Non-Euclidean (hyperbolic) Geometry Applet
Noneuclidean geometry. But, in fact, in terms of the non-euclidean geometry,despite appearances, these motions preserve distances and angles.
http://www.math.umn.edu/~garrett/a02/H2.html

Extractions: This applet allows click-and-drag drawing in the Poincare model of the (hyperbolic) non-Euclidean plane, and also motion . The circular arcs drawn by mouse drags are the geodesics (straight lines) in this model of geometry. In "move" mode, click-and-drag slides the whole picture in the direction of the mouse drag. This is analogous to ordinary "sliding" of objects in Euclidean space; however, in this non-Euclidean geometry the Euclidean picture of it makes things appear to become smaller as they move toward the edge. But, in fact, in terms of the non-Euclidean geometry, despite appearances, these motions preserve distances and angles. The preservation of angles should be detectable if one keeps in mind that the angles are angles between the arcs of circles at their point of intersection. Since the bounding circle is "infinitely far away", the motion of the picture does not exactly parallel the mouse drag motion, but instead moves about the same non-Euclidean distance as the Euclidean distance moved by the mouse. So the picture will appear to lag behind the mouse. garrett@math.umn.edu

Non-Euclidean Geometry Seminar

http://www.math.columbia.edu/~pinkham/teaching/seminars/NonEuclidean.html

Extractions: Seminar on the History of Hyperbolic Geometry Greg Schreiber In this course we traced the development of hyperbolic (non-Euclidean) geometry from ancient Greece up to the turn of the century. This was accomplished by focusing chronologically on those mathematicians who made the most significant contributions to the subject. We began with an exposition of Euclidean geometry, first from Euclid's perspective (as given in his Elements) and then from a modern perspective due to Hilbert (in his Foundations of Geometry). Almost all criticisms of Euclid up to the 19th century were centered on his fifth postulate, the so-called Parallel Postulate.The first half of the course dealt with various attempts by ancient, medieval, and (relatively) modern mathematicians to prove this postulate from Euclid's others. Some of the most noteworthy efforts were by the Roman mathematician Proclus, the Islamic mathematicians Omar Khayyam and Nasir al-Din al-Tusi, the Jesuit priest Girolamo Sacchieri, the Englishman John Wallis, and the Frenchmen Lambert and Legendre. Each one gave a flawed proof of the parallel postulate, containing some hidden assumption equivalent to that postulate. In this way properties of hyperbolic geometry were discovered, even though no one believed such a geometry to be possible. References: Four general references were used throughout this course: Bonola's Non-Euclidean Geometry, Jeremy Gray's Ideas of Space, Greenberg's Euclidean and Non-Euclidean Geometries, and McCleary's Geometry from a Differential Viewpoint. In addition, original works of these mathematicians were used whenever possible, as well as biographies of them. These books included Euclid's Elements, Hilbert's Foundations of Geometry, Proclus's A Commentary on the First Book of Euclid's Elements, Saccheri's Euclid Vindicated, Bolyai's Science of Absolute Space, Lobachevskii's Geometrical Researches in the Theory of Parallels, and Riemann's "On the Hypotheses Which Lie at the Foundations of Geometry," among others.
Euclidean & Non Euclidean Geometry
EUCLIDEAN NONeuclidean geometry. Before I address the topic of Euclideangeometry, I'd like to try to clarify exactly what euclidean geometry is.
http://www.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.

