Copernicus's A Very Liquid Heaven

481 Words2 Pages

In the pre-Copernican era, geocentrism was the paradigm for astronomers and philosophers. There were some thinkers, such as Aristarchus and Oresme, prior to Copernicus who advocated for heliocentrism or other models. However, the majority of philosophers and scientists held on to the physics and models of Plato, Aristotle, and Ptolemy. Nicholas Copernicus caused the paradigm shift from the idea that the Earth is stationary and central, to the idea that the Earth rotates and revolves around the sun. In De Revolutionibus Orbium Caelestium, Copernicus explains his stance on the shapes, movements, sizes, and positions of celestial objects (Danielson 104). Regarding the movement of celestial objects, he says that all heavenly bodies, including the Earth, move in circular paths. There are, however, inconsistencies that challenge that idea, such as retrograde motion, variable speeds, and variable apparent distances. Copernicus explains these inconsistencies simply: these irregularities appear in heavenly bodies because “Earth is not at the center of their circles of revolution” (Copernicus …show more content…

Even after his time, though, some thinkers still held on to the idea of a stationary Earth. One such philosopher is René Descartes. In A Very Liquid Heaven, he references Copernicus, stating, “I will be more careful than Copernicus not to attribute motion to the earth” (Descartes 191). Descartes believed the heavens were made of some liquid substance, and all bodies in the cosmos were suspended in it. The Earth is at rest in this liquid, and, in Descartes’ mind, there are no observations to counter that claim. However, the liquid moves but the Earth moves with it and does not change position relative to the liquid surrounding it. Therefore, Descartes states that the Earth is definitely at rest based on his definition of movement as a change in position relative to surroundings (Descartes

Such as the way people thought the layout of the universe was. There were two different ways it was assumed to look either in the favor of Ptolemy or Copernicus. “He developed a theory of the universe that was adopted by most scholars” (Doc C). The difference in scientific information from the Renaissance to the Middle Ages verified how statistics has developed throughout time. Roman astronomer, Ptolemy, developed a geocentric (Earth-centered) model of the universe which was believed to be true by most scholars (Doc C).

Analysis of Galileo’s Letter to Grand-Duchess Christina During the time that Galileo wrote the letter to Grand-Duchess Christina, there was much debate about the orientation of the universe. There were two different theories of thought at this time. One was the Heliocentric Universe, which believed the sun was the center of the universe and the Earth orbits it.

In the 1500s and 1600s, the scientific revolution changes the way Europeans looked at the world, they began to make conclusion based on experimentation and observation instead of accepting traditional ideas. ‘’Although new knowledge emerged in many areas during the sixteenth and seventeenth centuries, including medicine, chemistry, and natural history, the scientific achievements that most captured the learned imagination and persuaded people of the cultural power of natural knowledge were those that occurred in astronomy.” (348) Nicolaus Copernicus was a polish astronomer who published On the Revolutions of the Heavenly Spheres, were he made two main conclusions, the universe is heliocentric not geocentric and the earth is one part of many

Galileo Galilei was an Italian astronomer who disagreed with the Roman Catholic theory of geocentrism. He was not a heretic because he was a Christian and had similar beliefs to the Roman Catholics, but he did not agree with the Church’s theory of the position and movement of Earth in the Solar System. Document A is an excerpt of a letter to Duchess Christina of Tuscany written by Galilei, counter-arguing the heresy claims. In the letter, Galileo wrote, “Can an opinion be heretical and yet have no concern with the salvation of souls?” Although he did not believe in the astronomical theory of the Church, he believed that his scientific thoughts should not interfere with his religious beliefs.

The Scientific Revolution in the seventeenth century brought about significant changes in how people understood and approached scientific knowledge. Two specific examples of scientific discoveries that support Bernard Cohen's argument about the shift in scientific inquiry are: One example is the discovery of heliocentrism by Nicolaus Copernicus. In the late Middle Ages, the prevailing belief was in the geocentric model of the universe, where Earth was considered the center of the solar system. However, Copernicus's heliocentric model proposed that the Sun, not the Earth, was the center of the solar system. This discovery challenged the traditional knowledge based on faith and insight, as it was backed by critical observation and mathematical

For instance, Roman astronomer; Ptolemy developed the “Geocentric” theory of the universe, in which the Earth was believed to be in the center of the universe. (Doc. C) Furthermore, polish astronomer; Nicolaus Copernicus, who relied on mathematics and observations created a different understanding of the universe, called the “Heliocentric” universe. Heliocentric meaning “sun-centered,” in other words meaning that the sun is believed to be at the center of the universe unlike the Geocentric theory. (Doc. C)

As time went from the 16th century to the 18th century, the Renaissance thinking transformed to the Scientific Revolution. Soon, it would enable a worldview in which people were not invoking the principles of religion as often as the Renaissance. As an example, these natural philosophers, known as scientists today, developed a new thinking in which the world was no longer geocentric. The thought of an Earth-centered universe as the Bible would say, transformed as heliocentric or in other words Sun-centered. Within this period, Scientists were starting to understand the world’s functions, for they created experiment methods incorporating discipline, mathematics, and the essential Scientist communication.

Autumn Stern Galileo Trial Summary + Copernicus Write Up In the early 17th century, there was no doubt that the Catholic church held extreme power throughout Europe. They also held to the geocentric theory (all planets, heavenly bodies and the sun revolving around the earth) put forth by Ptolemy and Aristotle because of how neatly it could fit into the current teachings. Unlike this theory, however, Galileo enforced Copernicus’ heliocentric theory with inductive reasoning rather than deductive. Galileo made observations about the moons of Jupiter and their orbit around Jupiter, which he likened to a smaller version of their solar system.

During the Middle Ages a Roman Astronomer named Ptolemy came up with the theory that all surrounding planets orbited around the Earth. Advancement in telescopes and technology helped Copernicus during the renaissance create a more logical and accurate theory which stated how the sun is in the middle of our universe and all planets orbited the sun. This changed the way man thought because it realized how small Earth is compared to the rest of the solar system and how we may not be

In other words an immobile object will maintain immobile, unless it is caused to move. Aristotle’s words stated that the world could not have just been there for eternity it had to have a beginning. The planets spin at a perfect angle, direction, and follows the exact same pattern every time. Our solar system could not have just began moving in a perfect and precise location because

Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas.
