172 Chapter Two. Vector Spaces (b) Produce an equation that is not dimensionally homogeneous (i.e., it adds apples and oranges) but is nonetheless true of any circle. (c) The prior item asks for an equation that is complete but not dimensionally homogeneous. Produce an equation that is dimensionally homogeneous but not complete. (Just because the old saying isn’t strictly right doesn’t keep it from being a useful strategy. Dimensional homogeneity is often used to check the plausibility of equations used in models. For an argument that any complete equation can easily be made dimensionally homogeneous, see [Bridgman], Chapter I, especially page 15.)
Chapter Three Maps Between Spaces I Isomorphisms In the examples following the definition of a vector space we expressed the intuition that some spaces are “the same” as others. For instance, the space of two-tall column vectors and the space of two-wide row vectors are not equal because their elements — column vectors and row vectors — are not equal, but we feel that these spaces differ only in how their elements appear. We will now make this precise. This section illustrates a common phase of a mathematical investigation. With the help of some examples we’ve gotten an idea. We will next give a formal definition and then we will produce some results backing our contention that the definition captures the idea. We’ve seen this happen already, for instance in the first section of the Vector Space chapter. There, the study of linear systems led us to consider collections closed under linear combinations. We defined such a collection as a vector space and we followed it with some supporting results. That wasn’t an end point, instead it led to new insights such as the idea of a basis. Here also, after producing a definition and supporting it, we will get two surprises (pleasant ones). First, we will find that the definition applies to some unforeseen, and interesting, cases. Second, the study of the definition will lead to new ideas. In this way, our investigation will build momentum. I.1 Definition and Examples We start with two examples that suggest the right definition.
