Question: The Algonquins are indigenous inhabitants of North America who speak the Algonquin language, a divergent dialect of the Ojibwe language, which is part of the Algonquian language family. Culturally and linguistically, they are closely related to the Odawa and Ojibwe, with whom they form the larger Anicinape (Anishinaabe) grouping. The Algonquin people call themselves Omamiwinini (plural: Omamiwininiwak) or the more generalised name of Anicinape. Though known by several names in the past, the most common term "Algonquin" has been suggested to derive from the Maliseet word elakomkwik (IPA: [elae'gomogwik]): "they are our relatives/allies".

The Algonquin first met Europeans when Samuel de Champlain came upon a party led by the Kitcisipirini Chief Tessouat at Tadoussac, in eastern present-day Quebec, in the summer of 1603. They were celebrating a recent victory over the Iroquois, with the allied Montagnais and Etechemins (Malecite). Champlain did not understand that the Algonquins were socially united by a strong totem/clan system rather than the European-styled political concept of nationhood. The several Algonquin bands each had its own chief. Within each band, the chief depended on political approval from each of the band's clan leaders. Champlain needed to cultivate relationships with numerous chiefs and clan leaders. From 1603, some of the Algonquin allied with the French under Champlain. This alliance proved useful to the Algonquin, who previously had little to no access to European firearms.  Champlain made his first exploration of the Ottawa River during May 1613 and reached the fortified Kitcisipirini village at Morrison Island. Unlike the other Algonquin communities, the Kitcisipiriniwak did not change location with the seasons. They had chosen a strategic point astride the trade route between the Great Lakes and the St. Lawrence River. They prospered through the collection of beaver pelts from native traders passing through their territory. They also were proud of their corn fields.  At first, the French used the term "Algonquin" only for a second group, the Wawackeciriniwak. However, by 1615, they applied the name to all of the Algonquin bands living along the Ottawa River. Because of keen interest by tribes to gain control of the lower Ottawa River, the Kitcisipiriniwak and the Wawackeciriniwak came under fierce opposition. These two large groups allied together, under the leadership of Sachem Charles Parcharini, to maintain the Omamiwinini identity and territory.

Question: Fazlur Rahman Khan (Bengali: phjlur rhmaan khaan, Fozlur Rohman Khan) (3 April 1929 - 27 March 1982) was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center. Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century.

Khan's central innovation in skyscraper design and construction was the idea of the "tube" structural system for tall buildings, including the framed tube, trussed tube, and bundled tube variants. His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design. Most buildings over 40 stories constructed since the 1960s now use a tube design derived from Khan's structural engineering principles.  Lateral loads (horizontal forces) such as wind forces, seismic forces, etc., begin to dominate the structural system and take on increasing importance in the overall building system as the building height increases. Wind forces become very substantial, and forces caused by earthquakes, etc. are important as well. The tubular designs resist such forces for tall buildings. Tube structures are stiff and have significant advantages over other framing systems. They not only make the buildings structurally stronger and more efficient, but also significantly reduce the structural material requirements. The reduction of material makes the buildings economically more efficient and reduces environmental impact. The tubular designs enable buildings to reach even greater heights. Tubular systems allow greater interior space and further enable buildings to take on various shapes, offering added freedom to architects. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Khan was among a group of engineers who encouraged a rebirth in skyscraper construction after a hiatus of over thirty years.  The tubular systems have yet to reach their limit when it comes to height. Another important feature of the tubular systems is that buildings can be constructed using steel or reinforced concrete, or a composite of the two, to reach greater heights. Khan pioneered the use of lightweight concrete for high-rise buildings, at a time when reinforced concrete was used for mostly low-rise construction of only a few stories in height. Most of Khan's designs were conceived considering pre-fabrication and repetition of components so projects could be quickly built with minimal errors.  The population explosion, starting with the baby boom of the 1950s, created widespread concern about the amount of available living space, which Khan solved by building upward. More than any other 20th-century engineer, Fazlur Rahman Khan made it possible for people to live and work in "cities in the sky." Mark Sarkisian (Director of Structural and Seismic Engineering at Skidmore, Owings & Merrill) said, "Khan was a visionary who transformed skyscrapers into sky cities while staying firmly grounded in the fundamentals of engineering."
