People who see the sci-fi movie "fifth element" should also remember four basic elements of Plato (PLATO): fire, water, gas, soil. In fact, the fifth element, Plato believes is the mystery of the universe - ether. (Excellence: Berla Tu's thoughts have a great impact on the development of Western science, and are widely respected, so we can now understand why it is widely accepted by Western scientists in the universe, even when light speed is in the universe The fact that the constant energy is not reduced in medium speed is discovered, and some scientists seek new explanations on light in the Toozing spread).
The five elements of Plato correspond to the only five positive and polyhedrals in the three-dimensional world - the four sides, the octahedron, the square (six sides), the two sides, and the 20th side.
Positive tetrahedral: corresponding to "fire" elements, four positive triangles composition.
Zheng octahedral: corresponding to "gas" elements, eight positive triangles composition.
Positive square: corresponding to "soil" elements, six square compositions.
Positive twentieth body: corresponding to "water" elements, twenty positive triangles composition.
Double shedr: Corresponding to the mysterious "Ether" element, twelve positive five-dimensional composition.
Aristotle said to improve the five elements of Plato and finally became a representative of ancient Greek elements. He proposed the concept of the moon, and all objects below the moon are composed of four elements of soil, fire, water, gas; the celestial body above the moon is consisting of a pure fifth element "Ether".
He believes that soil and water are gravitational, always tend to the center of the universe; the gas and fire have a light nature, always rising to the natural position in the superior. However, these four elements are still not "final substrate", more basic is four different nature - cold, hot, dry, wet, their two or two combined with these four elements, such as wet and cold combination formation Water, heat and dry combination form fire. Different combinations of four major elements have formed everything in the world. And between the four elements can be transformed from each other.
