Johannes Kepler's Accomplishments

1346 Words6 Pages

Johannes Kepler was an extremely passionate and enthusiastic young astronomer who was entirely captivated by the centrality of the sun in the heliocentric theory and also the mathematical harmonies of the world – direct relationships between numbers and natural properties. Among his other slightly ridiculous discoveries, Kepler discovered three unequivocally important laws of planetary motion that began to fill out the framework of the heliocentric universe and allowed the paths of the planets to finally be mapped correctly. Kepler’s first law states that planets travel in ellipses rather than perfect circles, his second law concludes that planets travel faster as they near the sun and slower as they move away from it, and his third law is …show more content…

Galileo made extensive contributions to a number of fields including physics, astronomy, and mathematics. Obsessed with studying different types of motion and paths of falling bodies, Galileo used the pendulum to keep time as accurately as possible while performing various simple experiments such as rolling balls of different weights down inclines with specific angles. All of these exercises allowed Galileo to establish a practical understanding of motion and mechanics that would later be used by Isaac Newton (Kreis, “Lecture 11”). However, one of Galileo’s most impressive feats was his invention of a telescope powerful enough to reveal details and imperfections within the heavens never seen before. Galileo was the first person to see things such as moon craters and sunspots. He was also the first to detect and give accounts of the rings of Saturn, the phases of Venus, and Jupiter’s moons, all contained in his book, The Starry Messenger. Unfortunately, Galileo’s advocacy of and great confidence in his discoveries, along with his belief that they did not actually contradict the teachings of the Bible and the Catholic Church, put him in the direct path of the Italian Inquisition, members of which did not share his sentiments. Forced to recant under the threat of torture, Galileo spent the last eight years of his life under house arrest (Kreis, “Lecture

Johannes Kepler was a German astronomer, mathematician and theologist. Kepler was born in Weil der Stadt, near to Stuttgart, in 1571. Johannes Kepler is nowadays most famous for developing the three laws of planetary motion in the early 17th century. Johannes Kepler’s family was a very poor family, his father left him when he was only five, and because he was prematurely born, he was a very weak child and was ill a lot. These were not optimal circumstances for someone, who made it very far in his later life and resisted all of the negative conditions.

How Does Galileo Discover The Moons Of Jupiter

Galileo Discovers the Moons of Jupiter (1610) Galileo Galilei Introduction Galileo Galilei, (1564-1642) the gifted and extremely curious Italian scientist, made great use of the telescope to discover such unsettling things as the irregularities of the moon's surface; it was believed at the time to be perfectly smooth, a belief which conformed to Catholic dogma. Moreover, Galileo's observations with the telescope led him to the conclusion that Nicolas Copernicus (1473-1543) was right: the earth did indeed orbit around the sun and not vice versa. Such a viewpoint cast great doubt on the accepted natural philosophy (first enunciated by Aristotle) of a geocentric universe and thus of human beings' centrality in the universe. Thus the conflict between religion and science in the seventeenth century was begun.

Kepler's third law states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit. Discovery of supernova: In 1604, Kepler observed a supernova (SN 1604) in the Milky Way. He wrote a book about his observations, which helped to advance the understanding of supernovae. Astronomical tables: Kepler created astronomical tables that were used by astronomers for many years. These tables helped to improve the accuracy of astronomical

Many scientists thought that planets would travel in circles around the earth, but not Kepler, he believed that planets orbited the sun, and not the earth, he additionally uncovered that their paths were imperfect circles. The infrequent issue was tackled by the expansion of smaller than expected circles test — epicycles — to planetary ways. Johannes Kepler made many accomplishments, but one that is really important in today’s society, are the eyeglasses, Kepler invented the the lenses of the glasses.

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.

In the beginning of the 17th century a man named Johannes Kepler published three laws of planetary motion for a sun centered solar system. These three laws became known as Keplars three laws, and where based off of the data that was gradually collected by his teacher and mentor Tycho Brahe. The reasoning behind the explanations for these laws are no longer accepted as accurate, however the laws themselves are considered as a good description for the motion of any satellite and are still used even today. Keplars first law is sometimes known as the Law of Ellipses, this law explains that planets orbiting the sun are not orbiting in a circular path but instead in an elliptical path.

Although Kepler is remembered today chiefly for his three laws of planetary motion, these were but three elements in his much broader search for cosmic harmonies and a celestial physics. With the exception of Rheticus, Kepler became the first enthusiastic Copernican after Copernicus himself; he found an astronomy whose clumsy geocentric or heliostatic planetary mechanisms typically erred by several degrees and he left it with a unified and physically motivated heliocentric system nearly 100 times more accurate. When Kepler was twenty-five and much occupied with astrology, he compared the members of his family with their horoscopes. His grandfather Sebald, mayor of Weil in 1571, when Kepler was born, was “quick-tempered and obstinate.” His grandmother was “clever, deceitful, blazing with hatred, the queen of busybodies.”

Task 1 Part A In 1599 Tycho Brahe, a Danish astronomer, had called for Johannes Kepler, a clever mathematician, to become his assistant. Kepler embraced the heliocentric model of the universe and created a desire to prove it mathematically. When Brahe died in 1601, Kepler inherited his work and data on the motion on planets. Kepler worked for many years, using Brahe’s data and Copernicus’s ideas, how planets move about the sun, and he eventually produced an improved heliocentric model of the universe.

Johanness Kepler is a key figure during the seventeenth century. He believed in his theory of the geometrical relationship between the orbits of the planets. And later on, I learned that his attempts to explain the planetary motions into five perfect solid shapes failed. It was the data of Tycho Brahe, a Danish nobleman and astronomer, which helped Kepler discover the three major laws of planetary motion. These data were accurate and broad astronomical and planetary observations that support his predictions that the planetary orbits were ellipse rather than his former guess- circle and the planets move with the Sun at one focus.
