Physics is the study of matter and the motion through space and time. Physics is concerned with energy, force, the analysis of nature and how the universe behaves on many levels. It is one of the oldest academic studies. There are many concepts in physics which explain the fundamental principles of other sciences. Physics is referred to as the linking science to other disciplines.
During the industrial revolution energy needs increased; research in the fields of physics and thermodynamics expanded. In this period of time, the laws of thermodynamics, chemistry and electromagnetics were discovered. These strives in science led to the invention of the steam engine and later to the combustion engine used in vehicles.
Modern physics is concerned with the behavior of matter and energy under extreme conditions such as small and large scales. The modern study of physics was revolutionized by the physicist Max Planck. Mac Planck had ground breaking work in quantum theory. Albert Einstein had contributions to modern physics by his work in relativity. An example of modern physics is atomic and nuclear physics.
Physics covers a wide range of phenomena. These can range from elementary particles to super clusters of galaxies. Physics tries to describe various phenomena that occur in nature in terms of more simple models. Physics tried to connect the things observable to humans to their causes and make connections to things observed in everyday life.
