The application of scientific knowledge A steam turbine with the case opened. Such turbines produce most of the electricity used today. Electrical energy usage and living requirements are highly associated. Electrification is thought to be the most crucial engineering achievement of the 20th century.  Innovation (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the sum of methods, skills, methods, and processes utilized in the production of goods or services or in the achievement of goals, such as clinical examination.
Systems (e. g. machines) applying technology by taking an input, altering it according to the system's usage, and then producing an result are referred to as innovation systems or technological systems. The easiest form of innovation is the advancement and usage of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Transformation increased the readily available sources of food, and the invention of the wheel helped human beings to take a trip in and manage their environment.
Innovation has numerous effects. It has actually assisted develop advanced economies (including today's worldwide economy) and has actually enabled the increase of a leisure class. Many technological processes produce undesirable by-products understood as contamination and deplete natural resources to the detriment of Earth's environment. Developments have always affected the worths of a society and raised brand-new questions in the principles of innovation.
Philosophical debates have arisen over making use of technology, with differences over whether innovation enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements slam the pervasiveness of technology, arguing that it harms the environment and pushes away individuals; supporters of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.
Before the 20th century, the term was unusual in English, and it was used either to describe the description or study of the helpful arts or to point to technical education, as in the Massachusetts Institute of Technology (chartered in 1861). The term "technology" rose to prominence in the 20th century in connection with the Second Industrial Revolution.
