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.
In mid-February 2011 it snowed in Rome, it was sunny in Rome, it rained in Rome, it was 50+ degrees (F) in Rome, it was 30 degrees (F) in Rome. Sorry, but that is the way it is and we never let the weather dictate our travel plans. We'll be in Rome and Paris in February again this year.
