What scientific advancement did the chaldeans make

The scientific advancement that the Chaldeans made was the development of a new empirical method to Astronomy (the study of celestial objects).

Explanation:

The Chaldeans were people who lived in Chaldea (Mesopotamia) around the 10th century BCE, before being assimilated into Babylonia. The astronomers that lived here started studying and recording the movements of the moon, planets and constellations to try and explain the natural rules of the universe and their beliefs. This became their "empirical" approach, since they used their senses to receive information (observation of patterns and behaviours).
