Dissection and graded - Assignment Example A progressive disorder can be dealt with if proper genetic testing is done, but at times unpreventable diseases are found out by genetic testing. In these cases there are ethical issues which may arise. An example of an ethical issue arising due to genetic testing is the chance of someone using a person’s personal information against someone which could prove to be harmful. Hence it can be clearly stated that genetic testing is a matter of privacy and individual choice. Laws passed by HIPAA and GINA protect personal information of those being tested and eradicate the chances of discrimination (Norrgard, 2008). 1. You are an epidemiologist at a county hospital. The hospital has asked you to examine the effects of antibiotics administered to patients before surgery that involves opening of the chest cavity. The time frame for administration of antibiotics to patients before surgery is 2-hour intervals for up to 24 hours. The overall objective of the study is to reduce surgical infections and deaths associated with surgery. The hospital administration has given you 15 years to complete the study. The purpose of administering antibiotics prophylactically is important prior to any surgery. The main need for this administration is to prevent any possible post-surgery infections. The possible wound infections result in extended stays of patients at hospitals. These infections develop due to microbial virulence factors, local factors, surgical techniques and systemic factors. Over the years epidemiologists at the hospital facility worked to choose the best suitable antibiotic. The antibiotic had low toxicity and low chances of allergies. The antibiotic of choice was given 30 minutes before the surgery. The concentration of the drug given was adjusted with the duration of surgery. In surgeries which involved incising the chest cavity, the antibiotic of choice was cefazolin (Holzheimer, 2001). A comparative study was carried out between the efficacies of two

Conquerors or Jinas Essay Example for Free

Conquerors or Jinas Essay Jainism originated in ancient East India by the birth and ultimate liberation of twenty four conquerors or Jinas. People of the Jain faith believe that Jinas are human beings who become divine by subduing their sensual desires and overcoming karma, which is the accumulation of good and bad deeds. Good deeds allow living beings to be reincarnated into superior forms, while bad deeds force them to accept inferior forms after death (â€Å"Jainism†). The Jains believe that the first Jina or conqueror was a giant living on earth 8. 4 million years ago. The last Jina was Mahavira or The Great Hero, born in 550 BC. Mahavira is known as the founder of Jainism, seeing that he was able to attract a large number of followers to his faith (â€Å"Jain Dharma†). Like Siddharta Buddha, Mahavira had belonged to the warrior caste and â€Å"renounced the world† at the age of thirty (â€Å"History of Jainism†). Also like the Buddha, Mahavira had sought spiritual reality in the solitude of asceticism. Ultimately he had found enlightenment, although it had taken him thirteen long years to get there. He had converted eleven Brahmans to his faith soon after. By the time of his death, he had founded a community of ascetics with fourteen thousand monks and thirty six thousand nuns. Mahavira is further known to have starved himself to death – a practice referred to as salekhana (â€Å"History of Jainism†). According to the Jains, Mahavira is one of the fortunate ones, as he has â€Å"conquered love and hate, pleasure and pain, attachment and aversion, and has thereby freed ‘his’ soul from the karmas obscuring knowledge, perception, truth, and ability (â€Å"Jain Dharma†). † The first and foremost principle of living taught by Jainism is called Ahimsa or non-violence toward all living beings. Thus, the followers of Jainism have never encountered a problem of violence in their history. The only issue that the people of the Jain faith have had to confront is disunity. Two hundred years after the attainment of nirvana on the part of Mahavira, the Jain faith was divided into two sects: the Digambar and the Svetambar. Both sects hold different views or beliefs about a number of issues. For example, Digambar monks of the Jain faith do not wear anything because of their belief that clothes serve as reminders of the world. Svetambar monks, on the other hand, are known to wear seamless clothes that are usually colored white. Moreover, the Digambars are of the opinion that women are unable to attain liberation while they are living as women on earth. Svetambars, on the contrary, believe that women may indeed achieve liberation seeing