For a long time, the encyclopedias were very heterogeneous. There are dozens to hundreds of book volumes without a coherent system, so that the reader is very difficult to read. I always wanted to write an encyclopedia about 300 page and summarizing all knowledge and link them to each other or systematic. This theory system used for study all subjects, and the big bang pattern or the tree's structure as scientific system. Its main point, indicate total sciences are unified. Above theory pattern was also clearly given by the crop circle. There are five levels and three main lines direction outward. At same level, the subjects tend to be closer to the others. The more closer, the more bigger the resistance, and all are separated by a wall in the middle, that they can't cross.
