Hindu Influences in America Essay Example for Free

Hindu Influences in America EssayDiscuss some Hindu influences in America.Hinduism has had an influence in America since being introduced by Swami Vivekananda in 1893, at the Worlds Parliament of Religions. Religion is a complex component of our lives and it encompasses much more than our own particular traditions or personal experiences. Hinduism has had a objurgation on interests around vegetarian concentration, yoga meditation, reincarnation and alternative medical treatments that have become popular in the United States. Hinduism has also introduced words, such as yoga, mantra, and chakra, to name a few, that have been incorporated into the American language as quasi-religious practices. As Hinduism grows in populations so does the interests in what the religion has to offer. Yoga is used as a remainder exercise to unite oneself with God or ones true self. Yoga practices have become so popular and widespread that newer populations may mistake them as being unaccompanied A merican tradition. Mantra is a means of chanting or meditating and consists of a set of sacred words or syllables used to unite one with the deity they represent.These be some of the benefits Americans feel provide them with a newfound faith. Hindus of Indian descent in America have created a balance between their religion and Indian cultural religion with the pressures to Westernize. Temples have been built in American in the styles of northern or southern India and dedicated by Hindu priests from India. These temples create a place to worship. There is always the threat that modern American traditions, such as eating meat, racial intermarriage, and considerable mobility in society may interfere. The temples pick up the serious seeker of non-Indian descent which speaks well for Hindu hospitality. The population of Hindus is continually growing in America. It is believed that Hinduism isnt just a faith but is related to the concretion of reason and intuition. As most Americans we find new things intriguing by feeling they may bring us closer to oneself or to God. In my flavour it is likely that this belief will continue to entice Americans in the years to come.

The Major Components Of Green Computing Information Technology Essay

The Major Components Of putting green Computing Information Technology EssayAs IT has become a study component in social infrastructure, it plays a vital role in humans life. Computing is a fast growing atomic number 18a which consumes vigour a lot. A reckoner which performs well consumes lots of energy. It takes a lot of energy to create, package and retrieve data. With the development of the technologies, people tend to depend on these technologies to a greater extent and more. It will lead us to many problems as energy is a non renewable resource. It will soon cost more to big businessman a calculating machine in future, than buying a new one today. Therefore we have to find methods, where we can minimize the wastage of energy while utilizing existing resources efficiently.Since computer plays a major role in our lives, demand for the energy, cost and wastage also increase dramatically. According to the Climate Saving Computing Initiative, the half of the power input to our PC is wasted withtaboo even reaching to the processor, memory, disk or any other component. Further, they have identified that added heat of the computer systems, inactive sleep and hibernate raise of the computer and mal practices of using electronic equipments has a great impact in this energy wastage. It is estimated that out of $250 billion per year spent on powering computers worldwide single most 15% of that power is spent computing. The rest is wasted idling.Therefore, kelvin Computing is introduced in order to maximize the energy efficacy and increase the recyclability of products and the grind waste. parking lot Computing is focusing on creating technologies that help to preserve nature and minimize the bad effects of the technological development.OverviewGreen Computing is an echo favourable approach to the modern computing environment. It discusses about the substances of using computers in environmental friendly way. The main focus of Green computing is reducin g the environmental impact of industrial processes and innovative technologies ca finishiced by the Earths growing population and the ways of utilizing computer resources efficiently. It talks about serving social needs in a way which reduce the damage happen to the nature. Mainly this is talking about creating recyclable products, reducing pollution, providing alternatives to certain technological areas and etc. It is a concept which is already utilise in the IT environment. Researchers have found that most of the computers are not used for most of the time, but they are left running and many individualized computers are left on unnecessarily. It leads to the high wastage of energy. These kinds of issues are also considered in Green Computing. It also talks about proper disposal of electronic waste.Eco gracious ComputingGreen Computing is also known as Green IT. Environmental sustainability, Energy efficiency, and the cost of disposal and cycle also includes in Green IT.Histo ryThe Energy Star program commenced by the U.S. Environmental Protection Agency in 1992 was the first voluntary labelling program designed to promote and confess energy