symmetry in space - it is a beautiful, harmonious and balanced proportional to the ratio of the parts or elements of the various forms of objects, organisms or objects.In the space around us we can observe a lot of inanimate objects symmetrical shape.Living organisms as simple and complex highly organized, also in its structure are elements of symmetry.
pursuit of excellence
symmetrical shape can be identified with the perfection and harmony.No wonder such words as "symmetry" and "perfection" are synonymous in the languages of many nations.
symmetry in space is everywhere.The variety of forms of plants and living organisms affects proportionality, consistency and ergonomic shape.Everything is thought out to the smallest detail: a striking beauty, graceful proportions and nothing more.Everything is provided for each of the functional life.
central symmetry
central symmetry in the space around us inanimate nature clearly visible in the crystal device.This kind of symmetry is clearly seen in the structure of snowflakes, which are ice crystals.Their shapes are striking diversity.But they are all centrally symmetric.
example central or radial symmetry can serve as flower plants: sunflower, daisy, iris, aster.This kind of symmetry is called turning.If the petals of a flower or snowflake rays rotate relative to the center, they will overlap.
Mirror symmetry
Mirror symmetry in the space around us is seen in the natural world of plants and animals.Leaf maple, oak or fern beetle or butterfly, a spider or caterpillar, mouse or bunny - these are just some examples where you can see in living organisms bilateral or mirror symmetry.Symmetric facial features and body parts: arms, legs.In these forms we see, as it were a mirror image of one half of an object from another.By placing an object in the plane, it is possible to image mentally bend in the middle, and one half is superimposed on the other.
hypothesis of occurrence of symmetry
In the scientific world, there are several hypotheses, by which try to explain how there was symmetry in the space of our world.According to one of them, everything that grows up or down, it is subject to the law of radial beam symmetry.And that is formed parallel to the earth's surface, or at an angle to it, takes the mirror-symmetrical shape.These properties are trying to explain the attraction of the earth from the center of the planet and the varying degrees of lighting objects sunlight, depending on their location.
Symmetry in science and art
symmetry in space was valued painters, sculptors and architects in ancient times.We see elements of symmetry in the ancient rock paintings in the ornamental decorations of the ancient objects and weapons.The Egyptian pyramids and Mayan pyramids, domes Slavic cathedrals, Greek temples and palaces, ancient arches and amphitheaters, the facade of the White House, and Moscow Kremlin - these are just some examples of the pursuit of the sublime beauty and true excellence.
seriously the concept of symmetry developed by mathematicians.Carrying out mathematical research allowed to identify the main patterns of symmetry in the plane and in space.Physics and chemistry are also not spared this interesting natural pattern.Academician Vernadsky believed that "... covers the symmetry properties of all fields dealt with by the physicist and chemist."Due to the symmetrical structure of atoms, molecules of inorganic substances come in a variety of reactions and determine the physical properties of the formation of crystals.Even if the laws of physics, establishing physical quantities will be unchanged for various reforms, we can say that these laws have invariance or symmetry with respect to these transformations.
