The answer took a while for astronomers to figure out, leading to a debate between what is known as the geocentric (Earth-centered) model and the heliocentric (Sun-centered model). ... The Earth was in the center of it all (geocentric), with these planets revolving around it.

The Dutch polymath and horologist Christiaan Huygens, the inventor of first precision timekeeping devices (pendulum clock and spiral-hairspring watch). From its invention in 1656 by Christiaan Huygens until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use.

Developed from the 1950s through the 1970s, plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didn't have an explanation for how continents could move around the planet, but researchers do now.

The geocentric model could not fully explain these changes in the appearance of the inferior planets (the planets between the Earth and the Sun). ... His second law states that for each planet, In ancient geocentric theory, Earth was the center of the universe, and the body around which the Sun and planets revolved.

This theory states that the center of the universe is the sun and it was founded by a Polish astronomer named Copernicus. ... When the sun, moon, and earth are aligned in that order in a straight line and where the sun's light is completely covered by the moon.

The Scientific Revolution began in astronomy. Although there had been earlier discussions of the possibility of Earth's motion, the Polish astronomer Nicolaus Copernicus was the first to propound a comprehensive heliocentric theory equal in scope and predictive capability to Ptolemy's geocentric system.

The theory was first put forward in 1948 by British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle. It was further developed by Hoyle to deal with problems that had arisen in connection with the alternative big-bang hypothesis.

After only 18 months, Brahe mysteriously died. Kepler continued to use Brahe's observations and developed his Laws of Planetary Motion with them. Eventually, astronomers like Kepler, Galileo, and Isaac Newton disproved the geocentric view of the earth at the center of the universe once and for all.

The geocentric model could not fully explain these changes in the appearance of the inferior planets (the planets between the Earth and the Sun). Furthermore, Galileo's observations of Jupiter's moons made it clear that celestial bodies do move about centers other than the Earth.

Johannes Kepler published his first two laws about planetary motion in 1609 , having found them by analyzing the astronomical observations of Tycho Brahe. Kepler's third law was published in 1619. ... His first law reflected this discovery.

Systems theory was proposed in the 1940's by the biologist Ludwig von Bertalanffy and furthered by Ross Ashby (1964). Von Bertalanffy was reacting against both reductionism and attempting to revive the unity of science. He is considered to be the founder and principal author of general systems theory.