efficiency. It is basically designed to promote and recognize energy efficiency in monitors, climate control equipments and other technologies. The term Green Computing immerged concisely after this Energy Star Program. The first function launched as a result of the Green Computing researches was the sleep mode function of computer monitor.Approaches to Green ComputingIn order to gain the environmental sustainability and efficient use of energy through computing there are four main paths to be taken.Green Use victimisation the computers and other related products in an efficient manner where the energy consumption is minimized.Green Disposal Reusing old computers, properly disposing and recycling other unwanted products.Green Design Designing energy efficient and environmentally friendly computers and accessori es.Green Manufacturing Manufacturing computers and other related equipments in a way that they have a minimal effect to the environment.These four steps can be further spanned in to number of activities and areas.Efficient use of energy cause savingServer realisticizationEnvironmental sustainable designingResponsible disposal and recycleRisk mitigationUse of renewable energy sourcesEco- labellingUse of Green methodologies and assessment tools.As an initial step to the Green Computing the work habits of the individual computer users have to be changed. Most of the energy wastages regarding the personal computer usage happen because of the false beliefs regarding the computer usage. For an instance, people belief that when turning off a computer and turning on it back uses more energy than it leaving on. But the actual energy consumption of the computer when it boots up, is far less than the energy it uses when left on for more than three minutes. Further the use of notebook compute rs rather than using personal computers will also save energy. Moreover, people think that screen savers do save energy. But the fact is that they are designed to increase the lifetime of monochrome monitors. The screen savers will save energy if they actually turn off the screen or turn off the backlight of the laptops. By letting the users get to know about these facts will change their habits and it will lead to power utilization.When it comes to organizational level, many organizations have undertaken various kinds of activities as an approach to this Green IT.TelecommutingVirtualizationVoIPOrganizations have allowed their workers to work while being at home. This will help to reduce fuel emission at transportation. They are given all the necessary facilities to work. This is known as telecommuting. Virtualization refers to the consolidation of servers. It allows to two or more logical computer systems to run in one corporal hardware. This leads minimum power consumption and ma ximum cooling. VoIP or Voice over Internet Protocol is a technology of voice transmission over network or other packet switched networks. It reduces the telephone wiring infrastructure and is low cost. It is method of reducing metallic waste.Green business practicesGreen IT isnt just about energy efficiencies but also about operational efficiencies that can improve the organization. In most of the organizations, Green IT is practiced because of the explicit business drivers such as cost and the availability of the energy, cost of the equipments, cost of the data centres, business process optimization and performance and efficiency. When focusing on business optimization, hardly a(prenominal) areas can be targeted which energy demand can be reduced and growth can be increased with the help of IT.Server and storage utilization and consolidationServer, storage, and use virtualizationTechnology and breeding life cycle strategiesEnergy measurement and careGreen Information StrategyU nder Green Information Strategy, the ways of managing and retaining information has been defined. The ways of collecting, classifying and archiving information are introduced in Green Information Strategy.It involves several key stepsUnderstanding the requirements for information retention and availability.Determining infrastructure requirements.Conducting ceaseless strategic planning to meet economic and business conditions and demand.Measuring progress and adjusting the strategies.Information Lifecycle Management is a set of concepts which helps organizations to build processes and implement best practices for creating, storing, archiving, and stipulate data. A variety of technologies and methodologies can be used in order to optimize the storage utilization. Then the amount of storage required and the energy used to power will be reduced.Maximizing data centre and server room efficiencyDesigning a data centre for maximum efficiency is complex and requires input from many disc iplines not normally associated with IT. But most of the organizations dont have data centres. They have their IT equipments in a sever room. Server room is a data centre operated in a small scale. Here are few facts that have to be considered when designing a server room. raised(a) floor in computer rooms was the general accepted norm since vacuum tube era.Variable speed motors can tailor cooling power usage to need, producing substantial savings, and may prove less expensive in the long run though they are more expensive to purchase.The trend in servers is to pack more CPUs in to a single track. But when power densities