Physics is the study of nature and its various mechanisms in the context of observing mass and its interactions in space and time. Mathematics is a cornerstone of this study and is used as a tool for modeling systems and making predictions. As the broadest of all sciences, Physics is often referred to as the “Mother of all Sciences.”

The word originates from the Ancient Greek word: physis, meaning nature. The Ancient Greeks were also one of the first to study this field in its fragments including: astronomy, chemistry and optics. The word physis comes from phuio from the Aeolic meaning: “to grow”. This then traces back to the Proto-Indo European word *bʰuH-, meaning: “to grow, to become, and to appear.”

Categories covered by this field can range from the properties of large galaxies all the way down to the behaviors of elementary particles. All these phenomena can then be explained by using other simpler physical phenomena and the core theories. Physical phenomena are considered occurrences that involve matter, energy or space-time. The core theories are the accepted ideas behind the way the universe will function such as Classical Mechanics, Relativistic Mechanics, Quantum Mechanics and Quantum Field Theory. These theories stand as accurate ways to model the real universe. In Physics, its theories are mathematical and they can be used to obtain both precise and estimate values for its results and predictions.
Examples of Mathematics modelling Physics: (fttb) Projectile Motion, Compton Scattering, Gravity, Simple Waves, Light Scattering.

A discipline may be considered one that is part of Physics if it aims to explain a behaviour of the Universe through empirical and scientific methods. The Scientific Method is the systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses, according to the Oxford English Dictionary.

The study of physics has many applications such as medicine and engineering. It has become one of the primary pushers of newer technologies. Naturally, the state of education has come to teaching physics and its related fields in public schools. Unfortunately, in many countries, the courses for sciences are optional and often unpopular. Fortunately, the knowledge has become widespread and well archived, ensuring they will never be forgotten.
