In everyday life and in art works, "symmetry" has more meaning, often represents a balance, meaning the proportion of harmony, which in turn with the graceful, dignified linked. Weyl's book first chapter speaks with a mirror symmetry, involving chiral various issues, there is a very rich content. You may recall, the 2001 Nobel Prize in Chemistry rewards main topic is "chiral molecule catalytic" issue. Today, the chiral drugs in the pharmaceutical market, a considerable share of organic molecules chiral symmetry is quite practical and popular topic. There are still many basic questions left unanswered, such as the basic material life of amino acids, nucleic acids high consistency of chiral (ie, chiral symmetry breaking) is how to begin?

Typically, strictly symmetrical construction, as far as possible on the surrounding environment has an asymmetric among. The public may be more interested in the Analysis of the molar culture, Egypt and China actual decorative art in symmetry. In the two-dimensional decorative pattern, a total of 17 different symmetry nature species. The authors say that in ancient decorative patterns, especially in ancient Egyptian decoration, it is possible to find all 17 kinds of symmetry pattern. By the 19th century, has transformed the concept of the group later, it was understood theoretically only 17 possibilities (Polya proof), and the ancients really exhausted all these possibilities. Weyl a word particularly noteworthy: "Although the number 5 Arabs for a long exploration, but they certainly can not be associated with any one has a double unlimited decorative design, the real center embed a five-symmetrical pattern, however. They tried a variety of easy to be fooled
