Application of scientific knowledge A steam turbine with the case opened. Such turbines produce most of the electrical power utilized today. Electrical energy intake and living requirements are extremely correlated. Electrification is thought to be the most important engineering accomplishment of the 20th century.  Technology (" science of craft", from Greek, techne, "art, skill, cunning of hand"; and -,) is the sum of techniques, abilities, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as clinical investigation. Technology can be the understanding of strategies, processes, and so on, or it can be embedded in devices to enable operation without detailed understanding of their workings.
g. devices) using innovation by taking an input, altering it according to the system's use, and then producing an result are referred to as technology systems or technological systems. The simplest form of innovation is the advancement and usage of standard tools. The ancient discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel assisted people to take a trip in and control their environment. Developments in historical times, including the printing press, the telephone, and the Internet, have decreased physical barriers to communication and permitted humans to engage freely on a global scale.
It has assisted develop more innovative economies (including today's international economy) and has actually enabled the rise of a leisure class. Many technological processes produce unwanted spin-offs referred to as contamination and deplete natural deposits to the detriment of Earth's environment. Developments have actually constantly affected the values of a society and raised new concerns in the ethics of innovation. Examples consist of the rise of the concept of performance in terms of human productivity, and the challenges of bioethics. Philosophical arguments have actually arisen over the usage of technology, with disputes over whether innovation enhances the human condition or aggravates it. Neo-Luddism, anarcho-primitivism, and comparable reactionary movements criticize the pervasiveness of technology, arguing that it damages the environment and pushes away people; supporters of ideologies such as transhumanism and techno-progressivism view continued technological progress as advantageous to society and the human condition.
