Challenger Essays - Space Shuttle Challenger Disaster,

Challenger It was a cold, crisp, and damp morning on the Florida Space Coast as the space shuttle Challenger raced through the sky at speeds approaching mach 2 at an altitude of 104,000 feet when something went perilously wrong. All of America watched, including the family members of the seven doomed crew members, as Challenger exploded into an expansive ball of fire, smoke and steam. An "Oh. . . no!" came as the crew's final utterance from the shuttle as the orbiter broke-up. As the reality of what she was seeing became apparent, Pilot Michael John Smith's daughter, 9 year old Erin Smith, could be heard yelling, "Daddy! Daddy! I want you, Daddy! You promised nothing would happen!" Unfortunately, the events of that tragic day could have been easily prevented. Weather had been the main cause for five delays during the last month. The launch had been carried out in spite on the fact that weather was the worst it had ever been in NASA's history of manned space flight. With so many ! delays encountered in that twenty-fifth shuttle mission, NASA had become careless in getting Challenger on its way. As Challenger sat on the pad awaiting it's ill-fated mission, there were signs that there was something wrong with the Right hand SRB (Solid Rocket Booster). Nevertheless these signs were ignored by a neglectful staff whose only concern was scheduling and not safety. Also, at the time of the accident, for purely monetary reasons, the shuttle had not been fitted with a means of escape for the crew in the case of an emergency; a fact not revealed until after the accident. Though the Space shuttle was the cutting edge of technology at the time, new advancements in technology make the Space Shuttle old, unsafe, inefficient, and not cost effective. However, because of cut backs in funding, NASA is unable to make any advancements in it's technology to prevent another catastrophic accident for the space program. Also as a result of the cut backs, NASA has had tro! uble keeping the existing space shuttles' hardware kept up. The effects of the accident were numerous; the space program was shut down for three years. Also the effects on the NASA staff were immense, leaving a feeling of guilt and fear. On January 28, 1986, the space shuttle Challenger and it's crew embarked on a mission to broaden educational horizons and promote the advancement of scientific knowledge; their mission was cut short in one of the most tragic and most easily prevented tragedies in America's history in space. Before the accident, the 51-L (This mission's assigned number) mission was supposed to be remembered for many reasons. One reason was that this was to be the twenty-fifth space shuttle mission. Another reason was that this was to be the first shuttle launch from pad 39-b which hadn't been used since the Apollo missions. However, The major reason was this was to be the first crew to include a civilian member. Sharon Chista McAuliffe was chosen from a pool of 11,400 applicants. McAuliffe, 37, was a social studies teacher in Concord High School in New Hampshire. While in space, she planned to still teach two lessons entitled, "Where we've been, where we're going, why?", to her class. Then, at T plus 1:13, the mission and its crew became remembered for other, more disastrous reasons. An O-ring in the right SRB shattered in the extreme cold and began allowing liquid hydrogen to leak then explode incinerating the seven crew members, destroying the valuable payload, and bring! ing the space program to a halt for nearly three years. America listened a long ten seconds before "?the commentary was resumed in a tense monotone"(Lewis, p21); "Flight Controllers are looking very carefully at the situation. Obviously a major malfunction. We have no downlink. We have a report from the flight dynamics officer that the vehicle has exploded. The flight director confirms that. We are looking at checking with recovery forces to see what can be done at this point. Contingency procedures are in effect. We will report more as we have information available?"(Lewis, p21) "Major Malfunction", a phrase that stuck with everyone watching the launch that day. Although later, flight commentator Nesbit would be

St. Augustine' Art of Rhetoric Essay Example | Topics and Well Written Essays - 500 words

St. Augustine' Art of Rhetoric - Essay Example years. I have gone through his works and heard one of his quotes that I really enjoyed because it explained very eloquently one of my main pursuits in life. The quote goes "The world is a book, and those who do not travel read only a page." (Saint Augustine). Hearing that quote got me interested in learning more about this Saint and his life and rhetoric works. St. Augustine was an extremely intelligent man. He was born at Tagaste in proconsul Numidia in 354, to pagan father and a Christian mother. After his first studies in his native city, he went to Carthage, with the financial aid of Romanians, to complete his studies in rhetoric. At the same time, however, he fell a slave to his youthful passions and even became connected with the Manichaean religious sect. After completing his studies, he first established his school at Tagaste, and later at Carthage, where he taught rhetoric for eight years, at the same time studying philosophy and the natural sciences. Augustine was greatly influenced during his education and in his adolescence byCicero, a Roman rhetorician, a great master of Latin rhetoric and composition and especially one of his works in particular,Hortensius. Augustine stated that rhetoric is neither good nor bad in it self, but can be used to effectively defend both what is true and what is false.

