The History of the Kaleidoscope and David Brewster

The kaleidoscope was invented in 1816 by Scottish scientist, Sir David Brewster (1781–1868), a mathematician and physicist noted for his various contributions to the field of optics.  He patented it in 1817 (GB 4136), but thousands of unauthorized copycats were constructed and sold, resulting in Brewster receiving little financial benefits from his most famous invention. Sir David Brewsters Invention Brewster named his invention after the Greek words kalos (beautiful), eidos  (form), and scopos  (watcher). So kaleidoscope roughly translates to beautiful form watcher. Brewsters kaleidoscope was a tube containing loose pieces of colored glass and other pretty objects, reflected by mirrors or glass lenses set at angles, that created patterns when viewed through the end of the tube. Charles Bushs Improvements In the early 1870s, Charles Bush, a Prussian native living in Massachusetts, improved upon the kaleidoscope and started the kaleidoscope fad. Charles Bush was granted patents in 1873 and 1874 related to improvements in kaleidoscopes, kaleidoscope boxes, objects for kaleidoscopes (US 143,271), and kaleidoscope stands. Charles Bush was the first person to mass manufacture his parlor kaleidoscope in America. His kaleidoscopes were distinguished by the use of liquid-filled glass ampules to create even more visually stunning effects. How Kaleidoscopes Work The kaleidoscope creates reflections of a direct view of the objects at the end of a tube, through the use of angled mirrors set at the end; as the user rotates the tube, the mirrors create new patterns. The image will be symmetrical if the mirror angle is an even divider of 360 degrees. A mirror set at 60 degrees will generate a pattern of six regular sectors. A mirror angle at 45 degrees will make eight equal sectors, and an angle of 30 degrees will make twelve. The lines and colors of simple shapes are multiplied by the mirrors into a visually stimulating vortex.

What Brings a Poem to Life - 1134 Words

Poetry, like any other piece of literature, is written to express certain emotion,feeling or idea as desired by the author. Without a defined format, poems come in all sorts of variations, each with it’s own sound,smell, and taste. The most successful poems masterfully give readers the Ah Ha! experience and invoke in them incomprehensible emotions that render them vulnerable to the poets message. William Shakespeare’ s Sonnet 18 and Sylvia Plath’s Metaphors adequately contain imagery,lineation,and tone to shape the meaning and allow the rest to the readers perception.However, no matter how elegant the poem may be structured the poem is nothing without the readers interpretation.

True Love Poem by Robert Penn Warren is an ideal example of the effect of lineation. Freckled.

â€Å"Even the Good can be Twisted† â€Å"Be who you are and say what you feel, because those who mind don’t matter and those who matter don’t mind. † ( Dr. Seuss) â€Å"Even though I walk through the valley of the shadow of death, I will fear no evil. We will write a custom essay sample on The Crucible-Theme- 5-Paragraph or any similar topic only for you Order Now † (Psalm 23:4) â€Å"God has given you one face, and you make yourself another. † (William Shakespeare) These quotes, found throughout many different time periods of history, all say the same: â€Å"Be who you are and don’t let anything change that. † These are great words to live by, but, in time of weakness, does one stay true? Can even the good be twisted? This is a theme that is represented throughout The Crucible many times. Characters such as Elizabeth Proctor, John Proctor, and Reverend Hale had good intentions or morals in the beginning but were soon marred by protecting a lover, temptation, or the questioning of all that one stood on. To begin, Elizabeth Proctor was twisted in a way that was out of love for her husband and his keeping safe. In the beginning, Elizabeth was a character that was known for never lying. She was a woman of Salem that could do no wrong and loved her husband abundantly. Soon, though, her incorruption was challenged when she was brought to court to prove her husband’s innocence. Instead of telling the truth, she lied about the affair that John had previously confessed about. Thinking what was best, detrimental to herself or not, Elizabeth broke the one thing that made her consistent. She chose hurting her own conscience and fate over seeing her husband be punished for a crime he actually committed. As a result of this, Elizabeth’s whole character was altered, changing from a purely good woman to a liar. Simultaneously, John Proctor’s character was distorted in many ways. Even before the play began, John had broken his own moral code by having an affair with Abigail Williams. This went against, not just the rules of the church, but his own personal beliefs and everything he lived by. This caused John to have internal conflict throughout the entire play, making him guilt-ridden. This contention was only to him until he openly stated it in court to prove his wife’s innocence from witchcraft. It was a moot point though, because Elizabeth did the same thing for him, damning him to be ried for taking part in black magic. Only in the end did John Proctor feel any forgiveness towards himself. In his mind, he deserved the punishment he was going to endure and wasn’t going condemn anyone else in the process. All in all, John was a noble man but, warped by temptation, was made a man of slander. Furthermore, Reverend Hale was pushed to change also. Hale came into Salem a st ranger, but knew how to fix the problem the town endured. He never questioned that God had a plan and always thought that something was either good or bad, with no gray area in between. This thinking is challenged when Elizabeth, a pure person, is accused and then later when John confesses. He knows that these people are honest and leaves the court for a period of time. In the end, Hale is a desperate man, and even though knowing there is no witchcraft present, he urges John to admit that he is not the one that should be punished. He has to question all the rules he has lived by his whole life and pursue something he knows is incorrect. In essence, Reverend Hale is pushed to his limits and is turned into a man that will be permanently in suspicion of any standards he ever thought were true. In the end, as a reader, one is challenged to think, if put in that situation, if he or she would falter from what is right. If one would, knowing that is against every precedent and moral one owns, be brought away from all that is good and change? This play shows this theme various times throughout that the good, like Elizabeth, John, and Hale, would be changed when brought up against acting out of love, lust, and doing what is right. The Crucible is continuously asking the reader, â€Å"Can even the good be twisted? † How to cite The Crucible-Theme- 5-Paragraph, Essay examples

In retrospect, was France the best choice for the location of Euro

In retrospect, was France the best choice for the location of Euro-Disney? Sample Essay In retrospect. was France the best pick for the location of Euro-Disney? Not truly. because of the Europeans didn’t stay at the park every bit long as Disney expected. While the Disney succeeded in acquiring close to 9 million visitants a twelvemonth through the park Gatess. in the line with its programs. most stayed merely a twenty-four hours or two. Few stayed the four to five yearss that the Disney had hoped for. It seems that most Europeans regard subject parks merely as topographic points for twenty-four hours jaunts. A subject park is merely non seen as a finish for an drawn-out holiday. Which is besides intending the Gallic people did non pass much in the Disney hotel. This was a large daze for the Disney. because the company had invested one million millions in constructing luxury hotels next to the park-hotels that the day-trippers didn’t demand and that stood half empty in the hotel in the most of the clip. To do the affairs worse. the Gallic didn’t demo up in the expected Numberss. In the 1994. merely 40 per-cents of the park’s visitants were Gallic. One puzzled executive noted that many visitants were Americans populating in Europe or. alien still. What is more surprising was that most of the visitants were the Nipponese travelling to Europe. In the consequence by the terminal of the 1994. the Euro-Disneyland had cumulative losingss of $ 2billion. The entire sum of money spent on epicurean hotels and the loss they had of $ 2 billion by the terminal of 1994. it can clearly state that the France is non a best pick for location of Euro Disney.
