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 city of Minneapolis
is covered by a citywide broadband wireless internet network
, sometimes called Wireless Minneapolis
. The network was first proposed in 2003, at which point only a few other cities nationwide had such systems in place. Local firm US Internet
beat out EarthLink
to build and operate the network, with a guaranteed ten-year, multi-million-dollar contract from the city itself as the network's anchor tenant. Construction began on the project in 2006, but encountered several delays. Most of the city was covered by the network by 2010, and USI Wireless, the subsidiary of US Internet responsible for the system, set up numerous free internet access points at public locations around Minneapolis. The network, which offers speeds of one to six megabits per second
at a rate of about $20 per month, has about 20,000 residential subscribers and is on track to reach 30,000 subscribers by 2013. Municipally, the network is used by city inspectors and employees, with plans in place for the police and fire departments to use it in the future. In 2007, when the I-35W Mississippi River bridge
collapsed, the wireless system helped coordinate rescuers and emergency services. The city and USI Wireless have won praise for the network, which has been singled out for being one of the few successful municipal wireless ventures
nationwide among a number of stalled or failed projects.

Albert Stanley, 1st Baron Ashfield
(1874–1948) was managing director, then chairman of the Underground Electric Railways Company of London
(UERL) from 1910 to 1933 and chairman of the London Passenger Transport Board
(LPTB) from 1933 to 1947. At a young age, he held senior positions in the developing tramway systems of Detroit and New Jersey. In 1907, his management skills led to his recruitment by the UERL, which was struggling through a financial crisis. He quickly integrated the company's management and used advertising and public relations to improve profits. As managing director of the UERL from 1910, he led the take-over of competing underground railway companies and bus and tram operations to form an integrated transport operation known as the Combine. He was Member of Parliament
from December 1916
to January 1920
and was President of the Board of Trade
between December 1916
and May 1919
. He returned to the UERL and then chaired it and its successor the LPTB during the organisation's greatest period of expansion between the two World Wars, making it a world-respected organisation considered an exemplar of the best form of public administration.
