Johannes Kepler: Three Scientific Theories About The Planet Movements

1536 Words7 Pages

Johannes Kepler Johannes Kepler was a scientist whom introduce three scientific theories about the planetary movements. Planets go around the sun in an oval movement instead of circular movements. He believed that planets move faster while closer to the sun than when they are farers. Kepler introduced mathematical equation relative between a planet's distance from the sun and the time of the time the planet goes around the sun. Kepler published a book called “Kepler’s Laws” in which pointed out some mistakes in the Copernican theory. He opened the door for the future works of a young scientist’s name Isaac Newton which became one of the most important theorist in history. Albrecht von Wallendtein Albrecht Wenzel Eusebius was born September 24, 1583, Bohemia and died February 25, 1634, He was a Bohemian soldier and statesman, commanding general of the armies of the Holy Roman emperor Ferdinand II during the Thirty Years’ War.

Truman in 1947. President Truman said that the United States would go to whatever lengths possible to contain the spread of communism and stop the United States' former ally, the Soviet Union. The doctrine drafted up due to the crises in Greece and Turkey, both, nations were believed were in danger of falling into the Soviet control. The United States and the USSR were alliance during the Second World War, was only to defeat a same enemy the Germans and the Japanese. When the war ended, Stalin became in control of Eastern Europe. The United States realized that Europe and the World were left with two superpowers, and one was as bad as the enemy they just fought and far stronger than before the war. Fear for another war this time between two superpowers, there were mixed feeling and a little bit of guilt. That was the beginning for the cold

Nicolaus Copernicus Accomplishments

624 Words | 3 Pages

Nicolaus Copernicus was an extremely famous and important scientist, astronomer, mathematician, religious figure, and scholar during the 1500’s. He helped shape many of the theories and ideas about the universe that are prevalent in society today. His accomplishments were and still are considered infamous, and although not commonly accepted by people during his lifetime, his development of the heliocentric model of the universe is what we all currently believe to be true. Without his hard work and perseverance on his research, our views of our universe would be very different, and possibly quite incorrect, today. Nicolaus Copernicus was born on February 19th, 1473 in Torun, West Prussia.

Exploiting, mathematics Copernicus was able to create a radically new, post-Ptolemaic system, which illustrated all the celestial objects revolving around the sun. Copernicus also stated that the moon revolved around the earth. Furthermore, this demoted the moon from a planet to a satellite. However, people of his time thought the heliocentric theory was incorrect and strange. Moreover, even Copernicus himself realized that he could not prove his theories merely through astronomical observation.

Comparing Kepler And Cassini

1173 Words | 5 Pages

Before modern technology allowed astronomers to determine the exact distances between the Earth and other objects in the solar system, they had to rely on alternative methods to make these measurements. Two scientists who made some of these early measurements were Johannes Kepler and Giovanni Cassini. Kepler used the time of a planet’s orbit to determine the relative distance between the Earth and other objects, while Cassini used the parallax method to estimate distances. Johannes Kepler was born in 1571 in a small town called Weil der Swadt in Swabia, Germany and is well known for discovering the three laws of planetary motion. In 1589 he began his college level education in Tubingen at the Protestant university there.

Truman presented to congress, an American policy that would limit and contain the communist powers of the world, specifically the USSR(Frazier 3). This plan was originally created for the spread of communist control in Greece and Turkey. The Doctrine was originally supposed to, as Truman stated in his 1947 speech in a congressional joint session, “be primarily through economic and financial aid which is essential to economic stability and orderly political processes. ”(Frazier 12) This piece of legislature was very helpful in the countering of communist power in Eastern Europe.

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.

The Soviet Union began demanding adjustments to its relations and control over Turkey, as well as Iran. Though Stalin backed down at the threat of U.S. Naval forces, his actions led to the containment policy. This policy is used to prevent the spread of communism. Later, in 1947, the United States took over the responsibility of providing economic aid to Turkey and Greece and announced that they would be helping the nations affected by Communism. The Marshall Plan was put into effect later that year and it offered reconstruction aid to much of Europe.

Specifically, the square of the ratio of the period of two plants is equal to the cube of the ratio of their radius. While his first two laws focus on the specifics of a single planet's movement, his third is a comparison between the orbits of two planets with the same sun. Though Kepler is best known for his defining laws regarding planetary motion, he made several other contributions to science. He was the first to determine that refraction causes human, and that having two eyes enables depth perception.

Effects Of The Truman Doctrine

280 Words | 2 Pages

The Truman Doctrine was an American foreign policy to stop Soviet imperialism during the Cold War. It was announced to Congress by President Harry S. Truman on March 12, 1947 when he pledged to contain Soviet threats to Greece and Turkey. No American military force was involved; instead Congress appropriated a free gift of financial aid to support the economies and the militaries of Greece and Turkey. More generally, the Truman doctrine implied American support for other nations threatened by Soviet communism. The Truman Doctrine became the foundation of American foreign policy, and led, in 1949, to the formation of NATO: a full-fledged military alliance that is in effect to this day.

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.

The Cold War began due to this speech, which inspired Western opposition to Soviet expansionism. President Harry S. Truman introduced the Truman Doctrine as a critical strategy for combating the Soviet Union's growing influence over Eastern Europe in 1947. This doctrine was first created to restrict Soviet geopolitical advancements in Greece and Turkey and stated that the U.S. would protect "free peoples who are resisting attempted subjugation by armed minorities or by outside pressures" (Article 4). This approach, which favored containing Soviet power worldwide, quickly became one of the most critical parts of U.S. foreign policy. As the Cold War grew more intense as the 1950s went on, the United States became more committed to restricting the Soviet Union and expanding its power throughout Eastern Europe.

Why Was Kepler's Second Law Important

194 Words | 1 Pages

Kepler's first law is that planets move around the sun in ellipses with the sun at one focus. The second law is the line connecting a sun to a planet sweeps equal areas in equal times. The third law is the square of the orbital period of a planet is proportional to a cube of the mean distance from the sun. The first law is important because it tells us that motion is not uniform circular motion. The second law is important because it tells us that sometimes the plants move quickly and that sometimes the planets move slowly.
