Galileo Galilei founder Of Modern Experimental Science :: essays research papers

Galileo Galilei "founder of modern experimental science" Galileo Galilei was one of the most remarkable scientists ever. He discovered many new ideas and theories and introduced them to mankind. Galileo helped society as an Italian astronomer and physicist, but how did he come to be such a great and well-known scientist? It took hard work and patience.... Galileo was born during the renaissance in Pisa, Italy on February 15, 1564. He was raised by his mom, Giulia Ammanati, and his dad, Vincenzo Galilei. His family had enough money for school, but they were not rich. When he was about seven years old, his family moved to Florence where he started his education. In 1581, his father sent him to the University of Pisa because he thought his son should be a doctor. For four years, he studied medicine and the different theories of the scientist Aristotle. He was not interested in medicine, but soon he became interested in math. In 1585, he convinced his father to let him leave the school without a degree. Galileo was a math tutor for the next four years in Florence. He spent a lot of the four years studying the scientific thoughts and philosophies of Aristotle. He also invented an instrument that could find the gravity of objects. This instrument, called a hydrostatic balance, was used by weighing the objects in water. Galileo returned to Pisa in 1589 and became a professor in math. He taught courses in astronomy at the University of Pisa, based on Ptolemy's theory that the sun and all of the planets move around the earth. Teaching these courses, he became more understanding of astronomy. In 1592, the University of Padua gave him a professorship in math. He stayed at that school for eighteen years. He learned and believed Nicolaus Copernicus's theory that all of the planets move around the sun, made a mechanical tool called a sector, explained the tides based on Copernican theory of motion of earth, found that the Milky Way was made up of many stars, and told people that machines cannot create power, they can only change it.

Nature Nurture Debate Essay

?NATURE VERSUS NURTURE IS THE ARGUMENT OF WHETHER IT IS the characteristics that are inherited, or those that are learnt through environmental influences, which effect how we develop. ?WE ARE GOING TO LOOK INTO THE DIFFERENT PSYCHOLOGICAL approaches in relation to whether it is nature or nurture that determines gender: ?Psychodynamic ?Biological ?Social Learning ?Cognitive Sex and Gender Sex and gender are often referred to as one and the same, so it is important to distinguish between certain words and phrases: ?Sex: The biological state of a person; whether they are male or female depending on their genetic makeup. ?Gender: This is the social interpretation of sex. Is an individuals classification on whether a person is male or female. ?Gender Identity/ Role: Through socialisation we learn what is acceptable behaviour from females and males. We learn that each have different expected characteristics. ?Gender Constancy: Is the realisation that gender is fixed. This happens at 4 years of age. Psychodynamic Approach ?Freud backs up both the nature and nurture, with his psychodynamic approach: ?His idea of the personality being in three parts: the Id, Ego, and Superego. ?The Id is what we are said to have acquired naturally in birth. It is the primitive self, who strives to survive. Psychodynamic Approach ?The ego develops a few months in, and continues to be learnt from the outside world, it is when our consciousness comes into play. A child would learn the di$erence between male and female. ?The superego is the internalisation of moral values. We strive to do the right thing. So a child may have it instilled to act a certain way because that is what is expected, so any other feelings may be pushed into the unconscious. Psychosexual Stages ?In Freuds Psychosexual stages, it is the Phallic stage at age 3 to 6 years old that children become gender aware. ?A child is aware of what sex they are biologically, but their gender is e$ected by interactions between mother and father. Psychodynamic Theory ?However the personality model Freud talks about cannot be proved. ?This approach is also deterministic in that there is no free will when it comes to the psychosexual stages Little Hans Case Study Biological Approach All that is psychological is psysiological ? rst ‘Aron’. Social Learning Approach Cognitive Approach Conclusion ? There is no doubt that sex is based solely upon nature, whereas determining gender brings together both nurture and nature as it is the how society views the sexes. All that is psychological is psysiological ? rst ‘Aron’. Thought’s, feeling’s, ect, reside in the mind and are ultimately of biological cause. Biological psychology is the study of the physiological basis of behaviour and experience, it is highly scienti+c in approach, the key areas of study include:- †¢The nervous system and behaviour †¢States of consciousness †¢Biological rythms †¢Motivation †¢Anxiety and stress †¢pain Biological Psychology Cognitive is mainly a consequence of maturation stages of innate structures Biological Biological psychology states:- †¢Human Behaviour can be explained through hormones, genetics, evolution and the nervous system †¢If in theory, behaviour can be explained biologically, causes for unwanted behaviours can be modi+ed or removed using biological treatment such as medication for mental illnesses. †¢Biological psychology believes in experimental treatment conducted using animals, this is due to our biological similarities. Biological Charles Darwin †¢Was an 18th century English naturalist and geologist. †¢Best known for his contributions to evolutionary theory. †¢Whilst on a 5 year expedition, Darwin concluded species of life have descended over time from common ancestors. †¢This created the scienti+c theory to a branching pattern of evolution resulted from a process he called natural selection. †¢For 20 years Darwin worked on his theory †¢1859 The origin of species was published †¢The book was extremely controversial, mainly due to the theory of homo sapiens being another form of animal, leading to a theory of our evolution from apes†¦Ã¢â‚¬ ¦. The church was not happy. Biological Studying psychology within an evolutionary framework has revolutionized the +eld, allowing di$erent approaches to be uni+ed under one banner. Darwin also pioneered one of evolutionary psychology’s most important tools, the comparative method. The results coming from this new +eld continue to change how we view our behavior and mental abilities, as well as those of other animals. Darwin’s impact in biological Psychology Biological Strengths and weaknesses biological psychology and the theories within support nature over nuture. However, it can be argued, that by limiting explanations for behaviour in terms of either nature or nurture, the complexity of human biengs is underestimated. It could be argued, that the interaction of both nature (biology) and nurture (environment) both play vital roles in our behaviour. A strength to the biological approach is its use of scienti+c methods, producing clear evidence, such as neurotransmitters. The biological approach is able to produce clear evidence, scienti+cally, for explanations A weakness to biological psychology is the reductionist explanations provided, which do not fully encompass the full scope of human behaviour. Individuals may posses a predisposition, to particular behavioural traits, however, environmental factors can also be the cause. This is called ‘Diathesis stress model’ of human behaviour. Biological Biological explanation of gender. Through evolution, men in their role as ‘hunter gatherer’, may have developed a stronger ‘+ght or ;ight response than women, who had the role of caring for the children. Due to this males and females may have developed a di$erent physiological response to stress. Taylor et al (2000) suggested that women produce a calmer response to stress due to a hormone. Oxytocin is realised in response to stress and has been shown to lead to maternal behaviour. Taylor called this the ‘tend and berfriend response’ instead of the ‘+ght or ;ight’ response. Leading to the idea women are more likely to seek social support to cope with stress.

