The use of helixes also represents

 In any venture one must consider or the size that is suitable to the characteristics or the environment of the venture...Any venture must be done with circumspection, and one must not be to over -enthusiastic.

Development projects were established to improve and modify the existing natural resources in order to render the utmost benefits for the country and general public...Sometimes, there might be defects in order for the projects to yield ultimate benefits. Therefore, before establishing any projects, it is important to carefully and thoroughly consider their pros and cons...Development of the nation must be carried out in stages, starting with the laying of the foundation by ensuring the majority of the people have their basic necessities through the use of economical means and equipment in accordance with theoretical principles. Once a reasonably firm foundation has been laid and in effect, higher levels of economic growth with development should be promoted. If we were to concentrate only on fast economic progress without allowing the plan of operation to harmonize with the conditions of the country and people, an imbalance in various aspects would be cause and may bring about failure in the end, as witness the serious economic crises currently faced by many a developed country.

So to be a tiger is not important. The important thing for us is to have a self-supporting economy. A self-supporting economy means to have enough to survive...

Symbolize that China is opening her arms to embrace

 The two cantilevers symbolize that China is opening her arms to embrace participants from all over the world. It also shows China’s opening-up attitude. The product of 2 and 7 is 14, indicating the session of this Congress.

At the lower right corner of the centerpiece picture under the “ICME-14” four Chinese traditional trigrams (guas) are used to write down number 3744 in octal system, which is 2020 in decimal system, indicating the year in which the Congress will be held. In addition, the binary code of “2020” can be read from the four trigrams: (0)11111100100. The octal system and the binary system connect the brilliant civilization of ancient China with modern science and technology.

Mathematical elements are extensively disseminated in the logo: the Gougu Theorem, even and odd numbers, the octal number system and the binary system, and so on. They are not only the achievement of ancient China, but also the content of teaching in modern elementary and secondary schools. The design is very geometric, particularly the centerpiece picture that consists of circles and helixes is centrally symmetric.

 The use of helixes also represents the concept of spiral rise in modern teaching theory. The centerpiece picture assumes the shape of “S”, meaning Shanghai, the city where the Congress will be held. Its momentum of moving forward indicates our proactive attitude.
