Research is a way of looking for new information, new understanding, and new facts. A person who does research is called a researcher. Some researchers work in academia. Other researchers work for businesses, for organisations, or for the government. Research is often used for solving problems or increasing available knowledge. This can be done by testing theories and making observations. Research usually prefers to be systematic, organised, and objective. Research is used in many different fields of study such as science, mathematics, and the humanities.
