**Some 50 years ago, the set theory was a new theory for public and was used in schools. There were books to teach parents how to help their children in this regards. Many mathematical problems were solved with this new theory. It is like invention of transistor and without them we had no mobile or internet. Some other invention like Romaine numbers were not as useful and was decorative. Recently, the people discuss about M theory again. They say if someone wishes something, he should imagine it and how he wants it and his dream could be realized. In the finance world, you need business plans asking you a lot of question on social and economic situations requiring a huge knowledge. Then it shows if the investment is correct or not. Or it is like making reduced size model of some project, but materials and computations are very important as well. Sometime later I wrote my recent article I studied Einstein gravity equation. It is a difficult formula to understand, at least for me. It shows the world is basically unsymmetrical. Suppose all is symmetrical, it is like moon movement be on a perfect circle around the earth. The mass disturbs the space. It is the same as complex numbers show. Every mass curve the space, more dense mass curves more. A particle is a wave itself. A curve with a radius of more and less infinity size. As particles move near each other, superposition of waves create greater waves. Somewhere they might vanish and somewhere they become denser. Would we like to move to a denser place? How far is it? Just I tried to write you a new article.**
