In his book, Repcheck recounts how a Catholic Church cleric invented a highly complicated theory of the heavens’ architecture. Copernicus made a breakthrough by solving a significant astronomical problem. Everybody except the astronomers had earlier accepted Aristotle’s concept that heavenly objects revolved around the earth in perfectly circular orbits. The astronomers were opposed to this notion since their calculations could not work according to it. Repcheck introduces Ptolemy who described a cosmos in which the earth positioned itself somewhat off-center and other heavenly bodies revolved in one circular orbit inside a second ideal circle at changeable speeds. Even though Ptolemy’s model was rather complicated, astronomers found it to be reasonable in their calculations. Astronomers were still using this new concept even 1500 years later. In this regard, the author starts to bring Copernicus into the picture.
“Upon this principle they imagin'd the earth rested in the center of the Universe,” the book said, “while all the celestial bodies (which were made for it) took the pains to turn round to give Light to it. They plac'd the Moon above the Earth, Mercury above the Moon, after Venus, the Sun, Mars, Jupiter, Saturn; above all these they set the ...
Nicolas Copernicus died never knowing what a revolution he made in the scientific world. Mathematicians and scientist like Ptolemy, Newton, and Brahe supported his heliocentric theory. He was born in Poland on February 19th, 1473 the baby of four children. His father was Nicholas Copernicus Sr. died in 1483 when Copernicus was at the young age of ten. He and his sibling went to live with his Uncle Lucas Waltzenrode the bishop of Warmia in Germany. His family’s exceptional wealth allowed him to attend some of the finest schools in Europe. After attending Cracow for mathematics he went to Italy to study canon law. Under the influence of his uncle he become a canon, which is just below a bishop. In Italy he made his first astronomical observation one night with a friend who was a professor of astronomy. Copernicus explored many occupations: a canon, mathematician, and the one he is most known for astronomer.
Galileo Galilei and the religious authorities represent the clash between the new ideas and old ideas of the 17th century. Galileo Galilei represents the new ideas with his heliocentric theory, and the religious authorities represent the old ideas while demanding that Galileo Galilei’s ideas are false because the Bible says that the earth is the center of the universe. Galileo Galilei said, “They know that as to the arrangement of the parts of the universe, I hold the sun to be situated motionless in the center of the revolution of the celestial orbs while the earth revolves about the sun. They know also that I support this position not only by refuting the arguments of Ptolemy and Aristotle, but by producing many counter-arguments; in particular, some which relate to physical effects whose causes can perhaps be assigned in no other way.”(3:1) This provides infor...
In the sixteenth and seventeenth century a Scientific Revolution swept over Europe. The start of this Scientific Revolution has been atributed to Nicolaus Copernicus and his Heliocentric Model of the Universe.
Named after Nicolaus Copernicus the Copernican principle states that Earth is not situated in a favored or central position in the universe (Bondi, 1952). It is a shift from the Ptolemaic system which states that the earth is at the center of the universe and dates back to the 16th and 17th century. The Copernican principle is one of the primary principles in astronomy. It states that the sun is the center of the solar system. Copernicus was not satisfied with the earlier system and created a heliocentric model which demotes Earth from its central role in the universe (Kuhn, 1957). The Copernican principle implies that the universe appears isotropic in all directions from Earth which also implies that the universe is homogenous everywhere. This statement contradicts with modern astronomy which observes that the universe is ...
The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s
As Copernicus began to study astronomy more, he came to strongly disagree with the Ptolemaic system of astronomy. This system was based on the idea that the earth was fixed in the center and all the other heavenly bodies moved around it. Astronomers believed that the earth was in the center because it was heavy. Copernicus saw many problems associated with this system of astronomy. For example, sometimes the planets appeared to be going in the opposite direction and the brightness of the planets would tend to change as well.
Until Copernicus, the teachings of the Greek astronomer Ptolemy were considered the indisputable truth. His idea was that the Earth was the stationary center of the universe. The sun, moon, planets, and th...
Galileo was born in February of 1564 to a poor family that resided in Pisa, Italy. Galileo’s father was a composer and musical therapist, but he also supported his family through working in the wool trade. Galileo and his family moved to Florence, Italy in the 1570s, and here Galileo began to attend

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves around the sun. The notion is as old as the ancient Greeks however. This work was entrusted by Copernicus to Osiander, a staunch Protestant who though the book would most likely be condemned and, as a result, the book would be condemned. Osiander therefore wrote a preface to the book, in which heliocentrism was presented only as a theory which would account for the movements of the planets more simply than geocentrism did, one that was not meant to be a definitive description of the heavens--something Copernicus did not intend. The preface was unsigned, and everyone took it to be the author’s. That Copernicus believed the helioocentric theory to be a true description of reality went largely unnoticed. In addition to the preface, this was partly because he still made reassuring use of Ptolemy's cycles and epicycles; he also borrowed from Aristotle the notion that the planets must move in circles because that is the only perfect form of motion.
Much to the dismay of the Church, two astronomers Galileo and Kepler had the audacity to challenge the authorities by suggesting that the sun-not the earth-was at the center of the universe. The church had a stronghold on the way the spiritual and physical world worked, so these discoveries only added to the Church’s resistance to their aims. Their discoveries came only after Kepler and Galileo began to question ancient theories about how the world functioned. These ancient truths were widely held but were inconsistent with the new observations that they had made. Kepler had discovered the laws of planetary motion which suggested that the planet would move in elliptical orbits, while Galileo followed with his discovery of the principle of inertia. Galileo concluded his finding b...
The Copernican Revolution Planetary Astronomy in the Development of Western Thought by Thomas S. Kuhn, is a book that illustrates the importance between man and the natural world from antiquity to the current date. Thomas Kuhn vividly shows us that the Copernican revolution was not only a revolution of scientific theory, but of religious, and conceptual thought as well. Kuhn states in the opening lines of his book that "The Copernican Revolution was a revolution of ideas, a transformation in man's conception of the universe and his own relation to it." Kuhn aims to show us that the transformation of Aristotle's unique, and immobile centre of the universe, to Copernicus' third rock from the sun, had an enormous effect on what we believe and value today.
