On the Revolutions of the Celestial Spheres

"On the Revolutions of the Celestial Spheres" is a groundbreaking work by Nicolaus Copernicus published in 1543. It proposes a heliocentric model of the universe, suggesting that the Earth and other planets revolve around the Sun, rather than the traditional geocentric view, which placed the Earth at the center. This shift fundamentally changed our understanding of the cosmos, challenging long-held beliefs and paving the way for modern astronomy. Copernicus's ideas eventually influenced other scientists, like Galileo and Kepler, and played a crucial role in the Scientific Revolution, altering humanity’s perspective on its place in the universe.
