Physics is a branch of science whose primary objects of study are matter and energy. Discoveries of physics find applications throughout the natural sciences and in technology , since matter and energy are the basic constituents of the natural world. Some other domains of study—more limited in their scope—may be considered branches that have split off from physics to become sciences in their own right. Physics today may be divided loosely into classical physics and modern physics. Elements of what became physics were drawn primarily from the fields of astronomy , optics , and mechanics , which were methodologically united through the study of geometry. These mathematical disciplines began in antiquity with the Babylonians and with Hellenistic writers such as Archimedes and Ptolemy. The move towards a rational understanding of nature began at least since the Archaic period in Greece — BCE with the Pre-Socratic philosophers.

As an educator and theologian, he led schools and advised governments across Protestant Europe through the middle of the seventeenth century. Comenius introduced a number of educational concepts and innovations including pictorial textbooks written in native languages instead of Latin, teaching based in gradual development from simple to more comprehensive concepts, lifelong learning with a focus on logical thinking over dull memorization, equal opportunity for impoverished children, education for women, and universal and practical instruction. Owing to his impoverished circumstances he was unable to begin his formal education until later in life.
