* Natural Sciences: These focus on the study of the natural world. They are further subdivided into:

* Physical Sciences: Deal with non-living matter and energy. This includes physics, chemistry, astronomy, geology, and meteorology.

* Biological Sciences: Deal with living organisms and their interactions. This includes biology, botany, zoology, ecology, and genetics.

* Social Sciences: These focus on the study of human societies and their interactions. They are further subdivided into:

* Anthropology: The study of human societies and cultures.

* Psychology: The study of the mind and behavior.

* Sociology: The study of social relationships and institutions.

* Economics: The study of how people make choices in the face of scarcity.

* Political Science: The study of government and political processes.

* History: The study of the past.

* Geography: The study of the Earth's surface and its inhabitants.

Formal Sciences: These are sometimes included as a separate category, dealing with abstract systems and formal reasoning. Examples include:

* Logic: The study of valid reasoning.

* Mathematics: The study of numbers, structures, and patterns.

* Computer Science: The study of computation and information.

It's important to note that these divisions are not always clear-cut. There is often overlap between different fields, and some areas of science may fall into multiple categories. For example, biophysics combines elements of biology and physics.
