List of Branches of Science
What is Science
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. It employs empirical evidence obtained through observation and experimentation to understand the natural world and its phenomena. The main branches of science (also called 'ologies' as most of these end with 'ology') are given below
