        Extenics is a new science, originally called Matter-element Analysis. It was established in 1983, by Professor Cai Wen, one of the national distinguished experts of China.

        As a transverse science, Extenics runs through natural sciences and social sciences. It studies the extensibility of things, the rules and methods for opening up things and then uses them for solving problems. The research objective of Extenics is the solving of contradictory problems of the reality world. Its basic theory is the extension theory containing matter-element theory and extension mathematics as its two pillars. The matter-element theory includes extension theory of matter-element and the transformation theory of matter-element. Extension mathematics, based on the extension set, is the quantitative tool of solving problems.

        Extenics has a special method of its own called the extension method. It contains the opening up method of matter-element (divergent tree, chain of resolving and combining, conjugate pair, correlative net and implied system); the transformation methods of matter-element (basic transformations and transformation operations, conductive transformation and compound transformation) and extension thinking methods (rhombus thinking method, transforming bridge method and key strategy method). The applied technology in all areas using extension theory and extension methods is called extension engineering.