that one of the Jinas was a woman. Likewise, the Digambars and Svetambars have varied views about the prayers that are traditionally recited by the Jains (â€Å"Jainism†). The Jains do not believe in a creator of the universe. According to them, the world is without beginning or end. Furthermore, there is no single god of the universe (Sivananda). The following is a prayer of the Jains describing their unique concept of divinity, following by a brief introduction of the same: I bow to the Arahants, the perfected human beings, Godmen. I bow to the Siddhas, liberated bodiless souls, God. I bow to the Acharyas, the masters and heads of congregations. I bow to the Upadhyayas, the spiritual teachers. I bow to the spiritual practitioners in the universe, Sadhus. This fivefold obeisance mantra destroys all sins and obstacles, and of all auspicious repetitions, is the first and foremost (Welcome to Jainism. org). Jains believe that all living beings are the same essential soul, but those human beings that perfect or liberate themselves are turned into gods. These souls – part of the single soul of all living beings, albeit separate – are worshipped by the Jains. Furthermore, these souls are the only ones that do not have to deal with karma any longer. They have achieved salvation through enlightenment, abandonment of worldly attachments, and asceticism. By controlling their selfish desires, they have followed their spiritual teachers to the core. For them, Jainism is the only true religion. Additionally, by attaining the divine status, they have become omnipotent and omnipresent (Sivananda). Before becoming gods, the liberated souls were able to achieve death at will. On the other hand are souls that are so attached to life that they do not wish to end their lives on earth. Such souls die nevertheless. Their death is Akama Marana, the death of helplessness, leading the soul to return to earth in an inferior form (â€Å"Death in Jainism†). There are seventeen kinds of deaths in the Jain faith: â€Å"Avici-marana; Avadhimarana; Atyantika-marana; Vasarta-marana; Valana-marana; Antahsalya-marana; Tadhava-marana; Akama marana; Pandita-marana; Balpandita-marana; Chadmastha-marana; Kevali-marana; Vaihayasa-marana; Guddhapristha-marana; Bhaktapratyakhyana-marana; Inginta-marana; and Padopagamana-marana (â€Å"Death in Jainism†). † Unsurprisingly, all of these separate types of deaths lead to a different kind of life after death. Jains are believers in the reincarnation of all living beings. Thus, the soul that dies the Pandita-marana death is said to have left the earth in peace and with satisfaction (â€Å"Death in Jainism†). The best kind of death is, of course, the very last one, that is, the end that leads to ultimate liberation from the process of rebirth (â€Å"Jainism†). Besides Ahimsa or non-violence, which forbids actions that cause verbal, emotional or physical harm to living beings; the principles of human behavior that the Jains must adhere to include the principle of Satya or the command to speak the truth and avoid falsehood; Asteya, or the command not to steal; Brahmacharya, or the principle demanding all Jains to remain monogamous in their sexual relationships; and Aparigraha, which is the principle of detaching oneself from the world by a reduction of worldly desires and abstinence from hoarding of material wealth (â€Å"Jain Dharma†). The Jains do not convert people to their faith. Hence, anybody who is willing to follow the faith of Jainism must believe in these moral principles and follow them without compulsion (â€Å"Jainism†). Jains additionally believe that every living being has the potential to attain ultimate liberation from the cycle of rebirth. The perfect and liberated souls serve as models on the path of attaining liberation. However, all living beings are responsible for their individual good or bad actions (â€Å"Jainism†). In order to attain ultimate salvation, souls must also believe in the triple jewels, that is, â€Å"[r]ight faith, right knowledge and right conduct (Sivananda). † Right faith constitutes belief in the perfect and liberated souls as real gods, the Jaina Sastras (written by spiritual teachers) as the scriptures of the Jain faith, and the saints of Jainism as the real teachers. Right knowledge provides the follower of Jainism with an eye of certainty that sheds all doubts. Right conduct, of course, constitutes the five moral principles that all Jains must adhere to, including Ahimsa, which compels all Jains to live as vegetarians (Sivananda). Lastly, Jains believe in overcoming all biases and prejudices, and gathering the viewpoints of others, despite the fact that the followers of the faith are divided into sects (â€Å"Jainism†).

