Johannes Kepler's Accomplishments

Galileo might be the most famous person in the development of astronomy. He is famous, not only because of the amazing work he did to advance Copernican theory of heliocentrism, but also because of the controversy that surrounded him. Using new methods and instruments, he provided compelling new evidence to support Copernican theory. He also contributed to the development of theories of physics that could account for the movements of bodies in new terms. His observations of the movements of objects in the heavens required different explanations than the old ideas about the heavens. It required him, and others, to begin to understand the reasons to explain these new observations. His efforts to publicize his findings was met by

Johannes Kepler (1571-1630) was a German astronomer who believed in the heliocentric theory. Kepler is a clear example of the narrow line that separated science and religion. Nonetheless, his ideas would show that things could be solved through reason alone. He believed that the harmony of the human soul could be found through numerical relationships that existed between planets. He found that the planets: Mercury, Venus, Earth, Mars, Uranus, Jupiter, and Saturn all revolved at different times. For example, the earth revolved around the sun in a year while Saturn revolved around the sun in fifty years. From this, Kepler found a mathematical ratio, nine to the two-thirds power, to explain this phenomenon. This was revolutionary to humanity’s place in the universe. People were shocked that the universe could be explained by math alone rather than religion. This went strongly

the heliocentric solar system. Johannes Kepler further modified the heliocentric system, by mathematically showing that the planets’ orbits are elliptical. With his invention of the telescope, Galileo made new observations about the solar system and found mathematical laws that described the movement of the planets. Later, Isaac Newton established a universal law of gravity. With the new scientific discoveries, the gap between religion and science increased. Science revolutionized the human though and its understanding of the universe.

Isaac Newton is considered one of the most important philosophies (scientist) in history. One of the biggest accomplishments the newton created was discovering the theory of gravity. Defined in the Principia, his theory about gravity helped to explain the movements of the planets and the Sun. This theory is known today as Newton's law of universal gravitation. Also Newton's created the laws of motion were three fundamental laws of physics that laid the foundation for classical

During the time of Galileo, the church was very strict with physicists who believed in the Copernican model. This is exactly the position that Galileo found himself in. In 1600 Galileo began making his own telescope. He became the first person to point one at the night sky. What staggered him the most by doing this was the sheer volume of stars that were not visible with the naked eye. Galileo used his telescope to make many discoveries; one of these is the discovery of Jupiter’s four moons. He even plotted and tracked there rotations around Jupiter. The main thing however, was that Jupiter even had moons, this was proof that the geocentric model was incorrect and that this discovery was in favour of the Copernican model.

Johannes Kepler was a famous mathematician, best known for his works on the planetary laws of motion. During his lifetime he faced many oppositions to his work, Kepler was known to be a very quiet tempered man with little interest but his research, which was often impeded. Kepler’s personal religious beliefs were what caused him the most trouble in his professional and personal life. He was denied positions and friendships due to his Protestant beliefs; finding enemies in the Catholic church and in the Lutheran for his sympathy towards Calvinists. In addition, Kepler’s family life was increasingly problematic. His first wife often prevented him from getting work done, and two of his sons died. Finally, Kepler’s mother was accused of being a witch, this greatly affected Kepler, as he had to take time out of his research to help prove her innocence on the matter.

All his writings consisted of numerous references to God. He saw his work as a fulfilment of his Christian duty to understand the works of God. Kepler believed that God had made the Universe according to a mathematical plan. Although, Kepler did thank God for granting him insights, but the insights were still presented as rational. While studying theology at the university at Tubingen, he fell under the influence of Michael Mastlin. He then abandoned theology and became a teacher of astronomy and mathematics in Austria. Johannes Kepler’s work illustrated the narrow line that would separate magic and science in the early Scientific Revolution. Kepler compared numerical relationships between planets in harmony of the human soul. He described it as discovering the "music of the spheres." Overtime, Johannes Kepler devised the three laws of planetary motion. He confirmed Copernicus' heliocentric theory, and eliminated the scientific possibility of crystalline spheres moving in perfectly circular orbits. Eventually, Johannes Kepler’s three laws affected the eliminated idea of uniform circular motion. By the end of Kepler’s life, the Ptolemaic system rapidly lost its ground to the new ideas. Many questions do remain unanswered. However, it was an Italian scientist who achieved an important break through to a new cosmology by answering the first question and striding through the

They were important because from then and today people need to use it to do science and other daily stuff that they need to do. He also was very important to the world because if people didn't know the three laws of motion today we basically wouldn't be able to do science because that is how important he was he mad basically science because he was so smart.

Johannes Kepler was a man who made a surplus of achievements and discovery. What he is most known for is discovering that planets don’t go in a circular motion around the

Galileo was first to have the use of a telescope to observe celestial bodies, which helped him greatly in making new discoveries. He was able to not only study the motion of other planets, but was able to observe the satellites orbiting those planets. Galileo also discovered an enormous amount of stars by observing the Milky Way giving way to theorizing that there is more to our universe then what was previously thought. Galileo later found himself in trouble with the Catholic Church for publicly announcing his findings, which went against the Church’s held beliefs of the Earth’s place in our universe. Sadly, Galileo had to essentially denounce his findings and was forced to keep his discoveries private for the rest of his days.

His studies combined astronomy, physics, and religion together during a time where all three subjects were considered separate. One of his biggest contributions to physics were his three laws of planetary motion. Initially Kepler's studies were given little thought, at least until the respected astronomer Tycho Brahe invited Kepler to work with him in Prague. This allowed for him to meet with other well-known scholars, and eventually led to his discovery that the planets followed an elliptical path as opposed to a circular path that Nicolaus Copernicus had originally established. He established these discoveries in a number of books, such as Mysterium Cosmographicum Astronomiae Pars optica, and Astronomia nova. Johannes Kepler has been interesting to me because he is one inspiring person with his accomplishments. A saying that will help me remember Johannes Kepler “My stars were not Mercury rising in the seventh angel in quadrature with Mars, but Copernicus and Tycho Brahe. Without their observation books everything that I have brought into the clearest light would have remained in

Starting in the year 1600, he formulated the laws of planetary motion. In other words, he was the first to realize that the motion of all planets is ruled by the same laws. Kepler then went on to creating 3 laws based on his findings. The first law states that each planet moves around the sun in an ellipse, with the sun at one focus. According to the second law, planets do not revolve around the sun at a uniform speed, but they are faster when closer to the sun, and slower when further from it.

Copernicus Kepler, and Galileo provided the data and the background information and mathematical knowledge to aid Newton in finding and advancing science.9

Johannes Kepler was a German mathematician, astrologer and astronomer. His hard work influenced many others, along with famous scientist, Isaac Newton. Kepler had the chance to work with renowned scientists and use their information to learn and explore more of his own theories. Thanks to Johannes Kepler, we now have three laws to base our knowledge of planetary motion on along with other improvements. Johannes Kepler was born on December 27th, 1571 in Weil der Stadt, Germany.

Johannes Kepler was a German astronomer and mathematician who lived between 1671-1630. Kepler was a Copernican and initially believed that planets should follow perfectly circular orbits (“Johan Kepler” 1). During this time period, Ptolemy’s geocentric theory of the solar system was accepted. Ptolemy’s theory stated that Earth is at the center of the universe and stationary; closest to Earth is the Moon, and beyond it, expanding towards the outside, are Mercury, Venus, and the Sun in a straight line, followed by Mars, Jupiter, Saturn, and the “fixed stars”. The Ptolemaic system explained the numerous observed motions of the planets as having small spherical orbits called epicycles (“Astronomy” 2). Kepler is best known for introducing three
