is a branch of physics providing a description of the behaviour and interaction of matter and energy on the scale of subatomic particles, photons and certain materials at very low temperature
is the type of mathematics that deals with rates of change, for example in the slope of a curve or the speed of a falling object.
is the scientific study of matter and energy and the relationships between them, including the study of forces, heat, light, sound, electricity and the structure of atoms.
is based on the principle that all movement is relative and that time is a fourth dimension related to space.
is the science that deals with the relations between heat and other forms of energy.
is the scientific study of sight and light.
is the production of a magnetic field by means of an electric current, or of an electric current by means of a magnetic field.
is Physics that does not make use of quantum mechanics or the theory of relativity, e.g. Newtonian mechanics, Thermodynamics, and Maxwell's theory of electromagnetism.
