Sci & Tech Chronology: In the year 470 bce

Astronomy

Greek philosopher Anaxagoras of Clazomenae [b. Clazomenae, Ionia (Turkey), c. 500 bce, d. Lampsacus (Turkey), c. 428 bce] claims that heavenly bodies are made of the same stuff as Earth and that the Sun is a large, hot, glowing rock. He explains eclipses of the Sun and Moon in terms of Earth or the Moon casting a shadow. See also 3000 bce Astronomy.

Physics

Anaxagoras postulates that a large number of "seeds" make up the properties of all materials. Creation came when Earth expelled all the heavenly bodies into space. See also 530 bce Physics.
