Geometric Calculus In this lecture we introduce the core concept of the vector derivative. This is the natural extension of the gradient operator to geometric algebra setting, where it inherits the properties of a grade-1 vector. The separate inner and outer … Continued

Spacetime Algebra In this lecture we introduce the geometric algebra of Minkowski spacetime, or spacetime algebra. Historically spacetime algebra drove much of the early interest in geometric algebra, and this importance was recently celebrated in a new edition of David Hestenes’ … Continued

Applications to 3D dynamics In this lecture we apply the geometric algebra of three-dimensional space to problems in dynamics. The first step is to replace the concept of an ‘axial vector’ with that of a bivector. Quantities like angular momentum … Continued

Geometric Algebra in 3 Dimensions In this lecture we explore the consequences of our definition of the geometric product in three dimensions. We find that Hamilton’s quaternions arise naturally in the geometric algebra of three dimensions, but that the generators … Continued

Geometric Algebra in 2 Dimensions In this lecture we introduce geometric algebra through studying various products of vectors. Our goal is to find an associative, invertible product that allows us to multiply together two vectors. Complex arithmetic helps motivate the … Continued
