... If b2 – 4ac < 0, then the equation has no real solution. But in the complex number system, this equation will always have solutions, because negative numbers have square roots in this expanded setting. ...

Quaternions are turning tomb raiders on their heads
... method is thus more costly computationally and there is more room for errors to creep in. Representing rotations via axis and rotation angle has the problem that it’s very difficult to compute the composite of two such rotations. Composing rotations recorded as quaternions is easy, just use the rule ...