Rembrandt Van Rijn's Paintings Term Paper Example | Topics and Well Written Essays - 1750 words

Rembrandt Van Rijn's Paintings - Term Paper Example The paper "Rembrandt Van Rijn's Paintings" explores â€Å"The Blinding of Samson† and â€Å"The Avenge of Samson† by Rembrandt van Rijn. While there have been identified more than 400 original works by Rembrandt that have lived through centuries, no one doubts that in the past there existed many more which, unfortunately, have either been lost or destroyed. Today one may savor the beauty and emotional depth of a variety of portraits created by Rembrandt back in the 17th century. However, what is even more appealing for a modern viewer is Rembrandt’s paintings devoted to the Biblical themes and based on the events either from the Old or New Testament. It is hard to say why exactly, but the Biblical story of the Hebrew hero Samson, who was known to possess inordinate strength and was kind of God’s champion, was particularly interesting to Rembrandt. The art scholars attribute 5 original works by Rembrandt devoted to Samson’s life events. The Blinding of Samson (1636) is probably the most famous of them. Interestingly, it has been found that one more painting that explored the Samson motif was created by Rembrandt almost immediately after The Blinding of Samson. The Avenge by Samson (1638) was completed two years later and was kept in a private collection of Rembrandt’s powerful patron Prince Frederick Hendrick of Orange during his lifetime. Allegedly, it was destroyed during the fire of 1712 or was stolen at the moment of panic in the burning house where it was kept. This paper seeks to explore the meaning., historical context and the form of The Blinding of Samson and, based on this research, hypothesize what the details of The Avenge of Samson might have been. It also focuses on the place these artworks had/might have had in the career of their author – Rembrandt van Rijn. The Blinding of Samson: Form, Meaning and Historical Context The Blinding of Samson was created back in 1636. At that time, artists typically used natural materials that they made themselves, most often oil. The Blinding of Samson is not an exception to that rule. It is written in oil on canvas and it is quite large (235x302 cm). While the painting is an example of the Baroque art and represents the Biblical episode, it is quite naturalistic. It can be attributed to the author’s careful use of form. In particular, this artwork exemplifies â€Å"the dark manner† which was introduced by Rembrandt’s predecessor Caravaggio. In this painting, Rembrandt used luxuriant brushwork which combined with rich color and masterful use of chiaroscuro (the technique of treatment of both light and shade). Specifically, his brushstrokes are, as usual, broad and thick. Also, it is these layers of glaze that evidently provide scenes with extra depth and also gravity. Critics claim that these technique helped Rembrandt depict the mood as well as inner mental feeling of the figures since it accentuated their physical featur es along with expressions on their faces (Encyclopedia of Art, visual-arts-cork.com). In relation to this, Armold Houbraken, a painter and a contemporary of Rembrandt who was familiar with the way the great Dutchman worked described that very often his artworks â€Å"looked as though the paint has been smeared on with a bricklayer’s towel† (van de Wetering 5). Yet, it is this working method that allows his paintings to create an extremely light

