'My', in English, is the genitive form of I (pronoun), or the first-person, possessive determiner.
A book is a series of pages assembled for easy portability and reading, as well as the composition contained in it. The book's most common modern form is that of a codex volume consisting of rectangular paper pages bound on one side, with a heavier cover and spine, so that it can fan open for reading. Books have taken other forms, such as scrolls, leaves on a string, or strips tied together; and the pages have been of parchment, vellum, papyrus, bamboo slips, palm leaves, silk, wood, and other materials.
The contents of books are also called books, as are other compositions of that length. For instance, Aristotle's Physics, the constituent sections of the Bible, and even the Egyptian Book of the Dead are called books independently of their physical form. Conversely, some long literary compositions are divided into books of varying sizes, which typically do not correspond to physically bound units. This tradition derives from ancient scroll formats, where long works needed several scrolls. Where very long books in codex format still need to be physically divided, the term volume is now normally used. Books may be distributed in electronic form as e-books and other formats. A UNESCO conference in 1964 attempted to define a book for library purposes as "a non-periodical printed publication of at least forty-nine pages, exclusive of cover pages". A single sheet within a codex book is a leaf, and each side of a leaf is a page. Writing or images can be printed or drawn on a book's pages.
In library and information science, a monograph is a book of one or more volumes which is not a serial such as a magazine, journal, or newspaper. An avid reader or collector of books or a book lover is a bibliophile or colloquially, "bookworm". A shop where books are bought and sold is a bookshop or bookstore. Books are also sold elsewhere. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 distinct titles had been published. In some wealthier nations, the sale of printed books has decreased because of the use of e-books, though sales of e-books declined in the first half of 2015.
40 (forty) is the natural number following 39 and preceding 41.
Though the word is related to “four”, the spelling “forty” replaced “fourty” in the course of the 17th century and is now the standard form.
In any of several studies that treat the use of signs—for example, in linguistics, logic, mathematics, semantics, and semiotics—the extension of a concept, idea, or signconsists of the things to which it applies, in contrast with its comprehension or intension, which consists very roughly of the ideas, properties, or corresponding signs that are implied or suggested by the concept in question.
In philosophical semantics or the philosophy of language, the ‘extension’ of a concept or expression is the set of things it extends to, or applies to, if it is the sort of concept or expression that a single object by itself can satisfy. Concepts and expressions of this sort are monadic or “one-place” concepts and expressions.
So the extension of the word “dog” is the set of all (past, present and future) dogs in the world: the set includes Fido, Rover, Lassie, Rex, and so on. The extension of the phrase “Wikipedia reader” includes each person who has ever read Wikipedia, including you.
The extension of a whole statement, as opposed to a word or phrase, is defined (since Frege 1892) as its truth value. So the extension of “Lassie is famous” is the logical value ‘true’, since Lassie is famous.
Some concepts and expressions are such that they don’t apply to objects individually, but rather serve to relate objects to objects. For example, the words “before” and “after” do not apply to objects individually—it makes no sense to say “Jim is before” or “Jim is after”—but to one thing in relation to another, as in “The wedding is before the reception” and “The reception is after the wedding”. Such “relational” or “polyadic” (“many-place”) concepts and expressions have, for their extension, the set of all sequences of objects that satisfy the concept or expression in question. So the extension of “before” is the set of all (ordered) pairs of objects such that the first one is before the second one.
2017 (MMXVII) was a common year starting on Sunday of the Gregorian calendar, the 2017th year of the Common Era (CE) and Anno Domini (AD) designations, the 17th year of the 3rd millennium, the 17th year of the 21st century, and the 8th year of the 2010s decade.
Berlin (/bɜːrˈlɪn/; German pronunciation: [bɛɐ̯ˈliːn]) is the capital and the largest city of Germany, as well as one of its 16 constituent states. With a steadily growing population of approximately 3.7 million, Berlin is the second most populous city proper in the European Union behind London and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of the rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has roughly 6 million residents. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers, canals and lakes.
First documented in the 13th century and situated at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg (1417–1701), the Kingdom of Prussia (1701–1918), the German Empire (1871–1918), the Weimar Republic (1919–1933), and the Third Reich (1933–1945). Berlin in the 1920s was the third largest municipality in the world. After World War II and its subsequent occupation by the victorious countries, the city was divided; West Berlin became a de facto West German exclave, surrounded by the Berlin Wall (1961–1989) and East German territory. East Berlin was declared capital of East Germany, while Bonn became the West German capital. Following German reunification in 1990, Berlin once again became the capital of all of Germany.
