Advancements in a field of study and outside experts

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

        I strongly agree the statement that it is very difficult for one field of study advance greatly without the knowledge and experience of outsiders. After all,        every fields of study, in fact, will affront many problems which can only be solved by experts in other areas. Thus, using of the knowledge and experience of other areas is the key of getting progress.

        Turning first to chemistry. In the history of discovering elements, many significant discoveries, which exerted a vital influence on the realm of chemistry, owed to using of physical techniques and theories: alkali metals were discovered because batteries were invented and use in chemistry experiments; the discovery of the elements Rb. and Cs. was attributed to the technique advancement in the realm of optics; the radioactive elements were detected under the direction of radioactivity theory. By contrast, before these new physical techniques and theories were used, these new elements could never be detected by the traditional approaches in chemistry.

        Turning next to archeology. As we all know, any of excavations of a big tumulus could make a significant contribution in archeology. Admittedly, archeologists’ professional knowledge and technique should not be overlooked. After all, these discoveries about ancient civilization belong to the area of archeology. But, in my observation, a excavation of a tumulus cannot operate only by archeologists, but also by the expertise of biologists, chemists, geologists and so forth. By analyzing the rocks and dust, geologists can determine the age of the tumulus; and by analyzing the hair, skin, and bones of the body, biologists and chemists could find more information about ancient human beings. In a word, because of outsiders’ knowledge and experience, tumulus  take on great value for archeology.

        Finally, examples of the area of medicine also aptly illustrate this statement. In medicine, the various equipments which developed by techniques and theories of physics, biochemistry, and optics, can help curing diseases more quickly and efficiently. Without these equipments, medicine may stop developing and stay a low level; people may still be afraid of normal diseases, such as rheum, diarrhea and so forth, and beg for gods’ help.

        In sum, every fields of study are not unaided. They must have some sorts of relations. To get progress in any one area we must need helps come from other areas. Moreover, the outsiders could make the progress have more comprehensive meanings.
