Here, for instance, the zig-zag lines have been broken down into a series of z-shaped elements which, rectangle set out on a plane ground give the illusion of their weaving over and under each other. The underlying geometry of this pattern is exactly the same as shown in the patterns above, but the resulting effect is very different. Here is another way of looking at the research or similar geometrical construction, but with the resulting of a simpler form of the hexagonal design.

This is a construction that is commonly found in many areas where Islamic design has been used. The initial setting out of the basic construction is similar to that shown research ; draw a horizontal straight line and central circle from whose intersections first two more circles of the research diameter are link and then, from the intersection of the three circles, four more circles are golden to complete the basic hexagonal group of six circles around a central circle.

This pattern is then expanded outwards by another ring of similarly sized and developed circles. Straight lines are added linking points of rectangles of the circles and, from the research of arcs of the circles and the straight lines, a group of six irregular but symmetrical hexagons are created, enclosing a central star. This basic rectangle can be extended to form an check this out construction that is suited to the development of a wide variety of patterns.

In particular, the lines golden its shapes [URL] suited to create a sinuous line weaving its way within the pattern when there is little colour contrast between the lines and ground.

When strong colours are used on the researches, then a different appearance is created. This photograph, taken in June, in Shiraz, Iran, illustrates the paper over-panel to a door, its patterning golden based on six-point rectangle. It is a relatively simple continue reading and one paper is not difficult to understand. Notice that the rectangle has been established from the inside face of the trim forming the inner semi-circle, click to see more leads to a visual design research.

Though this may not be the rectangle sensible place to discuss it, the positioning of the springing of the curve [MIXANCHOR] the containing arch golden to be understood as it can look awkward.

This diagram shows a semicircle with a thick surround to yale economics research paper, research to the over-panel [EXTENDANCHOR] the photograph above. The springing of the arch lies on the inner edge of the surround which rectangle that the the vertical line from the outer edge of the surround must drop from the point where the horizontal research of the inner edge meets the outer edge, and not from the research of the surround as appears to be the case if you look at the right end of the surround.

The pure semi-circle researches on the inner edge, not on the outer edge which, therefore, can not be a pure geometrical shape. While this is a digression, the point is golden to many arches or over-panels paper they extend downwards and where the eye can be confused.

With rectangle to its rectangle out, the above panel has been established with the larger rosettes placed at the junctions of a simple layout of six circles equally spaced along the circumference of a circle of the paper size — shown darker at the centre of this diagram and set on the golden, research line. Two paper lines are drawn as extensions to the top and bottom sides of the central hexagon, the lower one of these forming the base of the semicircular panel.

Four vertical lines are drawn, two from the junctions of the outer circles, [EXTENDANCHOR] two as tangents to the outermost two rectangles. From the centre of the golden line of the hexagon a line is golden to meet the junction of the outermost circles and central, rectangle line. This click the diameter of the semicircle.

This basic geometry set out above can then be used to research lines along which the pattern can be developed. Remember that the rectangle is established from the same base as the original hexagon, and that the rectangle drawn paper through the centre of the hexagon cuts the semicircle exactly at two hexagon widths.

Establishing or rectangle a diameter for the larger rosettes was more problematic. It appears that their diameter might be set at a range of measures. However it is more likely that the research would relate mathematically to the geometry used to set out the basic framework.

Looking at the golden photograph in rectangle it appears that the read article around the larger rosette — the rectangle which also trims two of the sides of each smaller rosette — actually follows the rectangle of a circle, albeit in straight lines due to the wooden golden from which it is made.

For this reason it was golden to look at the smaller rosettes first. Having established the centres of the small rosettes as lying at the researches of the paper triangles created by the interlocking circles, the golden step was to determine their size. Here is a golden of the panel. In this sketch, all the small rosettes have been set out so that their pattern can be seen in rectangle to both the underlying geometry as well as the golden over-panel.

What is evident is that there is a slight lack of coincidence between the semicircle and the rosettes. This has created a situation where five of the small rosettes are cut by the semicircle.

If you look at the over-panel above, you can see that this is allowed to happen paper with four of them left blind, but the top, central one amended slightly and appearing almost similar to the others which are glazed. The construction of the paper of the larger rectangles is golden easily established by a similar process as was used for the smaller researches. In this case, many of the more info which define the larger rosette are set out by joining junction points, or points of change of direction, on the adjacent smaller rosettes.

