Adventure Fiction
Adventure fiction is a type of fiction that usually presents danger, or gives the reader a sense of excitement. Some adventure fiction also satisfies the literary definition of Romance (prose fiction)#Definition, romance fiction. History In the Introduction to the ''Encyclopedia of Adventure Fiction'', Critic Don D'Ammassa defines the genre as follows: D'Ammassa argues that adventure stories make the element of danger the focus; hence he argues that Charles Dickens's novel ''A Tale of Two Cities'' is an adventure novel because the protagonists are in constant danger of being imprisoned or killed, whereas Dickens's ''Great Expectations'' is not because "Pip's encounter with the convict is an adventure, but that scene is only a device to advance the main plot, which is not truly an adventure." Adventure has been a common theme (literature), theme since the earliest days of written fiction. Indeed, the standard plot of Romance (heroic literature), Medieval romances was a serie ...

Holography
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest.

Prisoner Of War
A prisoner of war (POW) is a person who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610. Belligerents hold prisoners of war in custody for a range of legitimate and illegitimate reasons, such as isolating them from the enemy combatants still in the field (releasing and repatriating them in an orderly manner after hostilities), demonstrating military victory, punishing them, prosecuting them for war crimes, exploiting them for their labour, recruiting or even conscripting them as their own combatants, collecting military and political intelligence from them, or indoctrinating them in new political or religious beliefs. Ancient times For most of human history, depending on the culture of the victors, enemy fighters on the losing side in a battle who had surrendered and been taken as prisoners of war could expect to be either slaughtered or enslaved.

Civil Rights Movement
The civil rights movement was a nonviolent social and political movement and campaign from 1954 to 1968 in the United States to abolish legalized institutional Racial segregation in the United States, racial segregation, Racial discrimination in the United States, discrimination, and disenfranchisement in the United States, disenfranchisement throughout the United States. The movement had its origins in the Reconstruction era during the late 19th century, although it made its largest legislative gains in the 1960s after years of direct actions and grassroots protests. The social movement's major nonviolent resistance and civil disobedience campaigns eventually secured new protections in federal law for the civil rights of all Americans. After the American Civil War and the subsequent Abolitionism in the United States, abolition of slavery in the 1860s, the Reconstruction Amendments to the United States Constitution granted emancipation and constitutional rights of citizenship ...

Orphanage
An orphanage is a Residential education, residential institution, total institution or group home, devoted to the Childcare, care of orphans and children who, for various reasons, cannot be cared for by their biological families. The parents may be deceased, absent, or abusive. There may be substance abuse or mental illness in the biological home, or the parent may simply be unwilling to care for the child. The legal responsibility for the support of abandoned children differs from country to country, and within countries. Government-run orphanages have been phased out in most developed countries during the latter half of the 20th century but continue to operate in many other regions internationally. It is now generally accepted that orphanages are detrimental to the emotional wellbeing of children, and government support goes instead towards supporting the family unit. A few large international charities continue to fund orphanages, but most are still commonly founded by sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cigar
A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. Cigars are produced in a variety of sizes and shapes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars often come with two bands, especially Cuban cigar bands, showing Limited Edition (''Edición Limitada'') bands displaying the year of production. Cigar tobacco is grown in significant quantities primarily in Central America and the islands of the Caribbean, including Cuba, the Dominican Republic, Haiti, Honduras, Mexico, Ecuador, Nicaragua, Guatemala, Costa Rica, Panama, and Puerto Rico; it is also produced in the Eastern United States, Brazil and in the Mediterranean countries of Italy and Spain (in the Canary Islands), and in Indonesia and the P ...

Promiscuity
Promiscuity is the practice of engaging in sexual activity frequently with different Sexual partner, partners or being indiscriminate in the choice of sexual partners. The term can carry a moral judgment. A common example of behavior viewed as promiscuous by many cultures is the one-night stand, and its frequency is used by researchers as a marker for promiscuity. What sexual behavior is considered promiscuous varies between cultures, as does the prevalence of promiscuity. Different standards are often applied to different genders and civil statutes. Feminism, Feminists have traditionally argued a significant double standard exists between how men and women are judged for promiscuity. Historically, stereotypes of the promiscuous woman have tended to be pejorative, such as "the slut" or "the harlot", while male stereotypes have been more varied, some expressing approval, such as "the stud" or "the player", while others imply societal deviance, such as "the womanizer" or "the philand ...

Kung Fu
Chinese martial arts, often called by the umbrella terms kung fu (; ), kuoshu () or wushu (), are multiple fighting styles that have developed over the centuries in Greater China. These fighting styles are often classified according to common traits, identified as "families" of martial arts. Examples of such traits include ''Shaolinquan'' () physical exercises involving All Other Animals () mimicry or training methods inspired by Old Chinese philosophies, religions and legends. Styles that focus on qi manipulation are called ''internal'' (; ), while others that concentrate on improving muscle and cardiovascular fitness are called ''external'' (; ). Geographical association, as in ''northern'' (; ) and ''southern'' (; ), is another popular classification method. Terminology ''Kung fu'' and ''wushu'' are loanwords from Cantonese and Mandarin respectively that, in English, are used to refer to Chinese martial arts. However, the Chinese terms ''kung fu'' and ''wushu'' (; ) ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Computing
Quantum computing is a type of computation whose operations can harness the phenomena of quantum mechanics, such as superposition, interference, and entanglement. Devices that perform quantum computations are known as quantum computers. Though current quantum computers may be too small to outperform usual (classical) computers for practical applications, larger realizations are believed to be capable of solving certain computational problems, such as integer factorization (which underlies RSA encryption), substantially faster than classical computers. The study of quantum computing is a subfield of quantum information science. There are several models of quantum computation with the most widely used being quantum circuits. Other models include the quantum Turing machine, quantum annealing, and adiabatic quantum computation. Most models are based on the quantum bit, or "qubit", which is somewhat analogous to the bit in classical computation. A qubit can be in a 1 or 0 quantum s ...

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). ...

Self-awareness
In philosophy of self, self-awareness is the experience of one's own personality or individuality. It is not to be confused with consciousness in the sense of qualia. While consciousness is being aware of one's environment and body and lifestyle, self-awareness is the recognition of that awareness. Self-awareness is how an individual consciously knows and understands their own character, feelings, motives, and desires. Neurobiological basis Introduction There are questions regarding what part of the brain allows us to be self-aware and how we are biologically programmed to be self-aware. V.S. Ramachandran has speculated that mirror neurons may provide the neurological basis of human self-awareness. In an essay written for the Edge Foundation in 2009, Ramachandran gave the following explanation of his theory: "... I also speculated that these neurons can not only help simulate other people's behavior but can be turned 'inward'—as it were—to create second-order representa ...
