Who? Archimedes


Archimedes was an ancient Greek
mathematician, physicist, engineer,
inventor,and astronomer. He was a leading scientist in his days, and was responsible forexplaining the lever and many inventions. He gave a very accurate approximation of
pi. He figured out that you could find out
the density of something by placing the object in water.
He also invented a revolving screw/cylinder that was
pumped by hand to move water uphill. It is still used. He
invented a weapon that lifted enemy ships up in the air andsunk them, which has been proved to work. He showed
us many things that help us live our lives today.