The Applications Of Noneuclidean geometry. Table of Contents. 1.Where EuclideanGeometry Is Wrong. 5.Celestial Mechanics. Where euclidean geometry Is Wrong.
http://members.tripod.com/~noneuclidean/applications.html

Extractions: Table of Contents Where Euclidean Geometry Is Wrong The Theory of General Relativity Spherical Geometry Celestial Mechanics Since Euclid first published his book Elements in 300 B.C. it has remained remarkably correct and accurate to real world situations faced on Earth. 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. Back To Top Einstein's Theory Of General Relativity is based on a theory that space is curved. The cause is explained by the theory itself. Einstein's General Theory of Relativity can be understood as saying that: Matter and energy distort space The distortions of space affect the motions of matter and energy.
What Is Non-Euclidean Geometry?
What is Noneuclidean geometry? Non l. Other than this difference, non-Euclideangeometry holds to the rest of Euclid's postulates
http://members.tripod.com/~noneuclidean/whatisit_main.html

Extractions: Non Euclidean geometry is geometry that refutes Euclid's fifth postulate: Given a point p and a line l, there is exactly one line through p that is parralel to l. Other than this difference, non-Euclidean geometry holds to the rest of Euclid's postulates: To see how this movement got started, please see the History section. Now, there are two ways that you can refute this. One way is to say: Given a line l and point p, there are no lines parralel to l through p. This leads to Spherical/Elliptical Geometry The other is to say: Given a line l and a point p, there are infinite lines through p parralel to l.

http://www.geocities.com/CapeCanaveral/7997/noneuclid.html

Extractions: Introduction: Unlike other branches of math, geometry has been connected with two purposes since the ancient Greeks. Not only is it an intellectual discipline, but also, it has been considered an accurate description of our physical space. However in order to talk about the different types of geometries, we must not confuse the term geometry with how physical space really works. Geometry was devised for practical purposes such as constructions, and land surveying. Ancient Greeks, such as Pythagoras (around 500 BC) used geometry, but the various geometric rules that were being passed down and inherited were not well connected. So around 300 BC, Euclid was studying geometry in Alexandria and wrote a thirteen-volume book that compiled all the known and accepted rules of geometry called The Elements, and later referred to as Euclids Elements. Because math was a science where every theorem is based on accepted assumptions, Euclid first had to establish some axioms with which to use as the basis of other theorems. He used five axioms as the 5 assumptions, which he needed to prove all other geometric ideas. The use and assumption of these five axioms is what it means for something to be categorized as Euclidean geometry, which is obviously named after Euclid, who literally wrote the book on geometry. The first four of his axioms are fairly straightforward and easy to accept, and no mathematician has ever seriously doubted them. The first four of Euclids axioms are:

The three buttons at the bottom of the Main panel are for setting the current geometry type. In each of the three geometries, three models are supported: Virtual Projective , and Conformal . You can change the current model with the Model browser on the Camera panel. Each Geomview camera has its own model setting. The default model is all three spaces is Virtual . This corresponds to the camera being in the same space as, and moving under the same set of transformations as, the geometry itself. In Euclidean space Virtual is the most useful model. The other models were implemented for hyperbolic and spherical spaces and just happen to work in Eucldiean space as well: Projective is the same as Virtual but by default displays the unit sphere, and Conformal displays everything inverted in the unit sphere. In hyperbolic space, the Projective model setting gives a view of the projective ball model of hyperbolic 3-space imbedded in Euclidean space. The camera is initially outside the unit ball. In this model, the camera moves by Euclidean motions and geometry moves by hyperbolic motions. Conformal model is similar but shows the conformal ball model instead.

http://www.infoplease.com/ce6/sci/A0835830.html

Extractions: non-Euclidean geometry non-Euclidean geometry, branch of geometry in which the fifth postulate of Euclidean geometry, which allows one and only one line parallel to a given line through a given external point, is replaced by one of two alternative postulates. Allowing two parallels through any external point, the first alternative to Euclid 's fifth postulate, leads to the hyperbolic geometry developed by the Russian N. I. Lobachevsky in 1826 and independently by the Hungarian Janos Bolyai in 1832. The second alternative, which allows no parallels through any external point, leads to the elliptic geometry developed by the German Bernhard Riemann in 1854. The results of these two types of non-Euclidean geometry are identical with those of Euclidean geometry in every respect except those propositions involving parallel lines, either explicitly or implicitly (as in the theorem for the sum of the angles of a triangle).
