After a brief introduction, Chapters 2-4 are dedicated to the study of the Clifford algebra of Euclidean 3-dimensional space, Minkowski 4-dimensional space and pseudo-Euclidean n-dimensional space, and to the use of the Clifford numbers in the study of the geometry of such spaces (rotations, reflections, etc.).
Of course, it is difficult to visualize objects in the 4-dimensional space. So we restrict our attention to the 3-dimensional slice of the 4-dimensional reality, namely, to the space of depressed polynomials of degree 4, that is, to the real polynomials of the form [x.sup.4] + [cx.sup.2] + dx + e.