Educational Games Essay -- Media, Radio, Television

Media has been shaping our society since the era of print. Print gave way to radio, and radio to television. Now, television is giving way to a new medium, video games. Video games control a market that rivals big movie production, and draws the attention of billions around the world. Can this new media be harnessed for the betterment of education? Videogames are having a positive effect in today’s classroom. Case studies of educational games show, student test scores are improving, students are receiving constant and immediate feed-back, and students are expecting to use technology in school. Society is fascinated with new technology, and it would be negligent not to use the latest technological means to educate our future generations. Case studies to determine the effectiveness of education video games have been conducted at all academic levels. David McDivitt, a history teacher at Oak Hill High school in Indiana, conducted a study of the game â€Å"Making history.† He used his own history class; 110 students across five classes. Three classes totaling 65 students played Making History, and two classes of 45 students, were designated as control groups. McDivitt started his study with a pretest covering his educational objectives; European geography, the Munich Conference, comparisons of Soviet communism and Nazi Germany, and the reason for WWII. The study was conducted for one week. Students in the control classes received traditional instruction involving textbooks, reading assignments, and in-class discussion, on the objectives; the test group played Making History, conducted class room discussion, but did not open a textbook. The test group did exceedingly well in all objectives. It is also not e worry that the t... ...allows students time to continually work through problems, until the objectives are reached. Because of immediate feed-back, experimental learning is possible. Experimental learning is best defined as â€Å"learning by doing.† Video games can convey skills gradually, and allow the player to make mistakes, and retry; Practices which could be costly or dangerous in the real-world. They can also give the look, feel, and decision making challenges of a task, better preparing the student for real-life application (Why Games, 2011). Third, â€Å"the most obvious and logical conclusion is that they engage the students† (Hersh, 2009). Students are having fun while learning, creating competition, talking about it after class. Games automatically create a positive learning environment. â€Å"Well-designed video games are natural teachers,† explains Dr. Douglas Gentile (2009).

Cerebellar Lesions :: Neurology Medical Health Essays

Cerebellar Lesions The cerebellum integrates sensory and other inputs to coordinate ongoing movements and participate in motor planning. The cerebellum has no direct connections to the lower motor neurons but modulates motor function through upper motor neurons. The Vermis and flocculonodular lobes regulate balance and eye movements via connections with vestibular nuclei and oculomotor system, these regions control the medial motor systems. The more lateral areas of the cerebellum control muscles of extremities, the most lateral areas control function in motor planning. (Chapter 15 Cerebellum) When cerebellar lesions occur they produce ataxia (irregular uncoordinated movement.) Ataxia occurs ipsilateral to the side of the cerebellar injury. Midline cerebellar lesions cause unsteady gate (truncal ataxia) and eye movement abnormalities (nystagymas), which are often accompanied by vertigo, nausea and vomiting. Lateral cerebellar lesions cause limb ataxia. (Chapter 15 Cerebellum) Patients with cerebellar damage, regardless of the cause or location, exhibit persistent errors in movement. These movement errors are always on the same side of the body as the damage to the cerebellum, reflecting the cerebellum's unusual status as a brain structure in which sensory and motor information is represented ipsilateral rather than contra laterally. Furthermore, somatic, visual, and other inputs are represented topographically within the cerebellum; as a result, the movement deficits may be quite specific. For example, one of the most common cerebellar syndromes is caused by degeneration in the anterior portion of the cerebellar cortex in patients with a long history of alcohol abuse. Such damage specifically affects movement in the lower limbs, which are represented in the anterior spinocerebellum. The consequences include a wide and staggering gait, with little impairment of arm or hand movements. Thus, the topographical organization of the cerebellum allows cerebellar damage to disrupt the coordination of movements performed by some muscle groups but not others. The implication of these pathologies is that the cerebellum is normally capable of integrating the moment-to-moment actions of muscles and joints throughout the body to ensure the smooth execution of a full range of motor behaviors. Thus, cerebellar lesions lead first and foremost to a lack of coordination of ongoing movements. For example, damage to the vestibulocerebellum impairs the ability to stand upright and maintain the direction of gaze. The eyes have difficulty

