Physics

 

Physic is a natural science; it is the study of matter and its motion through space time and all that derives from these, such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand the behavior of the world and universe.
Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy Over the last two millennia, physics had been synonymous with philosophy, chemistry, and certain branches of mathematics and biology, but during the Scientific Revolution in the 16th century, it emerged to become a unique modern science in its own right. However, in some subject areas such as in mathematical physics and quantum chemistry, the boundaries of physics remain difficult to distinguish.
Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy..
Physics covers a wide range of phenomena, from the smallest sub-atomic particles (protons, neutrons and electrons), to the largest galaxies. Included in this are the very most basic objects from which all other things are composed, and therefore physics is sometimes said to be the "fundamental science".
Physics aims to describe the various phenomena that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things we see around us to root causes, and then to try to connect these causes together in the hope of finding an ultimate reason for why nature is as it is.
Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism). However, further work in the 19th century revealed that these two forces were just two different aspects of one force – electromagnetism. This process of "unifying" forces continues today
