Landmarks and Vectors

This lecture introduces the concept of landmarks and guiding vectors, exploring their definitions and properties. It covers the relationship between guiding vectors and directors, as well as the characterization of landmarks in a space. The lecture also delves into the abscissa of a landmark in a given reference frame, providing examples and explanations. Furthermore, it discusses the role of landmarks in defining bases and the coordinate system. The importance of non-collinear vectors and coplanar rectors in space is highlighted, along with their implications in vector spaces.