“Nowhere Man” by Pico Iyer Essay

â€Å"Nowhere Man† by Pico Iyer talks about how being a transit lounger has it’s ups and downs. Packing and waiting for your next plane as soon as you’re about ready to just sit down and rest. From sleeping in airports to eating almost all of your meals off of plastic plates. I could relate to Iyer to some level but fully. Being a visitor in your home is never a good feeling to experience but seeing the world through your eyes is such a blessing as well. I thought that nationalism was the only thing that created â€Å"monsters† but after reading this piece, I believe that both nationalism and internationalism create â€Å"monsters†. Themes that I picked up while reading this piece were – independence, nationalism, internationalism, lack for sense of home, family and comfort, discovery, self-discovery, exhaustion, loneliness, confusion. I really enjoyed a lot of the sentences that Iyer wrote but one that really caught my attention was, â€Å"We pass through countries as through revolving doors, resident aliens of the world, impermanent residents of nowhere†. This sentence really caught my attention because not only were these words put together very well but they also have a deeper meaning behind them. To me, this sentence means that they were always in a hurry to get from country to the other in time and all though they were always traveling, they never had the true meaning of a â€Å"home† but yet had a house wherever they traveled to. When Iyer said, â€Å"We are visitors in our home† – it really hit home because whenever I go over to my dads house, I feel like such a visitor although I’m suppose to feel like it’s my second home because it’s my dads house. I’m not sure what he felt when he wrote it but when I write it or talk about, I feel empty as though so mething is missing. Personally, I would have a love/hate relationship if I were a transit lounger, not knowing where home is. I would love it because I get to travel the world, discover new cities and meet new people but I would hate it because I would most likely constantly get asked where I live and I would hate to say â€Å"I don’t actually have a home but I’m going to Madrid next!†. If I didn’t have a home, I would probably lose my sense of family and comfort.  I wouldn’t know where I could go back to when I get tired of traveling, once I’m overwhelmed with seeing new cities and meeting new people. But it would also help me build a sense of independence and I would have an exciting lifestyle. Being a transit lounger sure does have it’s deep cons and pros. Two questions: – If he wasn’t a transit lounger, would he still be the same person he is today? Would he be as independent as he is today? – Did any of the other students relate to Iyer when he mentioned â€Å"†We are visitors even in our home†?

