Physics

Physics is the study of matter and its movement through spacetime, along with other things like forces and energy.

Early Variations of Physical Sciences
Physics was the first known form of scientific experimentation and observation, most notably by the ancient Greek astronomers (Philosophy of Physics). No proof was needed to publish a theory, it only had to be reasonable and easily defended in a scientific court. Natural science was the first form of physics to involve experimentation, this was developed in the Middle East and Chinese regions. Classical Physics is when scientific reasoning and ma thematic reasoning were used in Europe in the 16th and greater centuries, and Modern Physics started with the works of Einstein in relativity and quantum mechanics.
