It's important to note that this categorization is not absolute, and some fields may overlap or fall under both categories. For example, environmental science draws on both natural and social science principles. Additionally, there are other categories of science, such as formal science (e.g., mathematics, logic) and applied science (e.g., engineering, medicine).
