Amusement Park Physics :: physics theme park roller coaster

Missing formulas A new era in theme parks and roller coaster design began in 1955 when Disneyland ushered in the new era of amusement park design. Disneyland broke the mold in roller coaster design by straying from the typical norm of wooden roller coasters; thus, the steel tubular roller coaster was born. Disneyland’s Matterhorn was a steel tubular roller coaster with loops and corkscrews, which had never been seen before with the wooden coasters. In addition to the new steel tube roller coaster, the new coaster design also proved to be the most stable, allowing for wilder designs. The first successful inverted roller coaster opened up in 1992, and now it is not uncommon to find passengers of various roller coasters with their feet dangling above or below them as they circumnavigate the track. In 1997 Six Flags Magic Mountain opened a roller coaster, that just a few year previous would have been considered impossible. The Scream Machine is 415 feet tall and takes willing riders on an adrenali ne rush using speeds of 100 miles per hour. Technology working with the laws of physics continues to push the limits of imagination and design. Many people do not realize exactly how a roller coaster works. What you may not realize when you are cruising down the track at over 60 miles per hour, is that the roller coaster does not have a motor or engine. At the beginning of the ride the car is pulled to the top of the first hill where it comes to a momentary halt. At this point its potential energy is at a maximum and the kinetic energy is at a minimum. As the car falls down the hill it is losing potential energy and is gaining kinetic energy. It is this kinetic energy that keeps the car going throughout the remainder of the ride. The conversion of potential energy to kinetic energy is what drives the roller coaster, and all of the kinetic energy you need for the ride is present once the coaster descends the first hill. Once the car is in motion, different types of wheels keep the ride running smooth. Various running wheels help guide the coaster around the track. Friction wheels control lateral motion. A final set of wheels keeps the coaster on the track even if the coaster is inverted. Compressed air brakes are used to stop the coaster as it comes to an end.

Maya Angelou :: Biography Biographies Essays

Maya Angelou "I had decided that St. Louis was a foreign country. In my mind I had only stayed there for a few weeks. As quickly as I understood that I had not reached my home, I sneaked away to Robin's Hood's Forest and the caves of Alley Oop where all reality was unreal and even that changed my day. I carried the same shield that I had used in Stamps: 'I didn't come to stay.'" In Maya Angelou's autobiographical novel, "I Know Why the Caged Bird Sings", tender-hearted Marguerite Johnson, renamed Maya by her refined brother Bailey, discovers all of the splendors and agonies of growing up in a prejudiced, early twentieth century America. Rotating between the slow country life of Stamps, Arkansas and the fast-pace societies in St. Louis, Missouri and San Francisco, California taught Maya several random aspects of life while showing her segregated America from coast to coast. When Maya was three years old, her beautiful and successful mother sent her and Bailey from California to Stamps to stay in the care of their grandmother, Mrs. Annie Henderson. Soon thought of as their real mother, "Momma" raised her grandchildren with the strict Southern principles such as, "wash your feet before you go to bed; always pray to the savior and you shall be forgiven; chores and school come before play; and help those in need and you shall be helped yourself." Bearing those basic principles, Maya and Bailey grew older and wiser in Stamps, each year watching the Negro cotton-pickers come and go with the burdens and homage comparable to no white person in the county. However, one day their father rode extravagantly into Stamps and called for his children to return home with him to St. Louis. Bailey, an adventurer eager to leave the quaint, simple family life in Arkansas, agreed immediately, but "tender-hearted" Maya was frightened by the idea of big cities and strange people. In St. Louis, where she was presented an entirely different lifestyle, Maya experienced harrowing moments that caused her yearning for the quiet safety of Stamps. Her "Mother Dear's" boyfriend, Mr. Freeman, sexually abused her twice, and when she testified in court against him, the "important connections" her mother had to the gangsters in St. Louis beat Mr. Freeman to death to disburden the shame from the family. In court, Maya lied, saying that he only touched her once, and the guilt of lying to her closest friend, her brother Bailey, cause Maya to mute herself.

