Archimedes Greek scientist Archimedes (Ancient Greek: Ἀρχιμήδης Archimedes বর্তমান , now Greek Αρχιμήδης Archimedes) or Syracuse Archimedes (26-212 BC) is a Greek mathematician , physicist , engineer , and astronomer. Although little is known about his life , he is considered one of the best scientists of the classical age. His notable contributions to physics include laying the foundations of ecology and flowing ecology, and giving detailed explanations of liver function. He is also famous for designing basic equipment such as Archimedes screw pumps for lifting water , siege engines for wartime attacks . Modern scientific experiments have made it possible to successfully set fire to ships with the help of his designed attack ship lifting device or a set of mirrors placed side by side. Archimedes is generally regarded as one of the greatest mathematicians of all time and one of the greatest mathematicians of all time. He determined the area under the parabola curve as an aggregate of infinite currents using the method of extrusion and determined an almost perfect value of pi. He also defined the spiral of Archimedes , provided a formula for determining the area of a curve, and discovered an excellent method for easily expressing many large numbers. Although the Romans were forbidden to do any harm to Archimedes , Archimedes was killed by a Roman soldier during the Roman siege of Syracuse. The Roman philosopher Cicero mentions a sphere enclosed inside a cylinder above the tomb of Archimedes. Archimedes proved that the volume of the sphere enclosed inside the cylinder and the area of the ground were both two-thirds of the cylinder , which is considered one of the best mathematical achievements of Archimedes. In ancient times, Archimedes' mathematical compositions were not as well known as his inventions. Alexandrian mathematicians read his writings , citing them in various places , but the Greek architect Isidore of Miletus was the first to record all his works together in about 530 AD. Later, in the sixth century, the Greek mathematician Eutosius Archimedes published an account of his work , which introduced him to a wider readership for the first time. Very few written documents of Archimedes' work remained after the Middle Ages. But those few documents are considered to be very useful to later Renaissance scientists. In 1906 a new manuscript of Archimedes was discovered which sheds new light on his method of solving mathematical problems. Source: Wikipedia.
