Application of scientific knowledge A steam turbine with the case opened. Such turbines produce the majority of the electricity used today. Electrical power usage and living requirements are highly correlated. Electrification is thought to be the most important engineering accomplishment of the 20th century.  Innovation (" science of craft", from Greek, techne, "art, ability, cunning of hand"; and -,) is the sum of strategies, skills, techniques, and processes used in the production of goods or services or in the achievement of objectives, such as scientific investigation. Innovation can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to enable operation without comprehensive knowledge of their workings.
g. makers) using technology by taking an input, altering it according to the system's usage, and then producing an result are described as innovation systems or technological systems. The easiest form of technology is the advancement and usage of fundamental tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the offered sources of food, and the innovation of the wheel helped humans to travel in and control their environment. Developments in historical times, consisting of the printing press, the telephone, and the Internet, have actually reduced physical barriers to communication and permitted people to interact freely on an international scale.
It has helped develop more innovative economies (consisting of today's worldwide economy) and has actually allowed the rise of a leisure class. Many technological procedures produce unwanted spin-offs referred to as contamination and diminish natural resources to the detriment of Earth's environment. Innovations have actually constantly influenced the values of a society and raised brand-new questions in the ethics of technology. Examples include the rise of the notion of effectiveness in regards to human performance, and the challenges of bioethics. Philosophical arguments have actually occurred over making use of technology, with differences over whether technology improves the human condition or intensifies it. Neo-Luddism, anarcho-primitivism, and comparable reactionary motions criticize the pervasiveness of innovation, arguing that it hurts the environment and alienates individuals; supporters of ideologies such as transhumanism and techno-progressivism view continued technological development as useful to society and the human condition.
