Note: the following has been abstracted from the Grolier Encyclopedia. Euclidean Geometry Euclidean geometry is the study of points, lines, planes, and other geometric figures, using a modified version of the assumptions of Euclid (c.300 BC). The most controversial assumption has been the parallel postulate: there is one and only one line that contains a given point and is parallel to a given line. The development of Euclidean geometry extends at least from 10,000 BC to the 20th century. In the 4th century BC, Plato founded an Academy in Athens, emphasized geometry, and used the five regular Polyhedrons in his explanation of the scientific phenomena of the universe. Aristotle, a student of Plato at the Academy, identified the rules for logical reasoning. The 13 books of Euclid's Elements are based on the mathematics that was considered at Plato's Academy. The geometry in the Elements was a logical system based on ten assumptions. Five of the assumptions were called common notions (Axioms, or self-evident truths), and the other five were postulates (required conditions). The resulting logical system was taken as a model for deductive reasoning and had a profound effect on all branches of knowledge. Although it has been necessary to refine the postulates as concepts of existence, continuity, order, and other aspects of Geometry have changed, the resulting geometry is still called Euclidean geometry. Modifications of Euclid's parallel postulate provide the basis for

Note: the following has been abstracted from the Grolier Encyclopedia. Non-Euclidean Geometry Non-Euclidean Geometry Comparisons of the Geometries Historical Development The Geometry of the Universe Comparisons of the Geometries The sum of the measures of the angles of a triangle is 180 deg in Euclidean Geometry , less than 180 deg in hyperbolic geometry, and more than 180 deg in elliptic geometry. The area of a triangle in hyperbolic geometry is proportional to the deficiency of its angle sum from 180 deg, while the area of a triangle in elliptic geometry is proportional to the excess of its angle sum over 180 deg. In Euclidean geometry all triangles have an angle sum of 180 deg irrespective of area. Thus, similar triangles with different areas can exist in Euclidean geometry. This kind of occurrence is not possible in hyperbolic or elliptic geometry. In two-dimensional geometries, lines that are perpendicular to the same given line are parallel in Euclidean geometry, are neither parallel nor intersecting in hyperbolic geometry, and intersect at the pole of the given line in elliptic geometry. The appearance of the lines as straight or curved depends on the postulates for the space. Historical Development Euclid postponed the use of his parallel postulate as long as possible and probably was a bit uneasy about it. For the next 2,000 years numerous attempts were made to prove the statement as a theorem. Many of the attempts involved statements that are now recognized as equivalent to the parallel postulate. These statements include the following: (1) Parallel lines exist, and any two lines cut by a transversal are no more parallel on one side of the transversal than on the other side (2d century AD). (2) Parallel lines exist, and if a line intersects one of two parallel lines, it will intersect the other also (5th century). (3) The sum of the measures of the angles of any triangle is equal to a straight angle (13th century). (4) Given any triangle, a similar triangle of any size whatever may be constructed (17th century).

Next: Minimal Surfaces Up: Manifolds Previous: Viewing with 4D Non-Euclidean Geometry 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.

What is Non-Euclidean Geometry 1.1 Euclidean Geometry: he Geometry with which we are most familiar is called Euclidean Geometry. Euclidean Geometry was named after Euclid, a Greek mathematician who lived in 300 BC. His book, called "The Elements", is a collection of axioms, theorems and proofs about squares, circles acute angles, isosceles triangles, and other such things. Most of the theorems which are taught in high schools today can be found in Euclid's 2000 year old book. Euclidean Geometry was of great practical value to the ancient Greeks as they used it (and we still use it today) to design buildings and survey land. 1.2 Spherical Geometry: non-Euclidean Geometry is any geometry that is different from Euclidean Geometry. One of the most useful non-Euclidean geometries is Spherical Geometry which describes the surface of a sphere. Spherical Geometry is used by pilots and ship captains as they navigate around the world. Working in Spherical Geometry has some non intuitive results. For example, did you know that the shortest flying distance from Florida to the Philippine Islands is a path across Alaska? The Philippines are South of Florida - why is flying North to Alaska a short-cut? The answer is that Florida, Alaska, and the Philippines are collinear locations in Spherical Geometry (they lie on a "Great Circle"). Another odd property of Spherical Geometry is that

