Branches of Science

The natural sciences, the social sciences, and the formal sciences.

The formal sciences study formal systems and are governed by axioms and rules. There is disagreement about whether they are science disciplines because they do not rely on empirical evidence.

Applied sciences are disciplines that use scientific knowledge for practical purposes, such as in engineering and medicine.
