Struktur, Aufgabenstellung und Arbeitsweise,ity condition, magnitudes for vectors and “circles” looking like ellipses. This shows that a metric is non-unique for a given vector space and there is a need to consider vector spaces devoid of the metric.

Staat und technische Kommunikation.1. In each of the linear spaces, bases can be introduced and dimensions of the spaces determined. The coefficients of expanding a given quantity in the basis are called coordinates, not components, because the two notions can be ascribed to one vector and should be distinguished.

Electromagnetism in Space-Time,imensional vector space. The transition from three-dimensional space to a plane described in a previous chapter is helpful to perform the passage in opposite direction, namely from three to four dimensions, in Sect. 7.2. A distinguished vector protruding in the fourth dimension is necessary for this