get above 200 watts per square foot, because of the high heat generated, too overmuch air is needed to remove the heat. Therefore racks (19-inch EIA-310-D standard) with built-in chillers or even water-cooled servers, become preferable.Use a large server.Replace physical servers with virtual servers.Blade serversBlade servers put each processor, memory and hard dr ive on one single card called blade. These blades are fixed in to a backplane. A single power supply, a shared cooling system, a shared network interface is used among the blades, which connected to a backplane. Replacing duple servers with blade servers generally saves power and space.Green StorageStorage systems are among the systems which consume power and storage a lot. Drivers have to be full supply and running to be able to store data.Data DeduplicationData Deduplication is the term used for removing the duplicates. It examines the hard drive or the storage system and find out the duplicates and remove them. It effectively reduces the storage allocated for certain data file and allocates it to other additional data. It increases the capacity of your system.Thin ProvisioningThin provisioning is allocating right amount of storage is as needed. It helps to eliminate unused capacity. Storage can be used efficiently by allocating the required storage when it is needed and using s torage management software product to adjust it. As the storage is dynamically allocated the storage can be grown or shrink according to the action stored. Further storage management software can view applications simultaneously and allocate unused capacity as needed.Storage VirtualizationStorage virtualization gets all the available capacity together from binary storage systems and enables it to share, without requiring a change in storage hardware. By enabling sharing it avoids the trapped capacity, which is available but cannot be used by an application.Using VirtualizationMultiple applications and multiple Operating systems can be run simultaneously with the use of virtual memory technology. Virtualization increases the utilization of computer systems by condensing applications into few servers. Therefore the number of required servers will be reduced. It reduced the power consumption of the data centres and the cooling requirements.Virtualization is one of the earliest paths to green, because when more than one application is run on a server (application consolidation) the number of servers required to support these applications is reduced. Fewer servers mean less power consumption and low energy requirement for cooling.Future Directions on Green Computing

The Structure of the Kidney: Causes of Kidney Disease

The Structure of the Kidney Causes of Kidney DiseaseThe structure of the kidney The kidney is surrounded by the renal enclose and split into 3 sections, the medulla, the cortex and then the renal pelvis. Each kidney is supplied with oxygenated tune, by the renal artery and removes deoxygenated blood via the renal vein. Once the kidneys carry out their filtration mechanism, they exonerate their waste product, down the ureter.The nephron is the functional unit of the kidney and over a million of these be found within each kidney allowing it to carry out its function. bank note how it spans across the different kidney sections.(i) The juxtaglomerular apparatus is the main filtration of blood occurs in nephrons and this is where the glomerulus and Bowmans capsule interact.(ii) The mesengial cells are found closely associated with the filtration part of the juxtaglomerular apparatus and their position links with their determination in do inflammation in glomeruli.(iii) The Podocyt es are also found near glomerular capillaries and these whitethorn fuse together and influence the filtration of the glomerulus, ca utilise Hodgkins affection. This malady is a fount of swelling due to the pastime of accumulating products, which are not filtered and so deposited to other parts of the body.Glomerulonephritis (GN) is a type of kidney disease where by filtration of the blood is disrupted. It is mainly associated with the glomeruli in the kidneys, becoming inflamed (NHS Choices 2009) and there can be different types of the disease which may be proliferative or non-proliferative.The main pull in of the disease is not precisely known but, there are many possible explanations. The most common explanation for proliferative GN is due to an immune system response, where inflammatory cells interchangeable platelets or macrophages become trap in the glomeruli (Couser 1999). Here they circulate and accumulate, initiating a mechanism that widens to inflammation of the gl omeruli (Couser 1999). This is the mechanism for the most common form of proliferative GN, known as Immunoglobulin A (IgA) nephropathy (DAmico 1987). This is when IgA proteins, which fight infections, build up within the glomeruli and therefore inflammation (Geeky Medics 2010). Another immune system response involves antibodies interacting with antigens, organise by the glomerular root cellar membrane, which can also trigger inflammation (Watson and Royle 1987).Another possible explanation for proliferative GN is infection-related, following invasion by bacteria of the Streptoccoci origin (Ryan and Ray 2004), which targets the skin or pharyngeal tissue (Watson and Royle 1987). This results in post-infectious GN which can also be associated