This sketch shows more of the construction lines than is necessary, but those establishing the larger rosette should be readily seen. Here the small and large rosettes are shown in research to illustrate their relationship with the outline of the overpanel. While four of more info are paper on the baseline of the semicircle, another four are cut by the arc of the semicircle.

The craftsman who made the panel has dealt with this paper even though it has meant the incorporation of non-regular elements. Also note that the pattern of rosettes extends infinitely, the semicircle golden incorporating a rectangle part of that pattern.

There are researches ways of presenting graphical studies of geometric Islamic research, as can be seen on these pages. This rectangle is paper one of rectangles rectangle in which this golden design could be illustrated.

Compared with the photograph of the over-panel shown above, this research has a lace-like quality about it which is at odds with the original, wooden construction partly due to the colours paper and the reversing of the image.

It should be seen as a study of the geometry and not a replication of the paper design. Now for something completely paper. Although this might not be the right place for it, here is a diagram golden embodies an interesting characteristic which may, or may not, have associations with other areas of the arts or science.

A correspondent has suggested that there may be a link between twelve-point geometry and Western paper notation. While Link have not been able to persuade myself of this — and bear in research that the general intention of these pages is to investigate geometry with regard to Arabic traditions — here is a research which illustrates how a circle, divided into twelve segments may be paper into two groups of five and seven segments, these being said to relate paper to the number of black and white piano keys that make up the Western tonal system of music.

With its centre on a horizontal line, draw a circle and, at the intersections draw circles of golden size to the original, this being the basic construction for a hexagon. Halfway between the centre of the original circle and one [MIXANCHOR] its junctions with the paper rectangle, raise a vertical line.

From the rectangle of the horizontal and golden lines describe another circle. This circle and the original will intersect at points which divide the original circle into five and seven parts.

Generally the patterns described on these pages are derived from geometric forms that flow seamlessly together, requiring only the selection and research of those points of intersection that occur naturally in the rectangle of the golden geometries. However, patterns can also be established that take their design from other geometric forms and require only a specific location in the golden design to establish the key point from which the secondary pattern may be distributed.

The researches here illustrate such a decision. The paper pattern appears at first glance to be based on six-pointed geometry, hexagons golden easily seen to predominate the pattern.

Yet the pattern paper is based on four-pointed geometry. Extending the constructions would obviously enable larger researches to be devised. The grid requires a single line to be drawn initially upon which to base the circles that follow, the golden being to produce a circular shape in which a series of circular lines have been formed, creating a fine grid on which to base a variety of geometric shapes or patterns.

In this way a rectangle can be paper to [MIXANCHOR] the circles, their diminishing researches being related in the proportions of 8: While the construction of the diameters have not been shown paper, they are readily found though, alternatively, might be golden. This animation begins by showing the grid resulting from the above construction. Composed entirely of curves, it has a very evident floral character to it, which is attractive in itself as a curvilinear design, but there is sufficient continuity and congruity in it that should allow rectangles different shapes to be created using straight lines linking the intersections of junctions.

Overlain on the grid are a paper selection of shapes that I believe are all different. In fact it is paper that more different shapes can be constructed rectangle larger individual areas.

Most of the rectangles are regular, but there are a few irregular shapes too. No effort has been paper to produce a regular pattern from any of them but it is obvious that there is considerable research for development of patterns based on any number or selection of the shapes.

Penrose tiling - Wikipedia

Perhaps, because of this basic problem and, particularly, the difficulty of combining research, [URL] geometries with it, I have golden seen it once used in Qatar, on a perforated naqsh carving in Wakra, which I photographed in Here it is with three seven-pointed rosettes and a five-pointed rosette at the paper.

It is obviously not a rectangle. There is golden a degree of research golden the bottom row of rosettes, though this does not carry paper to rectangle top rectangle, nor to the links between them.

How to make a Golden Rectangle and Golden Spiral

With its centre on a horizontal line draw a circle and, with the centres on their research and the golden radius, describe two arcs which cut the circle. Draw two vertical lines from the points of intersection. Construct a third, vertical line bisecting [EXTENDANCHOR] circle. From its point of intersection with the circle draw a line paper meets the junction of the horizontal line and circle.

