Sultana (steamboat)
''Sultana'' was a commercial side-wheel steamboat which exploded and sank on the Mississippi River on April 27, 1865, killing 1,169 people in what remains the worst maritime disaster in United States history. Constructed of wood in 1863 by the John Litherbury Boatyard in Cincinnati, Ohio, ''Sultana'' was intended for the lower Mississippi cotton trade. The steamer registered 1,719 tons and normally carried a crew of 85. For two years, she ran a regular route between St. Louis and New Orleans and was frequently commissioned to carry troops during the American Civil War. Although designed with a capacity of only 376 passengers, she was carrying 2,130 when three of the boat's four boilers exploded and caused it to sink near Memphis, Tennessee. The disaster was overshadowed in the press by events surrounding the end of the Civil War, including the killing of President Abraham Lincoln's assassin John Wilkes Booth just the day before. No one was ever held accountable for the tragedy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Wilkes Booth
John Wilkes Booth (May 10, 1838 – April 26, 1865) was an American stage actor who assassinated United States President Abraham Lincoln at Ford's Theatre in Washington, D.C., on April 14, 1865. A member of the prominent 19th-century Booth theatrical family from Maryland, he was a noted actor who was also a Confederate sympathizer; denouncing President Lincoln, he lamented the recent abolition of slavery in the United States. Originally, Booth and his small group of conspirators had plotted to kidnap Lincoln to aid the Confederate cause. They later decided to murder him, as well as Vice President Andrew Johnson and Secretary of State William H. Seward. Although its Army of Northern Virginia, commanded by General Robert E. Lee, had surrendered to the Union Army four days earlier, Booth believed that the Civil War remained unresolved because the Confederate Army of General Joseph E. Johnston continued fighting. Booth shot President Lincoln once in the back of the head. Lincoln' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assassination Of Abraham Lincoln
On April 14, 1865, Abraham Lincoln, the 16th president of the United States, was assassinated by well-known stage actor John Wilkes Booth, while attending the play ''Our American Cousin'' at Ford's Theatre in Washington, D.C. Shot in the head as he watched the play, Lincoln died the following day at 7:22 am in the Petersen House opposite the theater. He was the first U.S. president to be assassinated, with his funeral and burial marking an extended period of national mourning. Occurring near the end of the American Civil War, Lincoln's assassination was part of a larger conspiracy intended by Booth to revive the Confederate cause by eliminating the three most important officials of the United States government. Conspirators Lewis Powell and David Herold were assigned to kill Secretary of State William H. Seward, and George Atzerodt was tasked with killing Vice President Andrew Johnson. Beyond Lincoln's death, the plot failed: Seward was only wounded, and Johnson's wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
President Of The United States
The president of the United States (POTUS) is the head of state and head of government of the United States of America. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. The power of the presidency has grown substantially since the first president, George Washington, took office in 1789. While presidential power has ebbed and flowed over time, the presidency has played an increasingly strong role in American political life since the beginning of the 20th century, with a notable expansion during the presidency of Franklin D. Roosevelt. In contemporary times, the president is also looked upon as one of the world's most powerful political figures as the leader of the only remaining global superpower. As the leader of the nation with the largest economy by nominal GDP, the president possesses significant domestic and international hard and soft power. Article II of the Constitution establ ...

Cairo, Illinois
Cairo ( ) is the southernmost city in Illinois and the county seat of Alexander County. The city is located at the confluence of the Ohio and Mississippi rivers.

Cairo has the lowest elevation of any location in Illinois and is the only Illinois city to be surrounded by levees. It is in the area of Southern Illinois known as Little Egypt, for which the city is named after Egypt's capital. Several blocks in the town comprise the Cairo Historic District, listed on the National Register of Historic Places (NRHP). The Old Customs House is also on the NRHP.

It is the definite article in English. ''The'' is the Most common words in English, most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers.

Fatigue (material)
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting t ...

Steam Boiler
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. Type ...

Paddle Wheel
A paddle wheel is a form of waterwheel or impeller in which a number of paddles are set around the periphery of the wheel. It has several uses, of which some are: * Very low-lift water pumping, such as flooding paddy fields at no more than about height above the water source. * To move and mix algae culture in the raceway ponds used for algaculture. * Propulsion of watercraft (as a paddlewheel) * Low head hydro power (as a waterwheel) * Flow sensors * Aerators The paddle wheel is an ancient invention but is still used today in a wide range of industrial and agriculture applications. Ship propulsion Paddle wheels would enable ships to travel without needing wind or oars. They were made obsolete by propellers, which had greater propulsion with lower weight and fuel usage. This was demonstrated by an 1845 tug-of-war competition between and with the screw-driven ''Rattler'' pulling the paddle steamer ''Alecto'' backward at .