Sexual Curiosity

Sexual Curiosity Taken from Growing Concerns — A parenting question-and-answer column with Dr. Martha Erickson Question: I've recently started doing child care in my home for several young children and I've observed some sexual curiosity that I'm not quite sure what to make of. Can you provide some guidelines about what is normal for young children and any problem signs that I ought to be aware of? Answer: Sexual curiosity is a natural phenomenon in children of all ages, but it does demand a careful response so that children develop a healthy respect for themselves and others. In general, this is what you might expect for children from infancy through the early school years. Birth to 2 years Babies explore their bodies with their hands, with no shame or sexual meaning attached to the behavior. In little boys, erections are a natural reflex, especially during diapering. Preschool years Young preschoolers are openly curious–asking, looking, touching. They figure out, â€Å"I'm a girl, you're a boy,† and wonder about the similarities and differences. As they begin to discover the shock value with adults, they may use sex words and bathroom humor, often with little or no understanding of the meaning. It is not unusual for preschoolers to use masturbation for self-comfort when they are alone. Elementary school years As sexuality takes on new meaning, elementary aged children become more secretive about exploration (playing doctor with a friend, for example) and gradually become more modest about their bodies. They are curious about romantic and sexual fantasies, but often are vague or confused about details. Although it is normal and healthy to express an interest in sexual things, there are red flags that caregivers should be aware of: Preoccupation with sexual things (e. g. , the child can't seem to stop talking about sexual things). Acting out sexual behavior that involves force or violence. These behaviors suggest the possibility that the child either has been sexually abused or has witnessed explicit sexual behavior or sexual violence at home or elsewhere. Even seeing media images of sex can be very disturbing to children. And when children act out what they see in films or TV, it can set up a dangerous domino effect on other children. As with all aspects of child rearing, it is important that you work in partnership with the parents of children in your care. With regard to sexual curiosity, you and the parents would do well to agree on clear limits about the sexual language and behavior that are acceptable, monitor and regulate the children's exposure to inappropriate television programs and give clear messages about respectful, loving sexuality. And if you suspect that a child in your care has a problem, talk with the parents right away so that they can seek advice from their pediatrician or other professional. Editor's note: Dr. Martha Farrell Erickson, director of the University of Minnesota's Children, Youth and Family Consortium, invites your questions on child rearing for possible inclusion in this column.

