QED Prerequisites Geometric Algebra 14: The Pseudoscalar
In this lesson we introduce the basis element of the grade 4 part of the spacetime algebra: the pseudoscalar. ERRATA: At about 6:00 I do a demonstration and slipped into the (-1,1,1,1) metric convention for a moment when I said (gamma_0)^2 = -1 …. An easy mistake to make! The result is st

QED Prerequisites Geometric Algebra 15: Complex Structure
In this lesson we introduce the idea of "complex structure". Complex structure binds scalars with pseudoscalars, vectors with pseudovectors, and bivectors with other bivectors. Please consider supporting this channel on Patreon: https://www.patreon.com/XYLYXYLYX The software I usually u

QED Prerequisites Geometric Algebra 17 - Bivector products
We examine Bivector-Bivector products using the canonical bivector form. Then we do a bit of bivector-bivector multiplication practice in the second half of the lesson, with a focus on the signature of the resulting product. Please consider supporting this channel on Patreon: https://www

QED Prerequisites Geometric Algebra 24 Paravectors
In this lesson we discover yet another way to partition the components of a general multivector. In this method, the partitioning is entirely dependent on a choice of reference frame. That is \gamma_0 must be chosen and it represents the 4-velocity of an observer who is stationary in that

QED Prerequisites Geometric Algebra 16: Canonical Bivectors
In this lesson we handle a few errata and then decompose a general bivector into a canonical form. Take note: we study this decomposition using a *different* paper, one written by Hestenes, but this is just a small diversion from our main paper. Please consider supporting this channel o

Geometric Algebra - Duality and the Cross Product
In this video, we will introduce the concept of duality, involving a multiplication by the pseudoscalar. We will observe the geometric meaning of duality and also see that the cross product and wedge product are dual to one another, which means that the cross product is already contained w

Geometric Algebra - Linear Transformations, Outermorphism, and the Determinant
In this video, we will review some basic concepts from linear algebra, such as the linear transformation, prove important theorems which ground matrix operations, extend the linear transformation on vectors to higher-graded elements to bivectors and trivectors, and define the determinant o
