2. 1. ELECTRICITY Today we cant imagine our life without electricity. Everything we use is operated with electricity. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communicatio ns, and computation. Electrical power is the backbone of modern industrial society. The word electricity is from the New Latin lectricus, "amber-like", coined in the year 1600 from the Greek (electron) meaning amber, because electrical effects were produced classically by rubbing amber. 3. Benjamin Franklin conducted extensive research on electricity in the 18th century, as documented by Joseph Priestley (1767) History and Present Status of Electricity, with whom Franklin carried on extended correspondence. 4. 2. LIGHT BULB One of the important invention that brightens millions of houses and buildings. The bulb itself works by transmitting electricity through a wire with high resistance known as a filament. The waste energy created by the resistance is expelled as heat and light. 5. Thomas Alva Edison (February 11, 1847 October 18, 1931) was an American inventor and b usinessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long- lasting, practical electric light bulb. The coastal steamship Columbia became the first application for the light bulb in 1880. It sank after colliding with a schooner off California in 1907. 6. 3. COMPUTERS Computers have drastically changed our lives and open the gates to new emerging world of endless possibilities. They are able to make complicated mathematical calculations at an incredible rate of speed and when they operate under the instructions of skilled programmers, they can accomplish amazing feats. 7. The Jacquard loom, on display at the Museum of Science and Industry in Manchester, England, was one of the first programmable devices. 8. 4. INTERNET The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter- linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks 9. The department of US defence first used a service called ARPANET in the 1960s. Then, in 1989, Tim Berner Lee invented the World Wide Web, which shrank the world like nothing else. Today more than 1.7 billion people, or 25 per cent of the world use the Internet. It is such a powerful invention that weve probably only begun to see its long term effects. 10. 5. EMAIL Electronic mail, most commonly referred to as email or e-mail since approximately 1993, is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and- forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to an email server, for as long as it takes to send or receive messages. 11. The worldwide spread of email affected the exchange of communications. Before email, a business in the US sending an important document overseas printed the document, packaged it, paid for the delivery service and waited days for it to arrive at the destination. After email grew to be a part of all international businesses, companies and students possessed the ability to send formal communications to the recipient in minutes. 12. 6. STEAM ENGINE The Industrial Revolution, which is possibly the greatest change over the shortest period of time in the history of civilization, was carried forward by the steam engine. Now, While the steam engine has been overshadowed by electric and internal combustion engines in the areas of transport and factory power, it is still incredibly important. Most power plants in the world actually generate electricity using steam turbines, whether the steam is heated by burning coal, natural gas, or a nuclear reactor. 13. James Watt, 19 January 1736 25 August 1819) was a Scottish inventor and mechanical engineer whose improvements to the Newcomen steam engine were fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. 14. 7. AUTOMOBILE Do you know there are approximately 600 million passenger cars worldwide? That is roughly one car per eleven people! We all know how important they are in our life and it would be hard to imagine a world without them. An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods 15. 8. AIRCRAFT An aircraft is a machine that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. 16. 9. MOBILE PHONE A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station. 17. Martin "Marty" Cooper (born December 26, 1928 in Chicago, Illinois, USA) is a pioneer and visionary in the wireless communications industry. With eleven patents in the field, he is recognized as an innovator in radio spectrum management. Inventing the handheld cellular Mobile phone. Making world's first handheld cellular mobile phone call. 18. 10. TELEPHONE A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. 19. First patented in 1876 by Alexander Graham Bell and further developed by many others, the telephone was the first device in history that enabled people to talk directly with each other across large distances. Telephones became rapidly indispensable to businesses, government, and households, and are today some of the most widely used small appliances. 20. 11. TELEVISION The etymology of the word has a mixed Latin and Greek origin, meaning "far sight": Greek tele (), far, and Latin visio, sight (from video, vis- to see, or to view in the first person). Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. Since the 1950s, television has been the main medium for molding public opinion. Since the 1970s the availability of video cassettes, laserdiscs, DVDs and now Blu- ray Discs, have resulted in the television set frequently being used for viewing recorded as well as broadcast material. In recent years, Internet television has seen the rise of television available via the Internet through services such as iPlayer and Hulu. 21. Philo Taylor Farnsworth (August 19, 1906 March 11, 1971) was an American inventor and television pioneer. Charles Francis Jenkins (August 22, 1867 June 6, 1934) was an American pioneer of early cinema and one of the inventors of television, though he used mechanical rather than electronic technologies. 22. 12. ROBOTS Robots are helping us in many aspects of life. They are used in car productions, packaging of manufactured goods, mass production of printed circuit boards (PCBs), space probes, military drones (UAVs) and humanoid robots like ASIMO designed and developed by HONDA. ASIMO, which is an acronym for Advanced Step in Innovative Mobility, was created to be a personal assistant. 23. The idea of automata originates in the mythologies of many cultures around the world. Engineers and inventors from ancient civilizations, including Ancient China, Ancient Greece, and Ptolemaic Egypt, attempted to build self-operating machines, some resembling animals and humans. Early descriptions of automata include the artificial doves of Archytas the artificial birds of Mozi and Lu Ban a "speaking" automaton by Hero of Alexandria, a washstand automaton by Philo of Byzantium, and a human automaton described in the Lie Zi. 24. 13. GAMING CONSOLES A video game console is an interactive computer that produces a video display signal which can be used with a display device (a television, monitor, etc.) to display a video game. The term "video game console" is used to distinguish a machine designed for people to buy and use primarily for playing video games on a TV in contrast to arcade machines, handheld game consoles, or home computers. The video game console was first invented in the 1950s and has continued to evolve, with the latest consoles being