An investigation of the affect of the concentration an of the rate of :: GCSE Chemistry Coursework Investigation

An investigation of the affect of the concentration an of the rate of reaction. Introduction. We are trying to find out the affect of acid concentration on the rate of reaction, we are using 2, 1.5, 1, 0.5, 0.25 Molar acid. In our experiment, we are reacting it with sodium thiosulphate. The collision theory will be involved in this, for instance the more concentrated the acid we use, the faster the reaction will occur and the lower the concentration the slower the reaction will occur, this is because the collision theory says that if something is more concentrated then it will collide more because there will be more of the substance. We could use a catalyst to speed up the reaction, this allows the molecules to move around easier to help them to collide more to speed up the reaction for instance say that people are trying to get over wall it is possible but it will take a slow process and say that we add a catalyst, our catalyst is a ladder this enables the people (molecules) to get over the wall quicker and easier than they normally would. In this experiment we need to control the amount of acid, amount of water, chemicalswater temperature amount of sodium thiosulphate and to all agree when the x is gone on the paper. We need to be safe when doing this by wearing goggles and making sure that we dispose of the end result chemical in a large beaker in the fume cupboard and not down the sink, we also need to make sure we do not lean over the conical flask when we perform the experiment because the chemical fumes are pungent and are not good to breath in. Method. We are going to measure the rate of reaction by how fast or slowly the mix of chemicals and water goes cloudy by placing a piece of paper with a cross on it underneath the conical flask and all agreeing when it has disappeared from sight. In this experiment we will need to use the following: Equipment Use Stop clock To time the experiment Conical flask To collect all the chemicals together in Burette To measure accurately all the chemical and water Sodium thiosulphate Chemical used in this experiment Hydrochloric acid Chemical used in this experiment, we will use 2, 1.5, 1, 0.5 and 0.25 molar strengths Water Used in this experiment, used in dilutions Paper Used along with cross of colour to determine when mixture is cloudy enough Beakers Used to hold the chemicals and water Dilutions To obtain the different strengths of hydrochloric acid we will need to dilute 2 molar acids and dilute it with water to reach the appropriate

The Silver Linings Playbook Chapter 2

He Does Not Preach Pessimism My workout is interrupted midday, when Mom descends the basement stairs and says I have an appointment with Dr. Patel. I ask if I can go later that night, after I have completed my daily weights routine, but Mom says I'll have to go back to the bad place in Baltimore if I do not keep my appointments with Dr. Patel, and she even references the court ruling, telling me I can read the paperwork if I don't believe her. So I shower, and then Mom drives me to Dr. Patel's office, which is the first floor of a big house in Voorhees, just off Haddonfield – Berlin Road. When we arrive, I take a seat in the waiting room as Mom fills out some more paperwork. By now, ten trees must have been cut down just to document my mental health, which Nikki will hate hearing, as she is an avid environmentalist who gave me at least one tree in the rain forest every Christmas – which was really only a piece of paper stating I owned the tree – and I do feel bad now for making fun of those gifts and won't ever poke fun at the diminishing rain forest in the future when Nikki comes back. As I sit there flipping through a Sports Illustrated, listening to the easy-listening station Dr. Patel pumps into his waiting room, suddenly I'm hearing sexy synthesizer chords, faint highhat taps, the kick drum thumping out an erotic heartbeat, the twinkling of fairy dust, and then the evil bright soprano saxophone. You know the title: â€Å"Songbird.