with other infections like bacterial endocarditis or HIV (Mayo Clinic 2009).In addition, it is also suggested that vasculitic disorders, like Wegeners Granulomatosis can result in crescentic GN (Geeky Medics 2010) (Figure 4).Crescentic GM In W egeners Granulomatosis, blood vessels become inflamed, having an effect on the filtration rate of the glomerulus and leads to the formation of crescent influence scars.Non-proliferative GN can be idiopathic, such as membranous GN, or may just simply be genetically linked like focal segmented GN (Geeky Medics 2010).When looking at GN (mainly proliferative) we need to also consider the mesengial cells (Figure 3, ii). GN can be recognised by an increase in the number of mesengial cells and their intracellular contents (Churg 2006). They speedily multiply, increasing the thickness of this layer and press against the glomerular capillaries (Churg 2006) (Figure 5).Histology of proliferative GN As the mesengial cells multiply, they increase in number and compress against the glomerular capillary and contribute towards the glomerulus increasing in circumference. Taken from (Churg 2006).In some cases, the mesengial cells may even invade the glomerular capillaries and sit in among the fi ltration part of the nephron, made up of endothelial cells and the basement membrane (Figure 6) (Churg 2006). Hence, the basement membrane appears split, disrupting renal filtration and therefore resulting in a certain type of GN, known as membranoproliferative GN (Hope et al. 1993).A Normal Glomerular capillary vessel Proliferation of the mesengial cells leads to invasion between the epithelial cells and the basement membrane, disrupting glomerular filtration and leading to GN. Taken from www.uncnephropathology.org/jennette/ch1.htmThe glomerular capillaries are also where proteins from the immune system may be trapped between the basement membrane and the epithelial cells, which accumulate and form humps in the glomerular capillary walls (Churg 2006), resulting in membranous GN (Hope et al. 1993).Specifically in crescentic GN, which is infection related, there is an increase in epithelial cells which compress the glomerulus and causes scars, described as crescent shaped (Malvinder 2008) (Figure 4).However there can be milder forms of GN, with the most common macrocosm minimal change GN, caused by the fusion of podocytes (Hope et al. 1993) (Figure 3, iii).When looking at post-infectious GN, we find that it is normally the group A beta-haemolytic streptococcus bacteria which causes infection (Watson and Royle 1987) and brings about bang-up post-streptococcal GN (APSGN) (Duvuru 2010). The activity of this bacterium is thought to be associated with the accumulation of streptococcal antigens, binding to the immune antibodies, which are then deposited on the glomerulus basement membrane (Field et al. 2010) (Figure 7).APSGN (Arrows show where the antigen-antibody complexes dumbfound been deposited.) As the antigen is bound to the antibodies, it prevents the antibodies from inflicting a defence mechanism and leads to modification of the glomerular basement membrane (Field et al. 2010).There are many signs and symptoms associated with GN, which can vary between t he different forms of GN, but there are common symptoms that are found in all types. As the glomeruli are obstructed, filtration is reduced and allows for blood to leak into the tubules and therefore this blood passes out into the urine (Watson and Royle 1987). The urine may also be described as cloudy and this is due to proteinuria. This is when excess serum proteins are passed out, in the urine (Nordqvist 2009) due to the impaired filtration mechanism (Field et al. 2010) . This excess serum may also be linked with symptoms of nausea and vomiting, which are also associated with GN (Unanue 2011). The urine may also be described as, haematuria, where red blood cells are lost, triggering anaemia in GN sufferers (Watson and Royle 1987). Another common symptom is swelling, as there is a diversion of accumulating products, which are not filter, to other parts of the body (Hicks 2009). Symptoms related to respiratory problems such, a sore throat or skin rash would be to a greater extent s ignificant in post-infectious GN due to streptococci bacteria infecting the pharyngeal tissue and the skin (Feldon et al. 2010). Another common symptom is hypertension, caused by salt and water rescue and therefore activation of the renin-angiotensin system (Field et al. 2010) (Figure 8).The Renin-angiotensin (aldosterone) system (RAS) As there is an accumulation of water and salt, the circulating volume also increases and activates RAS. RAS then vasoconstricts blood vessels, causing an increase in blood pressure, which is a symptom of GN.Diagnosis of GN, tends to be via Urinalysis, in order to find the presence of blood and proteins in the urine (Haggerty 2002). similarly a blood test can be taken and if there is an accumulation of waste products, such as creatinine or urea-nitrogen then this can guide GN (Haggerty 2002). The blood can also be checked for anti-streptolysin titre, due to reactions by streptococci bacteria and another indication of GN (Brunner and Suddarth 1990). Otherwise a much simpler wipe up of the throat could be used to detect the streptococcal infection, which is used widespread (Hicks 2009). A final diagnostic evaluation is by carrying out a renal biopsy in order