Extractions: Next: Minimal Surfaces Up: Manifolds Previous: Viewing with 4D Mathematicians in the nineteenth century showed that it was possible to create consistent geometries in which Euclid's Parallel Postulate was no longer true- Absence of parallels leads to spherical, or elliptic, geometry; abundance of parallels leads to hyperbolic geometry. By mid-century the English mathematician Arthur Cayley had constructed analytic models of these three geometries that had a common descent from projective geometry, which one may think of as the formalization of the renaissance theory of perspective. Cayley's construction is in fact ideal for programming interactive navigations of nonEuclidean geometries Many manifolds are naturally suited for hyperbolic or spherical, rather than Euclidean, geometry. Although the formulas for computing distance and angles in these geometries differ from Euclidean geometry, they can be built into mathematical visualization systems by hand. Translations, rotations, and dot-products for shaders and illumination must also be handled differently in the non-Euclidean geometries. In Figure , we see a partial tessellation of regular right-angled dodecahedra in the three built-in Geomview models of hyperbolic 3-space. In the virtual model shown in Figure

Euclidean & Non Euclidean Geometry
EUCLIDEAN NONeuclidean geometry. Before I address the topic of euclidean geometry, I d like to try to clarify exactly what euclidean geometry is.
http://dsdk12.net/project/euclid/GEOEUC~1.HTM

Extractions: Most of us are familiar with the term geometry. The only real difference between one high-schooler and another's opinion on geometry is the connotation of the word. It may be interesting to know for someone whose knowledge on geometery comes only fro m the course they took in high school that what they learned to be a straight line is curved in other types of geometry. These types of geometry are called non-Euclidean because they do not follow the rules that were concretely established in Euclid's El ements. Before I address the topic of Euclidean geometry, I'd like to try to clarify exactly what Euclidean geometry is. Euclidean geometry consists of all the known rules, definitions, propositions, and thereoms before and up to the time of the Greek scholar Euclid. Euclid compiled all of this information into a thirteen-volume set of books entitled Euclid's Elements. The books start with those studies of Pythagoras. Of course, Pythagoras' most known contribution to geometry is the Pythagoram Thereom - a2 + b2 = c2. Other mathematicians whose studies are found in the Elements are Apollonius, who contributed to conics, and Archimedes, who gave his knowledge of mechanics and the areas of circles. I think the best way to describe Euclidean geometry is to say that it is all based on the daily human perception of the world, and with the relationship between objects. For example, if I am standing on a floor in school, it is a given that the floor is level. If I am looking at a desktop parallel to the floor then one can only draw the assumption that the desktop is also level. I drew all of these assumptions based on the location and relativity of the objects near me. If I take a ruler and lay it on its side on a desktop, and they align, the desktop is straight. Straight is known also as a 180 degree angle.
Euclidean Geometry
euclidean geometry. Modern Concept of euclidean geometry. Today euclidean geometry is usually constructed rather than axiomatized, by means of analytic geometry.
http://www.fact-index.com/e/eu/euclidean_geometry.html

Extractions: Main Page See live article Alphabetical index Euclidean geometry , also called " flat " or " parabolic " geometry, is named after the Greek mathematician Euclid . Euclid's text Elements is an early systematic treatment of this kind of geometry , based on axioms (or postulates ). This is the kind of geometry familiar to most people, since it is the kind usually taught in high school This system is an axiomatic system , which hoped to prove all the "true statements" as theorems in geometry from a set of finite number of axioms The five postulates/axioms of the Euclidean system are: Euclidean geometry is distinguished from other geometries by the parallel postulate , which is more easily phrased as follows Through a point not on a given straight line, one and only one line can be drawn that never meets the given line.
Non-Euclidean Geometry
Noneuclidean geometry. The term non-euclidean geometry describes both hyperbolic and elliptic geometry, which are contrasted with euclidean geometry.
http://www.fact-index.com/n/no/non_euclidean_geometry_1.html

Extractions: 5 See also The term non-Euclidean geometry describes both hyperbolic and elliptic geometry , which are contrasted with Euclidean geometry . The essential difference between Euclidean and non-Euclidean geometry is the nature of parallel lines. In Euclidean geometry, if we start with a point A and a line l , then we can only draw one line through A that is parallel to l . In hyperbolic geometry, by contrast, there are infinitely many lines through A parallel to l , and in elliptic geometry, parallel lines do not exist. (See the entries on hyperbolic geometry and elliptic geometry for more information.) Another way to describe the differences between these geometries is as follows: consider two lines in a plane that are both perpendicular to a third line. In Euclidean and hyperbolic geometry, the two lines are then parallel. In Euclidean geometry, however, the lines remain at a constant distance , while in hyperbolic geometry they "curve away" from each other, increasing their distance as one moves farther from the point of intersection with the common perpendicular. In elliptic geometry, the lines "curve toward" each other, and eventually intersect; therefore no parallel lines exist in elliptic geometry.

