SOUNDOFF--A Computer For All Students--Revisited Essays

SOUNDOFF--A Computer for All Students--Revisited The introduction of the graphing calculator has changed the structure of teaching and learning mathematics. This made it possible for everybody to receive the benefits of a computer-generated visualization without the high cost of a computer. These graphing calculators over the years have lowered in cost, became easier to use, and are more portable. The next generation of graphing computers has arrived with the recent introduction of the Texas Instrument TI-92. This relative inexpensive calculator will allow more high school teachers to teach an area mostly untouched, computer symbolic algebra and computer interactive geometry, because it has not been practical or possible. The TI-92 is merely the beginning of the new revolution of hand-held computing tools. The next challenge mathematics teachers are facing is the teaching of traditional paper-and-pencil symbolic algebra skills. This task has been made obsolete by the more accurate and faster computer symbolic algebra algorithms. Students can get a far better illustration of important concepts and applications of mathematics with these new hand-held tools than with the traditional paper-and-pencil task. The paper-and-pencil task and other traditional skills must still be acquired, but students should spend less time acquiring it. More emphasize must be put on computing tools. Students should take advantage of the computer technology to become powerful and thoughtful "problem solvers." The process of changing from traditional methods to a more computer-oriented environment has to be met by the education and mathematics community. Educators should have textbooks that better represents the new technology. Teachers need to be more technology literate. The mathematics community must dispel the image of "doing mathematics" with the traditional paper-and-pencil method. These reforms can better teach students important skills needed for the future. The use of technology in mathematics will give students an advantage mathematics and related technology. Students will need that advantage if they wish to compete in the twenty-first century. Opinion This article stressed very important issues educators, teachers, and the mathematics community must face. The reform will change the course of mathematics in school and elsewhere. As a student, I am very concern about the future of mathematics. My future plans will revolve around mathematics and technology. I understand the need to continue using the paper-and-pencil methods, but computing tools should be added to the current criteria. The future will be technologically intense and very competitive. Graphing calculators has enhanced mathematics and I think the new powerful computing tools will do the same for the next generation. These hand-held computers are inexpensive and contain very powerful and versatile computer software. This could be the computer for all mathematics students.

Science constantly changes the way we understand the world. 2. Energy conversions underlie all ecological processes. Energy cannot be created; it must come from somewhere. As energy flows through systems, at each step more of it becomes unusable. 3. The Earth itself is one interconnected system. Natural systems change over time and space. Biogeochemical systems vary

IS PROPAGADA A TECHNIQUE OR A PHENOMENON Essay Example | Topics and Well Written Essays - 1000 words

IS PROPAGADA A TECHNIQUE OR A PHENOMENON - Essay Example on, the analysis will seek to determine whether or not the presence of propaganda throughout the modern world is merely something that exists naturally or whether or not it is an purposeful and authored process. Firstly, it should be understood that the nature and definition of propaganda itself lends the reader to assume that the process of information distribution and purposeful deception is not something that merely â€Å"happens†. 1 Of course there are many instances throughout the world in which incomplete information is transmitted to the media participant; however, these inadvertent instances do not accurately define the conventional definition of â€Å"propaganda†. Ultimately, the use of propaganda, by its very definition and nature, is to deceive or mislead the media participant to understand the world or a particular situation within a given construct or manner. As such, it is painfully obvious that the majority of propaganda that exists is most certainly a technique by which entities, individuals, or governments attempt sway the opinions of societal stakeholders. Therefore, the reader can adequately assume that the types of â€Å"propaganda† under discussion is more likely than not an authored process that is intended to be misleading, untrue, or inaccurate.2 As with a legal discussion of motive, the question that has thus far been represented ultimately reduces to the intention of the way the information is represented. In the event that a particular entity, government, or individual represents information in a willfully deceitful manner as a means of swaying individual opinions, then it is clear and apparent that the process is a technique which is engaged as a means of effecting a particular goal.3 Yet, in the event that incomplete, untrue, or inaccurate information is represented to a group or an audience with no intention to deceive or mislead, then it cannot be said that such a process is propaganda; rather, it is an inadvertent process that

Nature of an electron Coursework Example | Topics and Well Written Essays - 2250 words