Interpretation and delivery of language Essay

I am writing to congratulate you upon being chosen to play the part of Richard in our forthcoming production of Richard III. This letter is a guide for you for how I would like the part of Richard to be acted. This shall be primarily based upon two key scenes in the play, which are Act 1 Scene I (opening scene) and Act 5 Scene VII (eve of battle scene). This guide covers 3 main aspects of playing the part of Richard. These are: Your interaction with other characters, your interpretation and delivery of speech within the play and your physical representation of Richard. The reason why these two scenes have been concentrated on is because they occur at key moments within the play and at opposite ends as well. Not only do they appear at opposite ends of the play but they also occur when Richards’s confidence is at opposite ends of the emotional spectrum. This enables us to see Richard from multiple perspectives and it shows us his multi-faceted mental and emotional states. As I am sure you are aware, Richard is portrayed as an Evil and conscience free king as well as being physically deformed. Although elements of this are based upon the truth, it is appreciated that Shakespeare made many of these descriptions up. Due to limited other historical reference this is how Richard is portrayed nowadays. Shakespeare’s reasons for, perhaps, making up these facts are to please the Queen at his time, who was Queen Elizabeth I. This would please her because it was her grandfather, Henry Tudor (later Henry VII (Richmond in the play)), who became King after Richard III was killed in battle. Obviously this made Richmond and Richard enemies, so portraying Richard as both evil and deformed would put Queen Elizabeth and her ancestry in better light. Richards’s evil is very evident from his very first speech (a soliloquy) in the first scene of Act 1. This solo speech to the audience sets the tone for the nature of Richards’s evil worlds and actions throughout the rest of the play. This supreme malignity is evident in the quote’†¦ that I will shortly send thy soul to heaven,’ when referring to his Brother Clarence who he has sworn to save from imprisonment. This is remorseless in its extreme form considering that he has pledged to his brother to have him released form the Tower, which Clarence believes, but in truth he is going to have him killed. This means you must portray an immense feeling of evil and remorselessness to the audience. This could be done by snarling and almost spitting when speaking of what you plan to have done as well as making angular and jerky motions rather than smooth rounded ones. However Richards’s evil is often matched by his intelligence and an example of this is in the quote ‘To set my brother Clarence and the king in deadly hate, the one against the other’. This shows how he is manipulative and again you must get the audience to believe this about you as well as making them in awe of your intelligence and scheming. It is obvious that Richard is aware of his intelligence, so portray this to the audience with a swagger and self confidence of a man who knows of his large capabilities. A lot of the reasons behind Richards’s hatred for all things jovial is due to his physical deformities and his hatred of his own appearance. He knows of his own deformities, obvious in the line ‘†¦Nor made to court and amorous looking glass’. He does however use this to focus himself on his intentions. An example of this is apparent in the line ‘†¦And therefore, since I cannot prove a lover†¦i am determined to prove a villain.’ These abnormalities should, at first, appear to displease you and annoy you; however within in an instant this should be changed to relief when he realises that his peculiarity can work in his advantage making him focused and more determined to achieve his goals. To make these deformities appear powerfully they must be exaggerated to let the audience know, although his abnormalities are making him more focussed, that they are still a physical weakness and therefore a hindrance. This can be achieved by appearing dependant on a cane that you shall be carrying. This is to give the impression that physically you are dependant upon other people or objects. This will also provide opportunities for people to attack you and taunt your disabilities, such as the cane could be kicked from beneath you and you could use it to regain your feet, again showing physical dependency. The focus that has stemmed from these disabilities must be showed prominently also. Richards focus is clear in the quote’ For then I’ll marry Warwick’s youngest daughter.’ This shows us what lengths he is willing to go to get and then keep the crown in his family after his death. His efficiency and preparation must be extravagant to give the audience reason to believe Richards apparent relief that his deformities can focus him on success. This means also that, regardless of the situation, you appear in control and assured, particularly in the earlier scenes of the play. From this scene where Richard is efficient, assured and organised, we move onto the other key scene. This is the eve of battle scene where both Richard and, his enemy, Richmond are preparing themselves and their army for battle. The scene starts with a quote from Richard saying ‘Why, out battalia trebles that account; besides the Kings name is a Tower of strength’. I for one believe that this act of confidence is one where the speaker, in this case Richard’ has very little faith in his comment so I would appreciate you saying this line with a distinct lack of conviction in your own remark. It seems to me also that with this comment he is not only trying to convince those listening of his army’s strength, but he is also convincing himself. His apparent lack of confidence is than compounded by the appearance of the ghosts. There are many quotes from the ghosts to Richard. A typical example of this would be ‘And fall thy edgeless sword; despair and die!’ which was said by the ghost of Clarence. These quotes must appear to affect you now as perhaps they wouldn’t have done in the earlier scenes. These effects include paranoia and further dents to your confidence which can be acted by adjusting your posture and body language. Then when he awakes from this dream he is convinced he has awaken from battle. Evidence of this is in the line ‘Give me another Horse! Bind up my wounds’ and following this he begins to question his conscience for the first time which is present in the quote ‘O coward conscience, how dost thou afflict me’. This shows us that he is no longer invulnerable and that the atrocities he has committed are beginning to take effect on him.

