The Technology Portal


Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .

  • Principle is a term defined current-day by Merriam-Webster as: "a comprehensive and fundamental law, doctrine, or assumption", "a primary source", "the laws or facts of nature underlying the working of an artificial device", "an ingredient (such as a chemical) that exhibits or imparts a characteristic quality".
  • Process is a term defined current-day by the United States Patent Laws (United States Code Title 34 - Patents) published by the United States Patent and Trade Office (USPTO) as follows: "The term 'process' means process, art, or method, and includes a new use of a known process, machine, manufacture, composition of matter, or material."
  • Nomenclature is term defined by Merriam-Webster as: "name, designation", "the act or process or an instance of naming", "a system or set of terms or symbols especially in a particular science, discipline, or art" .
  • Application of Science is a term defined current-day by the United States' National Academies of Sciences, Engineering, and Medicine as: "...any use of scientific knowledge for a specific purpose, whether to do more science; to design a product, process, or medical treatment; to develop a new technology; or to predict the impacts of human actions."

The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. 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.

Technology has many effects. 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. 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.

Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.

Sholes and Glidden typewriter
The Sholes and Glidden typewriter was the first commercially successful typewriter. Principally designed by Christopher L. Sholes, it was developed with the assistance of Samuel W. Soule and Carlos S. Glidden. The machine was acquired by E. Remington and Sons in early 1873. An arms manufacturer seeking to diversify, Remington further refined the typewriter before finally placing it on the market on July 1, 1874. During its development, the typewriter evolved from a crude curiosity into a practical device, the basic form of which became the industry standard, incorporating elements which became fundamental to typewriter design, such as a cylindrical platen and a four-rowed QWERTY keyboard. Several design deficiencies remained, however. The Sholes and Glidden could print only upper-case letters and the typist could not see what was being written as it was entered. Initially, the typewriter received an unenthusiastic reception from the public. Lack of an established market, high cost, and the need for trained operators slowed its adoption. The new communication technologies and expanding businesses of the late 19th century had created a need for expedient, legible correspondence, and so the Sholes and Glidden and its contemporaries soon became ubiquitous office fixtures.

An original drawing by Zobel of a band-pass filter used for impedance matching
Otto Julius Zobel (1887–1970) was a design engineer who worked for the American Telephone & Telegraph Company (AT&T) in the early part of the 20th century. Zobel's work on filter design was revolutionary and led, in conjunction with the work of John R. Carson, to significant commercial advances for AT&T in the field of frequency division multiplex (FDM) telephone transmissions. Although much of Zobel's work has been superseded by more modern filter designs, it remains the basis of filter theory and his papers are still referenced today. Zobel invented the m-derived filter and the constant-resistance filter, which remains in use. Zobel and Carson helped to establish the nature of noise in electric circuits, concluding that—contrary to mainstream belief—it is not even theoretically possible to filter out noise entirely and that noise will always be a limiting factor in what it is possible to transmit. Thus, they anticipated the later work of Claude Shannon, who showed how the theoretical information rate of a channel is related to the noise of the channel.

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors suspended by towers or utility poles.
