Archimedes contributions to mathematics were also notable, and included solutions to a variety of problems. He worked with mathematics limits and series in a manner that is similar to calculus, and in a treatise on 'counting grains of sand', he made innovative use of the manner of calculating very large numbers before the decimal system was established. Some of Archimedes inventions were just as noteworthy as his scientific achievements.
The Archimedes Screw was a devices for lifting water. The Archimedes Claw was a war weapon used to overturn boats that approached the walls of Syracuse during the siege, and he is also credited with improving various other machines of war, including catapults and mirrored 'heat-rays'.
He was killed during the siege of Syracuse in spite of the orders of the Roman commander that he be spared and treated courteously. Studied for some time in Alexandria. Shaw Image Links Well, what do you think of it? According to Plutarch Archimedes's catapults machines that could hurl objects such as heavy stones forced back the Roman forces on land.
Later writers claimed that Archimedes also set the Roman ships on fire by focusing an arrangement of mirrors on them.
Nevertheless, despite Archimedes's efforts, Syracuse eventually surrendered to the Romans. Archimedes was killed after the city was taken, although it is not known exactly how this occurred. Perhaps while in Egypt, Archimedes invented the water screw, a machine for raising water to bring it to fields.
Another invention was a miniature planetarium, a sphere whose motion imitated that of the earth, sun, moon, and the five planets that were then known to exist.
Euclid's book Elements had included practically all the results of Greek geometry up to Archimedes's time. But Archimedes continued Euclid's work more than anyone before him. One way he did this was to extend what is known as the "method of exhaustion.
Archimedes's investigation of the method of exhaustion helped lead to the current form of mathematics called integral calculus. Although his method is now outdated, the advances that finally outdated it did not occur until about two thousand years after Archimedes lived. Archimedes also came closer than anyone had before him to determining the value of pi, or the number that gives the ratio relation of a circle's circumference its boundary line to its diameter the length of a line passing through its center.
In addition, in his work The Sand Reckoner, he created a new way to show very large numbers. Before this, numbers had been represented by letters of the alphabet, a method that had been very limited.

One such story recounts how a perplexed King Hiero was unable to empty rainwater from the hull of one of his ships.
The King called upon Archimedes for assistance. Archimedes' solution was to create a machine consisting of a hollow tube containing a spiral that could be turned by a handle at one end. When the lower end of the tube was placed into the hull and the handle turned, water was carried up the tube and out of the boat. The Archimedes Screw is still used as a method of irrigation in developing countries.
King Hiero had commissioned a new royal crown for which he provided solid gold to the goldsmith. When the crown arrived, King Hiero was suspicious that the goldsmith only used some of the gold, kept the rest for himself and added silver to make the crown the correct weight.
Archimedes was asked to determine whether or not the crown was pure gold without harming it in the process. Archimedes was perplexed but found inspiration while taking a bath. He noticed that the full bath overflowed when he lowered himself into it, and suddenly realized that he could measure the crown's volume by the amount of water it displaced. He knew that since he could measure the crown's volume, all he had to do was discover its weight in order to calculate its density and hence its purity.
During Archimedes' lifetime Sicily was a hotspot for both geological and political events.
