About this Book
The scientific study of energy and matter and the process of interaction with each other is known as physics. The energy could be gravity, light, motion, radiation or electricity as matter of fact it could be anything from the universe. It studies matter and could be anything from sub-particles (the particles which make up an atom and the particles which further make those particles) to galaxy or stars. Physics aims in understanding the universal behaviour.
Physics can be dated to thousands of years; it is the oldest academic disciplines. Earlier physics had always been a part of biology, chemistry, natural philosophy and even in some branches of mathematics. Since the revolution of the 17th century, natural sciences came out as a separate research program. Physics intercedes with many interdisciplinary researches that are not strictly defined. Physics often gives rise to many new ideas which at times explain the fundamental mechanism of sciences other than physics and opening up new possibilities of study in fields like philosophy and mathematics.
Physics plays a vital role in the offerings through developments in new technologies that happen because of hypothetical discoveries. Like, developments while understanding nuclear physics or electromagnetism showed the way to production of products like computers, television, nuclear weapons, domestic products etc. have helped in bringing about a drastic change in today’s society. Progress in mechanics inspired the growth of calculus whereas progress in thermodynamics helped in the growth of industrialization.
Physics utilizes the scientific methods to formulate and test theories which are based on the observations of the world.
Physics aims on using the outcomes of these experiments to formulate laws of science, which are normally conveyed through mathematics and then are used in predicting other occurrences.
Some of the main topics in the fundamentals of physics are Mechanics, Waves, Thermodynamics, Electromagnetism, Optics and Special Relativity. They are the main constituents of physics and the subject revolves around them.
