Which field did Galileo's work help establish?

• A. Modern physics
• B. Economics
• C. Political science
• D. Oceanography

Answer: (A)

By focusing on observation, measurement, and mathematics to explain how things move and what we see in the heavens, Galileo helped establish the approach that defines modern physics. He didn’t just propose ideas; he tested them through experiments and careful calculations, turning the study of motion and celestial bodies into something testable and repeatable. His experiments with moving objects and gravity showed that there are universal laws governing nature, which could be described with math rather than with tradition or authority. In astronomy, his telescope observations supported a heliocentric view and showed that planets and moons behave in predictable ways, reinforcing the idea that the universe operates according to discoverable laws. This blend of empirical method and quantitative description is what marks the rise of modern physics. The other fields—economics, political science, or oceanography—were not the areas where his work forged such a foundational shift.
