery.

Archimedes was world greatest scientist. He has made great contribution on the research of math, physics, mechanics and geography. Some scientist used to believe that there is no greatest then he till Isaac Newton came.
