Scarlet Letter Essays (819 words) - Fiction, The Scarlet Letter

Scarlet Letter Hester Prynne was a beautiful, young, tall woman with shiny dark hair, piercing black eyes, and a beautiful complexion. She was living in Amsterdam with her husband, Roger Chillingworth, until he sent her to America alone while he cleared up business matters. In America, Hester had a love affair with Reverend Arthur Dimmesdale and realized she was pregnant with his baby. Nobody realized who the father was, so the Reverend couldn't be punished. However, Hester was forced to wear a large scarlet A(representing Adultery) on her dress. It was a well-known symbol, so everybody knew she had committed adultery and were astonished. This was because adultery was a sin explained in the Seventh Commandment. Hester felt ashamed. After she completed community service, she truly learned her lesson and her citizens accepted her once again. She was also permitted back into Boston after her daughter married and the father of the baby died. She then became a reverend figure whom people confided in and received sympathy from. Reverend Arthur Dimmesdale was young, very pale, and his body was fragile. He had large, caring eyes and a sweet, youthful personality women adored. He was shy and mainly kept to himself. Reverend Dimmesdale was deeply loved by his congregation because of his emotional way of speaking. Being a well-educated, trustworthy, highly admired pastor, no one suspected him to be the father of Hester's baby. Finally, his conscience fell into play and he admitted to his sin. Immediately after confessing, he passed away. Roger Chillingworth was Hester's husband. He was small and thin with dim eyes, a wrinkled face, and deformed shoulders(one was higher than the other). To me, he made an awkward couple with Hester, considering she was considered gorgeous. After he cleared his business matters in Amsterdam, he attempted to join his wife, Hester Prynne, in America. However, he was captured by Indians. By the time he reached his wife, 2 years since he last saw her, she was already up on the scaffold. He visited her in prison and pleaded for her not to reveal the fact he was her husband. He'd be ashamed to marry a disgrace people looked down on. However, he too should have been ashamed. He also committed sins. The first was marrying Hester. Although she had no desire to become hitched to him, he ignored that fact. The love was unrequited. The other sin was when he judged Reverend Dimmesdale and spent hours scheming up plots to make him lose his sanity, while he pretended to be his loyal friend. Pearl was the illegitimate daughter of Hester and Reverend Dimmesdale. Her name was chosen because she was brought into the world at a great price and she's "all Hester had". She was a beautiful girl with "a bright complexion, eyes possessing depth and glow, and glossy, shiny hair." She was graceful and had perfect shape. Her personality was just as perfect. She was extremely smart, imaginative, and determined, so she was most likely to be a huge success. She also showed responsibility. When Hester intentionally tried to lose her scarlet A, it was Pearl who insisted Hester kept it. She was significant because she was a reminder of Hester's love affair and sins. When Chillingworth died, Pearl got a large inheritance. At the end of the book, Pearl was supposedly living in Europe with a member of the nobility as her husband. However, nobody knew exactly where she had gone. The mysterious letters that arrived at Hester's cottage gave the townspeople only vague hints. Master Brackett was the keeper of the prison. He was old with dim eyes and a wrinkly face. He was mentioned only for a short amount of time in the book. He brought Roger Chillingworth to Hester while she was in prison. Also, he smiled and nodded at Pearl and Hester while everybody waited for the Election Day festivities to begin. The Commander was the captain on the ship Hester and Reverend Dimmesdale hoped to board. He was in his middle ages. He made Hester realize Roger Chillingworth would be sailing with Pearl, Reverend Dimmesdale, and Hester herself. Governor Bellingham was the one who witnessed Hester's punishment on the scaffold. A pious Puritan, Governor Bellingham represented political authority in Boston. He was a wealthy, elderly gentleman who spent much of his time consulting with other authority figures such as Dimmesdale. Because he was sympathetic, Hester pleaded to him not to let Pearl be taken away from her. Mistress Hibbins - Mistress Hibbins was Governor Bellingham's sister. She lived in the

Oscillation and Periodic Motion in Physics

Oscillation and Periodic Motion in Physics Oscillation refers to the repeated back and forth movement of something between two positions or states. An oscillation can be a periodic motion that repeats itself in a regular cycle, such as a sine wave- a wave with perpetual motion as in the side-to-side swing of a pendulum, or the up-and-down motion of a spring with a weight. An oscillating movement occurs around an equilibrium point or mean value. It is also known as periodic motion. A single oscillation is a complete movement, whether up and down or side to side, over a period of time. Oscillators An oscillator is a device that exhibits motion around an equilibrium point. In a pendulum clock, there is a change from potential energy to kinetic energy with each swing. At the top of the swing, potential energy is at maximum, and that energy is converted to kinetic energy as it falls and is driven back up the other side. Now again at the top, kinetic energy has dropped to zero, and potential energy is high again, powering the return swing. The frequency of the swing is translated via gears to mark time. A pendulum will lose energy over time to friction if the clock isnt corrected by a spring. Modern timepieces use the vibrations of quartz and electronic oscillators, rather than the movement of pendulums. Oscillating Motion An oscillating motion in a mechanical system is swinging side to side. It can be translated into a rotary motion (turning around in a circle) by a peg-and-slot. Rotary motion can be changed to oscillating motion by the same method. Oscillating Systems An oscillating system is an object that moves back and forth, repeatedly returning to its initial state after a period of time. At the equilibrium point, no net forces are acting on the object. This is the point in the pendulum swing when its in a vertical position. A constant force or a restoring force acts on the object to produce the oscillating motion. Variables of Oscillation Amplitude is the maximum displacement from the equilibrium point. If a pendulum swings one centimeter from the equilibrium point before beginning its return journey, the amplitude of oscillation is one centimeter.Period is the time it takes for a complete round trip by the object, returning to its initial position. If a pendulum starts on the right and takes one second to travel all the way to the left and another second to return to the right, its period is two seconds. ​Period is usually measured in seconds.Frequency is the number of cycles per unit of time. Frequency equals one divided by the period. Frequency is measured in Hertz, or cycles per second. Simple Harmonic Motion The motion of a simple harmonic oscillating system- when the restoring force is directly proportional to that of the displacement and acts in the direction opposite to that of displacement- can be described using sine and cosine functions. An example is a weight attached to a spring. When the weight is at rest, its in equilibrium. If the weight is drawn down, theres a net restoring force on the mass (potential energy). When its released, it gains momentum (kinetic energy) and keeps moving beyond the equilibrium point, gaining potential energy (restoring force) that will drive it in oscillating down again.
