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.
When in Rome, do as the Romans do definition When visiting a foreign land, follow the customs of those who live in it. It can also mean that when you are in an unfamiliar situation, you should follow the lead of those who know the ropes.
Rome really came into prominence by becoming an empire after the second Punic war which ended in 201 BC. The date given for the fall of the western part of the empire is 476 Aâ¦D. So you could say that Rome ruled the western world for about 676 years. This is just a ball park figure because Rome had been expanding to an extent, before the Punic wars.
