The Technology Portal


Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e. g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.

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 in 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.

Electrical engineering
Electrical engineering is a professional engineering discipline that deals with the study and application of electricity, electromagnetism and electronics. The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply and now encompasses a range of sub-disciplines including power, control systems, electronics and telecommunications. Whilst these terms are often used to mean the same, electrical engineering is sometimes distinguished from electronics engineering. Where this distinction is made, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control whereas electronics engineering deals with the study of small-scale electronic systems including semiconductors and the design of integrated circuits. Advances during the 20th century in radio technologies, followed by the invention of early computers and integrated circuits, led to the development of the specialized field. Meanwhile, universities were developing formal programs of study, and today, the field's practitioners generally hold an academic degree in their discipline and may be certified by a professional body.

Featured biography

I. M. Pei
I. M. Pei (born 1917) is a Chinese American architect, often called a master of modern architecture. Born in Guangzhou, in 1935 he moved to the United States. While enrolled at Massachusetts Institute of Technology, he became unhappy with the school's focus on Beaux-Arts architecture, and spent his free time researching the emerging architects, especially Le Corbusier. After graduating, he joined the Harvard Graduate School of Design and formed a friendship with the Bauhaus architects Walter Gropius and Marcel Breuer. Pei spent ten years working with New York real estate magnate William Zeckendorf before establishing his own independent design firm that eventually became Pei Cobb Freed & Partners. Among the early projects on which Pei took the lead were the L'Enfant Plaza Hotel in Washington, DC, and the Green Building at MIT. His first major recognition came with the National Center for Atmospheric Research in Colorado; his new stature led to his selection as chief architect for the John F. Kennedy Library in Massachusetts. He went on to design Dallas City Hall and the East Building of the National Gallery of Art. In the early 1980s, Pei was the focus of controversy when he designed a glass-and-steel pyramid for the Louvre museum in Paris. Pei has won a wide variety of prizes and awards in the field of architecture, including the 1983 Pritzker Prize, sometimes called the Nobel Prize of architecture.
