Delve into the fascinating world of three-dimensional rotations and Hamilton's quaternions in this second lecture of a three-part series. Explore the geometry of spheres, composition of planar rotations, and the relationship between reflections and rotations. Learn about vectors, dot products, and cross products as you build a foundation for understanding quaternions. Discover Euler's theorem on rotation composition and a unique method of adding spherical vectors for visualizing rotation combinations. This in-depth exploration prepares you for the final lecture on Hamilton's quaternions and their practical applications in graphics, video games, and aerospace engineering.
