Columbia (name)
Columbia (; ) is the female national personification of the United States. It was also a historical name applied to the Americas and to the New World. The association has given rise to the names of many American places, objects, institutions and companies, including the District of Columbia; Columbia, South Carolina; Columbia University; "Hail, Columbia" and ''Columbia Rediviva''; the Columbia River. Images of the Statue of Liberty (''Liberty Enlightening the World'', erected in 1886) largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. However, Columbia's most prominent display today is being part of the logo of the Hollywood film studio Columbia Pictures. ''Columbia'' is a New Latin toponym, in use since the 1730s with reference to the Thirteen Colonies which formed the United States. It originated from the name of the Genoese explorer Christopher Columbus and from the Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Washington, D
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands.

North River Steamboat
The ''North River Steamboat'' or ''North River'', colloquially known as the ''Clermont'', is widely regarded as the world's first vessel to demonstrate the viability of using steam propulsion for commercial water transportation. Built in 1807, the ''North River Steamboat'' operated on the Hudson River – at that time often known as the North River – between New York City and Albany, New York. She was built by the wealthy investor and politician Robert Livingston and inventor and entrepreneur Robert Fulton (1765–1815). Background Livingston had obtained from the New York legislature the exclusive right to steam navigation on the Hudson River. In 1803, while Livingston was Minister to France, Fulton's company built a small steamboat and tested it on the Seine. With this success, Livingston then contracted with Fulton to take advantage of his Hudson River monopoly and build a larger version for commercial service. Their larger steamer was built at the Charles Browne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Fulton
Robert Fulton (November 14, 1765 – February 24, 1815) was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the (also known as ''Clermont''). In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of , in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers. In 1800, Fulton had been commissioned by Napoleon Bonaparte, leader of France, to attempt to design a submarine; he produced , the first practical submarine in history. Fulton is also credited with inventing some of the world's earliest naval torpedoes for use by the Royal Navy.Best, Nicholas (2005).

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
