This model, presented in his book “De Revolutionibus Orbium Coelestium,” challenged the prevailing geocentric view that had dominated for centuries.
- Galileo Galilei (1564-1642) was a pivotal figure in the Scientific Revolution. He made significant contributions to astronomy, physics, and engineering. His use of the telescope led to groundbreaking observations of the Moon, the phases of Venus, and the moons of Jupiter, providing compelling evidence for the heliocentric model. His experiments on motion, including the famous Leaning Tower of Pisa experiment, laid the foundation for classical mechanics.
- Johannes Kepler (1571-1630) was a German astronomer who developed the laws of planetary motion. His work built upon Copernicus’s heliocentric model and established that planets move in elliptical orbits around the Sun, not circular ones. Kepler’s laws were crucial for understanding the dynamics of the solar system.
- Isaac Newton (1643-1727) is widely regarded as one of the most influential scientists of all time. He formulated the laws of motion and universal gravitation, which explained the movement of objects on Earth and in the cosmos. Newton’s work, published in his seminal work “PhilosophiƦ Naturalis Principia Mathematica,” revolutionized physics and laid the foundation for classical mechanics.
