Information:  - A novel is a long narrative, normally in prose, which describes fictional characters and events, usually in the form of a sequential story.  - Fiction is the classification for any story or universe derived from imaginationin other words, not based strictly on history or fact. Fiction can be expressed in a variety of formats, including writings, live performances, films, television programs, animations, video games, and role-playing games, though the term originally and most commonly refers to the narrative forms of literature (see "literary" fiction), including the novel, novella, short story, and play. Fiction constitutes an act of creative invention, so that faithfulness to reality is not typically assumed; in other words, fiction is not expected to present only characters who are actual people or descriptions that are factually true. The context of fiction is generally open to interpretation, due to fiction's freedom from any necessary embedding in reality; however, some fictional works are claimed to be, or marketed as, historically or factually accurate, complicating the traditional distinction between fiction and non-fiction. Fiction is a classification or category, rather than a specific mode or genre, unless used in a narrower sense as a synonym for a particular literary fiction form.  - Prose is a form of language that exhibits a grammatical structure and a natural flow of speech, rather than a rhythmic structure as in traditional poetry. Where the common unit of verse is based on meter or rhyme, the common unit of prose is purely grammatical, such as a sentence or paragraph.  - `` Stellar Ships '' or `` Star Ships '' ( Russian name `` Zvezdnye Korabli '' , Russian :   ) is a short story by the Soviet writer and paleontologist Ivan Yefremov written in 1944 and first published in 1948 in the USSR . This story is about the discovery of an ancient dinosaur bone with a mysterious bullet hole ( or `` blaster hole '' ) and an alien skull and his portrait nearby . This acts as a starting point and a cover story to the philosophical idea of plurality of the mind cradles in the Universe , similarity of planet evolution paths , and similarity of physiology and psychology . Efremov states the final perspective for all civilisations is The Great Circle , which will unite them all .  - An anecdote is a brief, revealing account of an individual person or an incident. Often humorous, anecdotes differ from jokes because their primary purpose is not simply to provoke laughter, but to reveal a truth more general than the brief tale itself, such as to characterize a person by delineating a specific quirk or trait, to communicate an abstract idea about a person, place, or thing through the concrete details of a short narrative. An anecdote is "a story with a point."  - A short story is a piece of prose fiction that can be read in one sitting. Emerging from earlier oral storytelling traditions in the 17th century, the short story has grown to encompass a body of work so diverse as to defy easy characterization. At its most prototypical the short story features a small cast of named characters, and focuses on a self-contained incident with the intent of evoking a "single effect" or mood. In doing so, short stories make use of plot, resonance, and other dynamic components to a far greater degree than is typical of an anecdote, yet to a far lesser degree than a novel. While the short story is largely distinct from the novel, authors of both generally draw from a common pool of literary techniques.  - Ivan Antonovich (real patronymic Antipovich) Yefremov (April 22, 1908  October 5, 1972), last name sometimes spelled Efremov, was a Soviet paleontologist, science fiction author and social thinker. He originated taphonomy, the study of fossilization patterns.  - Storytelling is the social and cultural activity of sharing stories, often with improvisation, theatrics, or embellishment. Stories or narratives have been shared in every culture as a means of entertainment, education, cultural preservation and instilling moral values. Crucial elements of stories and storytelling include plot, characters and narrative point of view. The term 'storytelling' is used in a narrow sense to refer specifically to oral storytelling and also in a looser sense to refer to techniques used in other media to unfold or disclose the narrative of a story.
