The Technology Portal

Technology is the practical use of science, including the making, modification or improvement, applied activity or behavior, use and knowledge of tools, machines, techniques, crafts, systems, methods of organization, or environmental modifications or arrangement in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function. It can also refer to the collection of such tools, machinery, modifications, environmental arrangement and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning 'art, skill, craft', and -λογία (-logía), meaning 'study of-'. The term can be applied either generally or to many specific areas, examples of which include construction technology, medical technology and information technology.

The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, 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. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

Technology has affected society and its surroundings in a number of ways. In many societies, technology 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 the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.

Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining 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. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.

Horseshoe Curve is a 3,485-foot (1,062 m), triple-tracked railroad curve on Norfolk Southern Railway's Pittsburgh Line in Logan Township, Blair County, in the U.S. state of Pennsylvania. It is close to 1,300 feet (400 m) in diameter and has a grade of almost two percent. As a train travels west from Altoona, it ascends almost 60 feet (20 m) in the 0.66-mile (1.06 km) segment that makes up the curve and rotates 220 degrees. The curve was completed in 1854 by the Pennsylvania Railroad as a means of lessening the grade to the summit of the Allegheny Mountains by increasing the distance. It was built as alternative to the time-consuming Allegheny Portage Railroad, the only other method of traversing the mountains. It has formed an important part of the region's transportation infrastructure since its opening, and during World War II was targeted by Nazi Germany in 1942 as a part of Operation Pastorius. Horseshoe Curve was added to the National Register of Historic Places and designated a National Historic Landmark in 1966. It was also designated a National Historic Civil Engineering Landmark in 2004.

Ernest Emerson 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 instructor, author, and noted authority on edged-weapons in combat.
