The Theory of Everything can not be found by focusing on a single field of science only, such as physics or astronomy, because most sciences are already characterized by some insufficiencies. For instance: in physics the dual particle and wave nature of light, and in astronomy the problems of the warping of space and the curved-like traveling of light must be solved. Necessarily, all these insufficiencies must be removed by the Theory of Everything.

On the other hand, this theory must also be able to answer the fundamental questions of all other thinkers such as philosophers, sociologists, scientists, mythologists, linguists, engineers, etc. Undoubtedly, most of these questions are for the purpose of INCREASING THE LIVING STANDARD OF MANKIND which can be considered as the final target of this theory in which mankind is the basic element. In other words, such a theory first of all shall enable human beings to know why they act, how they think, and how they came to be.

To find this theory, preferably we shall have confidence in the most positive science, namely "Mathematics". Therefore, in my opinion, we shall try to define the behavior of mankind by digits and simple mathematical relations and models. Fortunately, the history of basic element in our research is almost clear which can help us to control the correctness of our mathematical model at the early stages. If we would prove the correctness of our model, we should be able to answer the question that Professor Stephen Hawking raised in "A Brief History of Time" as follows:

"Is the Unified Theory so compelling that it brings about the causes of its own existence?"

If our answer to this question is "yes", we are on the right track and we can continue our research by collecting a more comprehensive algorithm for the purpose of analyzing the opinions and questions of other thinkers. Probably, in this stage we will need more complicated mathematical relations as a part of our model.

At the beginning we need to review a brief history of human's brain development.

Notes:
1- The word algorithm stems from al-Khwarizmi, the father of algebra. 

2- A fully developed embryo in the womb is compelled to be born. The duty of midwife is to help woman in childbirth. In fact, the midwife is responsible for the health of both child and mother.

It is our duty to have the role of skilled midwife in birth process of a "Theory of Everything".