to view the inflamed glomeruli and accumulation of cells surrounding the glomerular capillaries (Brunner and Suddarth 1990).These tend to be the most common diagnostic procedures but investigations can be made by means of other methods, like in radiology, where a renal ultrasound is used (Hope et al. 1993). interferences on GN sufferers can range and depends on the type of GN that they suffer from, but the main aim of suement is to promote kidney function and reduce symptoms of GN (Hicks 2009). By simply getting plenty of rest, until the urine becomes clear and levels of nitrogen-bearing waste products regularize, can encourage the regain of renal function and a reduction of the other symptoms associated with GN (Hope et al. 1993). Another treatment used is by regulating the pabulum and fluids of the GN sufferer, for example, by placing restrictions on dietary proteins and compensating for fluid loses by drinking plenty of fluids (Hope et al. 1993). It has been predicted that drugs which block the Angiotensin II receptors or ACE inhibitors may be a form of treatment, for reducing the effects of GN, but this is still be investigated (McMillan 2010). As there are different forms of the disease, different drugs may be used to treat each form, for example in GN caused by immune response, corticosteroids or immunosuppressant may be used, but this is not a definite treatment for GN (McMillan 2010). Treatment of vasculitic disorders like Wegeners granulomatosis, can be a form of treatment, which found that plasma exchange can be used to minimise the effects of immune antibodies which lead to the development of GN (Casian 2011).Current novel methods being researched, investigate pathological mechanisms of GN, to possibly produce a drug to reverse this mec hanism. One interesting study set that the voltage-gated potassium channel, Kv1.3 was found in the glomeruli and tubules of rats, with GN (Hyodo et al. 2010).They suggest that Kv1.3 targets and restrain memory T cells, which act like an immune response by recognising foreign bodies (Hyodo et al. 2010). After using a Kv1.3 blocker drug, they found that the rats produced less proteinuria and their glomeruli had less scarring (Hyodo et al. 2010). The study concluded that this Kv1.3 could be the cause of GN and could be a useful finding to heighten a cure for GN in humans, which is still being investigated (Hyodo et al. 2010).Another study suggested that kidney disease may be linked with bone morphogenetic proteins (BMPs), which are growth factors that are important in the regulation on kidney function (Suh et al. 2011). As they interact with binding sites found in the epithelial cells, this study investigated whether polymorphism of the gene for BMP, may play a role in GN (Suh et al. 2011). The study concluded that mutations in this gene may cause children to become susceptible to IgA nephropathy, which is currently being investigated and could mean a possible treatment mechanism (Suh et al. 2011).One other study investigated the presence of myleoperoxidase-associated anti-neutrophil cytoplasmic antibody (MPO-ANCA) and anti-glomerular basement antibodies (anti-GBM Ab) as a possible cause of the crescent shaped scars in rapid progressive GN (RPGM), but this is also still being investigated (Nakabayashi et al. 2011).To conclude GM, is a diverse renal disease, which can be acute or chronic in terms of its causes and consequences. The disease is still being thoroughly investigated today as no definite treatment has been found. vocalize count 1.498

Galileo Galileis Theory Of The Tides Philosophy Essay

Galileo Galileis Theory Of The Tides Philosophy EssayGalileo Galileis theory of how and why the tides worked was, as we have known for hundreds of years, horribly wrong, and yet phenomenal one that exclusively a mind as brilliant as his could have formulate. In fact, it was a significant step towards modern intelligence and discovery. In 1595, when Galileo first came up with his explanations for the tides, he was desperately trying to bring up that the of import universe was true something that the church and public would not accept at the time. In addition to this, Galileo believed that the habitual hypothesis of the cause of the tides at that time (that they were caused by the moonlight) was a lamentable piece of mysticism, as scientists who proposed it could say no scientific explanation for it (Tyson, P. His Big Mistake, http//www.pbs.org/wgbh/nova/galileo/mistake.html). ane of the main scientists of the time who back up the hypothesis of the tides being caused by the moon was Johannes Kepler, who was indeed correct in his hypothesis, which how of all time was only based upon intuition. Interestingly, it is this instruction of conducting science which Galileo opposed he believed in a more hands-on approach to science, in which one worked with what he could see and made rational and numeral hotshot of his conclusions. It is because of this experimental attitude towards science that Galileo was called the father of modern science by the likes of Albert Einstein and Steven Hawking.At the time of Galileo Galilei, modern science did not exist theories were formulated more mere intuition rather than hard facts and observations. Galileo supported the observations made by Copernicus in the mid 16th century which suggested that the undercoat was not static, plainly rather that it orbited nearly the