EGYPTIAN GEOMETRY DETERMINING THE VALUE OF THE PYTHAGOREAN THEOREM Sacred Geometry? THIS PAGE IS UNDER CONSTRUCTION Unfortunately, a great many school children are misslead into believing as 3+1/8 using the observation below that the area of a circle of radius is "close to" the area of a square 8 units on a side. Until recently, Archimedes of Syracuse (250 BC) was generally consider the first person to calculate pi to some accuracy; however, as we shall see below the Egyptians already knew Archimedes (250B.C.) value of = 256/81 = 3 + 1/9 + 1/27 + 1/81, (the suggestion that the egyptians used = 3.1415 for <3+1/7 while in China in the fifth century, Tsu Chung-Chih calculate pi correctly to seven digits. Today, we "only" know to 50 billion decimal places Note 1 khet is 100 cubits, and 1 meter is about 2 cubits. A setat is a measurement of area equal to what we would call a square khet. An alternate conjecture exhibiting the value of is that the egyptians easily observed that the area of a square 8 units on a side can be reformed to nearly yield a circle of diameter 9. Rhind papyrus Problem 50 . A circular field has diameter 9 khet. What is its area. The written solution says, subtract 1/9 of of the diameter which leaves 8 khet. The area is 8 multiplied by 8, or 64 setat. Now it would seem something is missing unless we make use of modern data: The area of a circle of diameter

The Geometry Applet version 2.2 *** If you can read this, you're only seeing an image, not the real java applet! *** I began writing this applet in Feb. 1996. The current verion is 2.2 which fixes a couple of bugs in 2.0 and has a new construction to find harmonic conjugate points. Version 2.0 (May, 1997) does three-dimensional constructions whereas the earlier version 1.3 only did plane constructions. Version 2.0 also has many minor improvements. It takes a while to test everything. Please send a note if you find any bugs. They'll be fixed as soon as possible. (Note that arcs and sectors on slanted planes cannot yet be illustrated.) Also, there may be still later versions than 2.2 with more functionality. This geometry applet is being used to illustrate Euclid's Elements . Above you see an icosahedron, that is, a regular 20-sided solid, constructed according to Euclid's construction in proposition XIII.16 Another example using this Geometry Applet illustrates the Euler line of a triangle Here's how you can manipulate the figure that appears above. If you click on a point in the figure, you can usually move it in some way. A free point , usually colored red, can be freely dragged about, and as they move, the rest of the diagram (except the other free points) will adjust appropriately. A sliding point

About Saltire Geometry Java Applet Gallery Saltire's Geometry Gallery is a collection of Java applets showing interesting geometry configurations. All applets are dynamic in that user input can cause the configuration to change. In some cases, points can be dragged. In other cases dimensions can be changed via edit controls. Some of the applets feature animation. Basic Geometry Applets in this gallery exhibit basic geometrical properties of angles in parallel lines and circular configurations. We also look at pythagorean triples and incircles. Triangle Calculators Four triangle calculators are presented, which allow for the triangle to be specified either by three sides, two sides and the included angle, two sides and the non-included angle or two angles and one side. In all cases the remaining sides and angles are computed. Advanced Geometry A number of advanced geometrical configurations are presented. These cover theorems about common tangents to circles, Napoleon's theorem on the incenters of equilateral triangles and a number of textbook problems as well as an illustration of Casteljeau's spline construction algorithm.

Geometry From Wikibooks, the open-content textbooks collection Jump to: navigation search The word geometry originally comes from Greek ( geo meaning world, metri meaning measure) and means, literally, to measure the earth. It is an ancient branch of mathematics, but its modern meaning depends largely on context. It was one of the two fields of pre-modern mathematics, the other being the study of numbers. In modern times, geometric concepts have been generalized to a high level of abstraction and complexity, and have been subjected to the methods of calculus and abstract algebra, so that many modern branches of the field are barely recognizable as the descendants of early geometry.

By using this site, you expressly agree to be bound by the Privacy and Security Policy abstract expressionism abstraction artist's books ... Douglas Wheeler Beyond Geometry examines a group of related artistic developments involving the use of radically simplified form and systematic strategies, which emerged in Europe and the Americas between 1945 and 1979. New and influential modes of abstraction emerged following World War II. Most artists represented in Beyond Geometry sought a new, more active relationship with the spectator. Since the early twentieth century, artists, like scientists and philosophers, have explored notions of relativity, which propose a constantly changing world defined by dynamic forces and relationships. Following World War II, traditional composition seemed to many to be concerned more with style than with substance, a superficial way of making a work look good that had little to do with its meaning. Beginning in the mid-1960s, in an attempt to make their creative process accessible, certain artists made the intellectual aspects of artistic production and reception the subject of their work. Beyond Geometry examines a group of related artistic developments involving the use of radically simplified form and systematic strategies, which emerged in Europe and the Americas between 1945 and 1979. This period saw the advent of the Cold War and the war in Vietnam; the civil rights movement and the women's movement; and the questioning of family values, sexual orientation, and racial stereotyping. In the art world, dominance shifted from Europe to the United States. Coming after the height of modernism and before the first fully postmodern generation, the period includes what was arguably the most influential epoch for art since

Sacred Geometry Sacred geometry is geometry that is sacred to the observer or discoverer. This meaning is sometimes described as being the language of the God of the religion of the people who discovered or used it. Sacred geometry can be described as attributing a religious or cultural value to the graphical representation of the mathematical relationships and the design of the man-made objects that symbolize or represent these mathematical relationships. The golden ratio was often used in the design of Greek and Roman architecture. A contemporary usage of the term describes a supposed re-discovered mathematical order to the intrinsic nature of the Universe that is represented in crop circles and in ancient architecture such as the Great Pyramid and Stonehenge. Wikipedia Fibonacci Number The Golden Ratio - Phi - Spiraling Consciousness Blocks - Grids The golden ratio, also known as the god ratio, golden proportion, golden mean, golden section, golden number, divine proportion or sectio divina, is an irrational number, approximately 1.618 033 988 749 894 848, that possesses many interesting properties. Shapes proportioned according to the golden ratio have long been considered aesthetically pleasing in Western cultures, and the golden ratio is still used frequently in art and design, suggesting a natural balance between symmetry and asymmetry. The ancient Pythagoreans, who defined numbers as expressions of ratios (and not as units as is common today), believed that reality is numerical and that the golden ratio expressed an underlying truth about existence.

Projective geometry is a beautiful subject which has some remarkable applications beyond those in standard textbooks. These were pointed to by Rudolf Steiner who sought an exact way of working scientifically with aspects of reality which cannot be described in terms of ordinary physical measurements. His colleague George Adams worked out much of this and pointed the way to some remarkable research done by Lawrence Edwards in recent years. Steiner's spiritual research showed that there is another kind of space in which more subtle aspects of reality such as life processes take place. Adams took his descriptions of how this space is experienced and found a way of specifying it geometrically, which is dealt with in the Counter Space Page A brief introduction to the basics of the subject is given in the Basics Page See also Britannica: projective geometry The work of Lawrence Edwards is introduced in the Path Curves Page , and some explorations of his work on further aspects is described in the Pivot Transforms Page . This is mostly pictorial, with reference to documentation.
