Natural sciences Essay Knowledge involves acquaintance with truth, principles or facts as with a certain subject or a branch of learning. People have various perceptive of knowledge. There are those who belief that knowledge is found in many forms which must be proven with evidence. It is possible to doubt everything that exist because it is a misconception or it may be seen as an illusion. Doubt is important in knowledge because learning through from the senses or through the senses can be deceptive. For example, senses can deceive because one may smell something sweet and senses deceive that it is going to have sweet taste. However, this is wrong because not everything that smells sweet taste sweet. Dreams are also deceptive as they are just false delusions because occasionally when one is asleep one is deceived by the illusions in dreams. These are just ways that knowledge through the senses can deceive. Therefore, it becomes necessary to doubt everything so that one can get the true knowledge. So as the proverb hold doubt is key to knowledge. Knowledge creates doubt and doubt pave way for gaining more knowledge. If its is not for doubt then there would be no knowledge or the knowledge that would be available would be one that is not complete knowledge (Urdahl, pg 27-29). In natural sciences, scientists have a lot of experience with doubt and uncertainty. This is experience that is very necessary in gaining knowledge in natural sciences. When one does not know the answer to a problem then this can be termed as ignorance. Then one has a hunch as to what the results are, for example, of an experiment, then it means that one has uncertainty. When one is darned sure of what the result would be then it means that one has some doubt. Therefore, it is paramount important that in order to have progress it is important to recognize the ignorance we have in natural sciences and leave room for doubt. This is because scientific knowledge is a body of statements, which have varying degrees of certainty. The degrees vary from being unsure, nearly sure and none absolutely certain. Doubt is a good thing in natural science because if one knows the answer or thinks that one knows the answer then it becomes easy to fail to seek more knowledge about that particular subject. Doubt helps to come out of that emotional attachment that people have in certain beliefs or from the theory of determinism. Example of areas where doubt has assisted in gaining and verifying knowledge is in the assumptions in relativity that inertial mass and gravitational mass are equal. In order to show that they are not the model has to be revised. Scientists have engaged in refining their ability to measure the two. It is the doubt that has developed in this area that has made the scientist revise this model until they have realized that inertial mass and gravitational mass are different at finer degrees. Therefore, they doubt has made it known that the two are not equivalent as has been held in the past. In this case, it is not that the same experiment is repeated but the real key to this is to look at the statements and test if they have been examined to the extent that they should. Doubt allow the use of new tools in scientific experiments which allow new discoveries which do away with the old ideas or theories. Science in this case becomes a process of doubt. Natural scientists are always nor sure and this is the reason as to why they repeat the steps in experiments in order to make sure that it is right. Another area where doubt has necessitated growth of knowledge is in the evolution theory. At the beginning people had strong belief that creation theory was the one that provided call the knowledge about the evolution of human being. However, as knowledge grew people started to doubt some aspects of the evolution theory and developed other theories such as the Darwinian theory of evolution. This is a theory which resulted out f the doubts about some of the aspects of the former theory. This is not the end theory because doubts in some aspects of the evolutions theory have also led to development of some other theories (Axtell pg 87-88). Doubt has also contributed to increased knowledge in other areas, for example, in social science and history. There are two areas that information collected or knowledge gained depends on research or theories which were constructed in the past by various scholars. However it becomes tricky to use such kind of theories to their full because history and social sciences are dynamic. For example, the society change as time moves. Therefore, this is also in the same way that the theories are supposed to change. For example, if theories that were constructed in the fourteenth century are used in the twenty first century then there is no doubt that the theory would contain a lot of faults because of the changes that have occurred in the society. People have developed in their way of reasoning as in these days there are more sources of information than in the past. Reason is one part of gaining knowledge that enhances the development of doubt. This is because it is after deductive reasoning that a person is able to develop hypothesis that proves some knowledge as relevant or irrelevant (Gotschl, pg179-180). Historians do their research and base most of their research on the researches that were conducted in the past. The information in the research where they base their research would be biased or exaggerated. This is what cause doubt and enhance new research to be conducted regarding some issues. Despite the fact that some people are emotionally attached to some believes doubt has made them to relent some of their believes. For example, different ethnic groups have their own myths about where they originated or who is their god or where their god lived. In traditional society people had strong emotional attachment to these beliefs (Chang pg 581). However, as time has passed people have developed doubt about these believes to develop other believes. This is because most of the beliefs in the traditions are not well reasoned and are also biased to particular ethnic people. People have developed other believes that are more inclusive of other ethnic groups all over the world. This has risen out of the doubt that people have some of the things that happened in the past (Lamm Norman pg 11-12). Despite that knowledge plays a key role in knowledge I think that knowledge or truth is a fixed situation because truth is not questionable. So if true knowledge is out there to be discovered or to be learned then it means that when we know or acquire knowledge then there should be no room for doubt. I also think that knowledge depends mostly on human perception. Natural sciences have more upper hands in investigating the truth. However these sciences are still subjected tout human brains. Curiosity is also key to knowledge rather than doubt. Human beings are always curious to know more about their nature. The curiosity allows them to make discoveries and also strive to find the truth. Looking critically at the discoveries that have been made in the past it is out of curiosity that this has happened. This curiosity leads to knowledge, which then leads to wisdom. Doubts make us to know hat our knowledge is correct instead on believing in something blindly. However I do not feel that doubt makes us to make any discovery or learn anything that is new to us. It is curiosity that allows us to acquire new knowledge more quickly. Work cited Axtell Guy. Knowledge, belief, and character: readings in virtue epistemology, 1st edition, Rowman Littlefield, 2000.