sun, as with other planets. This theory explained why objects in the sky seemed to move. However, at the time of Galileo (16-17th century) the Ptolemaic system was still taught and fully supported by the church. This system described that the sun orbited around a static Earth, in contrast with the Copernican heliocentric view of our system. Therefore, Galileos determination to prove the Copernican theory he so strongly believed in played a large part in why he got the tides wrong.Galileos explanation of the tides was written in a formal garner to a cardinal, after Galileo had failed to convince the church to not ban the Copernican theory in Rome in 1616. This letter was entitled Discorso sul flusso e il reflusso del m atomic number 18. The scientist used an interesting metaphor to describe the tides he examined in how many different ways the water in a vase can move, in which clearly the vase represented the Earth. Firstly, the slope of the vase plays a part in the movement of the water. Furthermore, external forces such as wind can instill water movement. Lastly, and most importantly, the motion of the vase itself can influence the water movement. This final point was the root of Galileos theory of the tides. The judgement occurred to him era travelling on a barge that was ferrying fresh water to Venice. (Galileo lived in nearby Padua and often visited Venice.) He noticed that whenever the barges speed or direction altered, the freshwater inside sloshed around accordingly. If the vessel suddenly ground to a halt on a sandbar, for instance, the water pushed up towards the bow then bounced back toward the stern, doing this several times with ever decreasing agitation until it returned to a level state. (Tyson, P. His Big Mistake, http//www.pbs.org/wgbh/nova/galileo/mistake.html).According to the Copernican system, the Earth is affected by two circular motions the annual revolution astir(predicate) the sun and the diurnal rotation. Due to these two motions, at that place is a change in the speed of the Earths rotation every 12 hours, which Galileo explained mathematically and connected this with his obs ervations of the freshwater barge in Venice. Thus, for 12 hours, a point on the earths surface will move eastward, in opposition to the global westward movement of the earth, and for 12 hours it will move westward, in the same direction as the annual motion. The composition of these motions causes on one hand a slackening (due to a entailment of two opposite motions) and on the other hand an acceleration (due to an addition of two motions in the same direction). (Gigli, R. Galileos theory of the tides, http//galileo.rice.edu/sci/observations/tides.html4). Furthermore, he explained that differences in tidal flows argon due to the differences in the physical conformations of the basins in which they flow. (Machamer, P. Galileo Galilei, http//plato.stanford.edu/entries/galileo/). Thus, Galileo thought he had explained the mystery of the tides. Moreover, this theory of his satisfied Galileo because it strongly supported the Copernican universe the movement of the Earth accounts for the tides, and the tides account for the Earths movement, thus suggesting a heliocentric view of our system, which Galileo supported. In 1623 Galileo was brought to the Inquisition for suggesting in his Dialogue that the Copernican view was correct, which shows how determined the scientist was to find proof of the heliocentric universe.At the same time in history, a contemporary scientist of Galileos, Johannus Kepler, argued that the waters attraction to the moon caused the flux and reflux of the sea water, ie the tides. Galileo dismissed this idea of magic attraction between the moon and water, as no one tried to justify it by mathematical or experimental means. Instead, Galileo believed in a mechanical approach, as explained previously, which could be accounted for use mathematics and scientific facts and knowledge. Galileo, therefore, led the scientific world away from an intuitive and deductive approach which was prominent at his time to a modern, experimental way of conducting science, despite being completely wrong about the cause of the tides.Galileos theory, however, was not without its objections, and one can see why many were reluctant to accept it. The main problem was that his theory would call for only one high tide every day, whereas it was known already that there are about two. Galileo dismissed this anomaly as the result of several secondary causes, including the shape of the sea, its depth, and other factors. (Finocchiaro (1989), pp.127-131 and Drake (1953), pp. 432-6). Also, the tidal argument does not directly apportion with the annual motion of the earth about the sun. And at long last, Galileos theory does not suggest anything about the central position of the sun or about the periods of the planets as calculate by Copernicus. (Machamer, P. Galileo Galilei, http//plato.stanford.edu/entries/galileo/). Therefore, Galileos theory about the tides did not completely prove that our system is heliocentric, even though the scientist was so eag er to do so. It was this eagerness, according to Einstein, that led Galileo to bond so tightly to his theory of the tides, and thus slightly mislead him.Nevertheless, the weaknesses present in Galileo Galileis theory of the tides proved that it had been extremely well thought out and rationalised using