Empirical knowledge is information gained through observation, experience, or experimentation. It relies on evidence that can be measured or tested, making it a fundamental aspect of the scientific method. This type of knowledge is often contrasted with theoretical knowledge, which is based on ideas and concepts rather than direct experience. In everyday life, empirical knowledge can be seen in how we learn from our surroundings. For example, a scientist conducts experiments to gather data about a chemical reaction, while a teacher observes how students respond to different teaching methods. Both rely on empirical evidence to draw conclusions and improve understanding.
