The Postman
''The Postman'' is a post-apocalyptic dystopia science fiction novel by David Brin. It is about a man wandering the desolate Oregon countryside who finds a United States Postal Service uniform, which he puts on and then claims he is a mail carrier and federal inspector for the "Restored United States of America". His mail service and claims about the return of a central government gives hope to the people, who are threatened by a murderous, neo-feudalist militia. The first two parts were published separately as "The Postman" (1982) and "Cyclops" (1984). In 1997, a film adaptation of the novel was released starring Kevin Costner and Will Patton. Plot Despite the post-apocalyptic scenario and several action sequences, the book is largely about civilization and its symbols. Each of the three sections deals with a different symbol. The first is the Postman himself, Gordon Krantz, who takes the uniform solely for warmth after he loses almost everything to bandits. He wanders amo ...

Electromagnetic Pulse
An electromagnetic pulse (EMP), also a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. Depending upon the source, the origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current. The electromagnetic interference caused by an EMP disrupts communications and damages electronic equipment; at higher levels of energy, an EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering. EMP weapons are designed to deliver the damaging effects of a high-energy EMP that will disrupt unprotected infrastructure in the country, thus the employment of an EMP weapon against a country is the scenario of war most likely to collapse the functionality of the electrical network of the country. General characteristics An electrom ...

Biological War
Biological warfare, also known as germ warfare, is the use of biological toxins or infectious agents such as bacteria, viruses, insects, and fungi with the intent to kill, harm or incapacitate humans, animals or plants as an act of war. Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities ( ⁠''i.e.'' viruses, which are not universally considered "alive"). Entomological (insect) warfare is a subtype of biological warfare. Offensive biological warfare is prohibited under customary international humanitarian law and several international treaties. In particular, the 1972 Biological Weapons Convention (BWC) bans the development, production, acquisition, transfer, stockpiling and use of biological weapons. Therefore, the use of biological agents in armed conflict is a war crime. In contrast, defensive biological research for prophylactic, protective or other peaceful purposes is not proh ...

Flag Of California
The Bear Flag is the official flag of the U.S. state of California. The precursor of the flag was first flown during the 1846 Bear Flag Revolt and was also known as the Bear Flag. A predecessor, called the Lone Star Flag, was used in an 1836 independence movement; the red star element from that flag appears in the Bear Flag of today. Current flag Law and protocol The 1911 statute stated: In 1953, the design and specifications for the state flag were standardized in a bill signed by Governor Earl Warren and illustrated by Donald Graeme Kelley of Marin County, California. The California state flag is often called the "Bear Flag" and in fact, the present statute adopting the flagCalifornia Government Code § 420 states: "The Bear Flag is the State Flag of California." Pursuant tSection 439 of the California Government Code the regulations and protocols for the proper display of the flag of California is controlled by the California Adjutant General: When the flag is disp ...

Willamette Valley
The Willamette Valley ( ) is a long valley in Oregon, in the Pacific Northwest region of the United States. The Willamette River flows the entire length of the valley and is surrounded by mountains on three sides: the Cascade Range to the east, the Oregon Coast Range to the west, and the Calapooya Mountains to the south. The valley is synonymous with the cultural and political heart of Oregon and is home to approximately 70 percent of its population including the five largest cities in the state: Portland, Eugene, Salem, Gresham, and Hillsboro. The valley's numerous waterways, particularly the Willamette River, are vital to the economy of Oregon, as they continuously deposit highly fertile alluvial soils across its broad, flat plain. A massively productive agricultural area, the valley was widely publicized in the 1820s as a "promised land of flowing milk and honey." Throughout the 19th century, it was the destination of choice for the oxen-drawn wagon trains of emigr ...

Old West
The American frontier, also known as the Old West or the Wild West, encompasses the geography, history, folklore, and culture associated with the forward wave of American expansion in mainland North America that began with European colonial settlements in the early 17th century and ended with the admission of the last few western territories as states in 1912 (except Alaska, which was not admitted into the Union until 1959). This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist attitude known as "Manifest Destiny" and the historians' " Frontier Thesis". The legends, historical events and folklore of the American frontier have embedded themselves into United States culture so much so that the Old West, and the Western genre of media specifically, has become one of the defining periods of American national identity. The archetypical Old West period is generally ac ...

Umpqua Valley
The Umpqua River ( ) on the Pacific coast of Oregon in the United States is approximately long. One of the principal rivers of the Oregon Coast and known for bass and shad, the river drains an expansive network of valleys in the mountains west of the Cascade Range and south of the Willamette Valley, from which it is separated by the Calapooya Mountains. From its source northeast of Roseburg, the Umpqua flows northwest through the Oregon Coast Range and empties into the Pacific at Winchester Bay. The river and its tributaries flow almost entirely within Douglas County, which encompasses most of the watershed of the river from the Cascades to the coast. The "Hundred Valleys of the Umpqua" form the heart of the timber industry of southern Oregon, generally centered on Roseburg. The Native Americans in the Umpqua's watershed consist of several tribes, such as the Lower and Upper Umpqua (for which the river is named), and the Kalapuya. These tribes witnessed much of the Great Fl ...

Rogue River (Oregon)
The Rogue River ( tol, yan-shuu-chit’ taa-ghii~-li~’, tkm, tak-elam) in southwestern Oregon in the United States flows about in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world's best examples of rocks that form the Earth's mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of ...

Oracle At Delphi
Pythia (; grc, Πυθία ) was the name of the high priestess of the Temple of Apollo at Delphi. She specifically served as its oracle and was known as the Oracle of Delphi. Her title was also historically glossed in English as the Pythoness. The name ''Pythia'' is derived from ''Pytho'', which in myth was the original name of Delphi. Etymologically, the Greeks derived this place name from the verb () "to rot", which refers to the sickly sweet smell from the decomposing body of the monstrous Python after it was slain by Apollo. The Pythia was established at the latest in the 8th century BC, (though some estimates date the shrine to as early as 1400 BC), and was widely credited for her prophecies uttered under divine possession (enthusiasmos) by Apollo. The Pythian priestess emerged pre-eminent by the end of the 7th century BC and continued to be consulted until the late 4th century AD. During this period, the Delphic Oracle was the most prestigious and authoritative oracle ...

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...
