In fact astronomy and physics are still somewhat merged, some scientists calling themselves astrophysicists.<br /> | Astronomy was crucial to the development of [[safe]] and accurate [[navigation]] for ships, and observations of the movement of [[heaven|heavenly bodies]] lead to the theories we know call [[physics]].
