1. Galileo improved the design of the telescope in the early 17th century, which allowed him to make groundbreaking astronomical discoveries, including the moons of Jupiter.
2. He is credited with formulating the law of falling bodies, demonstrating that objects fall at the same rate regardless of their mass, which laid groundwork for understanding gravitational effects in atmospheric science.
3. Galileo's observations of sunspots and the phases of Venus provided critical evidence for heliocentrism, altering humanity's perspective on the universe.
4. His work emphasized empirical evidence and experimentation over philosophical reasoning, promoting a new approach to scientific investigation that is foundational in atmospheric studies.
5. Galileo faced significant opposition from religious authorities for his support of heliocentrism, which highlighted the conflict between science and religious dogma during his time.

Review Questions

• How did Galileo's improvements to the telescope influence the field of atmospheric science?
  • Galileo's enhancements to telescope technology allowed him to observe celestial bodies with unprecedented clarity. This advancement enabled him to document details about planets and their atmospheres, contributing to a deeper understanding of their composition and behavior.
