...Astronomy: Then and Now Have you ever heard the saying you can’t teach an ole dog new tricks? What about the one where three old dogs teach new tricks? I’m sure you have heard that one, anyone who knows about our solar system can thank the three old dogs. Well, they’re not dogs at all, and at their time they weren’t old but in our time their long gone. Of course, I am speaking about Ptolemy, Copernicus, and Kepler. Funny thing is each one of them challenged and changed their predecessor's work, for the better of course, but we will get to that later. We have these three men to thank for a whole lot of new tricks. To name a few would be, our solar system, the way we form our maps, and we can’t forget the numerous mathematical formulas used to make ideas come to life. In this research paper, we will touch base on the lives of three great astronomers and the tricks they have taught us. We will also see how astronomers of today contribute to our everyday lives. Some say that our first astronomer was a great astronomer. Other say, “Ptolemy was the only great astronomer of Roman Alexandria.” (Brown, 2016) It’s all a matter of opinion, but what we cannot deny was Ptolemy was a great astronomer of his time and today. We do not know much about Ptolemy’s personal life. What we do know about him came from his work. He was born around 85ce in Egypt to a Greek family even though he bore a roman name. To say Ptolemy was diverse is an understatement. He was also diverse in his studies...

...Natural sciences study the physical and natural world and the events that occur in nature using scientific methods, and writing in this field is often used to assess your knowledge. The fields within this area of science include, but are not limited to, the following areas: Astronomy, Atmospheric Science, Biology, Chemistry, Earth Science, Environmental Science, Oceanography The most common writing assignments in the natural sciences are case studies, field reports, lab reports and literature reviews. This field is frequently referred to as “hard science” because of the quantitative methods applied and the heavy use of objective data. A great deal of what defines modern civilization are advances in technology and knowledge gained by investigations in the natural sciences. Statistics and mathematics provide the framework for this field, where quantifiable data and accuracy are essential components. The main goal of the natural science essay is to utilize problem-solving techniques that report results through analysis and observation. Expectations for writing in the natural sciences Whatever your topic when writing in the natural sciences, make sure you understand the assignment before you start.

...to report to a central location and receive their education at that location. Learning can be difficult in adult education programs when students and educators have employment outside the classroom. For traditional students, interactive learning can supplement classroom learning. Interactive learning utilizes computer software programs to assist students and teachers with lessons, according to HR dictionary. This software allows instructors to assign material for upcoming class discussions, receive assignments, and provide feedback to students. Controlling The Content Students can review course content at their own pace with interactive learning, By working at their own pace, students may prepare for other activities outside of school coursework. It also allows students to move quickly through material they understand, and then slow down for material that is more challenging for them personally. By using interactive learning, students are not delayed byother student's questions. Teachers can add new material to an interactive learning environment when each student is ready for it. Reducing Expenses Interactive learning can reduce the costs of operating a classroom. Educational institutions can save money on rent and lower their utility bills since interactive learning eliminates the need to be in a classroom all the time. This also allows the institution to use their space for classes that can not be taught in an online interactive environment. For teachers and students...

...does. It just seems to be human nature to ask such questions and to try to discover more about the complexity of human actions and causes. Of course, there are many perspectives in the field of psychology that attempt to address these significant questions. For instance, biopsychology considers important factors including one’s brain, genetic predisposition, and many others when addressing behavior. However, social psychology, even though it agrees with other branches in psychology, does focus on different aspects when seeking these kinds of conclusions. Social psychology centers their attention on understanding human actions such as what led to the cruelty of killing millions of people during War II. Why will one always help him or herself first, before helping others? Why do others matter more when making decisions? Social psychology is essential not only to the field of psychology but also to every individual because it provides answers to questions one seeks about him or herself and others. However, social psychology does more than provide answers to these few questions, as these merely touch the surface of social psychology’s focus (Myers, 2010). Definition of Social Psychology Social psychology is a science just like many other fields including astronomy, psychology, biology, sociology, and psychology. A much clearer distinction can be made however, when they are further divided. For instance, astronomy and biology are parts of natural science whereas sociology...

...ASTR 122 05/13/2013 Assignment #3 951131748 WangJae Lee Astronomy 122 Distance Education Third Homework Assignment 1. Explain why measuring parallax distances for only the brightest appearing stars in the sky would give you a biased luminosity scale and an unrepresentative sample of stars. -The stellar parallax measures the relative distances from stars to different positions of the Earth in order to measure luminosity. It is done by using distant stars as a fixed reference system so that if a star is observed in respect to the distant stars today, and then measured again in six months, a small shift in movement will be recorded. It is absolutely necessary for there to be “distant stars” or less bright stars as a frame of reference otherwise the angle measurements would have nothing to compare against. Thus, it creates a biased scale of recorded luminosity. 2. Explain the overall concept of pressure support (against gravity) in stars and why stars are unstable if they are not generating energy in their cores. -The concept of pressure support can be explained through the internal gas pressure. The internal gas pressure is attempting to expand and dissipate our ball of gas, while the self-gravity of the gas (due to its mass) is trying to collapse the ball. As the gas gets hotter, the internal gas pressure increases. Then, it reaches a point of stabilization between gravity and pressure support. -Stars are unstable if they are not generating energy in their cores because...

...Transcript Akeem Saunders Kaplan University HU300 Arts and Humanities Laurie Smart-Pottle 21st September, 2013 What Does Happiness Mean? The first person I choose to interview is Ms. J.Roker. She is between the ages of 30- 40 years-old and is a volunteer at the Exuma Land and Sea Park here in the Bahamas. She loves working for non-profit organizations especially those which gives back to the community and protects the environment. She has been a foreign volunteer for two years. Being enlisted in the military I am required to be deploy to various sub bases within and without the Commonwealth of The Bahamas. Thus, my interview took place on Walderick Wells, a Cay located in the Exuma Land and Sea Park. I had known Ms. Roker, little under two weeks and was intrigue as to why she choose the Bahamas to work instead of America. Every morning she would open the park office and we would start a casual conservation. Her views on life were astounding and to see how her dog Grace interacts with her is just amazing. She always seemed very happy whenever I saw her and always was giving. When I think of what happiness looks like I always think of her. My second choice is Mr. D Bonaby. He is between the ages of 40-50 years and is an active member in the military. He has been deployed to the same sub base as me and he has been my superior for the past 10 years. He is a welder in the military and hopes to open his welding business when he retires from...
