The history of this subject during classical and medieval times was indistinguishable from stellar astronomy. It has been distinguisable from stellar astronomy only in modern times. It was little studied in the 16th, 17th, or 18th centuries. The 19th century including the early 19th century, early mid 19th century, mid 19th century, late mid 19th century, and late 19th century can be connected. The 20th century including the early 20th century, early mid 20th century, mid 20th century, late mid 20th century, and late 20th century can be connected. The early 21st century including the early 2000s, late 2000s, and early 2010s can be connected. Its future has not yet been examined. |

SociologyPeoples of the world including nations, Western Civilization, Asiatic peoples, African peoples, and American Indian peoples can be connected. Communities can also be connected. Social structure and change including social change, social types, and social structure can be connected. Personal studies including the human body, psychology, and biography can be connected to this subject. Anthropology including social foundations, demography, physical anthropology, numan ecology, human geography, and particular groups may be useful. Culture including material culture, conceptual culture, and behavioral culture can be examined. Institutions including families, education, economics, government, and religion can be connected. Chemistry including chemical substances, chemical changes, and chemical systems is also vital in galactic astronomy. This is closely connected to cosmology, stellar astronomy, and solar system astronomy. Earth science including biology provides few applications. This is connected first to areas of physics. It depends on advanced understanding of mechanics. Particle mechanics and rigid body mechanics are generally not sufficient. Nonrigid body mechanics is required. Gravitation is somewhat. Thermodynamics including statistical mechanics, classical thermodynamics, and nonclassical thermodynamics is also important. Electromagnetism is also important. Relativity theory is connected, and quantum mechanics is also. The structure of matter is also important. |
