Free Essays on Parents Have The Greatest Influence on Their Children
Some children grow up among thorns; rough hard families. They are choked by the worries of the world. They have parents who are fearful or always think the worst of them. However, most parents donââ¬â¢t realize they are doing this. Some parents tell children, or even young adults, whatââ¬â¢s wrong and seldom whatââ¬â¢s right. Some parents leave their children to fight their own battles, without giving them a hand. They believe that it will make their child stronger in the long run. These parents donââ¬â¢t realize that instead of making their child stronger, they are actually setting him or her up to fail in adulthood. A series of well-known tests were done with monkeys to show the influence parents have on their children. The test indicates crucial outcomes when the monkeysââ¬â¢ mothersââ¬â¢ didnââ¬â¢t express love. When artificial parents raised a monkey during the first years of its life, the monkey often showed bizarre behaviors as an adult. The monkey would either cower in fear or express abnormal aggressive behavior. When a female monkey was deprived of love from its mother, it later became a poor mother itself, tending to neglect or abuse its infants. This experiment suggests that a close relationship with a warm responsive adult is essential for any childââ¬â¢s emotional development, even an infant monkeyââ¬â¢s (Hilgrad 78). An observation was also done on how the interaction between parents and their children affect the childââ¬â¢s social well-being. The observation showed that the parents of mature and competent children are warm and loving and communicate well. While these parents respect their childââ¬â¢s opinion, they are generally firm and clear about the behavior they consider appropriate. The observation indicated that parents of the children who are moderately self-controlled and self-reliant but somewhat withdrawn and distrustful tend to be controlling and not very warm and affectionate. These parents also werenââ¬â¢t that concerned about...

The History of LCD Technology
The History of LCD Technology An LCD or liquid crystal display is a type of flat panel display commonly used in digital devices, for example, digital clocks, appliance displays, and portable computers. How an LCD Works Liquid crystals are liquid chemicals whose molecules can be aligned precisely when subjected to electrical fields, much in the way metal shavings line up in the field of a magnet. When properly aligned, the liquid crystals allow light to pass through. A simple monochrome LCD display has two sheets of polarizing material with a liquid crystal solution sandwiched between them. Electricity is applied to the solution and causes the crystals to align in patterns. Each crystal, therefore, is either opaque or transparent, forming the numbers or text that we can read.à History of Liquid Crystal Displays In 1888, liquid crystals were first discovered in cholesterol extracted from carrots by Austrian botanist and chemist, Friedrich Reinitzer. In 1962, RCA researcher Richard Williams generated stripe patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electrohydrodynamic instability forming what is now called ââ¬Å"Williams domainsâ⬠inside the liquid crystal. According to the IEEE, Between 1964 and 1968, at the RCA David Sarnoff Research Center in Princeton, New Jersey, a team of engineers and scientists led by George Heilmeier with Louis Zanoni and Lucian Barton, devised a method for electronic control of light reflected from liquid crystals and demonstrated the first liquid crystal display. Their work launched a global industry that now produces millions of LCDs. Heilmeiers liquid crystal displays used what he called DSM or dynamic scattering method, wherein an electrical charge is applied which rearranges the molecules so that they scatter light. The DSM design worked poorly and proved to be too power hungry and was replaced by an improved version, which used the twisted nematic field effect of liquid crystals invented by James Fergason in 1969. James Fergason Inventor James Fergason holds some of the fundamental patents in liquid crystal displays filed in the early 1970s, including key US patent number 3,731,986 for Display Devices Utilizing Liquid Crystal Light Modulation In 1972, the International Liquid Crystal Company (ILIXCO) owned by James Fergason produced the first modern LCD watch based on James Fergasons patent.
