edit   The Technology Portal Gunpowder Technology is the practical use of science, including the making, modification or improvement, applied activity or behavior, use and knowledge of tools, machines, techniques, crafts, systems, methods of organization, or environmental modifications or arrangement in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function. It can also refer to the collection of such tools, machinery, modifications, environmental arrangement and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning "art, skill, craft", and -λογία (-logía), meaning "study of-". The term can be applied either generally or to many specific areas, examples of which include construction technology, medical technology and information technology. The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.

The project was developed by the Port Authority of New York and New Jersey, which hired architect Minoru Yamasaki who came up with the specific idea for twin towers. The towers were designed as framed tube structures, which provided tenants with open floor plans, uninterrupted by columns or walls. This was accomplished using numerous, closely-spaced perimeter columns to provide much of the strength to the structure, along with gravity load shared with the core columns. The elevator system, which made use of sky lobbies and a system of express and local elevators, allowed substantial floor space to be freed up for use as office space by making the structural core smaller. The design and construction of the World Trade Center twin towers involved many other innovative techniques, such as the slurry wall for digging the foundation, and wind tunnel experiments. Construction of the World Trade Center's North Tower began in August 1968, and the South Tower in 1969. Extensive use of prefabricated components helped to speed up the construction process. The first tenants moved into the North Tower in December 1970 and into the South Tower in January 1972. Four other, low-level buildings were constructed as part of the World Trade Center in the 1970s, and a seventh building was constructed in the mid-1980s. edit   In this month 7 December 1972 – The Blue Marble (pictured), the most famous photograph of the Earth, is taken by the crew of the Apollo 17 mission 14 December 2004 – The Millau Viaduct, the tallest bridge in the world, near Millau, France, is officially opened 20 December 1996 – NeXT merges with Apple Computer, starting the path to Mac OS X 24 December 1968 – The crew of Apollo 8 become the first humans to orbit around the Moon, and broadcast live TV pictures of the orbit in one of the most watched programs in history More anniversaries... edit   Did you know... ...that cyber law author and professor Jonathan Zittrain co-founded StopBadware.org to distribute the task of collecting data about malware to Internet users at large? ...that Egg Banking plc is now the world's largest "pure" internet bank, meaning it's only accessible from the internet? ... that anarchist Internet archive Spunk Library was once falsely accused of collaborating with the terrorist guerrilla outfit Red Army Faction? edit   Featured biography Edward Teller was a Hungarian-born American nuclear physicist of Jewish descent. He was known colloquially as "the father of the hydrogen bomb". Teller was an immigrant to the United States during the 1930s, and was an early member of the Manhattan Project to develop the first atomic bombs. During this time he made a serious push for the first time to develop fusion-based weapons as well, but they were deferred until after the war. After his controversial testimony in the security clearance hearing of his former Los Alamos colleague J. Robert Oppenheimer, Teller became ostracized by much of the scientific community. He continued to find support from the U.S. government and military research establishment. He was a co-founder of Lawrence Livermore National Laboratory, and was both director and associate director for many years. In his later years he became especially known for his advocacy of controversial technological solutions to both military and civilian problems, including a plan to excavate an artificial harbor in Alaska using thermonuclear explosives. Over the course of his long life, Teller was known both for his scientific ability and his difficult interpersonal relations, and is considered one of the key influences of the character Dr. Strangelove in the 1964 movie of the same name. edit   Wikiprojects Parent project Technology Related projects Architecture Computing Computer Science Electronics Energy development Energy History of Science Metalworking Telecommunications Woodworking What are WikiProjects? edit   Selected quote edit   Selected picture The M198 howitzer is a modern artillery piece that has been in use by the militaries of United States and other nations since 1979. edit   Categories Computing · Classes of computers · Companies · Computer architecture · Computer model · Computer science · Computer security · Computing and society · Data · Embedded systems · Information systems · Information technology · Internet · Languages · Multimedia · Networks · Operating systems · Platforms · Product lifecycle management · Real-time computing · Software · Security ·More...
