Natural science can be broken into two main branches: life science (or biological science) and physical science. Physical science is further broken down into branches, including physics, astronomy, chemistry, and Earth science. All of these branches of natural science are divided into many further specialized branches (also known as fields), and each of these is known as a natural science.

Despite being defeated by the Gauls in 387 BC, the Romans successfully fought back Gaulish raiding parties throughout the middle of the fourth century BC.
