We will investigate the relationship between rotations in vector spaces of dimension at most four and multiplication of complex numbers or quaternions. We will see that complex unitary 2-by-2 matrices with determinant one, which is a subgroup of isometries of a complex two-dimensional vector space, and rotations of three-dimensional Euclidean space are closely related.
