Physics is the science of matter and its behaviour and motion. It is one of the oldest scientific disciplines, perhaps the oldest through its inclusion of astronomy. The first written work of physics with that title was Aristotle's 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 disciplines began in Antiquity with the Babylonians and with Hellenistic writers such as Archimedes and Ptolemy, then passed on to the Arabic-speaking world where they were critiqued and developed into a more physical and experimental tradition by scientists such as Ibn al Haytham and Abu Rayhan Biruni,
