Modern science is typically divided into three major branches that consist of the natural sciences, which study nature in the broadest sense; the social sciences, which study people and societies; and the formal sciences(e.g., mathematics), which study abstract concepts. There is disagreement,:54 however, on the formal sciences being a science as they do not rely on empirical evidence. Disciplines that use science, such as engineering and medicine, are described as applied sciences.
