Matrices,In the last chapter we saw that a linear transformation T: ℝ. → ℝ. could be represented (that is, was completely determined by) 9 numbers arranged in a 3 × 3 array. In this chapter we will study such arrays, which are called matrices. We will return to the connection between matrices and linear transformations in the next chapter.

Linear transformations,In physics when vectors are used by fixing a coordinate system and employing components, it is very important to understand how the components will change if the coordinate system is changed. A change of coordinates is best expressed in terms of transformations of vectors. The simplest such transformations are the linear ones.

Bewegungen in Flüssigkeiten und GasenThe phenomenon of indebtedness in the present-day world economy seems to be a new and important element of international economic relations. It has become grave since 1974. In the years 1974–84 the medium- and long-term debts in the world increased almost tenfold from $70bn in 1970 to $687bn in 1984.
