Physics is the science concerned with the study of matter and energy and their interactions in the fields of mechanics, acoustics, heat, electricity, magnetism, radiation, atomic structure, and nuclear phenomena. Physics is an experimental science, which creates theories that are tested, with the scientific analysis of nature and the universe to understand how it works.

Although the modern discipline of physics emerged in the 17th century with the works and theories of Galileo Galilei, Isaac Newton, Rene Descartes, and other natural philosophers, theories about how the universe works were put forward by Greek philosophers in Ancient Times. Eudoxus of Cynidus (400-347 B.C.), who was an associate of Plato, created a very complex astronomy in terms of his description of the movement of heavenly bodies.