Nature of an electron - Coursework Example This is described in a classical wave model of light; which states that light properties that are similar to any wave. For instance, light experiences reflection and refraction in the same manner that any other wave would experience interference. In addition, light experiences the Doppler effect the same way any other wave would experience Doppler effect. However, the prediction of the quantum model shows that frequency or wavelength of the incident of the incident light only affects the photoelectric current. where E- is the energy that the quantum light produces, Kmax is the maximum kinetic energy of the photoelectrom emitted , where as Wo is the work function of the of the energy needed to innitiate the emision of photoelectrons from the metal surface. In an experiment to demonstrate the photoelectric effect, the following apparatus are required: a digital voltmeter to be used to measure the reverse voltage reading, a photodiode connected with an amplifier, monochromatic light sou rce to produce light beams to irradiate the photo cathode, and a filter to neutrally vary the intensity of light. Generally the quantization energy of the electromagnetic radiation in light is given in the relation, where the radiation energy, is a constant known as the Plank’s constant and is given as (6.63?10^-34Js), and - is the frequency of the light incident energy. The validity of the equation is based on the photoelectric effect experiment. There are four aspects that need to be taken into consideration when conducting the photoelectric effect experiment. These facts include: the minimum frequency; when the frequency of the incident light is less than the minimum frequency required, no photoelectrons can be emitted despite the intensity of the light. The value of minimum frequency varies from metal to metal. Secondly, as the frequency of the incident light increases, the kinetic energy of the photoelectrons increases. However, the intensity of the light is independent of the kinetic energy of the electron emitted. And lastly, the emission of photons is effectively instantaneous. (physics 242 laboratory manual) The photoelectric effect experiment consists if a high intensity lamb, a phototube, and batteries. The photodiode tube is the central element of the apparatus. The window in the diode gives way for light into the tube to the clean metal surface at the cathode. The diode is completely evacuated to avoid any collision of air molecules and the electrons. When beams of light hit the surface of the metal plate at the cathode, electrons are emitted by the metal plate. The photodiode has an in-built capacitance developing a voltage during the charging process by the electrons emitted. When the stopping potential of the cathode is reached, the difference in voltage across the two poles, that is, cathode and anode stabilizes. A very sensitive amplifier is used to measure the stopping potential. The amplifier aids in the establishment of the small nu mber of photoelectrons emitted. A voltmeter is used to measure the output voltage of the between the batteries and the output ground terminals. A number of different monochromatic light beams are used for the experiment. A glass tube consisting of mercury vapor produces light when discharged electrically. The glasses envelop filters out the ultraviolet light that can be harmful. The mercury light produces five thin spectral lines that are: yellow, green blue, violet, and ultraviolet in the visible region. These lines can be spatially separated by diffraction. The wavelength desired is selected using a collimator, and the intensity of the selected wavelength is varied using a density filter The mercury lamb is switched on. On the front reflective mask of the lamb box, yellow, green, and tiny rays of blue