Biomedical Technology In Ethics and Religion

here are many misconceptions in biomedical genealogy, mostly caused by the many viewpoints and opinions concerning it. When formulating opinions and viewpoints, it Is crucial to be properly educated about that particular topic. The lack of knowledge and moral dispute may hinder clientele research. Although critics argue that it is unethical to manipulate DNA, with genetic manipulation, certain diseases can be eliminated, and cloning holds the ability to produce human organs viable for transplant.Critics argue that it Is unethical to manipulate DNA Some say it Is dangerous because there Is not much knowledge about it. However, genetic manipulation is not a new concept. Some may say that Hitler had this idea before most scientists. An Aryan race is what Hitler striver for. If only he knew that his idea of deciding what genes people receive would carry on even to this day. Scientists are discovering new ways to control what traits are passed through heredity. In the future parents may g et to decide what traits their children receive.This breakthrough in technology is very controversial. â€Å"Some critics continue to argue that it's unethical to manipulate the genetic makeup of human eggs even if here Specter of Human Cloning†). Many religious and moral leaders believe that manipulating DNA crosses a boundary that only God has the right to cross. Many also believe that scientists should not use human embryo in testing because it is wasting human life. Scientists are developing new tests that can determine whether or not a child has a birth defect or disability very early on In pregnancy.In this, parents can decide if they would like to keep their child or not. Religious and ethical people are outraged at such tests because they believe that human life should not be a choice. The problem is that researchers aren't allowed to use human embryo in such tests, Knish said, so Instead, they use animal embryo†(Peeler 6). The conflict with using animal embryo, Is that scientists do not get the same results as they would if they were to use human embryo. People expect exact results and breakthrough discoveries but they are not willing to pay the price.Genetic manipulation holds the chance that certain diseases can be eliminated. This Is one of the many benefits that come with genetic manipulation. Some say that scientists are finding new ways to control what traits get passed through heredity. If that is so, scientists can make the traits that carry heritable diseases vanish. If scientists can manipulate DNA to relinquish the formation of certain diseases, they will know what causes that disease. This advancement will not only prevent people from obtaining disease but will also eliminate It In people who already have It. We will see disease eliminated in the future, or we will witness the creation of new and 1 OFF unleashed†(Decolletage 75). Some believe that once technology goes so far it will be an unstoppable, dangerous force. Ma ny think that scientists manipulating DNA is imply too far. â€Å"Can we, however, ignore opportunities to improve human health†(Decolletage 51). What if no one in the world had cancer, down syndrome, or other disabilities and diseases? People would not oppose research so much if they knew what the outcome would be. People are afraid to take risks; they do not want to put their fate in someone else's hands.What if those hands cured illness and disease? In addition, new biomedical technology such as cloning holds the possibility of cloning human organs that are viable for transplant. Thousands of people each year die because of organ shortages. Cloning human organs can eliminate this epidemic. If organs can be specially made for each individual who needs one, organ transplant waiting lists can be eliminated. â€Å"†¦ An average of 18 people die each day waiting for transplants that can't take place because of the shortage of donated organs†(â€Å"The Need Is Real: Data†).These deaths can be prevented by cloning. However, many people believe that cloning is very unethical and goes against religion. This hinders the formation of cloning and holds back scientists from imperative research. The lack of support given by the people for cloning research impedes government and local ending and aid. The delay in funding and aid creates a rift in research. Many people support biomedical technology and cloning, but only to a certain extent. Most religious people are concerned about cloning because they believe that only God has the right to give and take life in any form.In reality, fear and the lack of knowledge inhibit many religious and ethical people from supporting the idea of cloning. â€Å"If we hope to direct the course of this powerful technology, we should strive to learn as much as we can about these molecular tools and then let scientists and corporations know our wishes. Only then can we truly expect to avoid the risks and enjoy the progress and the promises of our genetic future†(Decolletage 112). Advocates and antagonists both need to strive for further knowledge about this subject in order to tell scientists exactly what they want.How can scientists know how far to take their new technology, if no one has the correct knowledge to tell them where is too far? In conclusion, there are many opinions and viewpoints on the topic of biomedical technology. These can help but they can also hinder scientific research in many ways. One of which is the opinion of religious and ethical people. These people can bring up valid points and bring forth new thoughts and useful ideas about biomedical technology, but they can also let their personal views get in the way.Often times the opinions of religious and ethical people are blurred or disrupted by their personal views. This can lead to extremist views that believe all biomedical technology goes against religion and is unethical. Many people will align themselves with one ideal or theology without educating themselves and considering other viewpoints. In order for both sides of this debate to reach a compromise there must be an open forum of to only communication but also education between both parties.

Coke Is Better Than Pepsi Essay

Pepsi and Coca Cola have long been rivals in the marketing industry and two most recognizable names in soft drinks. Together they produce the #1 (Coca Cola), #2 (Diet Coke) and #3 (Pepsi) soft drinks in the United States and each make tens of billions of dollars in profits every year. Since 1886, Coke has been going strong holding the award of â€Å"Best Soda Drink in the World.† In 2011, Coke still beats Pepsi in sales and long-term taste tests. I totally agree because to me, Coke is better any day! The taste, the emotional brandings, and their marketing techniques are some of the reasons everyone is addicted to coke! The taste is unbelievable and definitely â€Å"to die for.† Pepsi tastes sweeter than Coke. While this often makes consumers initially like the product more than Coke, but people have reported that the more they drink it the less enjoyable the drink is. Coca Cola’s flavour is way more bitter and sweet, which allows you to drink over long periods of time. It just becomes something you enjoy forever unlike Pepsi. Coke has highly visible spots on top-rated shows like â€Å"The Voice† and the Super bowl. Coca Cola gets its brand in front of more people. In the last few years, Pepsi has opted for less traditional campaigns that have not had huge payoffs. Coca Cola is more marketable and more put together as a whole, which allows them to not only sell more products, but make more money on top of that. We love good old Coke! It suits all of our thirst as a whole and puts a smile on our faces. The taste, the emotional brandings, and their marketing techniques keep everyone LOVING Coke, just as much as I do if not more!
