What were key milestones of the Scientific Revolution?

• A. The invention of the telescope and steam engine as the core milestones.
• B. The development of calculus as the foundation of science.
• C. Copernicus, Galileo, and Newton; shift to empirical inquiry and mathematics; challenge to church authority.
• D. The belief that observations were unnecessary for truth.

Answer: (C)

The major idea tested is a shift from relying on ancient authorities to understanding the natural world through careful observation and mathematics, along with a change in how science related to established power structures. Copernicus proposed a heliocentric cosmos, which reframed the universe and opened the door to new questions. Galileo used the telescope to gather empirical evidence—noting phases of Venus and moons around Jupiter—to show that the heavens could be studied and that observations could challenge traditional doctrines. Newton then tied things together with universal laws of motion and gravity, using mathematics to describe both the heavens and the Earth in a single framework. This combination—empirical inquiry, mathematics as a language of nature, and a challenge to ecclesiastical authority over cosmic matters—best captures the milestones of the Scientific Revolution.

While the telescope mattered and calculus became a powerful tool, the most accurate summary focuses on the people, the methodological shift, and the questioning of authority. The idea that observations were unnecessary runs counter to the whole revolution in how knowledge was pursued.
