White House

The White House is the official residence and principal workplace of the President of the United States, located at 1600 Pennsylvania Avenue NW in Washington, D.C. It has been the residence of every U.S. president since John Adams in 1800.

The house was designed by Irish-born James Hoban and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage. However, in 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Construction continued with the addition of the South Portico in 1824 and the North in 1829.

System

A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.

Etymology

The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".

History

According to Marshall McLuhan,

"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".

In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.

Cat

The domestic cat (Felis catus or Felis silvestris catus) is a small, typically furry, domesticated, and carnivorous mammal. They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship and for their ability to hunt vermin. There are more than 70 cat breeds; different associations proclaim different numbers according to their standards. The International Progressive Cat Breeders Alliance (IPCBA) recognizes 73 cat breeds while TICA (The International Cat Association) recognizes 58, CFA (The Cat Fanciers' Association) recognizes 44 and Federation International Feline (FIFE) recognizes 43.

Cats are similar in anatomy to the other felids, with a strong, flexible body, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans. Cats, despite being solitary hunters, are a social species and cat communication includes the use of a variety of vocalizations (mewing, purring, trilling, hissing, growling, and grunting), as well as cat pheromones and types of cat-specific body language.

Jacqueline Kennedy Onassis

Jacqueline Lee "Jackie" Kennedy Onassis (née Bouvier, pronounced /ˌˈdʒækliːn ˈliː ˈbuːvieɪ/; July 28, 1929 – May 19, 1994) was the wife of the 35th President of the United States, John F. Kennedy, and First Lady of the United States during his presidency from 1961 until his assassination in 1963. Five years later, she married Greek shipping magnate Aristotle Onassis; they remained married until his death in 1975.

Jacqueline was the elder daughter of Wall Street stockbroker John Vernou Bouvier III and socialite Janet Lee Bouvier, who divorced in 1940. In 1951, she graduated with a Bachelor of Arts degree in French literature at George Washington University and went on to work for the Washington Times-Herald as an Inquiring Photographer.

In 1952, Jacqueline met Congressman John F. Kennedy at a dinner party. Shortly after, he was elected to the United States Senate and the couple married the following year. They had four children, two of whom died in infancy. As First Lady, she aided her husband's administration with her presence in social events and with her highly publicized restoration of the White House. On November 22, 1963, she was riding with her husband in a motorcade in Dallas, Texas, when he was assassinated. She and her children withdrew from public view after his funeral, and she remarried in 1968 after the assassination of Robert F. Kennedy.

Pride and Prejudice

Pride and Prejudice is a novel of manners by Jane Austen, first published in 1813. The story follows the main character, Elizabeth Bennet, as she deals with issues of manners, upbringing, morality, education, and marriage in the society of the landed gentry of the British Regency. Elizabeth is the second of five daughters of a country gentleman, Mr. Bennet living in Longbourn.

Set in England in the early 19th century, Pride and Prejudice tells the story of Mr. and Mrs. Bennet's five unmarried daughters after the rich and eligible Mr. Bingley and his status-conscious friend, Mr. Darcy, have moved into their neighbourhood. While Bingley takes an immediate liking to the eldest Bennet daughter, Jane, Darcy is disdainful of local society and repeatedly clashes with the lively second-eldest Bennet daughter, Elizabeth.

Pride and Prejudice retains a fascination for modern readers, continuing near the top of lists of "most loved books." It has become one of the most popular novels in English literature, selling over 20 million copies, and receives considerable attention from literary scholars. Modern interest in the book has resulted in a number of dramatic adaptations and an abundance of novels and stories imitating Austen's memorable characters or themes.
