</p><p>Archimedes known for his ideas on levers, hydrostatics and infinitesimals was an engineer, physicist and a mathematician. There are many who are unaware that he was the brain behind many discoveries such as constructing a machine that could sink a ship without lifting from water and a device to set fire to a ship from a distance. He’s most known for his principle of Archimedes dealing with fluids. Archimedes principle states that when an object in immersed in a fluid, the weight of the fluid displaced is directly proportional the buoyant force on the body. Some of his other famous discoveries are : -</p><p> He explained the principle of lever system although he did not discover it. He designed the tackle and block pulley system which was used to lift heavy objects by the sailors.</p><p> Archimedes screw, another of his masterpieces was used to lift water by operating it manually.</p><p> Odometer was designed by him.</p><p> He gave the formula for finding the area of a circle.</p><p> He developed the geometric sequential series. Archimedes met his end at the hands of a Roman soldier despite orders from the king not to harm him.</p><p>
