Clifford, Kinematic, book iii.).
No better testimony to the value of the quaternion method could be desired than the constant use made of its notation by mathematicians like Clifford (in his Kinematic) and by physicists like ClerkMaxwell (in his Electricity and Magnetism).
There is a corresponding kinematic peculiarity, in that the connection is now not strictly rigid, an infinitely small relative displacement being possible.
From the purely kinematic point of view, the t of our formulae may be any continuous independent variable, suggested (it may be) by some physical process.
