I am just wondering about the relationship between the imaginary unit and cross product since cross product with a unit vector N is equivalent to a quarter-rotation in the plane with normal N.

It is really helpful to learn the geometric meaning of the imaginary unit instead of remembering it is the square root of -1.

It is an very interesting way to interpret the imaginary unit.