Freedom of speech Essay Introduction: The American Flag is slowly being folded into a perfect triangle by soldiers. Bystanders watch as a twenty one gun salute is given to a veteran’s family who gave his life for our country. The family weeps over their lost loved one. This sacred moment in time is one that no one should interrupt. A group out of Kansas known as Westboro Baptist Church (WBC) travels around the country protesting at soldiers’ funerals that the death is God’s punishment to the U. S. for tolerating homosexuality in the country. This so called â€Å"church† is able to hold protests due to constitutional rights and express their freedom of speech; however they should not be allowed to protest at funerals out of respect for the deceased and disturbing the peace. The Westboro Baptist Church is disturbing the public’s peace, but still has the freedom of speech to picket and protest what they please. Funerals should be sacred, and therefore Congress should pass a law placing limits on where it is acceptable to protest. Research Section: The Brief Bio of Pastor Fred Phelps states, in Topeka, Kansas, Fred Phelps founded the Westboro Baptist Church in 1955. Phelps was appointed to the United States Military Academy at West Point, but instead enrolled for Bible/Ministerial training at Bob Jones College. Joined by his family and friends, Phelps is still leading the church today. The Westboro Baptist Church is a non – profit organization, and the church considers itself an â€Å"Old School† Baptist Church. The Westboro Church groups are traveling around the country making stops several times a week to protest and picket. â€Å"Targets include schools the group deems to be accepting of homosexuality; Catholic, Lutheran, and other Christian denominations that WBC feels are heretical; and funerals for people murdered or killed in accidents like plane crashes and for American soldiers killed in Iraq and Afghanistan, a tactic the group started in 2005† (The Anti-Defamation League). Not only directed at soldiers and gays, The Westboro Baptist Church fuels on any tragedy happening in the United States. After the natural disaster of hurricane Sandy, the church protests that it was a sign from God. The Constitution, under the Bill of Rights, protects this groups’ advocacy to protest wherever they wish. The church holds signs saying â€Å"Pope in hell†, â€Å"Thanks God for dead soldiers†, â€Å"God Hates Fags† and anything else to offend the people or groups it is towards. They also wear American flags around their waste and will kick it around on the ground. The community cannot endure the verbal torture any long and this has led to court cases and out breaks. Jonsson states â€Å"While Westboro is usually careful to stay within the law and clear protests with local police, counter protesters have in the past attacked members of the group, even pouring coffee on them and spitting on them.† Argument: The Westboro Church should not be able to disturb the peace and privacy at a funeral nor picket institutions or individuals for supporting homosexuality. The signs they display are disturbing, inappropriate, and offensive. The Westboro Church’s controversial appearances have led to several court cases dealing with places restrictions on the freedom to protest, particularly distance limits on how close you are authorized to protest from a funeral site. One case was brought forward by Albert Snyder, father of Mathew Snyder, a 20 year-old solider killed in Iraq. Ariane de Vogue stated â€Å"The case, one of the most controversial on the court docket, was brought by Albert Snyder, who sued the church, after members picketed the funeral of his son, Lance Corporal Matthew Snyder, who died in Iraq†. The Church has many opinions that should not be said or displayed to the public due to the emotional cause and pain the public has to endure. Having hurt the American citizens, the Westboro Church, under the first amendment, has the freedom of speech. The First Amendment states Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. Therefore, this gives the Westboro Baptist Church the right to protest in public while being protected by federal law. The Church groups were standing far enough away from the funeral that the court could not prove the protest was exactly pointed at the Snyder’s son’s burial. Warren Richey stated â€Å"The protesters stood in a cordoned off area approved by police about a thousand feet from the church.† The Supreme Court used the distance the group was away from the burial to say that the protest was not pointed directly at Snyder’s family during the burial. Even though The Westboro Church has the First Amendment protecting them, they are still disturbing the peace and offending the public by protesting. Our freedom of speech is protected by the Constitution which is protected by our soldiers, a freedom Westboro Baptist Church has abused by protesting the very soldiers who fight for this freedom. Holding signs saying â€Å"you’re going to hell†, â€Å"God hates America†, and â€Å"Thank God for IEDs†, are insulting to the public and the country and are affecting Americans everywhere. â€Å"Snyder has called the day his son died ‘the worst day of his life’. His grief was compounded, he said, by being targeting by the church’s demonstrations. ‘It is one thing no family should ever have to go through’†(De Vogue, Ariane). The definition of disturbing the peace is â€Å"A person who fights in a public area, or who brings about the threat of fighting, anyone who is purposefully disruptive of an otherwise peaceful public assembly, one who solicits money while in a public place a person who is drunk, and unruly in a public area, or any group that participates in an unlawful assembly† (For the people). Westboro would fall under anyone who is purposefully disruptive of an otherwise peaceful public assembly. The church is showing poor judgment and an utter disregard for human dignity when they protest at a funeral. Proposal: With all the disturbances that the Westboro Baptist Church has caused, Congress should incorporate litigation to prevent insults to others. Congress must pass a law placing limits on the extent of free speech and the right to protest in regard to memorial services. Given the freedom of speech, Congress cannot prohibit the protestors from displaying signs that are obscene or stating their opinions, but can pass a law stating how far away from the funeral the protests have to be. Williams stated, â€Å"Indeed, in the incident in question, Westboro complied with police requests to stay 1,000 feet from the funeral, and all but the tops of its members’ signs were hidden from mourners’ view†. Congress should take this into consideration and reflect upon veterans and American citizens civil rights. In my opinion, family members should not have to face such obscenities during a period of mourning. The First Amendment does not prevent Westboro Baptist Church from offending the family members and citizens from their perverse signs and protests. Therefore, many civil law suits have not proven effective towards the church under the right of the First Amendment and freedom of speech. Most Americans whose thoughts are negative towards the church’s views choose to hold counter protests in support of veteran’s family members who have been killed in combat (Policinski, 2011). Congress passing the law should help these families during a time of grief to remember their loved one, and not have to see the disgraceful sign of hatred to this country. Conclusion: The First Amendment to the Constitution is a privilege Americans take grand ownership of. However, a group of individuals from the Westboro Baptist Church are taking advantage of this right we all have, pushing the freedom of speech to the point where citizens are questioning its true value. Individuals are starting to come together to counter protest toward Westboro so they will stop insulting those that fight for this country. Policinski stated â€Å"A few weeks ago, in Nashville, Tenn., more than 1,000 counter-protesters turned out in support of family members of a soldier killed in combat, overwhelming the presence of a small Westboro contingent†. The daily lives of Americans should not have to be interrupted by such insanity, and having to see vulgar signs shooting down the citizens and their country, also that their nation’s flag is being tossed around like a rag doll. If we fail to police our own responsibilities as citizens, America will shrink back to the oppressed nation it once was. Congress must push to clarify and define what is protected In the Constitution and end this travesty that is disrupting our peace. Works Cited: â€Å"Disturbing The Peace.† For The People.

