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 the sum 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.

Earthrise
taken from Apollo 8 by William Anders
Apollo 8 was the first crewed spacecraft to leave low Earth orbit and the first to reach the Moon, orbit it, and return. Its three-astronaut crew—Frank Borman, James Lovell, and William Anders—were the first humans to fly to the Moon, to witness and photograph an Earthrise, and to escape the gravity of a celestial body.

Featured biography

I. M. Pei in June 2006
Ieoh Ming Pei (Chinese: 貝聿銘), FAIA, RIBA (English: /j.mɪŋ.ˈp/ yoh-ming-PAY 26 April 1917 – 16 May 2019) was a Chinese-American architect. Born in Guangzhou but raised in Hong Kong and Shanghai, Pei drew inspiration at an early age from the garden villas at Suzhou, the traditional retreat of the scholar-gentry to which his family belonged. In 1935, he moved to the United States and enrolled in the University of Pennsylvania's architecture school, but he quickly transferred to the Massachusetts Institute of Technology. He was unhappy with the focus at both schools on Beaux-Arts architecture, and spent his free time researching emerging architects, especially Le Corbusier. After graduating, he joined the Harvard Graduate School of Design (GSD) and became a friend of the Bauhaus architects Walter Gropius and Marcel Breuer. In 1948, Pei was recruited by New York City real estate magnate William Zeckendorf, for whom he worked for seven years before establishing an independent design firm in 1955, I. M. Pei & Associates. In 1966 that became I. M. Pei & Partners in 1966, and in 1989 became Pei Cobb Freed & Partners. Pei retired from full-time practice in 1990. In his retirement, he worked as an architectural consultant primarily from his sons' architectural firm Pei Partnership Architects. Read more...

Under these policies, coursework completed under online learning will not officially count towards advancing to the next academic term. (The Wall Street Journal)
