As a result of its incorporation of astronomy, physics is one of the oldest academic sciences. While these natural sciences have been part of natural philosophy for much of the past two millennia, they emerged as distinct research endeavors during the Scientific Revolution of 17th-century Europe. Biophysics and quantum chemistry are only two examples of areas where physics crosses with other, more multidisciplinary fields of study. These and other academic subjects such as mathematics and philosophy can benefit from new ideas in physics since they frequently explain the underlying mechanisms explored by other sciences
Introduction & Meaning
Physics is a branch of study concerned with the structure of matter and the interactions of the universe's fundamental elements. The largest definition of physics (from the Greek physikos) is the study of nature at all scales, from the macro to the micro. Beyond seeing how objects behave when subjected to a specific force, astrophysics studies gravitational, electromagnetic, and nuclear force fields in depth. Its ultimate goal is to develop a few fundamental concepts that can explain and unite all of these different aspects.
A natural science, physics focuses on the matter, its basic elements, its mobility and behavior over time and space, and the associated phenomena of energy and force. In physics, understanding how the world works is the primary objective, making it one of the most fundamental scientific fields.
