The natural sciences were once divided into two broad categories: the biological
sciences and the physical sciences. The biological sciences
focus mainly on living
things. The physical sciences focus mainly on nonliving things. However, because
we now know that both living and nonliving matter
consist of chemical structures,
chemistry is central to all the sciences, and there are no
longer distinct divisions
between the biological and physical sciences.
