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).
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)
Relying mostly on mathematics, he developed a very different understanding of the universe” (Doc C). Copernicus created the heliocentric model of the universe proving that the sun was the center of the universe. This theory, while not completely correct, has been the foundation of Astronomy and astronomical sciences for
In Chief Tecumseh’s Address to General William Henry Harrison, and Chief Seattle’s Letter to President Pierce, both chiefs attempt to persuade white men in positions of power to leave their tribes alone by explaining their tribes love over the land. In contrast, Chief Tecumseh utilizes allusion to anger his audience into uniting together to stop the white man, while Chief Seattle conveys imagery throughout his speech, stating that the white man will taint the Earth as a result of his greed.
During the Renaissance, astronomy advanced and excelled rapidly thanks to many significant astronomers. Before the Copernican theory was established, Aristotle had a cosmological theory that stated that the Earth was the center of cosmos,
But when the twentieth century was at the gates of new and historical events, that began to change. New discoveries shook the old certainties and paved away for questions about "where the universe came from?". One observation transformed our ideas about the true scale of the universe. It began with a mystery in the sky. By the early part of the twentieth century, it was well known that our solar system lay within a galaxy, the milky way.
He realised that many of the current questions of the universe were successfully answered when a heliocentric worldview was
Energy in the universe gave rise to repulsive gravity which caused it to extend further, this brings us to the concept of the dark energy. According to this concept, the space is extending despite gravity. Physicists proposed that there is a force which contradicts gravity and named it dark energy, due to the fact that it is hidden form the direct detection. In other words, the space has a property which can drive space apart extending it further. (Wolchover)
Edwin Hubble one of the more well known astronomers of his era, was able to provide the understanding and knowledge capable for furthering the knowledge of the universe. Hired in 1919 to work at the Mount Wilson Observatory as one of the more junior astronomers, with the more important questions resulting in along the same lines of 'what 's the nature of the surrounding nebulae. ' It should be noted that Edwin Hubble was able to actually answer this question, explaining that these nebulae or rather some of them were not in the Milky Way galaxy. With the method he used to measure the distances he was able to prove that the universe was actually expanding. Building off the research and discoveries from Harlow Shapley who had measured the distance of the Milky Way, Hubble was able to determine the distance to the nearby Andromeda galaxy.
The big bang theory was proposed by Belgian priest, Georges Lemaître in 1927. He hypothesized that the universe began from a single primordial atom, as is shown by the main circle on the diagram to the left. His model of the big bang is based on two assumptions.
In contrast, the Big Bang Theory has a substantial amount of scientific evidence to back it up. The first piece of scientific evidence for the Big Bang is the Hubble Diagram. The Hubble Diagram is a map of the redshift of the universe. Redshift is when light becomes stretched due to extended galactic travel.
Aristotle had said that the earth was the center of the universe, and no one ever questioned him. Aristotle had also made assumptions in the field of physics and Galileo was the first to go against them. Galileo made many discoveries with his telescope that were significant to science during the Renaissance. To view the solar system, Galileo made a telescope on his own. He had heard of the invention from a Dutch eyeglass maker, and improved his design.
This model added to the advancement of quantum mechanics. c. Reason for listening: This topic is important because people often only think about Einstein’s theory of general relativity, but he offered so much more. d. Credibility: For my informative speech, I have conducted extensive research on the scientific contributions of Albert Einstein. e. Thesis Statement: People view Einstein work as just if he has only contributed a few things to sciences and physics, but he did a greater amount then the majority of people know. Preview of major points: In this speech, I will show you
The Big Bang Theory, known by scientists as for how the world came to fruition,
He understood things many people older than him didn’t even understand. This is important because it shows how much potential and intelligence he had even at a young age that lead him to be so successful. Throughout his growing of age, he gained more knowledge through more studying and investigating during his off time. He began to grow so intelligent that even the most talented and famous scientist could’ve been corrected by him. “Finally, on November 6, the president of the Royal Astronomical Society of England made a public announcement that the photographic plates had confirmed Einstein‘s prediction.
