Astronomy Informative Speech

Have you ever been to a trampoline jump park?Well I have and I will tell you how it all started when they took down a Halloween store to put up the new Sky Zone that is right beside Home Depot and when it was open I asked my mom if me and my sister Giselle can go to Sky Zone but my mom said “no you can’t go to Sky Zone but you and Giselle can go next week because it is Sunday to day’’ so me and my sister what and what tell next Saturday.When it was Saturday me and my sister Giselle we're happy to go to the new Sky Zone and that Saturday morning me my mom and my sister woke up and me and my mom cook breakfast whale Giselle was on her phone talking to her friend about going to the new Sky Zone but meanwhile me and my mom was finished with the

He found that one single force, called gravity, kept all of the planets in their orbit around the sun. One day, as an apple fell from a tree to the ground, Isaac Newton wondered if the same force that made the apple fall to Earth, had anything to do with the movements of the planets.Through mathematics, over the next 20 years, he refined his new theory. Isaac Newton even published a book explaining gravity, along with other things about the universe. He says uniform laws are followed by nature, and that all of the motion the the entire universe can be described and measured mathematically. Throughout his life, he discovered three laws of motion, and titled them Newton’s Three Laws of Motion. The first law is the Law of Inertia. This basically states that an object in motion, will retain its state of motion. The second law is force equals mass times acceleration. So, the more mass to an object, more force is needed to accelerate it. Finally, the third law states that for every action, there is an equal and opposite reaction. This means that when you push an object, it pushed back equally as hard in the opposite direction. In conclusion, Isaac Newton still impacts us today because we still use all of his laws, and he also partly discovered a branch of mathematics called calculus, in which we still use

Ptolemy, a Roman astronomer came up with the theory that the universe revolved around Earth and all the creatures inhabiting it (Doc. C). This theory, The Geocentric Universe of Ptolemy, was adjusted by most of the people during The Middle Ages. However, much later on, Nicolaus Copernicus, a Polish astronomer, disagreed with Ptolemy’s theory. With his use of math and reason, he came up with a new theory called The Heliocentric Universe of Copernicus (Doc. C). He said that the universe & Earth itself revolves around the sun. The Church denied this theory because they did not want to be proven wrong. If the Church was wrong about this part of the universe, this would then cause man to wonder what else they could be wrong about, or even lied to them about. This new theory taught men to think for themselves and not to rely on the Church for

Aristotle’s model by today’s standards can easily be picked apart, but at the time, it was the best explanation that could be made with so little technology and insight. Although his theories have long since been replaced, they created a base for future scientists to work off of and challenge. Over time many great scientists began to question Aristotle’s theories. Nicolaus Copernicus (1473-1543), for example, contested the absolute significance of the earth, and he did not agree that it should be viewed as the center of the entire universe (Lizhi & Youquan, 1987). He plotted the earth at the center of the universe and created a heliocentric system just as mathematically complicated as the Ptolemaic system (one that also improved on Aristotle’s), but it explained a number of anomalies, including resolving the issue of retrograde motion (Ede, A. & Cormack, L., 2004). The problem was that Aristotle’s physics of ‘natural motion’ fell apart without the earth in the center of everything.

So when Copernicus brought up the idea of the heliocentric earth it came in conflict with the Church. In Document C it sates "Ptolemy... developed a theory of the universe that was adopted by most scholars during the

Anybody can tell just by looking at the diagrams of the solar system from the two different time periods that there was a big gap in between the thoughts of the two men who made them. Ptolemy, the man who made it in the medieval period, made people believe that the earth was in the center of our solar system, and the sun was the third planet from the earth. He also made people believe that, “the outer sphere… the Empire of Heaven and Home of God and the Elect” (DBQ Online Document C). These facts were not only untrue, but they also caused everyone to believe that this was correct.

Copernicus published "On the Revolutions of the Celestial Spheres" in 1543 , sparking off the scientific revolution and a new era of astronomical thought. This theory explains that the sun, not the Earth, is the center of the solar system and planets move in a circular motion around it. This had many social, intellectual and religious made of huis idea. For instance, this theory brought into question the strict reading of the Bible and philosophies of the Catholic Church.

From the time of Aristotle up until the time of Newton there were five models of what humans thought of the universe. The astronomers who developed these models were Aristotle, Ptolemy, Copernicus, Tycho Brahe, Kepler, Galileo and Newton.

1) Modern astronomy basically begins with the re-emergence of the heliocentric view of the universe by Copernicus.   Who were the four other major contributors to the development of modern astronomy after Copernicus?  Explain what those contributions were.  Finally, why did it take so long for the geocentric view of the universe to be overthrown and what does that tell us about scientific research and our society, even today?

Newton’s first law, often called the law of inertia, says that a moving object will continue moving in a straight line at a constant speed, and a stationary object will remain at rest unless pushed. This means that all objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion (the hockey puck) will maintain this state of motion. Newton’s second law says the acceleration produced on a body by a force is proportional to the magnitude of the force and inversely proportional to the mass of the object. In simpler terms, this means the greater the force, the greater the acceleration; but the more massive the object being acted on by a given force, the smaller the acceleration. Newton’s third law says that or every action there is an opposite reaction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.

The first theory of the placement of the planets and stars to disprove the theocentric theory, God centered, was the geocentric theory. This idea began with the philosopher Aristotle in fourth century B.C. Greece, and was expanded and better explained in second century A.D. by Greek Astronomer Ptolemy. The main point of this theory was that the Earth was the center of the universe. This was “proven” by the observation of the sun moving around the earth every day, as seen in the

Throughout time people have held different ideas of what the universe looks like, from the Aristotelian universe centered around the Earth to the Copernican universe with our Sun at the center. After Sir Isaac Newton invented physics,

We are Stargazing in 35mm, a Seattle area genre-fluid space rock band. Our sound is very diverse, and we can alter our set list to fit well with almost any band. We are still new to the music scene, but we drew about 40 people at the Northwest Folklife Festival and about the same amount at our album release party. We have played at auctions, farmers markets, graduations, battle of the bands and some small local venues. We would be very interested in opening for local or passing though bands.

Everybody has heard of the name Vincent Van Gogh. Maybe you’ve heard about his ear or you’ve seen his painting “The Starry Night”. Perhaps you had seen one of his paintings but didn’t know who he was. I am happy to tell you: today is your lucky day. You will be learning a little about him. He was a Dutch painter which was one of the 4 artists who led the movement Post-Impressionism (the use vivid colors, thick application of paint, and real-life subject matter), Van Gogh made about 2,100 artworks, including around 860 paintings. He didn’t have a good life. Van Gogh was constantly depressed, got heartbroken multiple times in his life (he never got married), and was insane. He suffered from psychotic episodes and hallucinations. Often, he didn’t care and neglected he was mentally unstable. For this reason, he did not eat properly and drank a lot.

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
