What are some of the scientific advances made by the chaldeans?

The Chaldeans, particularly during the Neo-Babylonian period, made significant advances in astronomy and mathematics. They developed a base-60 number system, which is still used today for measuring time and angles. Their observations of celestial bodies led to early forms of Astrology and the recording of planetary movements, which laid the groundwork for future astronomical studies. Additionally, they contributed to the development of geometry and made improvements in methods for predicting eclipses.