Event-Driven Programming Features

Event-Driven Programming Features Event-driven programming known as a computer programming paradigm that used the occurrence of events to determine the control flow of the program. This type of application is designed to detect events as they occur, and use an appropriate event-handling procedure to deal with it, which normally use a callback function or method. Theoretically, event-driven style of programming is supported in all programming languages, but they may different in the way of implement it, for example, its easier to implement in languages that provide high-level abstractions, such as closures. Besides, for other programming environments such as Adobe Flash, they are specifically tailored for triggering program code by events. Generally, there is a main loop in an event-driven application that used to listen for events and triggers a callback function when there are events is detected. Key features and characteristics of event-driven programming Service Oriented Service oriented is a key features in event-driven programming that used to write programs that are made for services and it takes does not slow down the computer as service oriented only consume little of the computer processing power and usually services run in the background of OS. Time Driven In event driven programming, time driven is a paradigm, its a code that runs on a time trigger, time driven can be a specific code that runs on a specific time, which could be once an hour, once a week or once a month, this means its a pre-set to do task. For example, windows update is the example of time driven, which user can set when to update or when to check and download the update. Event Handlers Event handlers is a type of function or method that run a specific action when a specific event is triggered. For example, it could be a button that when user click it, it will display a message, and it will close the message when user click the button again, this is an event handler. Trigger Functions Trigger functions in event-driven programming are a functions that decide what code to run when there are a specific event occurs, which are used to select which event handler to use for the event when there is specific event occurred. Events Events include mouse, keyboard and user interface, which events need to be triggered in the program in order to happen, that mean user have to interacts with an object in the program, for example, click a button by a mouse, use keyboard to select a button and etc. Simplicity of Programming and Ease of Development Event-driven programming is simple and easier to program compared to other type of programming as its very visual, for example you can place a button by just select it and place it onto a form and write a code for it. Event-driven programming also easy for user to insert a pre-written code scripts into an existing application because it allows user to pause the code while its running. Which make developing using event-driven programming is easy. Compare Event Driven Programming with Object-oriented Programming (OOP) As mentioned above, event-driven programming known as a computer programming paradigm that used the occurrence of events to determine the control flow of the program, while objects-oriented programming (OOP) treats datafields as objects manipulated through pre-defined methods only and it constructed over four major principles, which are Encapsulation, Data Abstraction, Polymorphism and Inheritance. JavaScript, ActionScript, Visual Basic and Elm are the example for event-driven programming, while C++, C#, Java, Python, Ruby and Scala are the examples for object-oriented programming. In event-driven programming, a program is executed when they detected an event occur, for example, use mouse to click a button to show a message. Besides, in object-oriented programming, emphasis is given to data and classes are the main part of OOP, which mean classes are the blueprints of object and keep the data secure in the classes, only methods of particular classes are allowed to view the data. The classes are also different between event-driven programming and object oriented programming. In OOP, classes can be created by own while in event-driven programming user must use the defined classes. Object-oriented programming and event-driven programming may use together, which mentioned above that event-driven programming are support in all programming language, its just the way of implement it may different.

Britain And America Revolution :: essays research papers

Since the historical conflict between Great Britain and her North American colonies began to unfold, historians have searched for the reasoning behind it. Many experts have discussed the various reasons for the conflict. Some experts believe the conflict occurred because America and Britain had become vastly different social and political entities. Others say that economical disagreements caused the conflict. However, these economical and social forces worked hand-in-hand to slowly erode away the binds that held America to its Mother Country. The traditional liberties of Britain and the newly established liberties of America were very different. After the French and Indian War, the colonies were “heavily'; taxed to sow together the damaged British pocketbook. These economical problems and social distinctions needed to be mended simultaneously or the war could not be avoided.   Ã‚  Ã‚  Ã‚  Ã‚  First, the traditional liberties of Britain were considerably different from the political and social origins of America. From the beginning, America developed different character than its Mother Country of Great Britain. In New England, where the seeds of revolution were sown, merchants used their shipping trade to defy English duties on sugar. As a result of this, additional troops were sent to the colonies to enforce British laws. Later, when the Quartering Act was passed, Americans complained against not only the taxation, but also an infringement on their rights of property. Before the conflict between Britain and France over the Ohio Valley and Canada, America was given practically free reign over its political liberties too. It set up colonial legislatures and citizenship by the act of owning land. Its government system wasn’t based on birthright and a monarch, they were for individual freedoms and the right to participate in government. But when the “tyrannical'; King George jumped in demanding control of the colonies, they were angered and looked for a way to keep their liberties.   Ã‚  Ã‚  Ã‚  Ã‚  Second, America was taxed by the British government to decrease its national debt. Due to their differences in economic base, Britain was self-sufficient in manufacturing goods and the colonies in agriculture. They both needed each other to survive initially. Later, however, America grew more self-sufficient and was able to survive without Britain’s helping hand. America had developed ships to trade with, which were primarily based in the New England colonies. America developed a strong agricultural base and crop source in the southern plantations and middle, “bread';, colonies. They also utilized these economic resources by generating trade with other countries such as France and her West Indian colonies.
