描述.This book enables the reader to discover elementary concepts of geometric algebra and its applications with lucid and direct explanations. Why would one want to explore geometric algebra? What if there existed a universal mathematical language that allowed one: to make rotations in any dimension with simple formulas, to see spinors or the Pauli matrices and their products, to solve problems of the special theory of relativity in three-dimensional Euclidean space, to formulate quantum mechanics without the imaginary unit, to easily solve difficult problems of electromagnetism, to treat the Kepler problem with the formulas for a harmonic oscillator, to eliminate unintuitive matrices and tensors, to unite many branches of mathematical physics? What if it were possible to use that same framework to generalize the complex numbers or fractals to any dimension, to play with geometry on a computer, as well as to make calculations in robotics, ray-tracing and brain science? In addition, what if such a language provided a clear, geometric interpretation of mathematical objects, even for the imaginary unit in quantum mechanics? Such a mathematical language exists and it is called geometric a

Appendix,erefore, we can define the exponential function of the elements of a geometric algebra. In .3, we have four important types of elements (numbers): . (dual numbers, square to zero), . (square to −1), . (square to 1), and . (square to itself). Nilpotents are the easiest to deal with: the expansion (∗)

Euclidean 3D Geometric Algebra (,3),unit pseudoscalar . commutes with all elements of the algebra and squares to −1, and therefore, it is an ideal replacement for the ordinary imaginary unit (there are many “imaginary units” in GA). A pseudoscalar with such properties will appear again in .7, .11, … (see E10). Here we often use a very useful form of a multivector:

https://doi.org/10.1007/978-981-97-6117-3We know how to multiply unit vectors; therefore, we can try to find some objects to . them. For vectors in .3, we need three parameters (three coordinates), and the geometric product is noncommutative. Consequently, we can choose matrices; 2 × 2 complex matrices will be enough. Matrices are a common choice for various representations.
