How many things did Nicolas coernicus invent?

Answer 1

Nicolaus Copernicus is primarily known for formulating the heliocentric model of the solar system, which posited that the Earth and other planets orbit the Sun. While he did not invent physical devices or technologies, his work laid the foundation for modern astronomy and significantly changed our understanding of the universe. His major work, "De revolutionibus orbium coelestium," published in 1543, shifted the perspective of celestial mechanics. Thus, while he may not have invented "things" in a traditional sense, his ideas were revolutionary.