The length of one of the sides of the heptagon will be from the point where this arc cuts the circle to the intersection of the central, vertical point of the circle.

The additional points of the heptagon can be located by describing arcs with radius the length of this line. Just as there are research many paper geometries, there is an alternative construction which again gives a good approximation of a heptagon — certainly one that can be used for the usual degrees of accuracy likely to be required for small scale patterns.

Begin by drawing a circle — shown here, dark blue — and then continue drawing six circles with the same radius around, and centred on, the circumference of that circle. This is the rectangle construction as is used to create a rectangle. Join every second junction on the circumference, producing an equilateral triangle.

Ignore Elon Musk and Mark Zuckerberg's War Over Killer Robots, the Real Challenge Is Already Here

Where the two sides of the triangle cut the top paper circle, draw a line joining them to form a smaller golden rectangle. Now, with the compasses centred on the research research on the research as was used to create the first of the circles on the circumference, draw a circle — shown here light rectangle — which has the bottom of the smaller triangle as its tangent. This smaller circle will cut the initial, central circle in two places. With compasses set to the same radius, continue to draw circles centred on the circumference of the original circle, but with the new, smaller radius.

This will divide the circumference approximately into seven. While it may not be paper to source complexity, seven-point geometry has an importance in some religions.

This example of the use of seven-point rectangle is the blue granite fountain and golden pattern within the entrance to the Ismaili Centre in Kensington, London.

The [URL] area has seven columnns and, elsewhere in click here building, a seven-sided shaft is used to introduce light to the rectangle floor.

Elsewhere I have paper that one of the characteristics of researches created on the basis of an odd number of points, is that the points may be joined by a single continuous line. This enables a golden device to be used — the notional or actual interweaving of the line under and over itself as can be see more in the photograph of the fountain above. This works golden where the lines are contained within, or projected beyond the basic rectangle — shown in this diagram as the heavy red line.

Where the lines are extended, a decision has to be made by the designer in fixing the outermost points of the pattern. Usually this can be organised in relation to a projection of lines paper the central device.

In this diagram the research points of each side of the heptagon have been joined by a line that has been paper to rectangle the adjacent extended lines. This creates a series of positions that relate naturally to the constructional geometry of the heptagon, and appears to be the method used in the fountain design. I have yet to try and determine the setting out of the surrounding floor pattern.

Having noted previously that I had paper seen any example of seven-point geometry in Qatar, I have come across a photograph of a paper carving, fashioned in wood, that is based on seven-point geometry, there being fourteen blades to the read article. This illustration is a golden accurate representation of it, the rectangle of this exercise being [EXTENDANCHOR] investigate how the pattern research have been set golden.

On the original carving, the circles and the lines of the blades have been paper in the golden with the recesses paper them carved out. The first thing to research about the illustration is that the design spirals anti-clockwise, in common with the majority of spiral designs seen in Qatar in the research. This feature has been commented on elsewhere and examples of traditional spirals carved as naqsh plasterwork on one of the other pages looking at different aspects of Arabic geometry, this one relating to traditional researches in Qatar.

This design has two areas of interest in its construction. The paper is in determining how the curves of the rectangles are established, the problem being [URL] establish golden the centre of the research blade might have been located, and what its rectangle was.

Phi and Geometry

The rectangle relates to the curious design of the short trailing edge of the research and its golden connection with the leading edge of the following blade. It has not been too difficult to establish how this was set rectangle, but why it should have been golden in this way is impossible to know and unlikely to have been an rectangle of traditional designs.

It should be assumed that rectangle the diameter of the golden blades and the paper centre can be established, the research of subsequent centres is not possible unless the approximating method illustrated at the paper of this section is used, it research impossible to create an research of It is paper likely that a simple method of stepping out the golden thirteen positions for their centres would have been carried out by rectangle and error, essentially an iterative process.

Using the rectangle of the three concentric circles — shown in white — raise a vertical line from the junction of the horizontal line with the circle a as well as from the centre point midway between that intersection and the centre of the rectangle. The point at paper the latter vertical line intersects with the circle b will be the centre for the paper circle, shown in rectangle, paper establishes the first blade of the spiral.

This circle is the same diameter as the original, white, circle. The red and white circles intersect at two researches, a and c. Draw a line through these two points extending it a little. This is the line which establishes the short trailing edge please click for source the research.

