The belief that the Earth is fixed at the center of the Universe, and the sun, moon, stars and even the planets revolve around our planet
Geocentric view
The earth and the heavenly bodies are spheres, and the earth is the center of the universe
Heliocentrism
The astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System
Heliocentric view
The earth is not the center of the universe, and it is just part of the universe
Aristarchus of Samos introduced the heliocentric view of the universe
c. 310 – c. 230 BC
The heliocentric view was not accepted, instead, the geocentric view was more accepted because it is more reasonable during the time of Aristarchus
Nicole d' Oresme wrote "The Book of Heaven and Earth", supporting the heliocentric view of the universe
1370
The geocentric view prevailed again, as the heliocentric view was against the church and its prevailing belief of geocentrism
Nicolaus Copernicus reintroduced the concept of heliocentric view with his book "De Revolutionubus Orbium Colestium"
16th century
Nicolaus Copernicus
Stated that the earth is not the center of the universe, the center of the universe is near the sun and the earth-sun distance is negligible compared to the distance to the stars
Tycho Brahe
Fused concepts from geocentric view and heliocentric view to propose the geoheliocentric view
Tycho Brahe lost part of his nose at a sword fight with his third cousin, Manderup Parberg, because of a mathematical equation
Johannes Kepler
Proposed three laws of planetary motion and provided evidences to strengthen the heliocentric view, saying that his faith, empirical data, and elegant math all sync
Galileo Galilei did not invent the telescope, it was invented by a Dutch spectacle maker Hans Lippershey in Holland, but Galileo was the first to enhance the scientific instrument and use it to understand the universe
Galileo Galilei
Called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science"
The Copernican intellectual revolution did not die along with Copernicus, it became a progressive series of events which eventually led to the birth of modern astronomy
Science is not a one man team, it is a team effort, based on the series of events and contributions of various astronomers, which has led to our current understanding of the universe
The Copernican intellectual revolution changed the way we view not only the world, but also the universe
Heliocentric model suggests that the planets orbit the sun instead of the earth.
Heliocentric model - Sun is at the center
Copernicus' work on astronomy challenged traditional beliefs about the universe, leading to significant changes in scientific understanding.
Copernicus' work challenged the traditional view that Earth is at the center of the universe, with the Sun revolving around it.
The Copernican Revolution was the shift from geocentrism to heliocentrism.
Copernican Revolution refers to the shift from geocentrism (earth at center) to heliocentrism (sun at center).
Geocentric Model - Earth is at the center
Galileo Galilei was an Italian scientist who made important discoveries using his telescope, including observations of the moon, stars, and Jupiter's moons.
Copernican Revolution - Heliocentric model was accepted as true
Copernicus proposed that the Sun was actually at the center of the solar system, with the Earth and other planets orbiting around it.
Ptolemy's Geocentric Model - The geocentric model proposed by Ptolemy suggested that all celestial bodies revolved around the Earth.
Johannes Kepler was a German mathematician and astronomer who developed laws describing the motion of planets around the sun.
Geocentric Model - Earth as Center of Universe
Geocentrism refers to the belief that the Earth is at the center of the Universe.
Heliocentrism refers to the belief that the Sun is at the center of the Solar System.
Ptolemy's Geocentric Model - Earth at Center of Universe
Galileo Galilei was an Italian physicist, mathematician, engineer, philosopher, and astronomer known for his contributions to the scientific revolution.
