France In The Nineteenth Century
In the history of France, the period from 1789 to 1914, dubbed the " long 19th century" by the historian Eric Hobsbawm, extends from the French Revolution to the brink of World War I. Throughout this period, France underwent significant transformations that reshaped its geography, demographics, language, and economic landscape, marking a period of profound change and development. The French Revolution and Napoleonic eras fundamentally altered French society, promoting centralization, administrative uniformity across departments, and a standardized legal code. Education also centralized, emphasizing technical training and meritocracy, despite growing conservatism among the aristocracy and the church. Wealth concentration saw the richest 10 percent owning most of the nation's wealth. The 19th century saw France expanding to nearly its modern territorial limits through annexations and overseas imperialism, notably in Algeria, Indochina, and Africa. Despite territorial gains, Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballast Tanks
A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging stresses, or to increase draft, as in a semi-submersible vessel or platform, or a SWATH, to improve seakeeping. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels, and makes it easy for the crew to reduce a vessel's draft when it enters shallower water, by temporarily pumping out ballast. Airships use ballast tanks mainly to control buoyancy and correct trim. History The concept of ballast tanks, inspired by nature, can be seen in aquatic life forms like blowfish and the argonaut octopus, which regulate their buoyancy to move and survive in water. Humans have adapted and refined thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Delaware River
The Delaware River is a major river in the Mid-Atlantic region of the United States and is the longest free-flowing (undammed) river in the Eastern United States. From the meeting of its branches in Hancock, New York, the river flows for along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay. The river has been recognized by the National Wildlife Federation as one of the country's Great Waters and has been called the "Lifeblood of the Northeast" by American Rivers. Its watershed drains an area of and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct. The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genius
Genius is a characteristic of original and exceptional insight in the performance of some art or endeavor that surpasses expectations, sets new standards for the future, establishes better methods of operation, or remains outside the capabilities of competitors. Genius is associated with intellectual ability and creative productivity. The term ''genius'' can also be used to refer to people characterised by genius, and/or to polymaths who excel across many subjects. There is no scientifically precise definition of genius. When used to refer to the characteristic, genius is associated with talent, but several authors such as Cesare Lombroso and Arthur Schopenhauer systematically distinguish these terms. Walter Isaacson, biographer of many well-known geniuses, explains that although high intelligence may be a prerequisite, the most common trait that actually defines a genius may be the extraordinary ability to apply creativity and imaginative thinking to almost any situation. ...
