A0 Paper Size ISO 216 ISO 216 specifies international standard (ISO) paper sizes used in most countries in the world today, although not in Canada, the United States, Mexico, or the Dominican Republic. The standard defines the "A" and "B" series of paper sizes, including A4, the most commonly available size. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 ISO 269 "C" series is commonly listed alongside the A and B sizes. All ISO 216, ISO 217 and ISO 269 ISO 269 paper sizes (except some envelopes) have the same aspect ratio, √2:1, within rounding to millimetres. This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio [...More...]  "A0 Paper Size" on: Wikipedia Yahoo Parouse

Mathematics Of Paper Folding The art of origami or paper folding has received a considerable amount of mathematical study. Fields of interest include a given paper model's flatfoldability (whether the model can be flattened without damaging it) and the use of paper folds to solve mathematical equations.Contents1 History 2 Pure origami2.1 Flat folding 2.2 Huzita–Hatori axioms3 Constructions3.1 Haga's theorems 3.2 Doubling the cube 3.3 Trisecting an angle4 Related problems 5 See also 6 Notes and references 7 Further reading 8 External linksHistory[edit] In 1893, Indian mathematician T. Sundara Rao published "Geometric Exercises in Paper Folding" which used paper folding to demonstrate proofs of geometrical constructions.[1] This work was inspired by the use of origami in the kindergarten system. This book had an approximate trisection of angles and implied construction of a cube root was impossible. In 1936 Margharita P [...More...]  "Mathematics Of Paper Folding" on: Wikipedia Yahoo Parouse 

Silver Ratio In mathematics, two quantities are in the silver ratio (also silver mean or silver constant) if the ratio of the sum of the smaller and twice the larger of those quantities, to the larger quantity, is the same as the ratio of the larger one to the smaller one (see below). This defines the silver ratio as an irrational mathematical constant, whose value of one plus the square root of 2 is approximately 2.4142135623. Its name is an allusion to the golden ratio; analogously to the way the golden ratio is the limiting ratio of consecutive Fibonacci numbers, the silver ratio is the limiting ratio of consecutive Pell numbers [...More...]  "Silver Ratio" on: Wikipedia Yahoo Parouse 

ISO 128 ISO 128 ISO 128 is an international standard (ISO), about the general principles of presentation in technical drawings, specifically the graphical representation of objects on technical drawings.[1]Contents1 Overview 2 Composition of ISO 128 3 Other ISO standards related to technical drawing 4 See also 5 ReferencesOverview[edit] Since 2003 the ISO 128 ISO 128 standard contains twelve parts, which were initiated between 1996 and 2003. It starts with a summary of the general rules for the execution and structure of technical drawings. Further it describes basic conventions for lines, views, cuts and sections, and different types of engineering drawings, such as those for mechanical engineering, architecture, civil engineering, and shipbuilding [...More...]  "ISO 128" on: Wikipedia Yahoo Parouse 

ANSI/ASME Y14.1 In 1992, the American National Standards Institute American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format[1] which defined a regular series of paper sizes based upon the de facto standard 8 1⁄2 in × 11 in "letter" size which it assigned "ANSI A". This series also includes "ledger"/"tabloid" as "ANSI B". This series is somewhat similar to the ISO 216 ISO 216 standard in that cutting a sheet in half would produce two sheets of the next smaller size. Unlike the ISO standard, however, the arbitrary aspect ratio forces this series to have two alternating aspect ratios. ANSI/ASME Y14.1 ANSI/ASME Y14.1 has been revised or updated in 1995, 2005 and 2012 [...More...]  "ANSI/ASME Y14.1" on: Wikipedia Yahoo Parouse 

Paper Density Paper Paper density is its mass per unit volume. "ISO 534:2011, Paper Paper and board — Determination of thickness, density and specific volume", indicates it is expressed in grams per cubic centimeter.[1] The density can be calculated by dividing the grammage of paper by its caliper.[2] See also[edit]DensityArea density Linear densityReferences[edit]^ "ISO 534:2011(en) Paper Paper and board — Determination of thickness, density and specific volume". ^ "Structural Characteristics of Paper" (PDF).

University Of Cambridge The University of Cambridge Cambridge (informally Cambridge Cambridge University)[note 1] is a collegiate public research university in Cambridge, England. Founded in 1209 and granted a royal charter by King Henry III in 1231, Cambridge Cambridge is the secondoldest university in the Englishspeaking world and the world's fourtholdest surviving university.[8] The university grew out of an association of scholars who left the University of Oxford University of Oxford after a dispute with the townspeople.[9] The two medieval universities share many common features and are often referred to jointly as "Oxbridge" [...More...]  "University Of Cambridge" on: Wikipedia Yahoo Parouse

± The plusminus sign (±) is a mathematical symbol with multiple meanings.In mathematics, it generally indicates a choice of exactly two possible values, one of which is the negation of the other. In experimental sciences, the sign commonly indicates the confidence interval or error in a measurement, often the standard deviation or standard error.[1] The sign may also represent an inclusive range of values that a reading might have. In engineering the sign indicates the tolerance, which is the range of values that are considered to be acceptable, safe, or which comply with some standard, or with a contract.[2] In botany it is used in morphological descriptions to notate "more or less". In chemistry the sign is used to indicate a racemic mixture. In chess, the sign indicates a clear advantage for the white player; the complementary sign ∓ indicates the same advantage for the black player.[3]The sign is normally pronounced "plus or minus".Contents1 History 2 [...More...]  "±" on: Wikipedia Yahoo Parouse
