1. Based on the type of knowledge sought:
* Natural Sciences: Focuses on understanding the natural world. This includes:
* Physical Sciences: Study the fundamental constituents of the universe and their interactions (e.g., physics, chemistry, astronomy).
* Life Sciences: Study living organisms and their processes (e.g., biology, ecology, zoology).
* Social Sciences: Studies human behavior and societies. This includes:
* Psychology: Studies the human mind and behavior.
* Sociology: Studies human societies and their structures.
* Anthropology: Studies human origins, cultures, and societies.
* Economics: Studies how individuals and societies make choices under scarcity.
* Political Science: Studies political systems and processes.
2. Based on the method of inquiry:
* Formal Sciences: Focus on abstract systems and reasoning, often using mathematics and logic. This includes:
* Mathematics: Studies numbers, quantities, and structures.
* Logic: Studies valid reasoning and arguments.
* Computer Science: Studies the design and analysis of algorithms, data structures, and computational systems.
* Empirical Sciences: Focus on observations and experiments to test hypotheses and gather evidence. This includes both natural and social sciences.
It's important to note that these categories aren't always strict, and there is overlap between them. For example, some areas of science may combine elements of both formal and empirical methods.
