What You Should Know About Electronics

Electronics is the branch of physics that deals with the emission and effects of electrons and the operation of electronic devices. How Is Electronics Different From Electricity? Many devices, from toasters to vacuum cleaners, use electricity as an energy source. These electrical devices transform the electrical current they receive through your wall socket and transform it into another form of energy. Your toaster, for example, transforms electricity into heat. Your lamp transforms electricity into light. Your vacuum cleaner transforms electrical energy into motion that drives the vacuums motor. Electronic devices, however, do more. Instead of transforming electrical energy into heat, light, or motion, they actually manipulate the electrical current itself. In this way, electronic devices can add meaningful information to the current itself. Thus, an electric current can be manipulated to carry sound, video, or data. Most devices are both electrical and electronic. For example, your brand new toaster may transform electricity into heat and also manipulate the current using a thermostat that maintains a specific temperature. Similarly, your cell phone needs a battery to provide electrical energy, but it also manipulates electricity to transmit sound and pictures. History of Electronics While we think of electronics as a modern field, it has actually been around for well over 100 years. In fact, the first manipulation of electrical currents for practical purposes began in 1873 (with Thomas Edison). The first major breakthrough in electronics occurred in 1904, with the invention of the vacuum tube (also called the thermionic valve). Vacuum tubes made possible the invention of TV, radio, radar, telephones, amplifiers, and even microwave ovens. In fact, they were used throughout most of the 20th century and are even in use in some places today. Then, in 1955, IBM introduced a calculator that used transistor circuits without vacuum tubes. It contained no fewer than 3,000 individual transistors. Digital technology (in which information is shared using a combination of 0s and 1s) became easier to design with the use of transistors. Miniaturization has led to a revolution in digital technology. Today, we think of electronics as relating to high tech fields such as computer design, information technology, and design of electronic devices. The reality, however, is that electricity and electronics are still very closely allied. As a result, even auto mechanics must have a good understanding of both fields. Preparing for a Career in Electronics The field of electronics is vast, and electronic engineers generally make a very good living. If you are planning to go to college, you may choose to major in electronic engineering, or you may choose a university where you can specialize in a particular field such as aerospace, telecommunications, or manufacturing. In any case, you will be learning about the physics and practical uses of electricity and electromagnetism. If you are not going the college route, you have several good options in the field of electronics. Electricians, for example, are often trained through apprenticeship programs; todays electricians must also be up to date with electronics, as most projects require a working knowledge of both. Other options include electronic sales, manufacturing, and technician jobs.

The Importance Of Communication In Foreign Language Students

When it comes to varied communication among cultures, teaching language can be complex. In many educational programs, culture has been neglected or mistreated when it comes to teaching foreign languages. Culture is often thought as a supplementary topic but attention is needed to bring forward considering that culture is the highlight of communication to foreign language students. Another study has been conducted to analyze English as a second language program in schools. Anne Ma and her colleagues (2014) address several approaches when it comes to teachers preparing and teaching students who are from another country. The main purpose of the study was to enrich the understanding of the English as a second language student and perform a†¦show more content†¦As Ma s research continues, the analysis of the interviews was used to calculate the responses from the participants to their language confidence and attitudes towards immersion on culture. To support the researchers calc ulations, the use of the Strategies Inventory for Learning Culture, developed by Michael Paige, helped organize the categories for learning the culture and the strategies that were used. The Strategies Inventory for Learning Culture consisted of activities which helped to improve English and strategies to help communicate. As a result, the participants response to the interviews calculated high percentages to speaking and listening strategies when it comes to learning English as a second language. The least strategy effective in learning English was writing and translation. The findings also show, when the participant engage in conversations with dominant English language speakers, they tend to develop a broader knowledge of the culture. The listening strategies mentioned helps the participants to comprehend as they become more engaged with the English dialect. Another strategy that has helped the participants to cope with the new language and culture was setting aside their own beliefs and values, as well, changing their mindset and becoming adjusted to the new culture.

Reflective Log Post Modernity Free Essays

Through the lecture of week 2, I understood the definition of post modernity. It is defined that ‘Post modernity is a reaction to the advanced alienation of late capitalism tempt to restore some meaning to the existential despair over the growing irrationality of modernity’ (Lee, 1992). In addition, I also learned that post modernity has many characteristics which consists of hyper reality, chronology, fragmentation, dedifferentiation, pastiche, anti-foundationalism, reversals of production and consumption, decentering of subject and paradoxical juxtapositions. We will write a custom essay sample on Reflective Log: Post Modernity or any similar topic only for you Order Now However, I did not understand what they are and it is really complex to learn initially. After the lecture, I knew them better than before. For example, Disney land theme parks all over the world could be strongly reflected the hyper reality. Personally, Hyperrealism is a symptom of postmodern culture. Hyper reality does not â€Å"exist† or â€Å"not exist. It is simply a way of describing the information to which the consciousness is subject. I good understand about this feature. Furthermore, take ‘Hui Li’ Sneakers in China as a good example. This brand sneaker is popular in 1990s, and goes out of the market for nearly 20 years, but it is popular on the market up again as the symbol of the main trend. Moreover, pastiche as a feature in post modernity was reflected interestingly. For example, in the post modern society, those creative people are not rigidly adhere to old things and want to use modern elements on the basis of the original classics. A famous oil painting of ‘The Last Supper’ by Leonardo da Vinci was recreated in a new interesting style. I have understood three features of hyper reality, chronology and pastiche very well. Nevertheless, the rest features are not so well understanding about them, and I will continually learn them step by step. How to cite Reflective Log: Post Modernity, Essay examples
