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.
that is a nice choice well organized
