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.

Hanford Site
The Hanford Site is a decommissioned nuclear production complex on the Columbia River in south-central Washington operated by the United States government. Established in 1943 as part of the Manhattan Project, it was home to the B-Reactor, the first full-scale plutonium production reactor in the world. During the Cold War, the project was expanded to include nine nuclear reactors and five massive plutonium processing complexes, which produced plutonium for most of the 60,000 weapons in the U.S. nuclear arsenal. Nuclear technology developed rapidly during this period, and Hanford scientists produced many notable technological achievements. However, many of the early safety procedures and waste disposal practices were inadequate. Government documents have since confirmed that Hanford's operations released significant amounts of radioactive materials to the air and to the Columbia River, threatening the health of residents and ecosystems. Today, Hanford is the most contaminated nuclear site in the United States and is the focus of the nation's largest environmental cleanup effort. While most of the current activity at the site is related to the cleanup project, Hanford also hosts a commercial nuclear power plant, the Columbia Generating Station, and various centers for scientific research and development.

Benjamin Mountfort
Benjamin Mountfort was an English emigrant to New Zealand, where he became one of that country's most prominent 19th-century architects. He was instrumental in shaping the city of Christchurch. He was appointed the first official Provincial Architect of the developing province of Canterbury. Heavily influenced by the Anglo-Catholic philosophy behind early Victorian architecture he is credited with importing the Gothic revival style to New Zealand. His Gothic designs constructed in both wood and stone in the province are considered to be unique to New Zealand. Today he is considered the founding architect of the province of Canterbury, and he ranks today with his contemporary R A Lawson as one of New Zealand's greatest 19th century architects.

In the 1860s, New Zealand was a developing country, where materials and resources freely available in Europe were absent in New Zealand. When available they were often of inferior quality. His monumental Gothic stone civic buildings in Christchurch, which would not be out of place in Oxford or Cambridge, are an amazing achievement over adversity of materials.