Ralph Waldo Emerson and Transcendentalism Essay -- Biography Biographi

Ralph Waldo Emerson and Transcendentalism      Ã‚  Ã‚  Ã‚   Ralph Waldo Emerson believed in the potential within every individual to achieve a heightened state of being and awareness through a close observation of the world and an introspective look at himself. Infused in his work are the influences of transcendentalism and his life as a Unitarian pastor. James D. Hart, when discussing the spirit of transcendentalism, states, "Man may fulfill his divine potentialities either through a rapt mystical state, in which the divine is infused into the human, or through coming into contact with the truth, beauty, and goodness embodied in nature and originating in the Over-Soul. Thus occurs the doctrine of correspondence between the tangible world and the human mind, and the identity of moral and physical laws" (Hart 674). This concept is the embodiment of Emerson's sermons and essays, and any one of his works fulfills or inspires a divine potential.    "Self Reliance," published in 1841, is one of Emerson's most influential essays, and its title addresses a central concept of American Transcendentalism. The essay promotes self trust and independence of the individual, and this idea is expressed in the final lines, "Nothing can bring you peace but yourself. Nothing can bring you peace but the triumph of the principal" (Lauter 1638). The principal he refers to is a moral truth that can only be developed in one's own mind. As man lives in search of this truth, he achieves human divinity. "There is a time in every man's education when he arrives at the conviction that envy is ignorance; that imitation is suicide; that he must take... ... and divine because nothing is at last sacred but the integrity of your own mind" (Lauter 1624).    Works Cited    Emerson, Ralph Waldo.

How important are parents in a child’s life? Essay

Parents How important are parents in a child’s life? In my opinion, parents are extremely important in the raising of a child. Without the presence of a parent, a child will have a very difficult time growing up. There are essential things that a child has to be provided with. Those needs, I classified them into three important categories: Love Love is absolutely necessary in a good parent-kid relationship. It helps form stronger and better relationships. Things that parents do out of love will make kids appreciate them more. A lot of times discipline lessons, though sometimes harsh, are included in the â€Å"love package†. Kids may not appreciate this right away, but in the long run they will realize their mistake and they will be thankful for those few slaps across the butt or the face. Most of the time a little discipline is all you need to make sure that kids stay on the right road in life. Support Kids need support in order to survive in the â€Å"real world†. Parents are the only ones that can give them support in the arising of their lives. Kids will need emotional support to face some of the problems earlier in their life, because of sheer lack of experience. Not knowing how to solve some of the life’s problems would only help them get hurt. That’s when the parents play the key role in their life. Parents can talk one-on-one with their children, with patience and understanding. This is very important. When a child needs advice, or needs to open up, it is very important for parents to be wise and understanding. Criticism and getting mad will never bring closeness between a parent and a child. Another example of support is financial. Financial support is something not all parents can give, but if they can do it, then it would really help the kid. When I say financial support I do not mean giving them spending money any time they ask for it. What I mean is more like money for school activities and funds for later  education in their life. This will give them many opportunities as they go through life. It is up to the children to take advantage of those opportunities. Sacrifice Good parents sacrifice many things in order to provide for their kids. Sometimes they will miss an important social event just so that they could stay home and help their kids with the homework or they would get off early from work, despite the managers warning, so that they would be at their kid’s game and cheer them on. Some people would call this sacrifice, but I say they are wrong. It is a good investment in a relationship. Kids will grow up appreciating their parents. I could not imagine a parent-kid relationship without love, in my opinion it would not be a relationship. Kids without support would be like young plants without a pole for support, they would just fall over and dry out. Sacrifice from the parent’s side helps kids realize that there will always be someone at their side when they need them. In conclusion I think that these three categories are a must for a parent.