What is non-Euclidean geometry? Euclid's geometrical thesis, "The Elements" (c. 300 B.C.E), proposed five basic postulates of geometry. Of these postulates, all were considered self-evident except for the fifth postulate. The fifth postulate asserted that two lines are parallel (i.e. non-intersecting) if a third line can intersect both lines perpendicularly. Consequently, in a Euclidean geometry every point has one and only one line parallel to any given line. For centuries people questioned Euclid's fifth postulate. Even Euclid seemed suspicious of the fifth postulate because he avoided solving problems with it until his 29th example. Mathematicians stumbled with ways to prove the validity of the fifth postulate from the first four postulates, which we now call the postulates of absolute geometry. Those mathematicians who didn't fail were soon seen to have fallacious errors in their reasoning. These errors usually occurred because a mathematician had made self-fulfilling assumptions pertaining to parallel lines, rather than working with the other postulates. Essentially, they were forcing a result through the application of faulty logic. bodyOffer(29808) Though many mathematicians questioned Euclidean geometry, Euclidean thought prevailed through school mathematical programs. "The Elements" became the most widely purchased non-religious work in the world, and it still remains the most widely received of mathematical texts. Furthermore, mathematical inquiries into the nature of non-Euclidean geometries were often devalued as frivolous. The philosopher Immanuel Kant (1724-1804) called Euclid's geometry, "the inevitable necessity of thought." Such philosophical opinions impeded mathematical progress in the field of geometry. Karl Friedrich Gauss (1777-1855), who began studying non-Euclidean geometries at the age of 15, never published any of his non-Euclidean works because he knew the mathematical precedent was against him.

This is not the way in which Euclid originally defined his fifth postulate, but it is equivalent to his definition. In fact, geometers were troubled by the disparate complexity of the fifth postulate, and thought that it could perhaps be proved as a theorem from the other four. One attempt to prove that the fifth postulate was in fact a theorem was to assume its inverse, and derive a logical fallacy from it. This exercise did just the opposite of its goal: rather than prove that the fifth postulate was provable from the other four, it proved that you could assume either the fifth postulate or its inverse, and either assumption would produce a complete, self-consistent geometry. The fifth postulate produced the familiar Euclidean geometry. Its converse produced non-euclidean geometries.

Navigation Panel: (These buttons explained below Question Corner and Discussion Area Non-Euclidean Geometry Asked by Brent Potteiger on April 5, 1997 I have recently been studying Euclid (the "father" of geometry), and was amazed to find out about the existence of a non-Euclidean geometry. Being as curious as I am, I would like to know about non-Euclidean geometry. Thanks!!! All of Euclidean geometry can be deduced from just a few properties (called "axioms") of points and lines. With one exception (which I will describe below), these properties are all very basic and self-evident things like "for every pair of distinct points, there is exactly one line containing both of them". This approach doesn't require you to get into a philosophical definition of what a "point" or a "line" actually is. You could attach those labels to any concepts you like, and as long as those concepts satisfy the axioms, then all of the theorems of geometry are guaranteed to be true (because the theorems are deducible purely from the axioms without requiring any further knowledge of what "point" or "line" means). Although most of the axioms are extremely basic and self-evident, one is less so. It says (roughly) that if you draw two lines each at ninety degrees to a third line, then those two lines are parallel and never intersect. This statement, called

In particular, I would like to understand n -dimensional symmetrical `solids' (esp 4, 5 dimensions.) My son has recently been asking about a drawing of a `hypercube' (a 4-D cube) in an old book by George Gamov in which such an object was drawn and wants to understand how to extend the concept. I can't help! Can you help me to help him? Euclidean Geometry in higher dimensions is best understood in terms of coordinates and vectors. In fact, it is these which even give meaning to geometric concepts in higher dimensions. So, let me start with a quick overview of those (which you, as a physics graduate, will know anyway and may want to skip, but others reading the page may not): In 3 dimensions, we all have an intuitive understanding of what length and angle mean, and it is not at all clear how to extend these concepts to higher dimensions.
