Alexandria was the city founded in BC 332 by Alexander the Great. The construction work started by him was left unfinished and his army commander Ptolemy completed it after his death.
The city of Alexandria itself is a prime example of Greek science and technology. The buildings, palaces, roads, libraries and fairways found in this city were the best evidence of the technical prowess of the Greeks.

The Story of Archimedes
Archimedes was the greatest scientist who lived in
Alexandria. He invented the famous law of buoyancy and Archimedes principle and
announced it to the world.
This is a very old science story. But do you know what
scientific philosophy he invented? When a solid is immersed in a liquid without
resistance, the weight of water displaced by the solid is equal to the weight
of the solid.
Nobody can forget Archimedes and his story of discovering
this scientific fact. He also carried out many astronomical researches. He
built a planetarium for astronomical research. He did much research on solar
eclipses and lunar eclipses.
