Who invented technologies requiring knowledge of physics? (Ancient Greece)

Archimedes is likely the best known.

Explanation: He invented many of the War machines used; used natural petroleum pools for Greek Fire. Had an understanding of density of materials.

The correct answer is Archimedes

Archimedes was born in Syracuse, present-day Italy, in 287 BC. He was a Greek mathematician, engineer, physicist, inventor and astronomer, the son of an astronomer, who probably introduced him to mathematics. Archimedes studied in Alexandria, where he had Canon de Samos as his master, and thus came into contact with Erastotenes. Archimedes dedicated his method to this last one, in which he exposed his brilliant application of mechanics to geometry, in this way, he "imagined" unknown areas and volumes to determine their value. He soon returned to Siracusa, where he devoted himself entirely to scientific work.

Archimedes' various warlike inventions are famous, which are believed to have helped Syracuse to resist Roman siege for three years before falling into the hands of Marcelo's troops.
