Eratosthenes During The Scientific Revolution

786 Words4 Pages

The Scientific Revolution was the beginning of questioning tradition and the end to many unanswered questions. We’ve come a long way since Eratosthenes (276-194 BC) proved that the earth’s surface was round by measuring the shadows of two sticks near the city of Alexandria. Although Eratosthenes may have started the concept of viewing the Universe differently, the discoveries of astronomers during the Scientific Revolution was the turning point of a common man’s mind. In 1543, a document authored by Nicholas Copernicus was published that changed the way the solar system was and still is viewed. Before Copernicus, the Church had everyone believe in Ptolemy’s Geocentric Theory, which stated that the earth was in the center of the universe and the sun revolves around it. A new correct theory was brought about by Copernicus called the Heliocentric Theory. The Heliocentric theory states that the sun is the center of our solar system and the earth and other planets orbit the sun. …show more content…

Because of his lack of mathematical abilities, he had no idea how to decipher any of his observations. After his death, his assistant Johannes Kepler took over his studies. Unlike Brahe, Kepler was a “brilliant mathematician, and was inspired by his belief that the universe was built on mystical mathematical relationships.” (google.com) Kepler was able to compile three laws about planetary motion from Brahe’s observations which modified Copernicus’s beliefs. The first law states that all planets orbit the sun elliptically, and not circularly like Copernicus thought. The second law states that different planets travel at different speeds around the sun. The third law states that the time it takes each planet to complete its orbit is correlated to its distance from the

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

Nicolaus Copernicus Accomplishments

For approximately 14,000 years before Nicolaus Copernicus’s work was given credence to by the public, Ptolemaic system of astronomy had been the dominant teachings of the Catholic Church (that the earth was the center of gravity and other celestial bodies revolved around it, i.e. geocentric), even though, A. Mark Smith wrote in World Book, “[a] Greek astronomer Aristarchus had even suggested that the earth and all other planets moved around the sun” (Smith 1039). However, Copernicus was able to prove that Ptolemy was wrong, and he, determinedly, became the father of modern astronomy. Nicolaus Copernicus (born Mikołaj Kopernik) was born in Thorn (now Toruń, Poland) on February 19, 1473. Encyclopedia Americana apprises that, “[Copernicus] studied

In the 1540, a new view on science rose, this view led to modern science, known as the Scientific Revolution. The Scientific Revolution is an historical change in thoughts and beliefs about science. There were many smart people alive during the Scientific Revolution but the person, Nicolas Copernicus, was probably one of the smartest around in his time. He was an astronomer ,but one day he noticed from his observations was that there was something wrong with the geocentric theory. His discovery was the lead to the Scientific Revolution.

It has taught the next astronomers about the movement of the celestial objects and how to make accurate predictions on their positions. For example, the Islamic astronomers welcomed the Ptolemaic chart into their work. Nicolaus Copernicus (1473-1543) switched the positions of the Earth and the Sun and then created the heliocentric model. In this system, the speed and motions of celestial bodies were modified. In the next few years, Johannes Kepler (1571-1630), took inspiration from the heliocentric model to formulate Kepler’s laws of planetary motion.

Lauren King Tom Mundinger Galileo Essay February 1, 2023 Galileo Galilei Galileo was the most influential figure in the Renaissance era. Galileo was a remarkable man who contributed greatly to our understanding of the heavens above. He is often referred to as the “Father of modern science” for his groundbreaking discoveries in the fields of astronomy and physics. Galileo’s brave rejection of traditional views about the universe, his experimental observations of the stars and planets, and his relentless questioning of accepted knowledge marked a turning point in science and philosophy. This essay will look at Galileo’s accomplishments and their impact on science, both during and after his lifetime and beyond.

Explain The Three Laws Of Astronomy Discovered By Johannes Kepler

267 Words | 2 Pages

The three laws of astronomy discovered by Johannes Kepler are; the orbits of the planets are ellipses with the sun as one of the foci, an imaginary line drawn from a planet to the sun sweeps over equal areas in equal intervals of time, a planet's orbital period squared is proportional to its average distance from the sun cubed. These three laws provide mathematical support for how the planets orbit the sun, as well as explaining the apparent backwards motion of neighboring planets. Kepler's first law, which explains the orbits of the planets as ellipses, is important for several reasons. This explanation for planet's orbits explains the apparent backwards motion of neighboring planets, as well as providing solid support for a universe in

Kepler was born prematurely on “December 27, 1571, in Weil der Stadt, Swabia '' (Jeremy,pg 1). His interest in science began when his mother took him to see a comet as a child. As a scientist Kepler used a progressive way of thinking along with physics to show the universe moves in a certain way. Kepler believed in the sun being in a fixed position in space like Copernicus.

Heliocentric was having the planets revolve around the sun and the geocentric model was having the planets and the Sun revolve around the Earth. During the middle ages the geocentric model was accepted by scientists such as Eudoxus and Ptolemy, as well as the everyday people because it justified that humanity’s home was in the most important place in the universe. However. During the Renaissance new scientific discoveries were made by Galileo Galilei, Nicolaus Copernicus, Tycho Brahe, and Johannes Kepler that argued the universe was based on heliocentrism. Though all scientists contributed valuable study and information to the notion of which model was correct, it was Johannes Kepler that cracked the code about the correct type of model and how Ptolemy was wrong about the motion of the planets.

He realized that a planet moved slower farther away from the sun than it did when closer. Once he understood that planets traveled in ellipses, he determined that a line connecting the sun to a planet covered an equal amount of area over the same amount of time. This is Kepler’s Second Law. Kepler's Third Law was published a decade later, and recognized the relationship between the periods of two planets and their distance from the sun.

Galileo supported the Heliocentric theory, and he was told to not publicly say that he supported the Heliocentrism by the Church, however, Galileo could not remain quiet, and publicly advocated for Heliocentrism. It is even widely believed that Galileo said, “And yet it moves", and in this quote, it is believed that Galileo was referring to the Earth, saying that the Earth was not in a state of fixation, rather, it revolves around the Sun. Galileo had also once said, “The Bible shows the way to go to heaven, not the way the heavens go”, meaning

Describing his third, and arguably his most important law. As described by kepler.nasa.gov “the squares of the periodic times are to each other as the cubes of the mean distances.” Referred to as the law of harmonies, it compares the radius of orbit of one planet to those of another planet. Contrasting his first two laws that described motion characteristics of one planet at a time, his third law makes a evaluation between the motion of various different planets. The comparison being made is that the larger an orbit is the slower the average velocity of an orbiting object will be.
