Nicolaus Copernicus :: Essays Papers

Nicolaus Copernicus The sixteenth and seventeenth centuries were known as the Scientific Revolution. During these centuries, science was starting to answer many questions about the earth. Scientists all around the world were making their assumptions on how the universe worked. Nicolaus Copernicus was a Polish astronomer that also had a theory. The Copernican Theory changed many views and had a great effect on society. Copernicus lived his life in Poland. When he was nineteen, he decided to study at the University of Cracow. At the university he was required to study grammar, rhetoric and logic, arithmetic, geometry, music and astrology or astronomy. Edward Rosen is the author of, Copernicus and the Scientific Revolution. He says, "The subjects offered during his years there are known form university records that are still preserved. The names of the professors who taught those courses are also known. But the students’ records are missing."1 The grades that he received in college are unknown. However, it is known that he did not stay long enough to earn a bachelor’s degree.2 After Copernicus left school he returned home to his uncle, Lucas Waczendrode, who was the bishop of Ermeland.3 His uncle suggested that he enter the canonry n Frauenburg. The canonry is a group of clergymen that belong to a cathedral or other church. Entering the canonry would give Copernicus a stable and secure income for the rest of his life. While he waited for an opening, his uncle sent him for training at the University of Bologna.4 While there he studied mathematics and Greek language for three and half years. He also became more familiar with astronomy. In 1501 Copernicus returned to Frauenburg where he became apart of the canonry. He left quickly and started to study in Italy at the University of Padua. There he studied law and medicine.5 After a lifetime of studying, he is said to have mastered the concepts of math, medicine, theology and astronomy.6 As Copernicus began to study astronomy more, he came to strongly disagree with the Ptolemaic system of astronomy. This system was based on the idea that the earth was fixed in the center and all the other heavenly bodies moved around it. Astronomers believed that the earth was in the center because it was heavy. Copernicus saw many problems associated with this system of astronomy. For example, sometimes the planets appeared to be going in the opposite direction and the brightness of the planets would tend to change as well.

Using the documents, analyze Han and Roman attitudes toward technology. Identify one additional type of document and explain briefly how it would help your analysis. The Han and Roman Empires were extremely important empires during the time of their existence. The Han Empire began around 206 BCE and ended at around 220 CE. The Roman Empire began at around 27 BCE and broke apart into two halves, the West falling in 476 and the East collapsing in 1453. The Han Dynasty and the Roman Empire have different outlooks on technology, the Han Dynasty view technology as a practical application used to ease the workload of people, while the Roman Empire views certain technology as needed, despite the creator. The Han Dynasty viewed technology as a way to ease the workload. A Han government official proposes a possible technological solution to prevent floods. His ideas include people to watch over the machinery used to ease the workload of people preventing floods. Huan Guan, in h is Discourses on Salt and Iron, says that in previous times, people had the liberty to do foundry work and salt-boiling, but had to pay a tax. He says that the tools to do this work used to be well-made, but in current times the tools are made by convicts, and are crude and not very functional. Due to the high price of these crude tools, which do not do much to ease the workload, many people have become poor, and are forced to rely on wooden tools, and cannot afford salt. Huan Tan, in his New Discourses, says that Fuxi, a mythological emperor, created mortar and pestle. he also says that, over time, other things were used and upgrades were made in order to increase the benefit and decrease the workload hundredfold. The government-sponsored History of the Early Han Dynasty claims that Tu Shih loved the common people and wished to save them labor, so he invented a water-powered-blowing-engine. This saved them time, and effort. The Roman Empire viewed some technology as important, d espite the creator. Cicero, in his On Duty, says that craftsman who are hired for labor, and not skill, are vulgar. Despite who it is, it is a loss or decline In technology and skill in exchange for increased labor. . Plutarch says that Gaius Gracchus built needed roads, and mile-calculating systems. These were needed technological advancements, and despite the creator, they were useful. Seneca says that the hammer and tongs were not created by wise men, nor does it matter which came first. He says that they were created by someone nimble and sharp, and are useful. Frontinus says that the aqueducts are important, and are very useful. He then goes on to say that the pyramids and the useless but famous works of the Greeks are unimportant, for they do not help the empire. Documents that would help to further my analysis of these subjects would be a document from a Han and Roman common-person on the benefits of technology. This would help me to better understand the effects of tec hnology on their lives, and how it has helped society. It would also help to show the usefulness of their technology. The Han and Roman Empires are very important. They have greatly influenced the past, and many other societies worldwide. The Han Dynasty and the Roman Empire have different outlooks on technology, the Han Dynasty view technology as a practical application used to ease the workload of people, while the Roman Empire views certain technology as needed, despite the creator. If not for the technology and the technological views of the Han and Roman Empires, the world would be a much different place than what it is today. Don’t waste time!

