Physics is the science of everything..!
Broadly, Physics involves the study of everything in Physical existence, from the smallest subatomic particles to the entire universe. 'Physicists' try to develop conceptual and mathematical models that describe interactions between entities (both big and small) and that can be used to extend our understanding of how the universe works at different scales. Studying for a Bachelor of Science & Master of Science in Physics gives a broad overview of the most well-established of these models, such as classical mechanics, thermodynamics, electromagnetism, and quantum mechanics, as well as the computational and experimental skills used in working with them.
Physics is a one of the most fundamental scientific disciplines
The main goal of Physics is to explain how things move in space and time and understand how the universe behaves. It studies matter, forces and their effects. The word 'Physics' comes from the Greek word ἡ φύσις, meaning 'nature'. 'Physics' can also be defined as "that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events".
Role of Physics in Development
'Physics' is very important in engineering and developing new technologies, such as aviation, electronics and weapons. One reason for starting the Mathematical field of calculus was to help develop Mechanics, a branch of Physics. Modern Physics connects ideas about the four laws of symmetry and conservation of energy, momentum, charge, and parity. Astronomy, now a part of Physics, is the oldest natural science. In the past it was a part of 'natural philosophy' with other fields of science, such as Chemistry and biology. During the scientific revolution, these fields became separate, and Physics became a distinct field of knowledge.
Advances in Physics
Advances in Physics often enable new technologies. For example, advances in the understanding of Electromagnetism, Solid-State Physics, and Nuclear Physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.!
