Science involves the study of natural phenomena in three main branches: biology, chemistry, and physics. It provides knowledge that is important to everyday life through applications such as communication technology, agriculture, transportation, and medicine. Different careers require expertise in different areas of science, for example engineers need strong skills in physics while doctors need a background in biology.
