PART 1: THE ROOTS OF MATHEMATICS
PART II: THE ROOTS OF ASTRONOMY AND COSMOLOGY
Solar Years vs Lunar Years – Synchronizing the Clocks of Heaven
The Concept The lunar cycle (354 days) and the solar cycle (365 days) do not match. You need to [...]
Identifying Planets (Grahas) – The Wanderers of the Night Sky
The Concept Distinguishing planets from stars: Planets move around, whilst stars stay in one location. The Story To the [...]
