Anaximander (610-546 BC) was the second of the scientists or philosophers who lived in Miletus, like Thales. According to historical documents, he was the best scholar in Astronomy and Geography.
Cosmogony – Cosmology – Astronomy
Anaximander explained the creation of the world beginning from the infinite (Apeiron). He considered that the stars are condensations of gases and fire which are created from swirling.
In Astronomy, Anaximander made sundials. According to Anaximander, the Earth, which is in the middle of the universe, is a sphere with width triple than its length and people live on its surface. Anaximander also formed a theory that life on Earth appeared because of the heat from the sun. The first creatures were like fish and they had shells. People appeared at the end of this stage.
Anaximander believed that the wind was moving air and the rain came from the Earth’s streams. The clap of thunder appears from air escaping from the clouds and when air crashes with clouds, a flash of lighting is created.
The centre of Anaximander’s philosophy was infinity (Apeiron), which has two explanations:
- the infinite, and
- the limitless.
