The Modulor
The Modulor is an anthropometric scale of proportions devised by the Swiss-born French architect Le Corbusier (1887–1965). It was developed as a visual bridge between two incompatible scales, the Imperial and the metric systems. It is based on the height of a man with his arm raised. The Modulor considered the standard human height as 1.83 m, excluding feminine measures. The dimensions were refined with overall height of raised arm set at 2.26 m. It was used as a system to set out a number of Le Corbusier's buildings and was later codified into two books. History Le Corbusier developed the Modulor in the long tradition of Vitruvius, Leonardo da Vinci's Vitruvian Man, the work of Leon Battista Alberti, and other attempts to discover mathematical proportions in the human body and then to use that knowledge to improve both the appearance and function of architecture. The system is inspired by but does not exactly correspond to human measurements, and it also draws inspiratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibonacci Numbers
In mathematics, the Fibonacci sequence is a sequence in which each element is the sum of the two elements that precede it. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted . Many writers begin the sequence with 0 and 1, although some authors start it from 1 and 1 and some (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the sequence begins : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... The Fibonacci numbers were first described in Indian mathematics as early as 200 BC in work by Pingala on enumerating possible patterns of Sanskrit poetry formed from syllables of two lengths. They are named after the Italian mathematician Leonardo of Pisa, also known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book . Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the '' Fibonacci Quarterly''. Applications of Fibon ...

Tennessee Valley Authority
The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth-largest power supplier and largest public utility in the country. The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region that had suffered from lack of infrastructure and even more extensive poverty during the Great Depression than other regions of the nation. TVA was envisioned both as a power supplier and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David E
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; pa ...

Liberty Ship
Liberty ships were a ship class, class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. The Liberty ship was effectively superseded by the Victory ship, a somewhat larger, materially faster, more modern-powered vessel of generally similar design. Over 500 were built between 1943 and 1945. Liberty ship production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types duri ...

Kaiser Shipyard
The Kaiser Shipyards were seven major shipbuilding yards located on the United States west coast during World War II. Kaiser ranked 20th among U.S. corporations in the value of wartime production contracts. The shipyards were owned by the Kaiser Shipbuilding Company, a creation of American industrialist Henry J. Kaiser (1882–1967), who established the shipbuilding company around 1939 in order to help meet the construction goals set by the United States Maritime Commission for merchant shipping. Four of the Kaiser Shipyards were located in Richmond, California, and were called the Richmond Shipyards. Three other shipyards were located in the Pacific Northwest along the Columbia and Willamette rivers: the Oregon Shipbuilding Corporation and the Swan Island Shipyard in Portland, Oregon, and the Vancouver Shipyard in Vancouver, Washington. Henry Kaiser was known for developing new methods of shipbuilding, which allowed his yards to outproduce other similar facilities and bu ...

Henry J
The Henry J is an American automobile built by the Kaiser-Frazer Corporation and named after its chairman, Henry J. Kaiser. Mass production, Production of six-cylinder models began in their Willow Run factory in Michigan in July 1950, and four-cylinder production started shortly after Labor Day, 1950. The official public introduction was on September 28, 1950, and the car was marketed until 1954. Development The Henry J was the idea of Henry J. Kaiser, who sought to increase sales of his Kaiser automotive line by adding a car that could be built inexpensively and thus affordable for the average American in the same vein that Henry Ford produced the Model T. The goal was to attract "less affluent buyers who could only afford a used car", and the attempt became a pioneering American compact car. The Kaiser-Frazer Corporation received a federal government loan in 1949 to finance the project. This monetary support specified various particulars of the vehicle. Kaiser-Frazer would ...

Metre
The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of of a second, where the second is defined by a hyperfine transition frequency of caesium. The metre was originally defined in 1791 by the French National Assembly as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's polar circumference is approximately . In 1799, the metre was redefined in terms of a prototype metre bar. The bar used was changed in 1889, and in 1960 the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digit (length)
The digit or finger is an ancient and obsolete non- SI unit of measurement of length. It was originally based on the breadth of a human finger. It was a fundamental unit of length in the Ancient Egyptian, Mesopotamian, Hebrew, Ancient Greek and Roman systems of measurement. In astronomy a digit is one twelfth of the diameter of the sun or the moon. History Ancient Egypt The digit, also called a finger or fingerbreadth, is a unit of measurement originally based on the breadth of a human finger. In Ancient Egypt it was the basic unit of subdivision of the cubit. On surviving Ancient Egyptian cubit-rods, the royal cubit is divided into seven palms of four digits or fingers each. The royal cubit measured approximately 525 mm, so the length of the ancient Egyptian digit was about 19 mm. Mesopotamia In the classical Akkadian Empire system instituted in about 2250 BC during the reign of Naram-Sin, the finger was one-thirtieth of a cubit length. The cubit was equival ...
