• The history of mathematics is an important subject. It gives a context in which to view the results that one learns in math classes. Furthermore it shows that mathematics is, first and foremost, a human activity. In the historical development of Linear Algebra, we see that the concept of a vector dates back as early as the work of Bolzano in the beginning of the 19th century. Initially vectors were used in the study of geometry, giving a way to "coordinatize" space. Transformations on space often took the form of matrices, and this prompted the study of such matrix properties as determinants and canonical forms. Later, in the work of Poncelet and Chasles, a move was made to a coordinate-free, or synthetic, geometry. This was the beginning of the notion of an abstract vector space, in which one replaces concrete spaces by abstract spaces satisfying certain axioms, and in which matrices are replaced by linear operators on these spaces. Today the influence of Linear Algebra extends far beyond geometry, and the concept of an (abstract) vector space arises in a variety of contexts. Consequently, Linear Algebra has had applications to numerous areas of mathematics as well as many areas of physics.