† And I'm out of my seat, screaming, kicking chairs, flipping the coffee table, picking up piles of magazines and throwing them against the wall, yelling, â€Å"It's not fair! I won't tolerate any tricks! I'm not an emotional lab rat!† And then a small Indian man – maybe only five feet tall, wearing a cable-knit sweater in August, suit pants, and shiny white tennis shoes – is calmly asking me what's wrong. â€Å"Turn off that music!† I yell. â€Å"Shut it off! Right now!† The tiny man is Dr. Patel, I realize, because he tells his secretary to turn off the music, and when she obeys, Kenny G is out of my head and I stop yelling. I cover my face with my hands so no one will see me crying, and after a minute or so, my mother begins rubbing my back. So much silence – and then Dr. Patel asks me into his office. I follow him reluctantly as Mom helps the secretary clean up the mess I made. His office is pleasantly strange. Two leather recliners face each other, and spider-looking plants – long vines full of white-and-green leaves – hang down from the ceiling to frame the bay window that overlooks a stone birdbath and a garden of colorful flowers. But there is absolutely nothing else in the room except a box of tissues on the short length of floor between the recliners. The floor is a shiny yellow hardwood, and the ceiling and walls are painted to look like the sky – real-looking clouds float all around the office, which I take as a good omen, since I love clouds. A single light occupies the center of the ceiling, like a glowing upside-down vanilla-icing cake, but the ceiling around the light is painted to look like the sun. Friendly rays shoot out from the center. I have to admit I feel calm as soon as I enter Dr. Patel's office and do not really mind anymore that I heard the Kenny G song. Dr. Patel asks me which recliner I want to relax in. I pick the black over the brown and immediately regret my decision, thinking that choosing black makes me seem more depressed than if I had chosen brown, and really, I'm not depressed at all. When Dr. Patel sits down, he pulls the lever on the side of his chair, which makes the footrest rise. He leans back and laces his fingers behind his tiny head, as if he were about to watch a ball game. â€Å"Relax,† he says. â€Å"And no Dr. Patel. Call me Cliff. I like to keep sessions informal. Friendly, right?† He seems nice enough, so I pull my lever, lean back, and try to relax. â€Å"So,† he says. â€Å"The Kenny G song really got to you. I can't say I'm a fan either, but †¦Ã¢â‚¬  I close my eyes, hum a single note, and silently count to ten, blanking my mind. When I open my eyes, he says, â€Å"You want to talk about Kenny G?† I close my eyes, hum a single note, and silently count to ten, blanking my mind. â€Å"Okay. Want to tell me about Nikki?† â€Å"Why do you want to know about Nikki?† I say, too defensively, I admit. â€Å"If I am going to help you, Pat, I need to know you, right? Your mother tells me you wish to be reunited with Nikki, that this is your biggest life goal – so I figure we best start there.† I begin to feel better because he does not say a reunion is out of the question, which seems to imply that Dr. Patel feels as though reconciling with my wife is still possible. â€Å"Nikki? She's great,† I say, and then smile, feeling the warmth that fills my chest whenever I say her name, whenever I see her face in my mind. â€Å"She's the best thing that ever happened to me. I love her more than life itself. And I just can't wait until apart time is over.† â€Å"Apart time?† â€Å"Yeah. Apart time.† â€Å"What is apart time?† â€Å"A few months ago I agreed to give Nikki some space, and she agreed to come back to me when she felt like she had worked out her own issues enough so we could be together again. So we are sort of separated, but only temporarily.† â€Å"Why did you separate?† â€Å"Mostly because I didn't appreciate her and was a workaholic – chairing the Jefferson High School History Department and coaching three sports. I was never home, and she got lonely. Also I sort of let my appearance go, to the point where I was maybe ten to seventy pounds overweight, but I'm working on all that and am now more than willing to go into couples counseling like she wanted me to, because I'm a changed man.† â€Å"Did you set a date?† â€Å"A date?† â€Å"For the end of apart time.† â€Å"No.† â€Å"So apart time is something that will go on indefinitely?† â€Å"Theoretically, I guess – yes. Especially since I'm not allowed to contact Nikki or her family.† â€Å"Why's that?† â€Å"Umm †¦ I don't know, really. I mean – I love my in-laws as much as I love Nikki. But it doesn't matter, because I'm thinking that Nikki will be back sooner than later, and then she'll straighten everything out with her parents.† â€Å"On what do you base your thinking?