TABLE OF CONTENTS [Progress] has been made recently in finding "dualities" or correspondences between apparently different theories of physics. These correspondences are a strong indication that there is a complete unified theory of physics, but they also suggest that it may not be possible to express this theory in a single fundamental formulation. Instead, we may have to use different reflections of the underlying theory in different situations . This would be a revolution in our view of the unification of the laws of science .

The concept of view is a general and important tool in engineering in general and MOSES in particular. A view allows us to focus on an area of concern and ignore everything else. This chapter gives a definition, examples, and types of views, and describes some areas of further research.
In some important respects, the idea of a view as commonly understood is consistent with its use in MOSES. A view, according to the dictionary, is the extent or range of vision, a manner of looking at or regarding something. Informally, a view is defined in MOSES as a subset of information observed of one or more entities. The entities are collectively called the target or object of the view. The physical or conceptual point from which a view is observed is the viewpoint, which can be motivated by one or more observer concerns. Different views of the same target can...
