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

------正文------
I strongly agree with the assertion above that no field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study.

In the fist place, with the development of science, many fields, such as chemistry, physics, biology, geography and materials science reveal a unity and could not be separated from each other. In fact, when we accumulate more knowledge and probe in the nature more comprehensively, we have found that the divisions between different fields are created by ourselves for convenience of our study but nature takes little account of these divisions. So, fields are in process of losing their sharply defined boundaries. Take the chemical realm for example. Now, there are a great many of branches emerging in the chemistry, which are typical cross-field science. The biochemistry, which does research on the chemistry of living organisms and life processes, has to combine knowledge from organic chemistry, physic chemistry, biophysics and molecular biology because as we know, even the simplest living thing is a complex chemical factory . The physical chemistry, which is fundamental to all the chemistry, deals with the application of physical laws to chemical systems and chemical changes. The scientists in a major area of physical chemistry examine the spectrum of electromagnetic energy emitted by the molecules and explain the molecular structure in the living things by the principles of quantum mechanics. We have seen more and more new realms of science that cross different disciplines. They fuse the knowledge and experience of the other fields and use them to solve the problems in their own study. The trend that the realms of science lose their boundaries and borrow from theories from outside is clearer than ever before.

Secondly, knowledge and experience brought by outsiders to the field of study is so important that they would promote the significant advance in one field. For example, Einstein just used mathematic method of modeling to demonstrate the relationship between mass and energy, which is summarized by the famous equation E=mc2 in his special theory of relativity. Later, his general relativity of theory extended the special relativity to accumulated systems and showed the gravity to an effect of acceleration. This mathematic method of modeling marked the creation of the modern physics. Hereafter, scientists use this way to discover more and more phenomena, such as black holes, antimatter. Without the application of mathematic in the study of physics, we could not get to where we are. If we define our study by a strict limit in the particular field and neglect the knowledge and experience from the outsiders, we could easily get to a dead end in the field or remain still in the past.

In sum, since the realms of science have converged together little by little and the knowledge and experience from the outsiders could motivate the progress of one field, it seems that no field of study nowadays could gain the advance in its limited boundary.