† he asks, but nicely, with a friendly smile on his face. â€Å"I believe in happy endings,† I tell him. â€Å"And it feels like this movie has gone on for the right amount of time.† â€Å"Movie?† Dr. Patel says, and I think he would look exactly like Gandhi if he had those wire-rim glasses and a shaved head, which is weird, especially since we are in leather recliners in such a bright, happy room and well, Gandhi is dead, right? â€Å"Yeah,† I say. â€Å"Haven't you ever noticed that life is like a series of movies?† â€Å"No. Tell me.† â€Å"Well, you have adventures. All start out with troubles, but then you admit your problems and become a better person by working really hard, which is what fertilizes the happy ending and allows it to bloom – just like the end of all the Rocky films, Rudy, The Karate Kid, the Star Wars and Indiana Jones trilogies, and The Goonies, which are my favorite films, even though I have sworn off movies until Nikki returns, because now my own life is the movie I will watch, and well, it's always on. Plus I know it's almost time for the happy ending, when Nikki will come back, because I have improved myself so very much through physical fitness and medication and therapy.† â€Å"Oh, I see.† Dr. Patel smiles. â€Å"I like happy endings too, Pat.† â€Å"So you agree with me. You think my wife will come back soon?† â€Å"Time will tell,† Dr. Patel says, and I know right then that Cliff and I are going to get along, because he does not preach pessimism like Dr. Timbers and the staff at the bad place; Cliff doesn't say I need to face what he thinks is my reality. â€Å"It's funny, because all the other therapists I've seen said that Nikki wouldn't be back. Even after I told them about the life improvements I have been making, how I am bettering myself, they still were always ‘hating on me,' which is an expression I learned from my black friend Danny.† â€Å"People can be cruel,† he says with a sympathetic look that makes me trust him even more. And right then I realize that he is not writing down all my words in a file, which I really appreciate, let me tell you. I tell him I like the room, and we talk about my love of clouds and how most people lose the ability to see silver linings even though they are always there above us almost every day. I ask him questions about his family, just to be nice, and it turns out he has a daughter whose high school field hockey team is ranked second in South Jersey. Also he has a son in elementary school who wants to be a ventriloquist and even practices nightly with a wooden dummy named Grover Cleveland, who, incidentally, was also the only U.S. president to serve two terms that were not back-to-back. I don't really get why Cliff's son named his wooden dummy after our twenty-second and twenty-fourth president, although I do not say so. Next, Cliff says he has a wife named Sonja, who painted the room so beautifully, which leads to our discussion about how great women are and how it's important to treasure your woman while you have her because if you don't, you can lose her pretty quickly – as God really wants us to appreciate our women. I tell Cliff I hope he never has to experience apart time, and he says he hopes my apart time will end soon, which is a pretty nice thing to say. Before I leave, Cliff says he will be changing my medication, which could lead to some unwanted side effects, and that I have to report any discomfort or sleeplessness or anxiety or anything else to my mother immediately – because it might take some time for him to find the right combination of drugs – and I promise him I will. On the drive home I tell my mother I really like Dr. Cliff Patel and am feeling much more hopeful about my therapy. I thank her for getting me out of the bad place, saying Nikki is far more likely to come to Collingswood than to a mental institution, and when I say this, Mom starts to cry, which is so strange. She even pulls off the road, rests her head against the steering wheel, and with the engine running, she cries for a long time – sniffling and trembling and making crying noises. So I rub her back, like she did for me in Dr. Patel's office when that certain song came on, and after ten minutes or so, she simply stops crying and drives me home. To make up for the hour I spent sitting around with Cliff, I work out until late in the evening, and when I go to bed, my father is still in his office with the door shut, so another day passes without my talking to Dad. I think it's strange to live in a house with someone you cannot talk to – especially when that someone is your father – and the thought makes me a little sad. Since Mom has not been to the library yet, I have nothing to read. So I close my eyes and think about Nikki until she comes to be with me in my dreams – like always.

