Abstract
Think Scientifically means to analyse a technical skill, to put it together scientifically and to express it with a scientif ical sentence. The reasen why engineers were unable to express their technical skill in scientific expression in the apprenticeship age, they did not need to express their skill in scintif ical sentences. So they did not train themselves in such way. Em ploying patent system changed it. As the same reasen, why artists cannot express their skill of disining in scientific expres sion in the present age, they do not need to express their skill with scintifical sentences. So they neither train such way nor think in such way. However, western composers in the apprentic eship age who knoticed they needed it made their musics exprwssed in musical notes.In Japan, artists in the field of design knowticed recently they need scientificall thinking when they designing. Then, it has been patented under the thinking. If they understand it, they can understand they can think their skill scinetif ically.
