Application of scientific knowledge A steam turbine with the case opened. Such turbines produce most of the electricity used today. Electrical power consumption and living requirements are extremely correlated. Electrification is thought to be the most essential engineering achievement of the 20th century.  Innovation (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the sum of techniques, abilities, approaches, and processes used in the production of products or services or in the achievement of goals, such as scientific examination. Technology can be the knowledge of methods, processes, and so on, or it can be embedded in machines to enable operation without detailed knowledge of their workings.
g. machines) applying innovation by taking an input, changing it according to the system's use, and then producing an outcome are described as technology systems or technological systems. The most basic type of technology is the advancement and usage of standard tools. The prehistoric discovery of how to manage fire and the later Neolithic Transformation increased the readily available sources of food, and the creation of the wheel assisted people to travel in and manage their environment. Developments in historical times, including the printing press, the telephone, and the Internet, have actually lessened physical barriers to interaction and allowed people to connect freely on a worldwide scale.
It has actually assisted establish advanced economies (consisting of today's global economy) and has permitted the rise of a leisure class. Numerous technological processes produce unwanted spin-offs called contamination and deplete natural resources to the detriment of Earth's environment. Developments have always influenced the worths of a society and raised brand-new questions in the ethics of technology. Examples include the increase of the idea of performance in terms of human performance, and the challenges of bioethics. Philosophical arguments have emerged over the use of technology, with disagreements over whether technology enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and comparable reactionary movements slam the pervasiveness of innovation, arguing that it hurts the environment and pushes away people; advocates of ideologies such as transhumanism and techno-progressivism view continued technological progress as helpful to society and the human condition.
