Summing Up & Moving On

During the first two weeks of January, we followed ancient humans through time as they discovered/invented fire, tools, housing, agriculture, clothing, weapons, laws, transportation, and art. With few exceptions, the identities of the inventors/discoverers are unknown. As prehistory became history, the identities of those who made discoveries/inventions are known. For the rest of the month, we will feature the progress of science and inventions by scientists and inventors—in no particular order.

Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily which was part of Greece. He may have studied in Alexandria, Egypt which was known as a center of learning. Archimedes was killed circa 212 BC when the city was captured by Rome after a two-year-long siege.  Archimedes was one of the leading scientists in classical antiquity and one of the greatest mathematicians of all time.

His advances in physics include the foundations of hydrostatics, statics and an explanation of the principle of the lever. He invented innovative machines, including siege engines, a planetarium, the screw pump still used today (see pic) and machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors. He also designed the largest ship of the time, the Syracusia, which could be used for luxury travel (it could accommodate 600), carrying supplies, and as a naval warship.    Until Tomorrow, Rita Bay