Trade-studies are used to figure out the best possible approach. Trade studies functions includes improving a particular aspect of the system design to figure out the best approach to be used given a well-defined set of technical choices and parameters [1]. The inputs of the trade study are the DDP of competing technical solutions or just one widely variable solution. These inputs can consist of models of those technical solutions, the stakeholder’s priority ranked operational requirements, system life-cycle considerations, and other data. The output of a trade-study is a decision on which technical route to follow based on the desired characteristics of the system within the alternatives being studied. The trade-study will also document the justification of the decision. The goal of this section is to explain the process that provides the trade study its justifying power, a little more detail on those inputs and outputs, when and how many trade studies are conducted, what t he sensitivity analyses are, and how alternatives are analyzed are related to trade-studies.

General Safety and Security Essay

* Investment in surveillance camera systems by school districts ensures parents and guardians that the general safety and security of children are being addressed during schools hours and at all after-school extracurricular activities and programs. 2. Crime Deterrent * The presence of highly visible surveillance cameras at strategic locations in buildings and public areas/premises of a school property prevents theft, vandalism and acts as a deterrent to thieves and criminals from indulging in illegal activities. 3. Sexual Predators * One of the biggest threats that school children face is the threat of sexual predators and pedophiles hanging around unobtrusively on school campuses or in parking lots. Camera systems’ footage is very useful in tracking down predators or helping inform police about threatening situations in real time. 4. Prevent Bullying * New-generation surveillance camera systems have audio, voice and sound capturing capabilities. Teenagers bullying or harassing other students can be disciplined based on video and audio footage records. 5. Emergency Evacuation * School security personnel manning surveillance camera systems in real-time can take quick action about evacuating children, faculty and staff in case of emergencies related to fire or other potentially dangerous situations. Prevent Theft and Illegal Activities * The primary purpose of installing surveillance cameras is to act as deterrence to robbers, criminals, petty thieves and unscrupulous elements from indulging in theft, illicit and criminal activities. Security cameras are installed in bungalows, townhouses, apartment buildings, condominiums, schools, university campuses, offices, stores, malls and other public areas. These cameras monitor suspicious activities; stop theft, vandalism and shoplifting; and alert stationed security officers about real-time thefts. Staff monitoring cameras and centrally manned systems in large businesses can also inform county and state law enforcement officials about developing dangerous situations.

