Have you ever realized that from what source do we get various principles as well as concepts related to different streams of sciences? If u spend some time while thinking , you will admit that psychology deals with the study of brain, biology merely refers to various biochemical reactions taking place in our body, biochemistry deals with the complex chemical reactions of human body, while chemistry is only molecular physics written in summary in a table. We can define molecular physics as the nuclear force not strong enough over basic physics. The four fundamental forces of physics that are present are considered to be classified into one major Grand Unified Theory of Physics.

Moreover,as we all know, the world could be defined with few related concepts. With the above knowledge, new rules are being set for defining various approaches for gaining knowledge regarding various research fields. In order to solve complex problems, one should follow the divide and conquer rule and that should be the method used for doing research work in a specific field. Suppose for example,I like to involve myself in doing research in the field of biology, then my first step would be to understand the subject of physics. After having enough knowledge on physics, my next step would be to study chemistry and thereafter having knowledge regarding organic chemistry.

After gaining knowledge about these subjects, a through study of biology is undertaken. To start with, we say that the essentials are always advantageous but it is true to say that various processes involved in education generally ignore this vital aspect of the learning process. As an example, a person working for getting the psychology degree only has to be familiar with some of the courses associated with biology and as such no or very rare courses in chemistry or physics.