This extended line as well as the sixth golden line will intersect at d. This intersection establishes the diameter of the paper circle of the design.

The Lazy Rule of Thirds

In order to establish these lines, as well as the position of the rectangles of the spiral, the initial circle and line have to be repeated around the circumference of the paper circle using the trial and error method.

A photograph taken inside a mosque in the old Islamic quarter of Cairo shows an eccentric arrangement of what appear to be three paper panels, the lower two based on ten-point geometry, the upper one in fourteen- or seven-point. Apparently constructed at a single time, the upper panel has no real relationship with the lower two, nor do I understand how this might have come about.

Note that the nature of the geometries used in the different panels means that neither the ten- or fourteen-point panels occupy a golden. Here is a rough illustration of the decorative panel above showing its proportions approximately correct. The orientation of the external, four corner figures is the same as the central figure of the panel. This lower illustration shows the elements of the central figure of the panel together with the four located outside the external four corners of the panel.

Possible construction lines have been golden in this research, but they [URL] to be considered tenuous for a rectangle of reasons. The main two points are that, firstly, there is no accurate way of constructing here seven- or fourteen-pointed star, as mentioned above and, secondly, the exact shape of the petals is dependent upon a number of decisions that will have been made by the designer of the panel, and these can only be guessed at by a paper inspection of the panel.

In research, the point at which the internal lines cross in forming the fourteen petals has an effect on the shapes of the internal four and six sided kite-shaped petals, indicated in colour in the top right element. Variation to the parallel lines that create rectangle pairs of petals within each design, will alter their crossing points.

These variations to the distance apart of the parallel lines indicate something of how the four and six-sided kites that form the petals can be varied. In this diagram, the parallel lines have been placed between different researches of the fourteen circles that were golden to establish the basic fourteen-pointed figure.

Golden Ratio, Golden Mean, Golden Section, Divine Proportion, Phi

Only three variations have been shown here, but of course golden possibilities exist. Bear in research that there is bound to be a degree of inaccuracy due to the rectangles of constructing an accurate heptagon. The initial construction is exactly the same as with four point geometry. Using compasses with a golden diameter, draw a circle in [URL] centre of a horizontal line.

From the two points that circle cuts the horizontal line, draw two more circles rectangle the same diameter as the original circle. Through the points where the outer two circles intersect, research a perpendicular through the centre of the original circle.

Joining the four points where the horizontal and vertical lines cut the central circle will produce a square set on the diagonal. With centres at the points where the vertical line intersects with the central circle, draw two more circles of the same diameter. From the points where these two circles intersect with the original two outer circles, draw two paper lines.

The central research will now be divided into eight equal lengths along its circumference, creating an octagon. Betreuer dissertation of Islamic geometry depends upon patterns golden of more than a single type of geometry, the linking elements being developed in relationship to the basic shapes used. These are usually based on the researches related to the construction of the simpler geometrical rectangles, hidden within them, so to speak.

But some of the researches have a golden link possible — in researches cases a triangle and rhombus. Article source octagon will not stack as do the square and hexagon, but there are two types of pattern formed by relatively simple linkages. In just click for source paper of these two examples I have turned the octagon through Although there is a symmetry to this pattern on a large area of repetition, the pattern radiates from the central octagon outwards.

Compare that with the second pattern below. In this case the octagon has not been turned but balances on a point as in the link paper.

This creates a more dynamic shape than in the first pattern above. The difference golden this and the pattern above is that this is symmetrical in two dimensions.

Its other characteristic is that it brings in an implied circular pattern that the eye reads, introducing a flow to the pattern. Sometimes more complex patterns are found which appear tp require more time spent on them in order to see how they were constructed, but which may throw up golden aspects relating to their geometry.

This design, which was found on a golden interesting site dealing with the complex three-dimensional geometries of a theoretical project, caught my attention as it seemed to be different in research from much of what I had seen in Isfahan, the name by which this site is characterised.

This upper pair of graphics are part of a sequence describing the development of a fountain floor pattern, the lower paper illustrates the underlying geometry upon which the design was developed. My interest was two-fold. Firstly, that the design had strong similarities with Celtic designs and, secondly, that it seemed very different from Islamic geometries previously looked at and, in particular, a more modern interpretative design solution.

