Which physical disciplines form the theoretical underpinnings of Astronomy?
Answer
Classical mechanics, thermodynamics, and electromagnetism.
Astronomy is situated firmly within the natural sciences, and its theoretical framework is deeply connected to fundamental physics. The mathematical rigor applied in astronomy, used for calculating things like orbital paths, distances, and energy output, is directly derived from established physical laws. Specifically, classical mechanics provides the laws of motion necessary for orbital dynamics; thermodynamics addresses energy transfer, crucial for understanding stellar interiors; and electromagnetism is essential for interpreting the light and other signals received from cosmic objects.
