symmetry in nature is an objective property, a major in modern science.It is a universal and general characteristics of our material world.
symmetry in nature - a concept that reflects the existing world order, and the balance of proportionality between elements of different systems or natural objects, balance the system, order, stability, then there is a certain element of harmony.
Symmetry and asymmetry - the opposite of the concept.The latter reflects the disorder of the system, lack of balance.
form of symmetry
Modern science defines a number of symmetries, reflecting the properties of the individual hierarchy levels of the organization of the material world.Various types of symmetry or shape:
- space-time;
- calibration;
- isotope;
- mirror;
- commute.
All of these types of symmetries can be divided into external and internal.
External symmetry in nature (spatial or geometric) is represented by a huge diversity.This relates to crystals, living organisms, molecules.
internal symmetry is hidden from our eyes.It manifests itself in laws and mathematical equations.For example, Maxwell's equation, which determines the relationship of magnetic and electrical phenomena, or a property of gravitation Einstein linking space, time and gravity.
What is symmetry in life?
symmetry in living organisms has been formed in the course of evolution.The earliest organisms that originated in the ocean, have a perfect spherical shape.In order to infiltrate a different environment, they had to adapt to new conditions.
One way this adaptation is a symmetry in nature at the level of physical fitness.Symmetrical arrangement of parts of the body is provided with the balance of movement, vitality and adaptation.The outer form of man and large animals have a fairly balanced view.In the vegetable world, too, there is symmetry.For example, tapered crown spruce has a symmetrical axis.This vertical shaft, for the stability of the thickened bottom.Symmetrically in relation to it is a separate branch, and the shape of the cone allows the efficient use of crown luminous flux of solar energy.External symmetry of the animals helps them maintain balance while moving, enriched with energy from the environment by using it rationally.
The chemical and physical systems, the symmetry is present, too.Thus, the most stable are molecules that have high symmetry.Crystals - is a high-symmetry of the body, their structure periodically repeated three measurements of elemental atoms.
Asymmetry
Sometimes the internal layout of the in vivo is asymmetric.For example, the heart is the person on the left, the liver - right.
plants during the life of the soil to absorb mineral compounds from chemical molecules symmetrical shape and your body converts them into asymmetric substances: protein, starch, glucose.
asymmetry and symmetry in nature - they are two opposite characteristics.These are the categories that are always in the fight and unity.Different levels of development of matter can wear properties of the symmetry, asymmetry.
Assuming that equilibrium is a state of calm and symmetry, and the movement and disequilibrium caused by the asymmetry, we can say that the concept of equilibrium in biology is no less important than in physics.The biological form of motion is characterized by the principle of stability of thermodynamic equilibrium of biological systems.This asymmetry, which is a stable dynamic equilibrium can be considered a key principle for solving the problem of origin of life.
