While the older or mathematical astronomy, so called, has had to do with positions and magnitudes and motions essentially, all expressible by the aid of suitable symbols in the form of more or less complex functions, the newer or physical astronomy has concerned itself largely with physical phenomena and appearances, the completest attainable record of which is essential to their successful interpretation.
