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.

Rome was dominated by a partnership of three men, known as the First Triumvirate from the Latin words for three and men. The partners were Pompey, Caesar, and Crassus. While Pompey strengthened his position at home, Julius Caesar (100-44 B.C.) sought additional fame abroad. In 58 B.C. he became the governor of Gaul (roughly modern France). In the next eight years Caesar's troops brought Gaul under Roman control.
