The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation.
The scientific method has roots in the work of ancient Greek philosophers, but it was formalized in the 17th century by figures such as Francis Bacon and René Descartes.
The scientific method is the cornerstone of all scientific inquiry. It provides a systematic and logical approach to understanding the natural world and is used by scientists in all fields to test hypotheses and build knowledge.
