What have people observed in the sky since long before recorded history?
Sun, Moon, Stars, Planets
Ancient Observations - which are still useful!
Ancient Cosmologies - facts or invention?
- Problem of the Planets (Wanderers)
- The strange motion of the planets exemplifies two competing world views

- Astronomy searches for explanations in simple laws - leads to new science