The Failed State of Franklin

Founded in 1784 with the intent of becoming the fourteenth state of the new United States, the State of Franklin was located in what is now Eastern Tennessee. The story of Franklin — and how it failed — highlights how the victorious end of the American Revolution in 1783 actually left the new Union of states in a fragile condition. How Franklin Came to Be The costs of fighting the Revolutionary War left the Continental Congress facing a staggering debt. In April 1784, the legislature of North Carolina voted to give Congress some 29 million acres of land — about twice the size of Rhode Island — located between the Appalachian Mountains and the Mississippi River to help pay its share of the war debt.   However, North Carolina’s â€Å"gift† of the land came with a major catch. The cession document gave the federal government two years to accept complete responsibility for the area. This meant that during the two-year delay, the western frontier settlements of North Carolina would be virtually alone in protecting themselves from the Cherokee Indians, many of whom remained at war with the new nation. Needless to say, this did not sit well with the residents of the ceded region who feared that the cash-starved and war-weary Congress might even sell the territory to France or Spain. Rather than risk this outcome, North Carolina took the land back and began to organize it as four counties within the state. After the war, the frontier settlements west of the Appalachian Mountains and east of the Mississippi had not automatically become part of the United States. As historian Jason Farr wrote in the Tennessee Historical Quarterly, â€Å"It was never assumed.† Instead, Congress gave the communities three options: become parts of existing states, form new states of the union, or become their own sovereign nations. Rather than choosing to become a part of North Carolina, the residents of the four ceded counties voted to form a new, fourteenth state, which would be  called Franklin. Historians suggest that to some extent, they may have agreed with George Washington, who suggested that they had become â€Å"a distinct people† with cultural and political differences from those in the Atlantic states who had fought for American independence. In December 1784, Franklin officially declared itself to be an independent state, with Revolutionary War veteran John Sevier reluctantly serving as its first governor. However, as historian George W. Troxler notes in the Encyclopedia of North Carolina, Franklin’s organizers did not know at the time that North Carolina had decided to take it back. â€Å"The December 1784 constitution of Franklin did not formally define its boundaries,† Troxler wrote. â€Å"By implication, jurisdiction was assumed over all of the ceded territory, and area approximating the future state of Tennessee.† The relationship between the new Union, its 13 Atlantic Seaboard states, and the western frontier territories had gotten off to a rocky start, to say the least. â€Å"There was little concern for western political and economic interests during the Confederation era, especially among the northeastern elite,† Farr writes. â€Å"Some even assumed that frontier communities would remain outside the union.† Indeed, Franklin’s declaration of statehood in 1784 stirred fears among the Founding Fathers that they might not be able to keep the new nation together.   The Rise of Franklin A delegation from Franklin officially submitted its petition for statehood to Congress on May 16, 1785. Unlike the statehood approval process established by the U.S. Constitution, the Articles of Confederation in effect at the time required that new petitions for statehood be approved by the legislatures of two-thirds of the existing states. While seven states eventually voted to admit the territory as what would have been the 14th federal state, the vote fell short short of the required two-thirds majority. Going It Alone With its petition for statehood defeated and still unable to agree with North Carolina over several issues including taxation and protection, Franklin began operating as unrecognized, independent republic. In December 1785, Franklin’s de-facto legislature adopted its own constitution, known as the Holston Constitution, which closely tracked that of North Carolina.    Still unchecked — or perhaps unnoticed due to its isolated location — by the federal government, Franklin created courts, annexed new counties, assessed taxes, and negotiated several treaties with area Indian tribes. While its economy was based mainly on bartering, Franklin accepted all federal and foreign currencies. Due to the lack of its own currency or economic infrastructure and the fact that its legislature had granted all of its citizens a two-year reprieve on paying taxes, Franklin’s ability to develop and provide government services was limited. The Beginning of the End The ties that  held Franklin’s unofficial statehood together  began to unravel in  1787. In late 1786, North Carolina offered to waive all back taxes owed to it by Franklin’s citizens if the â€Å"state† agreed to reunite with its government. While Franklin’s voters rejected the offer in early 1787, several influential citizens who felt disenchanted by the lack of government services or military protection in Franklin supported it the offer. Ultimately, the offer was rejected. North Carolina subsequently sent troops led by Col. John Tipton into the disputed territory and began to re-establish its own government. For several very contentious and confusing months, the governments of Franklin and North Carolina competed side-by-side.   The Battle of Franklin Despite the objections of North Carolina, the â€Å"Franklinites† continued to expand to the west by forcibly seizing land from the Native American populations. Led by the Chickamauga and Chickasaw tribes, the Native Americans fought back, conducting their own raids on Franklin’s settlements. As part of the larger Chickamauga Cherokee Wars, the bloody back-and-forth raids continued into 1788. In September 1787, the Franklin legislature met — for what would be the last time. By December 1787, the loyalties of Franklin’s war-weary and debt-laden citizens to its unrecognized government was eroding, with many openly supporting alignment with North Carolina. In early February 1788, North Carolina ordered Washington County Sheriff Jonathan Pugh to seize and sell at auction any property owned by Franklin’s Governor John Sevier in order to repay taxes he owed to North Carolina. Among the â€Å"property† seized by Sheriff Pugh were several slaves, who he took to Col. Tipton’s home and secured in his underground kitchen. On the morning of February 27, 1788, Governor Sevier along with about 100 of his militiamen showed up at Tipton’s house, demanding his slaves. Then, on the snowy morning of February 29, North Carolina Colonel George Maxwell arrived with 100 of his own better-trained and armed regular troops to repel Sevier’s militia. After less than 10 minutes of skirmishing, the so-called â€Å"Battle of Franklin† ended with Sevier and his force withdrawing. According to accounts of the incident, several men on both sides were wounded or captured, and three were killed. The Final Fall of Franklin The final nail in Franklin’s coffin was driven in March 1788 when the Chickamauga, Chickasaw, and several other tribes joined in coordinated attacks on frontier settlements in Franklin. Desperate to raise a viable army, Governor Sevier arranged for a loan from the government of Spain. However, the agreement required Franklin to be placed under Spanish rule. To North Carolina, that was the final deal-breaker. Strongly opposed to allowing a foreign government to control what it considered to be part of its state, North Carolina officials arrested Governor Sevier in August 1788. While his supporters quickly freed him from the poorly protected local jail, Sevier soon turned himself in. Franklin met its final end in February 1789, when Sevier and his few remaining loyalists signed oaths of allegiance to North Carolina. By the end of 1789, all of the lands that had been part of the â€Å"Lost State† rejoined North Carolina. The Legacy of Franklin While Franklin’s existence as an independent state lasted less than five years, its failed rebellion contributed to the framers decision to include a clause in the U.S. Constitution regarding the formation of new states. The â€Å"New States† clause in Article IV, Section 3, stipulates that while new states â€Å"may be admitted by the Congress into this Union,† it further stipulates that no new states â€Å"may be formed â€Å"within the jurisdiction of any other State† or parts of states unless approved by votes of the state legislatures and the U.S. Congress.
