Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment
related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory. The disciplines of science are commonly divided into three major groups: formal sciences: the study of mathematics and logic, natural sciences: the study of natural phenomena, and social sciences: the study of human behavior and societies. Innovation in science drives the global economy in the form of trillions of dollars of products and services and jobs.