Death Penalty - 1382 Words

In all societies, many cases occur where a criminal must be punished, so that they can be taught a lesson, and they can stop committing crimes. There are many different ways of punishing criminals: one is the death penalty. The issue of the death penalty has been avidly discussed throughout history. Some people support the idea of the death penalty, since they say it is only fair for one to forfeit their life if they take the life of another. Others feel that the death penalty is not fair, and fear that many innocents have been penalized for something they did not do. The issue of capital punishment deals with the moral issues of many people with different opinions within a community. It is a cruel punishment, and many have stated that†¦show more content†¦Interaction with others is kept to a minimum. Perhaps this kind of treatment might be punishment enough. Many consider the ultimate form of punishment as no disincentive for the crime of murder, and feel it increases killing, rather than diminishes it. They also hold it to be morally wrong. There are many difficult issues to deal with after a death sentence, which puts the family of the convicted person into as much discomfort and strife as the sentenced person. The most horrifying part is that they are constantly reminded of what will happen. The horrors of execution, the preparation for it, the psychological infliction of pain and the actual means of execution are considered by many to be barbaric. A whole sector of the community feels that it is an evil act to have any person put into that circumstance. â€Å"In criminal justice, combining this kind of ritualism with killing is considered an aggravation of murder. Yet this is the kind of death the state imposes on those it executes. (Black 1998)† To punish evil with evil, the writer continues, and to exact an eye for an eye, and measure for measure, is to become as callous as the criminals.

Advantage is gained by moving the operator away from the load Class room Teachings by Manoj Tiwari 6 Fixed Pulley†¦ †¢A fixed pulley does not ncrease your force and therefore gives you no advantage. †¢It helps a person lift things by changing the direction of force. It allows a person to pull down in order to lift a load up. Class room Teachings by Manoj Tiwari 7 Fixed Pulley†¦ Class room Teachings by Manoj Tiwari 8 Movable pulley (Floating Pulley)†¦ Used to gain mechanical advantage to lift weight (W) by multiplying the forces Weight of force (F) requi red to move the object is equal to the number of ropes (N) supporting the load (W). F = W/N Class room Teachings by Manoj Tiwari 9 Movable Pulley†¦ It is called a movable ulley because it moves with the load. The pulley is suspended by a rope with one portion of the rope (called a rope segment) on each side. Each rope segment supports half the load. Class room Teachings by Manoj Tiwari 10 Movable Pulley†¦ The pulley is suspended and as a consequence the mechanical advantage is increased. The rope on the left and right of the pulley are both lifting the LOAD, they each lift half its weight hence the load is split into 2 parts. Class room Teachings by Manoj Tiwari 11 Combination Pulley†¦ †¢The problem with movable pulleys is that a person has to pull up to lift a load. In order to make the job of lifting a load easier, a fixed pulley can be added to allow lifting a load by pulling down. †¢By combining a fixed pulley to a movable pulley, a person gets the advan tages of both. The movable pulley doubles the person’s force, and at the same time the fixed pulley let the person pull down to lift the load up.

