Kinematical Basis of Galactic Dynamics,A correct kinematical description of the galaxy is a necessary first step before it is profitable to develop detailed dynamical theories. For example, if the motions in the galaxy are inward along the spiral arms the resulting dynamical theory will differ from one that explains circular motions.
