The event that marked the beginning of the scientific revolution is often identified as the publication of Nicolaus Copernicus's "De revolutionibus orbium coelestium" in 1543. This work proposed a heliocentric model of the universe, challenging the long-held geocentric view that placed Earth at the center. Copernicus's theory sparked profound changes in scientific thought and encouraged further inquiry into astronomy, mathematics, and physics. This period of intellectual transformation emphasized observation, experimentation, and rational analysis, laying the groundwork for modern science and influencing notable figures like Galileo Galilei and Isaac Newton in their subsequent discoveries.