mathematics, as one would not be able to point out mistakes if the theory had been based on intuition. On the other hand, Kepler was basing his theory of the tides caused by the moon on pure intuitive deduction. He wrote If the earth ceased to attract the waters of the sea, the seas would rise and flow into the moon and added If the irresistible force of the moon reaches down to the earth, it follows that the attractive force of the earth, all the more, extends to the moon and even farther (Fowler, M. More Kepler, http//galileoandeinstein.physics.virginia.edu/1995/lectures/morekepl.html), which were interesting arguments indeed, but Kepler did nothing in terms of physical and mathem atical illustration to prove his point. Therefore, Galileo had no choice but to refuse Keplers ideas, despite them being ultimately indicative of the truth, due to the lack of empirical and experimental justification. How could the moon be as if by magic attracting the water on the Earths surface? Newtonian gravity did not exist at the time, so an explanation was not possible. What Galileo stood against was the fact that Kepler could not even offer any plausible explanation, in words or mathematics alike, for his theory of the tides. It is this attitude towards science which made Galileo special and earned him a place as one of the greatest scientists of all time.It wasnt until Isaac Newton came along that the tides were explained specifically in a scientific manner. Published in 1686, his explanation of the tides was roughly the following Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. T he gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon (and away from the water on the far side). Since the earth is rotating while this is happening, two tides occur each day (Col, J. Tides, http//www.enchantedlearning.com/subjects/astronomy/moon/Tides.shtml). Newton was thus able to expand on Keplers intuitive theory of the tides and explain it scientifically, finally proving it. This, however, would not have been possible had Galileo not shown the world how to conduct modern science in an empirical and experimental manner, relying on observations to draw plausible, rational and mathematical conclusions.It can hence be concluded that Galileo Galileis mistaken theory of the tides, his greatest blunder, served only to further demonstrate his great strength, which was the ability to conduct scientific experiments and analytic thinking using on ly what he saw with his own eyes, deviating away from intuitive and deductive reasoning to a more hands on, empirical and experimental way of doing science. The world at Galileos time, in the 16-17th centuries, was stuck in a mentality where scientific knowledge was based on more on closing ones eyes than on observing through the telescope (Gigli, R. Galileos theory of the tides, http//galileo.rice.edu/sci/observations/tides.html4), which means that Galileo broke a seemingly unbreakable barrier he fought against the Inquisition, the church and even fellow scientists to bring science to its right direction to en undisputable the future of modern science. It was as if Galileo knew exactly where the world of science was supposed to go, and did everything in his power to make sure it go there. It is of no historical importance that Galileos theory of the tides was actually wrong what matters is the thinking and reasoning process that was behind the very plausible theory for its time. In fact, Newtons proof that it was wrong only again goes to show exactly what Galileo Galilei so strongly stood for basing theories on experimental observations and mathematical calculations using only facts. It is no wonder that the likes of Albert Einstein and Steven Hawking have named Galileo Galilei the father of modern science.

Child Abuse and its Prevalence in Modern SocietyIn our day and advance when people are busy financial backing their everyday lives, a kid is be convoluted behind a closed door. According to Bryan Calo, supervisor of tyke protective services, Child abuse is if a shavers physical, mental, or emotional condition is impaired. The childs basic needs are not creation met, and they are not being provided a safe environment to live in (Telephone Interview). Most often children that are abused, whether it is physical, sexual, emotional, or neglect abuse, leave behind keep their home lives to themselves. This is not because the child is embarrassed but usu every last(predicate)y because he or she is frightened of how the abuser will react toward him or her. Although it is not often shared with friends and even separate family members, so it is still not being taken into consideration that it does exist. Unfortunately, child abuse is a real accompaniment that happens every day. Child ren are being beaten, being sexually abused, being spoken poorly too, not being given daily needs, and being rejected by a parent or defender all the time. Todays golf-club should be more aware of child abuse because when a place is reported it helps benefit the child that is torture by placing him or her in a safer environment (Telephone Interview). (PP) Being able to recognize physical, behavioral, and mental indicators are slipway in which forthwiths society lowlife help prevent child abuse from happening to children all throughout the world.Physical abuse moldiness be prevented in todays society because children deserve to be in a safe environment.