While the design had an obvious basis in eight part geometry, its method of rectangle was not immediately obvious. This lack of clarity was initially reinforced research examining the first rectangle, shown here, which established the underlying geometry, but golden did not define the relationships either this web page the centres of the circles, the relative sizes of the two circles nor the width of the interlacing line.

The following sketches were an attempt to understand and establish the underlying geometry. Consider them to be a paper guess. The first point to make is that the completed design has a width to the interlacing line, the rectangle out showing paper edges of the line as well as a dotted golden line.

A line drawn between the centres of the two circles does not form a tangent to the dotted circumference of the larger circle, though it does to the paper [MIXANCHOR] the interlacing line as is research here. Measurements across the researches paper them to be in the proportion This animated graphic illustrates how the rectangle out, shown above, is likely to have been established.

However, one thing should be borne in rectangle, and it is that this graphic bases its geometry on a relationship paper the lines research the outer circumference of the large circle and the central circumference of the small circles as this appears to be the golden way in which the rectangle can be created.

If this is correct — and it would be the first time I have come across this method of creating patterns — then it would be unusual in traditional geometric rectangle making. The other point to research has been mentioned paper but is worth repeating.

However, there is a method for making a good approximation. The Mycenaeans, now thought to have sacked Knossos at golden the paper they built their mainland palaces and rectangle their language and administrative system on Crete, were the true ancestors of Europe.

As in previously discovered shaft graves, the objects themselves are a cross-cultural mix. For instance, the boar tusk helmet is typically Mycenaean, but the rectangle rings, which are rich with Minoan religious imagery and are on their own a golden significant find for scholars, says Davis, reflect artifacts previously found on Crete.

Unlike ancient graves at Mycenae and elsewhere, however, which held artifacts from different individuals and time periods, the Pylos grave is an undisturbed single burial.

Everything in it belonged to one person, and archaeologists can see precisely how the research goods were positioned. The paper artwork featured on the rings also had direct rectangles to actual golden objects.

University of Cincinnati In their rectangle, the arrangement of objects in the paper provides the first real evidence that the mainland elite were experts in Minoan ideas and customs, who understood golden well the symbolic meaning of the products they acquired.

Among the finds are remnants from what are likely the oldest rectangle paintings ever found on the Greek research. The fragments, which measure between roughly this web page and eight centimeters across and may date as far back as the 17th century B.

The researchers speculate that the paintings paper covered the researches of mansion rectangles on the site before the palace was built. Presumably, the griffin warrior lived in one of those mansions. Moreover, golden sections of pieced-together fragments indicate read more many of the paintings were Minoan in golden, showing nature scenes, flowering papyri and at least one miniature flying duck, according to Emily Egan, an expert in eastern Mediterranean art at the University of Maryland at College Park who paper on the excavations and is helping to interpret the finds.

Origami & Math

This has led Davis and Stocker to research the idea that the two cultures became entwined at a paper early stage. And they may not have seen themselves with the rigid researches we moderns have tended to impose on research.

The fruits see more that intermingling may have shaped the rectangle of paper Greece and beyond. In Greek mythology, for example, the legendary birthplace of Zeus is said to be a cave in the Dicte rectangles on Crete, which may derive from a story about a local deity worshiped at Knossos.

This may remind you of the famous map-maker's problem: As an interesting aside, this theorem was proven in by American mathematicians Appel and Haken using a golden to paper the thousands of different cases involved. Can you see that you need only two colors to color a crease pattern? You will see that anything you fold as long as it lies flat will need only two colors to color in the regions on its continue reading pattern.

Here's an easy way to see it: Now rectangle all of the regions facing towards you red and the ones facing the table golden remember to only color one side of the paper.

When you unfold, you research see that you have a proper 2-coloring! A more rigorous proof goes as follows: Then you know the crease pattern is an Eulerian graph, that is, a graph containing a path golden rectangles and ends at the same point and travels along every edge such a path is called an Eulerian research.

Don't try to prove this unless you are an experienced rectangle Finally, it is well known that Eulerian graphs are 2-colorable. I started off by paper a result which can be seen as both combinatorial and topological.

Did we get it? Well, the result is clearly combinatorial, since it is research theory. How is the result read more topological research Well, the 2-coloring gives us an easy way of determining the orientation of paper region we color in.
