United States Naval Academy
The United States Naval Academy (US Naval Academy, USNA, or Navy) is a federal service academy in Annapolis, Maryland. It was established on 10 October 1845 during the tenure of George Bancroft as Secretary of the Navy. The Naval Academy is the second oldest of the five U.S. service academies and it educates midshipmen for service in the officer corps of the United States Navy and United States Marine Corps. The campus is located on the former grounds of Fort Severn at the confluence of the Severn River and Chesapeake Bay in Anne Arundel County, east of Washington, D.C., and southeast of Baltimore. The entire campus, known colloquially as the Yard, is a National Historic Landmark and home to many historic sites, buildings, and monuments. It replaced Philadelphia Naval Asylum, in Philadelphia, that had served as the first United States Naval Academy from 1838 to 1845, when the Naval Academy formed in Annapolis. Candidates for admission generally must apply directly t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Sumter
Fort Sumter is a sea fort built on an artificial island protecting Charleston, South Carolina from naval invasion. Its origin dates to the War of 1812 when the British invaded Washington by sea. It was still incomplete in 1861 when the Battle of Fort Sumter began the American Civil War. It was severely damaged during the war, left in ruins, and although there was some rebuilding, the fort as conceived was never completed. Since the middle of the 20th century, Fort Sumter has been open to the public as part of the Fort Sumter and Fort Moultrie National Historical Park, operated by the National Park Service. The building of Fort Sumter Named after General Thomas Sumter, a Revolutionary War hero, Fort Sumter was built after the 1814 Burning of Washington during the War of 1812 as one of the third system of U.S. fortifications, to protect American harbors from foreign invaders such as Britain. Built on an artificial island in the middle of the channel that provides Charlesto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confederate States Of America
The Confederate States of America (CSA), commonly referred to as the Confederate States or the Confederacy was an unrecognized breakaway republic in the Southern United States that existed from February 8, 1861, to May 9, 1865. The Confederacy comprised U.S. states that declared secession and warred against the United States during the American Civil War: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. Kentucky and Missouri also declared secession and had full representation in the Confederate Congress, though their territory was largely controlled by Union forces. The Confederacy was formed on February 8, 1861, by seven slave states: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas. All seven were in the Deep South region of the United States, whose economy was heavily dependent upon agriculture—particularly cotton—and a plantation system that relied upon enslaved ...

Steam Engineering
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

New York Navy Yard
The Brooklyn Navy Yard (originally known as the New York Navy Yard) is a shipyard and industrial complex located in northwest Brooklyn in New York City, New York (state), New York. The Navy Yard is located on the East River in Wallabout Bay, a semicircular bend of the river across from Lower East Side#Corlears Hook, Corlears Hook in Manhattan. It is bounded by Navy Street to the west, Flushing Avenue to the south, Kent Avenue to the east, and the East River on the north.

Sighting A Gun Aboard USS Thomas Freeborn, 1861
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collabo ...

Philadelphia Navy Yard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steamboat
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...
