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.
An Experiment on a Bird in the Air Pump
is a 1768 oil-on-canvas painting
by Joseph Wright of Derby
, part of a series of candlelit scenes that Wright painted during the 1760s. The Air Pump
departed from previous painting conventions by depicting a scientific subject in the reverential manner formerly reserved for scenes of historical and religious significance. Wright was intimately involved in depicting the Industrial Revolution
and the scientific advances of the Enlightenment
, but while his paintings were recognized as something out of the ordinary by his contemporaries, his provincial status and choice of subjects meant the style was never widely imitated. The picture has been owned by the National Gallery
since 1863 and is still regarded as a masterpiece of British art. The painting depicts a natural philosopher
, a forerunner of the modern scientist, recreating one of Robert Boyle
's air pump
experiments, in which a bird is deprived of oxygen, before a varied group of onlookers. The group exhibit different reactions, but for most scientific curiosity overcomes concern for the bird. The central figure looks out of the picture as if inviting the viewer's participation in the outcome.

Did you know...
(1809–77) was an English architect, architectural historian
, railway engineer, and sanitary
reformer. Sharpe's main focus was on churches, and he was a pioneer in the use of terracotta
as a structural material in church building, designing what were known as "pot" churches. He also designed secular buildings, including domestic properties and schools, and worked on the development of railways in Northwest England, designing bridges and planning new lines. In 1851 he resigned from his architectural practice, and in 1856 he moved from Lancaster, spending the remainder of his career mainly as a railway engineer. Sharpe was involved in Lancaster's civic affairs. He was an elected town councillor and served as mayor in 1848–49. Concerned about the town's poor water supply and sanitation, he championed the construction of new sewers and a waterworks. Sharpe achieved national recognition as an architectural historian. He published books of detailed architectural drawings, wrote a number of articles on architecture, devised a scheme for the classification of English Gothic architectural
styles, and in 1875 was awarded the Royal Gold Medal
of the Royal Institute of British Architects
