Views of the World in History ● In Old Hindu believes the Earth is flat and is resting on 3 giant elephants, which in turn stand on the back of a gigantic turtle. ● Ancient Maya viewed the world as a sacred tree giving rise to the Earth surrounded by primordial ocean.

Thales of Miletus (C BC) - Founded the scientific school in Miletus - Believed that Earth floats on water like wood - Probably viewed Earth as spheric - Has predicted a solar eclipse Miletus (Μίλητος)

Ancient Greek View of the World Anaximander (c BC) Hecataeus of Miletus (c BC) Eratosthenes of Cyrene ( BC)

Aristotle (384 BC – 322 BC) - There are stars seen in Egypt and Cyprus which are not seen in the northerly regions. - Travelers going south see southern constellations rise higher above the horizon. - The shadow of Earth on the Moon during a lunar eclipse is round.

Latitude and Longitude - Coordinates: Latitude and Longitude - Trigonometry and First Trigonometric Tables - Astronomical Methods of Determination of the Positions of Objects - Motion of Sun and Moon Hipparcus c. 190 BC – 120 BC Iznik (Nicaea)

Claudius Ptolemy (c AD) Mathematics Astronomy and Astrology Geography Optics Music Weltanschauung