Comparing themes in Recitatif and This is What It Means to Say, Phoenix, Arizona free essay sample

The relationships we see within Toni Morrison’s â€Å"Recitatif† and Sherman Alexie’s â€Å"This is What it Means to Say Phoenix, Arizona† are very complex, however, whether we’re examining a mother and daughter, or two childhood friends, it is clear our theme deals with the security and solidarity of relationships. Toni Morrison’s â€Å"Recitatif† depicts the complex relationships that two girls in foster care, Twyla and Roberta, have with their mothers. Twyla’s mother and Roberta’s mother share a tragic flaw their conditions prevent them from caring for their daughters. However, their conditions do differ Twyla’s mother’s condition may be self inflicted. Twyla’s mother is a prostitute, and she may drink or do drugs heavily in the way that we see her sloppily greet Twyla: â€Å" and she smiled and waved like she was a little girl looking for her mother not me. † (Morrison 370) â€Å"Mary dropped to her knees and grabbed me, mashing the basket, the jelly beans, and the grass into her ratty fur jacket. † (Morrison 370) Roberta’s mother may suffer from conditions out of her control she seems as though she is mentally ill. Roberta’s mother obsessively holds her Bible and refuses to shake Twyla’s mother’s hand. We can also note that these conditions never cease each time Twyla and Roberta’s lives intersect, they mention that their mothers never got better: â€Å"Did I tell you, my mother, she never did stop dancing. † (Morrison 370) The relationships Twyla and Roberta maintain with their mothers can be seen as dysfunctional solely on the fact that the girls are in a foster home. However, the mothers’ visit at St. Bonny’s gave me a slightly different feeling these dysfunctional mothers love their daughters very much, in very different ways. While Mary’s sloppy entrance mortified Twyla, their embrace is a very secure, happy moment for Twyla: â€Å"I could have killed her†¦ But I couldn’t stay mad at Mary while she was smiling and hugging me and smelling of Lady Esther dusting powder. I wanted to stay buried in her fur all day. † (Morrison 370) We can see Roberta’s loving relationship with her mother during the same visit at St. Bonny’s: â€Å"Her mother had brought chicken legs and ham sandwiches and oranges and a whole box of chocolate-covered grahams. Roberta drank milk from a thermos while her mother read the Bible to her. † (Morrison 370) This loving dynamic almost made me forget that Roberta was living as a foster child. I tried to ignore that Roberta’s mother may have gone the extra mile out of guilt or compensation Roberta was happy, and was too young to analyze the gesture further anyway. In Sherman Alexie’s â€Å"This is What It Means to Say Phoenix, Arizona†, we analyze the relationship between Victor and Thomas. Victor and Thomas were friends in their early childhood, but had a falling out at fifteen years old. The falling out was a drunken fist fight initiated by Victor, leaving Thomas badly beaten up. We might believe that Victor acted aggressively towards him out of embarrassment he wanted to show the boys in their neighborhood that he wasn’t friends with Thomas, because Thomas was an outcast: â€Å"All the other Indian boys stood around and watched it happen. Junior was there and so were Lester, Seymour, and a lot of others. † (Alexie 326) We might also credit their falling out to the fact that they have such different cultural beliefs. Thomas is extremely unique he tells odd stories, and believes nature can speak to him: I heard it on the wind. I heard it from the birds. I felt it in the sunlight. (Alexie 326) While those may seem like characteristics of a mental patient, Thomas takes his beliefs from a traditional Native American culture. Victor’s cultural beliefs stray from that lifestyle, and eventually led him off of their reservation. We see how different their beliefs are during their conversation on the Fourth of July: â€Å"‘You know’ Thomas said. ‘It’s strange how us Indians celebrate the Fourth of July. It ain’t like it was our independence everybody was fighting for. ’ ‘You think about things too much,’ Victor said. ‘It’s just supposed to be fun. ’† (Alexie 326) In their short interaction, it is clear that Thomas has an identity that is more aligned with the Native Americans who were put onto reservations and do not feel American in the cultural sense of the word. Thomas doesn’t feel that the Fourth of July applies to him. Victor, on the other hand, is simply enjoying the excitement of the fireworks, fun, and celebration. Victor doesn’t put much stock into the thought that Native Americans do not have their freedom in the way the Fourth of July presents it. The two stories represent a similar theme: the influence of our relationships as we mature into adults. Twyla and Roberta’s relationship influences they way they interact with each other as adults. While Victor didn’t have much of a relationship with his father, the trip he takes to retrieve his father’s remains becomes an emotional journey. We can also compare these stories in their use of flashbacks and flashforwards which are explained by Jan Schmidt in our Legacies textbook. Flashbacks and flashforwards provide â€Å"dramatic impact, irony and double meanings† (Schmidt 1346)
