The book is an overview of the major subfields and concepts in physics, including a brief outline of the history of physics and its subfields.

Physics (from Greek from φυσικός (phusikos): natural, from φύσις (fysis): Nature) is the science of Nature in the broadest sense. Physicists study the behaviour and interactions of matter and radiation. Theories of physics are generally expressed as mathematical relations. Well-established theories are often referred to as physical laws or laws of physics; however, like all scientific theories, they are ultimately provisional. Physics is very closely related to the other natural sciences, particularly chemistry. The book is an overview of the major subfields and concepts in physics, including a brief outline of the history of physics and its subfields.
