4."No field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study."

中文提纲
其他学科的经验知识很重要，但要依托于本学科的基础才能出成就
1，  其他领域的知识经验对本学科的significant advance很有帮助
2，其他领域的知识经验很重要，但必须先专于一门


Is it the quotation of the knowledge and experience of other fields that brings significant advance in the study of a certain field? I concede that, nowadays, much of the development of study is depend on such quotation. But the stable ground of the original field is also important. In my view, Based on the groundwork of one certain discipline, the knowledge and experience of other fields can contribute a lot to the significant advance.

On the one hand, the knowledge and experience of other fields are important to the study. People have noticed that the knowledge and experience of other fields could do a great flavor to what they are studying on. It may because that people always try to answer questions by the old experience, but most of the problems which still wait to be solved cannot be solved by this way. And the quotation of outsider can bring new mind and avoid the rigidity. So the scientists often need to learn from other fields. For example, in today's scientific study, the interconnected fields, in which the solutions of problems often need the knowledge of two or more relevant disciplines, are the most active areas. Among the scientists who received the Nobel Price of Economic of recent years, there are many who used the method and knowledge of math into the study of economic and have harvested encouraging fruits. Without knowledge and experience from outsiders, many studies cannot continue, let alone significant advance.

On the other hand, the stable ground of one certain field is also indispensability. After all, these problems which are to be solved are described in the terminology of their field. Unless having a deep understanding of this field, you will not even understand what the problems are. My major is Material Science and Engineering (MSE), which is an interconnected field of physics and chemistry and calls for knowledge of many disciplines. But the head of MSE always tell us (and I paraphrase):"All of you should first learn and get a solid ground of the basic knowledge of math, physics, and chemistry before deal with the problems which concern with electricity, biology or other disciplines." The relation between knowledge and experience of the original field and the outsider is just like the relation between roots and leaf of a tree; without the roots, there will be no leaf.

To sum up, it is necessary to consider questions by using knowledge and experience of another field, but it is also important to have a solid ground of the knowledge of field from which the questions are raised up.
