This paper is an attempt to simplify and clarify the mathematical language used to express quaternionic quantum mechanics QQM. Barred operators represent the key to realizing a set of translation rules between quaternionic and complex quantum mechanics QM. These translations enable us to obtain a rapid quaternionic counterpart of standard quantum mechanical results. This is a preview of subscription content, access via your institution.

The invention of the calculus of quaternions is a step towards the knowledge of quantities related to space which can only be compared, for its importance, with the invention of triple coordinates by Descartes.

The quaternions are members of a noncommutative division algebra first invented by William Rowan Hamilton. The idea for quaternions occurred to him while he was walking along the Royal Canal on his way to a meeting of the Irish Academy, and Hamilton was so pleased with his discovery that he scratched the fundamental formula of quaternion algebra,. The set of quaternions is denoted , , or , and the quaternions are a single example of a more general class of hypercomplex numbers discovered by Hamilton. While the quaternions are not commutative, they are associative, and they form a group known as the quaternion group. By analogy with the complex numbers being representable as a sum of real and imaginary parts , , a quaternion can also be written as a linear combination. Note also that NonCommutativeMultiply i. A variety of fractals can be explored in the space of quaternions.
We discuss 3-D rotations by which one double-couple earthquake source can be rotated into another arbitrary double-couple.Reply
