The crane is auspicious in Japanese culture; legend says that anyone who folds one thousand paper cranes will have their heart's desire come true. Many Japanese prepare a garland of one thousand paper cranes senbazuru when a friend or family member is ill, as a form of prayer for their recovery.
A famous story has turned the origami crane into a symbol of peace. In , a twelve-year-old Japanese girl named Sadako Sasaki, who had been exposed to the radiation of the atomic bombing of Hiroshima as an infant, was dying of leukemia. She decided to fold one thousand cranes in hopes of becoming cured.
When she realized that she would not survive, she wished instead for world peace and an end to suffering. Sadako folded more than 1, cranes before her death and was buried with a wreath of one thousand cranes to honor her dream.
While her effort could not extend her life, it moved her friends to make a granite statue of Sadako in the Hiroshima Peace Park: a young girl standing with her hand outstretched, a paper crane flying from her fingertips.
The tale of Sadako has been dramatized in many books and movies. In one version, Sadako wrote a haiku that translates into English as: "I shall write peace upon your wings, and you shall fly around the world so that children will no longer have to die this way. This technique allows for a more rounded sculpting of the model, which becomes rigid and sturdy when dry. An example of a paper art star on a window, which does not meet the typical requirements of origami as it is constructed from multiple pieces of paper Special origami paper, often also referred to as kami, is sold in prepackaged squares of various sizes ranging from 2.
It is commonly colored on one side and white on the other; however, dual colored and patterned versions exist and can be used effectively for multi-colored models.
Origami paper weighs slightly less than copy paper, making it suitable for a wider range of models.
Foil-backed paper, just as its name implies, is a sheet of thin foil glued to a sheet of thin paper. Related to this is tissue foil, which can be made by gluing a thin piece of tissue to kitchen aluminum foil. Foil-backed paper is available commercially. Both types of foil materials are suitable for complex models. Artisan papers such as unryu, lokta, hanji, gampi, kozo, and saa have long fibers and are often extremely strong.
As these papers are floppy, they are often backcoated or resized with methylcellulose or wheat paste to stiffen them before folding.
These papers are extremely thin and compressible, allowing for thin, narrowed limbs as in the case of insect models. Mathematics of Origami The practice and study of origami encapsulates several subjects of mathematical interest.
For instance, the problem of flat-foldability whether a crease pattern can be folded into a two-dimensional model has been a topic of considerable mathematical study. Paper exhibits zero Gaussian curvature at all points on its surface, and only folds naturally along lines of zero curvature.
But the curvature along the surface of a non-folded crease in the paper, as is easily done with wet paper or a fingernail, no longer exhibits this constraint.
The problem of rigid origami "if we replaced the paper with sheet metal and had hinges in place of the crease lines, could we still fold the model? For example, the Miura map fold is a rigid fold that has been used to deploy large solar panel arrays for space satellites. Technical Origami Origami Chinese dragon The field of technical origami, also known as origami sekkei, has developed almost hand-in-hand with mathematical origami.
In the early days of origami, development of new designs was largely a mix of trial-and-error, luck and serendipity. With advances in origami mathematics however, the basic structure of a new origami model can be theoretically plotted out on paper before any actual folding occurs. This method of origami design was pioneered by Robert J. Lang, Meguro Toshiyuki and others, and allows for the creation of extremely complex multi-limbed models such as many-legged centipedes and human figures with fingers and toes.
The main starting point for such technical designs is the crease pattern often abbreviated as 'CP' , which is essentially the layout of the creases required to form the final model. Although not intended as a substitute for instructional diagrams, folding from crease patterns is becoming popular, partly because of the challenge of being able to 'crack' the pattern, and also partly because the crease pattern is often the only resource available to fold a given model, should the designer choose not to produce diagrams.
Paradoxically, when origami designers come up with a crease pattern for a new design, the majority of the smaller creases are relatively unimportant and added only towards the completion of the crease pattern. What is more important is the allocation of regions of the paper and how these are mapped to the structure of the object being designed. Once this figure is computed, the creases which are then used to obtain the base structure can be added.
This is not a unique mathematical process, hence it is possible for two designs to have the same circle-packing, and yet different crease pattern structures. Origami as a Hobby Origami is a popular hobby in Japan for both children and adults. Before the advent of television and video games, origami was a common form of indoor entertainment for Japanese children. Stationery shops carry many varieties of origami paper.
In addition to traditional papers, new designs are frequently released, printed with popular cartoon characters, exciting patterns and colors, and thermal inks which change color according to the temperature. Some origami designs produce toys such as paper samurai helmets, balls, boxes, water bombs, hopping frogs, ninja stars, paper airplanes and animated faces. Origami is used for a number of ceremonial and religious purposes, such as the ornamentation of temples and ancestral shrines, presentation of gifts and temple offerings, preparations for New Year celebrations, and the decoration of plaques commemorating special occasions.
Origami is sometimes used as a means of practicing Zen Buddhism , with special attention to ritual, concentration, the internal attitude of the artist, and the meaning of the designs. Origami and Child Development Paper folding is recognized as an excellent means of developing hand-eye coordination and mental concentration in young children.
