The American Society of Mechanical Engineers (ASME) is a professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, a lobbying organization, a provider of training and education, and a nonprofit organization.

Citroën 2CV

The Citroën 2CV ("deux chevaux" i.e. "deux chevaux-vapeur" (lit. "two steam horses", "two tax horsepower") is an air-cooled front-engine, front-wheel-drive economy car introduced at the 1948 Paris Mondial de l'Automobile and manufactured by Citroën for model years 1948–1990. Conceived by Citroën Vice-President Pierre Boulanger to help motorise the large number of farmers still using horses and carts in 1930s France, the 2CV has a combination of innovative engineering and utilitarian, straightforward metal bodywork — initially corrugated for added strength without added weight. The 2CV featured low cost; simplicity of overall maintenance; an easily serviced air-cooled engine (originally offering 9 hp); low fuel consumption; and an extremely long-travel suspension offering a soft ride and light off-road capability. Often called "an umbrella on wheels", the fixed-profile convertible bodywork featured a full-width, canvas, roll-back sunroof, which accommodated oversized loads and until 1955 reached almost to the car's rear bumper. Notably, Michelin introduced and first commercialized the radial tyre with the introduction of the 2CV. Manufactured in France between 1948 and 1988 (and in Portugal from 1988 to 1990), more than 3.8 million 2CVs were produced, along with over 1.2 million small 2CV-based delivery vans known as fourgonnettes. Citroën ultimately offered several mechanically identical variants including the Ami (over 1.8 million); the Dyane (over 1.4 million); the Acadiane (over 250,000); and the Mehari (over 140,000). In total, Citroën manufactured almost 9 million 2CVs and variants. The purchase price of the 2CV was low relative to its competition. In West Germany during the 1960s, for example, it cost about half as much as a Volkswagen Beetle. From the mid-1950s economy car competition had increased – internationally in the form of the 1957 Fiat 500 and 1955 Fiat 600, and 1959 Austin Mini. By 1952, Germany produced a price competitive car – the Messerschmitt KR175, followed in 1955 by the Isetta – these were microcars, not complete four-door cars like the 2CV. On the French home market, from 1961, the small Simca 1000 using licensed Fiat technology, and the larger Renault 4 hatchback had become available. The R4 was the biggest threat to the 2CV, eventually outselling it. A 1953 technical review in Autocar described "the extraordinary ingenuity of this design, which is undoubtedly the most original since the Model T Ford". In 2011, The Globe and Mail called it a "car like no other". The motoring writer L. J. K. Setright described the 2CV as "the most intelligent application of minimalism ever to succeed as a car", and a car of "remorseless rationality".

Scottish people

The Scottish people (Scots: Scots Fowk, Scottish Gaelic: Albannaich), or Scots, are a nation and ethnic group native to Scotland. Historically, they emerged from an amalgamation of two Celtic-speaking peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or Alba) in the 9th century. Later, the neighbouring Celtic-speaking Cumbrians, as well as Germanic-speaking Anglo-Saxons and Norse, were incorporated into the Scottish nation. In modern usage, "Scottish people" or "Scots" is used to refer to anyone whose linguistic, cultural, family ancestral or genetic origins are from Scotland. The Latin word Scoti originally referred to the Gaels, but came to describe all inhabitants of Scotland. Considered archaic or pejorative, the term Scotch has also been used for Scottish people, primarily outside Scotland. John Kenneth Galbraith in his book The Scotch (Toronto: MacMillan, 1964) documents the descendants of 19th-century Scottish pioneers who settled in Southwestern Ontario and affectionately referred to themselves as 'Scotch'. He states the book was meant to give a true picture of life in the community in the early decades of the 20th century. People of Scottish descent live in many countries other than Scotland. Emigration, influenced by factors such as the Highland and Lowland Clearances, Scottish participation in the British Empire, and latterly industrial decline and unemployment, have resulted in Scottish people being found throughout the world. Scottish emigrants took with them their Scottish languages and culture. Large populations of Scottish people settled the new-world lands of North and South America, Australia and New Zealand. Canada has the highest level of Scottish descendants per capita in the world and the second-largest population of Scottish descendants, after the United States. Scotland has seen migration and settlement of many peoples at different periods in its history. The Gaels, the Picts and the Britons have their respective origin myths, like most medieval European peoples. Germanic peoples, such as the Anglo-Saxons, arrived beginning in the 7th century, while the Norse settled parts of Scotland from the 8th century onwards. In the High Middle Ages, from the reign of David I of Scotland, there was some emigration from France, England and the Low Countries to Scotland. Some famous Scottish family names, including those bearing the names which became Bruce, Balliol, Murray and Stewart came to Scotland at this time. Today Scotland is one of the countries of the United Kingdom, and the majority of people living there are British citizens.
