A steam turbine
with the case opened. Such turbines produce most of the electricity used today. Electricity consumption and living standards are highly correlated. Electrification is believed to be the most important engineering achievement of the 20th century.
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.
The Lockheed Martin F-16 Fighting Falcon
is a multirole jet fighter aircraft
originally developed by General Dynamics
for the United States Air Force
. Designed as a lightweight fighter, it evolved into a successful multirole aircraft. The Falcon's versatility is a paramount reason it has proven a success on the export market, having been selected to serve in the air forces of 25 nations. The F-16 is the largest Western jet fighter program with over 4,400 aircraft built since production was approved in 1976. Though no longer being bought by the U.S. Air Force, advanced versions are still being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation
, which in turn became part of Lockheed Martin
after a 1995 merger with Martin Marietta
. The Fighting Falcon is a dogfighter
with numerous innovations including a frameless, bubble canopy
for better visibility, side-mounted control stick to ease control while under high g-forces
, and reclined seat to reduce the effect of g
-forces on the pilot. Weapons include a M61 Vulcan
cannon and various missiles mounted on up to 11 hardpoints
. It was also the first fighter aircraft deliberately built to sustain 9-g
turns. It has a thrust-to-weight ratio
greater than one, providing enough power to climb and accelerate vertically – if necessary. Although the F-16's official name is "Fighting Falcon", it is known to its pilots as the "Viper
", due it resembling a cobra snake and after the Battlestar Galactica starfighter
. It is used by the Thunderbirds air demonstration team

Did you know...
is a custom knifemaker, martial artist
, and edged-weapons authority who founded Emerson Knives, Inc in 1996. Once known for making "art knives", he later became better known as one of the knifemakers who started the Tactical Knife trend in the early 1990s with his award winning cutlery. Emerson's knives have been displayed as museum
pieces, carried by Navy SEALs
, used by NASA
in outer space
, and have been featured in books and films, making them valuable and popular with collectors. Emerson's knifemaking career was born from his experience as an engineer and machinist in the aerospace industry coupled with his lifelong study of martial arts
. Drawing on his experience as a craftsman and engineer, Emerson has also begun making custom handmade electric guitars. Emerson's own personally developed fighting technique, Emerson Combat Systems, has been taught to police officers
, elite military units
, and civilians worldwide; making Emerson a highly sought after combatives
, and noted authority on edged-weapons in combat.
