8. Nicolaus Copernicus (1473-1543)
Nicolaus Copernicus, a Renaissance-era polymath, is best known for his heliocentric model of the universe, which placed the Sun, rather than the Earth, at the center of the solar system. His work, De revolutionibus orbium coelestium, published in 1543, marked the beginning of the scientific revolution, challenging long-held views of the cosmos and laying the foundation for modern astronomy. Copernicus’ theory paved the way for later astronomers like Galileo and Kepler and profoundly changed humanity’s understanding of its place in the universe.
9. Galileo Galilei (1564-1642)
Galileo Galilei, often called the “father of modern science,” made significant contributions to physics, astronomy, and scientific methodology. Using the newly invented telescope, he made groundbreaking astronomical observations, including the moons of Jupiter and the phases of Venus, which supported Copernicus’ heliocentric theory. Galileo’s advocacy for the scientific method and empirical observation helped establish modern science as a field independent of religious and philosophical dogma. His conflict with the Catholic Church over heliocentrism remains one of the most famous episodes in the history of science.
10. Aristotle (384-322 BC)
Aristotle, the ancient Greek philosopher and student of Plato, made lasting contributions to nearly every field of human knowledge, including logic, metaphysics, ethics, politics, and biology. His works on natural sciences and philosophy provided the foundation for much of Western thought for centuries. Aristotle’s influence extended into the Middle Ages, where his ideas were integrated into Christian theology by thinkers like Thomas Aquinas. His views on politics and ethics continue to shape modern discussions on governance, morality, and human behavior.
