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.

From Biological to Artificial Consciousnessde more detailed studies of their colours, spectra and dynamics were undertaken principally at the Harvard, Lick, Mt. Wilson, Lund and Stockholm observatories. The main results available at the end of the war have been summarized by . [.] and by . [.].
