...by using an observer located at the origin of the coordinate system, equipped with a clock, who coordinates the arrival of the light signal originating from the event to be timed and traveling to his position through empty space.
Since we define motion in terms of inertial coordinates, these experiments imply that the propagation of light is isotropic in terms of the very same class of coordinate systems for which mechanical inertia is isotropic.
He begins with an inertial coordinate system x,y,z,t, and posits another system of inertial coordinates x”,y”,z”,t” with its axes aligned and with its origin moving in the positive x direction with speed v in terms of the original system.

 HighBeam Encyclopedia - Cartesian coordinates   (Site not responding. Last check: 2007-11-03)
In a plane, the point P is specified by the pair of numbers (x,y) representing the distances of the point from two intersecting straight lines, referred to as the x -axis and the y -axis.
The point of intersection of these axes, which are called the coordinate axes, is known as the origin.
In oblique coordinates the axes are not perpendicular; the abscissa of P is measured along a parallel to the x -axis, and the ordinate is measured along a parallel to the y -axis, but neither of these parallels is perpendicular to the other coordinate axis as in rectangular coordinates.

The coordinates x and y are defined as before, in some plane, and z is measured from the origin in a direction perpendicular to the (x,y) plane.
Polar coordinates also have an "origin" O as reference point, but instead of (x,y), they use the distance r from O to the given point P, and the angle φ ("phi"--Greek f) between the line OP ("radius"--hence the letter "r") and some reference line.
