Three Dimensional Affine Geometry - Wild Linear Algebra A - NJ Wildberger

Explore three-dimensional affine geometry in this 43-minute lecture from the Wild Linear Algebra series. Gain intuition about 3D space through parallel projections, coordinate systems, and the distinction between points and vectors. Examine the nature of space, the arithmetic basis of geometry, and the relationships between lines and planes. Delve into affine and vector spaces, with practical exercises to reinforce key concepts. Ideal for those seeking a comprehensive introduction to 3D geometry and its applications in modern physics and mathematics.
