Dunedin ( (listen) duh-NEE-din; Māori: Ōtepoti) is the second-largest city in the South Island of New Zealand (after Christchurch), and the principal city of the Otago region. Its name comes from Dùn Èideann, the Scottish Gaelic name for Edinburgh, the capital of Scotland.The urban area of Dunedin lies on the central-eastern coast of Otago, surrounding the head of Otago Harbour, and the harbour and hills around Dunedin are the remnants of an extinct volcano. The city suburbs extend out into the surrounding valleys and hills, onto the isthmus of the Otago Peninsula, and along the shores of the Otago Harbour and the Pacific Ocean. Dunedin was the largest New Zealand city by territorial land area until superseded by Auckland with the formation of the Auckland Council in November 2010. Archaeological evidence points to lengthy occupation of the area by Māori prior to the arrival of Europeans. The province and region of Otago takes its name from the Ngāi Tahu village of Otakou at the mouth of the harbour, which became a whaling station in the 1830s. In 1848 a Scottish settlement was established by the Lay Association of the Free Church of Scotland. Between 1855 and 1900 many thousands of Scots emigrated to the incorporated city. Dunedin became wealthy during the Central Otago Gold Rush, beginning in the 1860s. In the mid-1860s, and between 1878 and 1881, it was New Zealand's largest urban area. The city population at 5 March 2013 was 120,246. While Hamilton, Tauranga and Lower Hutt have eclipsed the city in size of population since the 1980s to make it only the seventh-largest urban area in New Zealand, Dunedin is still considered one of the four main cities of New Zealand for historic, cultural and geographic reasons.Dunedin has a diverse economy, which includes manufacturing, publishing and technology-based industries as well as education, research and tourism. The city's most important activity centres around tertiary education—Dunedin is home to the University of Otago, New Zealand's oldest university (established 1869), and the Otago Polytechnic. Students account for a large proportion of the population; 21.6 per cent of the city's population was aged between 15 and 24 at the 2006 census, compared to the New Zealand average of 14.2 per cent. In 2014 Dunedin was designated as a UNESCO City of Literature.

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. 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. The steady progress of military technology has brought weapons of ever-increasing destructive power, from clubs to nuclear weapons.
