Physics, it is a broad field of science which studies about the matter, motion along with the behaviour of time and energy present in this wide phenomenon of the universe.It is considered as an offspring of mathematics and natural philosophy.
This particular area concerned with science, provide a basis for all other science streams like biology, chemistry or any others. Physics as a stream of science has described so many scientific laws and fundamental concepts.
This particular subject mainly focused on understanding the different fundamentals of universal behaviours.
It has an endless list of inventions in this revolution as in, astronomical creations, satellites, and various universal laws of motion, time, energy, gravitation and many more to count upon.
It is considered as one of the extensive and composite subjects of study. Physics also has many expanded branches under it, which has contributed in advancing the world we are living. But has a lot of scopes aligned for the candidates interested in this field of Physics.
So, looks like one’s interest: Have this read to know other broad aspects of physics and what the entire subject has in store for you like learning and career opportunities.
Antiquity of Physics:
The word ‘Physics’ originated from a Greek saying – ‘knowledge of nature’, and that is why it’s said to be a subject, which aims onto explaining out the universal behaviours.
Some of the ancient Greeks like Aristole, Socrates, and others are said to be the inventors of new physics, who further made the understanding of natural world easy for its further heirs.
Have you ever thought of the world without the necessities it has for its living beings here – No Right!
Because it seems weird, to imagine the world without these fundamental things like lights, television, music systems, vehicles, food storages, cooking essentials and more.
Physics is being around us for so long now. It is one of the oldest and unique academic disciplines. There are two core theories of physics sited which are:
- Classical physics:
Galileo Galilei, Issac Newton and many others became the known faces of inventions under this subject of science – physics during 16th and 17th centuries.
Scientific laws and inventions were made for a solar system, planetary bodies, and also many excellent works done upon telescopes. Later laws of motion, calculus, universal gravitational force, electromagnetics, mechanics, and thermodynamics made to have a change in the industrial revolution of the world.
- Modern physics:
This came into the picture during early 20th century due to some faults in classical physics theories. Max Planck for quantum theory and Albert Einstein for the theory of relativity considered as one of the major faces in physics.
Many theory establishments in this area of study came over after it, like speed calculations, light variations, photoelectric effect, black-body radiation. Along with these, many mathematical models for studying probabilities and groups were developed later.
In this world, physics is that field of science where inventions will never stop taking place. Because the universal behaviour will always keep changing, and scientists will combat each change with their outstanding inventions in line.
Extraordinary divisions of physics:
In today’s era which has an ever-changing factor in place, physics is one of the most innovative fields of science. It has started focusing on many other comprehensive aspects present in the world than just analysing universal behaviour.
