Review Questions

• How did ancient Mesopotamian societies use astronomy in their daily lives?
  • Ancient Mesopotamian societies relied heavily on astronomy for agricultural planning and religious practices. They observed celestial bodies to determine the best times for planting and harvesting crops, which were essential for their sustenance. Additionally, they connected celestial movements with astrological beliefs, using these observations to guide decisions related to governance and daily life.
• What role did Islamic scholars play in the advancement of astronomy during the Islamic Golden Age?
  • Islamic scholars played a vital role in advancing astronomy by translating Greek texts and building upon earlier knowledge. They established observatories where precise observations could be made, allowing them to create detailed star catalogs. Their innovations included improvements in instruments like the astrolabe, which facilitated navigation and enhanced understanding of celestial movements. This period marked a significant advancement in both theoretical and practical astronomy.
• Evaluate the impact of Babylonian astronomical practices on later astronomical developments in Europe.
  • Babylonian astronomical practices had a profound impact on later European astronomy by laying foundational concepts in mathematical techniques and observational methods. The Babylonians developed systematic approaches to track celestial movements, which influenced Greek astronomers like Ptolemy. The translation of Babylonian texts during the Islamic Golden Age further transmitted this knowledge to Europe, setting the stage for the Renaissance's scientific advancements. This legacy highlights how early astronomical practices shaped future explorations into the cosmos.
