Innovations have always influenced the values of a society and raised new questions of the ethics of technology.Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.For example, science might study the flow of electrons in electrical conductors by using already-existing tools and knowledge.This new-found knowledge may then be used by engineers to create new tools and machines such as semiconductors, computers, and other forms of advanced technology.

Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known.More recently, scholars have borrowed from European philosophers of "technique" to extend the meaning of technology to various forms of instrumental reason, as in Foucault's work on technologies of the self (techniques de soi).Dictionaries and scholars have offered a variety of definitions.Developments in historic times, 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. It 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 Earth's environment.As a cultural activity, technology predates both science and engineering, each of which formalize some aspects of technological endeavor.Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science.The spread of paper and printing to the West, as in this printing press, helped scientists and politicians communicate their ideas easily, leading to the Age of Enlightenment; an example of technology as cultural force.The use of the term "technology" has changed significantly over the last 200 years.In the immediate wake of World War II, for example, it was widely considered in the United States that technology was simply "applied science" and that to fund basic science was to reap technological results in due time.An articulation of this philosophy could be found explicitly in Vannevar Bush's treatise on postwar science policy, Science – The Endless Frontier: "New products, new industries, and more jobs require continuous additions to knowledge of the laws of nature ...