http://math.youngzones.org/Non-Egeometry/

Extractions: Euclidean Geometry Euclid (~ 325 to ~265 BC) is called the Father of Geometry, not because he invented it, but because his book Elements is the oldest geometry text we have in the western world today. Euclid believed each part of geometry should be based on previously proven parts. However, something has to be the starting point, and he proposed four undefined terms and five basic axioms. The rest of Euclidean geometry is based upon these basic building blocks. The fifth axiom, called the parallel postulate , has been very controversial. More complex than the other four, many mathematicians tried to prove it using the other axioms. Failure to do so developed into the existence of non-Euclidean geometries.

http://www.lovely.clara.net/hawkins.html

Extractions: crop circles, Gerald Hawkins, diatonic ratios, Euclid, crop circles Several years ago, astronomer Gerald S. Hawkins, former Chairman of the astronomy department at Boston University, noticed that some of the most visually striking of the crop-circle patterns embodied geometric theorems that express specific numerical relationships among the areas of various circles, triangles, and other shapes making up the patterns (Science News: 2/1/92, p. 76). In one case, for example, an equilateral triangle fitted snugly between an outer and an inner circle. It turns out that the area of the outer circle is precisely four times that of the inner circle. Three other patterns also displayed exact numerical relationships, all of them involving a diatonic ratio , the simple whole-number ratios that determine a scale of musical notes. "These designs demonstrate the remarkable mathematical ability of their creators," Hawkins comments. Hawkins found that he could use the principles of Euclidean geometry to prove four theorems derived from the relationships among the areas depicted in crop circles. He also discovered a fifth, more general theorem, from which he could derive the other four ( see diagram, left

Extractions: Geometry provides students with a way to link their perceptions of the world with the mathematics that allow them to solve a variety of problems they will encounter not only in other disciplines but also in their lives. Geometry gives students a visual way to conceptualize or organize certain aspects of their environment, whereas algebra provides the tools for dealing with the quantitative aspects of their environment. Geometry should provide students with visual and concrete representations that help them gain insight into important areas of mathematics and their applications. The use of such tools as compass, straightedge, tracing and dot paper, mira, geoboard, calculator and computer is strongly recommended and encouraged for all geometry courses. High school geometry must extend beyond the traditional treatment of geometry as a deductive system and provide students with a broad view of geometry and its applications, including algebraic techniques associated with coordinates and transformations that reinforce important geometric concepts such as congruence, similarity, parallelism, symmetry, and perpendicularity. Thus, the integration of algebraic skills and concepts to solve geometric problems should be stressed throughout the course.

The one problem that some find with it is that it is not accurate enough to represent the three dimensional universe that we live in. It has been argued that Euclidean Geometry, while good for architecture and to survey land, when it is moved into the third dimension, the postulates do not hold up as well as those of hyperbolical and spherical geometry. Both of those geometries hold up to a two dimensional world, as well as the third dimension.

Extractions: Dictionaries: General Computing Medical Legal Encyclopedia Word: Word Starts with Ends with Definition In mathematics Mathematics is commonly defined as the study of patterns of structure, change, and space; more informally, one might say it is the study of 'figures and numbers'. In the formalist view, it is the investigation of axiomatically defined abstract structures using logic and mathematical notation; other views are described in Philosophy of mathematics. Mathematics might be seen as a simple extension of spoken and written languages, with an extremely precisely defined vocabulary and grammar, for the purpose of describing and exploring physical and conceptual relationships. Click the link for more information. Euclidean geometry is the familiar kind of geometry on the plane or in three dimensions. Mathematicians sometimes use the term to encompass higher dimensional geometries with similar properties. Euclidean geometry usually refers to geometry in the plane In mathematics, a plane is the fundamental two-dimensional object. Intuitively, it may be visualized as a flat infinite piece of paper. Most of the fundamental work in geometry, trigonometry, and graphing is performed in two dimensions, or in other words, in a plane. Given a plane, one can introduce a Cartesian coordinate system on it in order to label every point on the plane uniquely with two numbers, its coordinates.
