Archimedes – interesting factsArchimedes (287P-212 B.C.) was a Greek mathematician and inventor. He achieved advances in science unequaled for hundreds of years. Among his discoveries was the principle of buoyancy - an object placed in a liquid experiences an upthrust equal to the weight of liquid displaced. Legend has it that Archimedes discovered this when he stepped into a hill bath and saw water spilling over the sides. He rushed out into the street crying 'Eureka' (I have found it). He also worked out the laws of levers and pulleys. These showed that heavy loads could be moved with a small force. Archimedes regarded his calculations of the areas of circles and other curves as his most important work. Much of it is still basic to mathematics today. Archimedes was born and lived in Syracuse, Sicily. During the long Roman siege of the city, the enemy was held back by catapults which Archimedes invented. When the Romans finally entered the city, their general ordered his men to spare Archimedes. But he was killed by a soldier who failed to recognize him. You can read these articles also: |