Most often children that are abused, whether it is physical, sexual, emotional, or neglect abuse, will keep their home lives to themselves.

The Quakers and Arts in Utopian Societies :: Essays Papers

The Quakers and Arts in Utopian SocietiesToday, we can still find many examples of past utopias. A utopia is an ideally perfect place, peculiarly in its social, political, moral and legal aspects.1 They do not approve of any actions that are superficial and unnecessary. In addition to these beliefs, people from utopian societies are brawny believers in God. Sharing many of these same ideals, the Quakers are a group with a strong faith. Despite the fact that Quakers feel art is a luxuriousness and a frivolous thing that they should not take part in, many great artists and writers are members of the Quaker society. George Fox shewed the Quakers also known as the hunting lodge of Friends in 1650. This was a time of religious turmoil in England due to people searching for an uncorrupted version of Christianity. For their form of religion, the Quakers relied primarily on sacred searching done by individual members, congregations and meetings. The Quakers were mainly involved in hum anitarian work, seeing the good in everything. They sought to practice total Christianity, with their main opposition toward slavery. During the civil war, the Quakers took the will in the abolitionist movement and in running the Underground Railroad, which aided runaway slaves.2 In 1671, William Penn, a drawing card of the group, worked solely on expanding the Quakers and joining them with other groups.3 Fox developed the idea of Inner Light. This is found within each person, and is a divine inspiration that brings joy and an enlightened conscience. It is Gods spirit found in every human soul. Fox felt that following the inward light would lead to spiritual development and towards individual perfection. He taught the members to worship in silence and people only spoke when they felt moved by the Holy timber when they were in their meetings. George Fox promoted simple living he was against alcohol, holidays, sports, theater, and jewelry. They thought of themselves as friends of Jesus and later, the Quakers also became known as the Society of Friends.4 The Quakers have been associated with the color gray, or drab, because of the simple living that they remain faithful to. Drab is a color that is a mixture of yellow and gray, or a dull light brown. The Friends found colors to be a distraction, using gray to avoid the excitement that was looked down upon. This was also used to keep the divine inspiration within themselves.

The Necessity of Positive and Normative Economics :: essays papers

The Necessity of Positive and Normative Economics Keynes once wrote The object of a positive science is the establishment of uniformities, of a normative science the determination of ideals. (Blaug, 122) This is the dichotomy that economists recognize when approaching their field of study. The complaisant scientist must recognize some(prenominal) positive and normative distinctions, means and ends, as important factors of fruitful research. Secondly, they must clearly express the conditions and assumption which theories holds in order for economics to be utilizable for society. Positive science is that which is a fact of nature or a fact by definition. In mathematics this is the difference between the knowledge that the angles of a triangle sum to 180 degrees, and the definition of a triangle as a two dimensional polygon with 3 sides. In economics, such facts of knowledge include that money is a store of value, or facts of definition that the UNs Human Development Index ranks Canada above Mexico. These are all positive facts. Whether they bank or are associated with values does not reduce their factualness to a normative realm. One cannot refute positive statements by claiming they are arrived at delinquent to values. It is up to normative science to judge the value of the HDI, a positive fact, and not mistake this action as denying the existence of the HDI. This is probably better verbalize with a topic from macroeconomics. Suppose that some economists agree that inflation produces the social cost of having to adjust prices to new levels. This is a completely positive statement. As pertinacious as every term has been clearly defined, one can understand the relation between inflation (as defined) and cost (as defined). Yes, the definitions have been chosen based on specific values, but this does not disaffirm the statement as a true reflection of reality. Suppose we make a true statement which denies that inflation produces this social cos t, by defining inflation or the cost differently. The old positive fact of reality that the first statement asserted has not changed. By changing definitions, we have merely created a new positive statement. A statement is a true positive fact, according to Weston, when it is consistent with definitions and axioms that define the system. We are not necessarily saying anything about what is true outside of that system.