Renaissance history

â€Å"Renaissance is a term with a variety of meanings, but is used widely in discussion of European history. Renaissance originates from the Latin word â€Å"Rinascere† and refers to the act of being reborn. It is believed that during the time from about 1400AD to around 1600AD, Europe was reborn. Originally the term Renaissance only referred to the time when man rediscovered the knowledge of the ancient Greeks and Romans. However, modern historians have realized these rediscoveries were also crucial to the formation of modern culture. The term Renaissance is now used to indicate all the historical developments that have inspired the end of the Middle Ages and the beginning of modern history. Thus, the term Renaissance has now taken on a more significant meaning: not only does the Renaissance mean the rebirth of knowledge, but also represents a step from the past and a leap towards the future. The Renaissance overlapped the end of a period in European history called the Middle Ages. During this time, the great accomplishments of the ancient Greeks and Romans had been largely, though not entirely forgotten. With the ending of the Middle Ages, the Renaissance great cultural movement arose. Beginning in Italy, the new Renaissance spirit spread to England, France, Germany, The Netherlands, Spain and other countries. In Italy during the 14th and 15th centuries certain scholars and historians began to display a remarkable new historical self-consciousness. They believed their own time was a new age, at once sharply different from the barbaric darkness which was imagined had occurred in the centuries before. They grew to believe that there was more to be discovered about mankind and the world, than medieval people had known. The Italians are very eager to rediscover what clever Greeks and Romans had known in ancient times, as well as making their own intelligent attempts to understand the world. This renewed interest in the world and in mankind is called Humanism. Humanism was the most significant intellectual movement of the Renaissance. Humanism during the Renaissance received its name from one of the earliest concerns of the humanists: the need of a new education curriculum that would empathize a group of subjects known collectively as the ‘Studia Humanitatis† involving grammar, history, poetry, ethics, and rhetoric. However, this new education curriculum conflicted directly with the traditional education, which involved logic, science and physics, and often sharp clashes occured between the two educators. However, more was at stake than the content of education. The traditional education was intended chiefly to prepare students for careers in medicine, law, and above all theology. To Renaissance humanists this seemed too narrow, too abstract and too exclusively intellectual. They proposed a system of education that centred on the general responsibilities of citizenship and social leadership. Humanities essential contribution to the modern world is not found in its concern with ancient knowledge, but in its new attitude of flexibility and openness to all the possibilities in life. With people receiving education-involving leadership, they began to gain more confidants. More people began to reject ideas about science put forward by the ancient Greeks and began to search for the truth. They realized that the Greeks† ideas were often intelligent, but also often wrong. Many people still did not want the old ideas disapproved, and threatened scientists to stop having new ideas. However, this did not stop many brilliant scientific inventions being produced at this time. A great scientist of the Renaissance was the Polish student Nicolaus Copernicus who developed the theory that the earth was a moving planet. He is considered the founder of modern astronomy. In Copernicus† time, most astronomers accepted the theory the Greek astronomer Ptolemy had formulated nearly 1400 years earlier. Ptolemy stated that the Earth was the centre of the universe and motionless. He also stated that all the observed motions of the heavenly bodies were real and that those bodies moved in complicated patterns around the Earth. As the church supported Ptolemy theory no one dared to challenge it until Copernicus. Copernicus believed Ptolemy†s theory was too complicated. He decided that the simplest and most systematic explanation was that every planet, including the Earth, revolved around the sun. The Earth also had to spin around its axis once every day. Copernicus couldn†t prove his theory, but his explanation of heavenly motion was mathematically strong and was less complicated than Ptolemy†s theory. The later work of later scientists such as Galileo Galilei helped to prove that Copernicus† theory was correct. Galileo was a Florentine physicist, philosopher, and inventor, whose name became the chief emblem of Renaissance science and of ensuing technological revolution. In 1609, he heard that the rulers of Florence and Venice were searching for someone who could invent an instrument that made distant objects appear closer. Galileo set to work to construct one, and within a few days he had finished, naming it a telescope. During the winter, he turned his telescope to the sky with startling results. He announced that the moon surface was quite similar to earth†s – irregular and mountainous; the Milky Way was made up of a host of stars; and the planet Jupiter is accompanied by at least four satellites. The electrifying effects of these discoveries were amazing. They showed the human senses could be aided artificially to discover new truths about nature, something that neither philosophy nor theology had previous contended with. However, most importantly Ptolemy†s astronomical theory was impossible. Galileo had proven Copernicus theory correct. Galileo had great importance upon the history of ideas.
