The Technology Portal


Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e. g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.

The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, 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.

Technology has many effects. It 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 Earth's environment. Innovations have always influenced the values of a society and raised new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.

Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing 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.

Hydro-Québec's electricity transmission system
Hydro-Québec's electricity transmission system is an expansive, international power transmission system located in Quebec, Canada with extensions into the Northeastern United States. Major expansion of the network began with the commissioning of the alternating current 735 kV power line in November 1965, as there was a need for electricity transmission over vast distances from hydroelectric power stations in northwestern Quebec and Labrador to southern Quebec. The transmission system, containing over 32,000 kilometres (20,000 mi) of power lines, is managed by Hydro-Québec TransÉnergie, a division of the crown corporation Hydro-Québec. One unique feature of the power system is its alternating current (AC) centers of Montreal and Quebec City to the distant hydroelectric dams and power stations of the James Bay Project and Churchill Falls. The 735 kV power lines serve as the main backbone of the entire transmission system, and thus much of Quebec's population is powered by a handful of 735 kV power lines. This contributed to the severity of the blackout that ensued after the Ice Storm of 1998. The extent and duration of this blackout has generated criticism of the transmission system, and there is controversy concerning the use of hydroelectric dams. Hydro-Québec's electric system is part of the Northeast Power Coordinating Council, even though it technically is its own interconnection, and its own system is minimally connected with other NPCC member utilities.

Featured biography

John Douglas
John Douglas (1830–1911) was an English architect who designed about 500 buildings in Cheshire, North Wales and northwest England, in particular in the estate of Eaton Hall. Douglas' output included the creation, restoration and renovation of churches, church furnishings, houses and other buildings. His architectural styles were eclectic and many of his works incorporate elements of the English Gothic style. He was also influenced by architectural styles from the mainland of Europe and included elements of French, German and Netherlandish architecture into his works. He is remembered for his use of half-timbering, tile-hanging, pargeting, decorative brick in diapering and the design of tall chimney stacks. Of particular importance is Douglas' use of joinery and highly detailed wood carving. Throughout his career he attracted commissions from wealthy landowners and industrialists. Most of his works have survived. The city of Chester contains a number of his structures, the most admired of which are his half-timbered black-and-white buildings and Eastgate Clock. The highest concentration of his work is found in the Eaton Hall estate and the surrounding villages of Eccleston, Aldford and Pulford.
