The Technology Portal


Technology is 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.

Wikimania, annual conference for users of Wikipedia and other Wikimedia projects
Wikipedia is a multilingual, open content, free encyclopedia project operated by the non-profit Wikimedia Foundation. Its name is a portmanteau of the words wiki (a type of collaborative website) and encyclopedia. Launched in 2001, it is the largest, fastest growing and most popular general reference work currently available on the Internet. As of December 2007, Wikipedia had approximately 9 ¼ million articles in 253 languages, comprising a combined total of over 1.41 billion words for all Wikipedias. The English Wikipedia edition passed the 2,000,000 article mark on September 9, 2007. Wikipedia's articles have been written collaboratively by volunteers around the world and the vast majority of them can be edited by anyone with access to the Internet. Critics have questioned Wikipedia's reliability and accuracy, citing its open nature. The criticism is centered on its susceptibility to vandalism, such as the insertion of profanities or random letters into articles, and the addition of spurious or unverified information; uneven quality, systemic bias and inconsistencies; and for favoring consensus over credentials in its editorial process. Scholarly work suggests that vandalism is generally short-lived. When Time Magazine recognized "You" as their Person of the Year 2006, Wikipedia was the first particular "Web 2.0" service mentioned, followed by YouTube and MySpace.

Featured biography

Ben Gascoigne
Ben Gascoigne (1915–2010) was an optical astronomer and expert in photometry. Born in New Zealand, Gascoigne moved to Australia to work at the Commonwealth Solar Observatory at Mount Stromlo in Canberra. He became skillful in the design and manufacture of optical devices such as telescope elements. He and astronomer Gerald Kron used modernised telescopes at Mount Stromlo to determine that the distance between the Milky Way and the Magellanic Cloud dwarf galaxies had been underestimated by a factor of two. Because this measurement was used to calibrate other distances in astronomy, the result effectively doubled the estimated size of the universe. They also found that star formation in the Magellanic Clouds had occurred more recently than in the Milky Way; this overturned the prevailing view that both had evolved in parallel. Gascoigne was involved in the conception and commissioning of the Anglo-Australian Telescope, Australia's largest optical telescope. He was made an Officer of the Order of Australia for his contributions to astronomy and to the Anglo-Australian Telescope. After he retired, Gascoigne acted as curator and photographer for his wife, artist Rosalie Gascoigne, using his technical skills to make her artworks resilient for public display.