Performance appraisal Essay Example

Performance appraisal Essay Example Performance appraisal Essay Performance appraisal Essay The success behind for all multination companies, team work is playing an important role. Multinational team can provide a perfect development opportunity for an organisations future leaders. Experience of working on effective global team help the team member to increase their management skillness, make them able for facing the challenges for developing and employing the knowledge and skill that are necessary for leading global organizations (Maznevski and DiStefano, 2000). In the company like Hume and Co, there is hardly any team work practised among the consultants. Young consultants are working individually rather collectively by diverting clients from other colleagues. By ensuring strong support to IT consultants from Human Resource professionals will definitely increase their effectiveness, enhanced their knowledge and skill required for building global team effectiveness (Canney Davison Ward, 1999). However, other multinational companies can be mentionable who succeed in using global team appropriately. General Motors has used its global teams in its Research Development (RD) activities for examining the feasibility of producing global cars. Since globalized Coopers Lybrand has been using global teams successfully in serving customers, that finally seen rapid growth in production (Jackson Schuler, 2000: 146) Global leaders have to be experts in learning and adapting their thinking in new paths. Martha L. Maznevski and Joseogh J. DiStefano have identified three key areas where global leaders need to establish their strong efficiency. 1) learning and adapting 2) managing relationships 3) managing ambiguity (2000). In Frankfurt office, Germany the manager used to work in a local company before taking charge of the office. He does not have international managerial experience which is normally required for successfully running company which is looking for expanding its presence globally. In question of managing relationship, the local manager does not have knowledge in corporate culture which means basic assumptions and beliefs held by employees about the enterprise they work for (ucs. mun. ca). Lack of expertise in international managerial experience is another hr issue which creates problems in developing brand, not only for the clients but for the staff as well. On going projects is suddenly postponed following consultants quitting the office. Failing to comply close relationship with the Head Quarter, is revealing lack of managerial efficiency of the manager. Besides, having lack ness of knowledge in company policy and strategy regarding globalisation, local staff are deprived of gaining knowledge in company policies. On the basis of case study, Hume Co. does not posses any definite hr planning that they can enforce in other areas of the world where their business is in operation. Each of the strategic type of firm is required to formulate different types of hr strategy regarding their business structure (Miles and Snow cited by Guest, 1997:264). Companies adopting business strategy and human resource strategy will have superior performance (Guest, 1997).

How to Define Atmosphere

How to Define Atmosphere The term atmosphere has multiple meanings in science: Atmosphere Definition Atmosphere refers to the gases surrounding a star or planetary body held in place by gravity. A body is more likely to retain an atmosphere over time if gravity is high and the temperature of the atmosphere is low. The composition of the Earths atmosphere is about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, with water vapor, carbon dioxide, and other gases. The atmospheres of other planets have a different composition. The composition of the Suns atmosphere consists of about 71.1 percent hydrogen, 27.4 percent helium, and 1.5 percent other elements. Atmosphere Unit An atmosphere is also a unit of pressure. One atmosphere (1 atm) is defined to be equal to 101,325 Pascals. A reference or standard pressure is commonly 1 atm. In other cases, Standard Temperature and Pressure or STP is used.

Across The Universe - Essay Example The film is brilliant for its daringness and like the war in Vietnam; the film does not quite stop in the achievement of its goals. It reaches something more powerful in the quest for success. The music that is used in the first part of the film fits well with the story, from a fantastic dancing number, to Lucy when she is gently musing on the potential romance with Jude through singing. At the end of the film, the song morphs into a dance that can be said to be seductive between Jojo and Sadie. This is a brilliant balance of the inherent romance and the song’s darkness (Taymor 1). At the start, of the film, the music that has been used binds well to the situation and what is taking place in the film. Through this, the film highly captures the viewer’s attention. Some may argue that when watching the film, only the actors and the screenplay matter; however, this is not true as proved by this film. Films have to match the message with the background music played to maintain the viewer’s attention and show progress in the movie. A song can also be used to introduce a new theme or emphasize on a current them is a film (Taymor 1). Halfway through this film, the musical numbers get more visually splendid and weirder and the story seems to lose its way. This one effect is attributed to the wrong choice of song. The film writer has to ensure that the theme of the song coincides with the theme that the film is trying to advocate for, if the theme of the song does not correspond with the film’s theme, then the film will lose its way and will not achieve the required goal (Taymor 1). In the film, the actors use songs to emphasize the feelings that they are portraying especially the main casts. At some point when Sadie tells the rest of the band that Lucy is planning on going solo, Jojo intentionally spoils Lucy’s’ opening song.  Ã‚

Econ2010-4 - Assignment Example es identifying â€Å"Social Cost†; market â€Å"equilibrium quantity consumed and price†; â€Å"external cost of antibiotic use†; â€Å"deadweight loss†; â€Å"efficient equilibrium† if one exists; and â€Å"private value†. 3. Earlier in the Economics 2010 course we learned that a tax on an ordinary good increases deadweight loss. Does the same impact result with the imposition of a tax on a good with an external cost? Explain. Yes; a tax would cause a change in the equilibrium price and quantity resulting to a inefficient market. 4. Explain the use of the â€Å"COASE THEOREM† in solving private problems of externalities. Under what conditions does the Coase Theorem breakdown as a mechanism for solving private externality issues and restoring efficient market equilibrium allocation? Explain. The theorem states that in case there is a conflict of property rights the parties involved may negotiate on terms that seem to be more beneficial to them than the assigned rights of the property. The theorem will breakdown when there are huge costs associated with bargaining. 5. Explain and/or graph with explanation the difference between controlling and regulating a negative externality by use of a â€Å"Corrective Tax†; a â€Å"Pollution permit system and market†, or a â€Å"Command and control† regulation. Explain the pros and cons of these 3 types of resolution of the negative externality problem. It is the summation of all the sales that a company makes together with other additional sources if incomes for a given period of time during the production process for a given product. It is usually given as Total revenue = price Ãâ€" quantity + other incomes Opportunity cost is the cost that somebody suffers for choosing the alternative decision over the other and it is always considered that the best choice is made between the options; the lesser privileged choice is foregone to pursue the other for more benefits to be yielded. The cost of the neglected choice is considered
