Physics is one of the core pillars of science which lays an important foundation to understanding all the basic concepts surrounding us. Physics is the branch of science which deals with the study of matter, its composition, motion, its behaviors, and patterns, through space and with time. It correlates every concept to energy and force. It includes the study of both macroscopic and submicroscopic matter.

The study of physics mainly focuses on finding a single set of laws governing the study of matter, motion, and energy at microscopic and subatomic levels, and also at the macroscopic level used in everyday life. However, all the laws are not the same, but all of them are interrelated to each other. Several different phenomenons are studied in physics: heat, motion, sound, electricity, magnetism, light, etc.

Scope of physics tries to simply explain all the recent advances taking place in the field of science and its correlation with the past developments. Physics has a vast scope and high chances of development; however, it cannot be explained in short but can be divided into two broad classes based on the size of its subjects. These two disciplines are microscopic physics and macroscopic physics.

Microscopic Physics	Macroscopic physics
This includes the study of microscopic bodies, that is small microscopic bodies having sizes in micrometers. Microscopic physics is also known as Modern physics. This includes the study of the following topics: Quantum Mechanics: It is very similar to macroscopic mechanics’ study. It is a branch of microscopic physics which deals with the study of microscopic bodies, their energies, and forces, and how they affect each other. It includes the study of motion, momentum, velocity, microscopic substances, etc. Theory of relativity: This theory is used to explain the relationship between objects in inertia, and things in motion.	This includes the study of macroscopic bodies, that is big bodies having big sizes. A few scientists specializing in Macroscopic physics were, Newton, Coulomb, Oersted, Ampere, Faraday, etc. Macroscopic physics is also known as Classical physics. This includes the study of the following topics: Mechanics: It is a branch of classical physics which deals with the study of macroscopic bodies, energies, and forces, and how they affect each other. It includes the study of motion, gravitational pull, momentum, velocity, etc. Electrodynamics: It is a branch of classical physics which deals with the study of electrical fields, and magnetic fields. This branch is used in DC motors, generators, capacitors, NMR, etc. Optics: It is a branch of classical physics which deals with the study of light and all the phenomena governing it. This includes reflection, refraction, scattering of light, absorption, etc. Thermodynamics: It is a branch of classical physics which deals with the study of heat, work, temperature, system performance, system changes, the work it may perform
This branch deals with the study of all the phenomena taking place at a smaller scale, such as atomic scale, and subatomic scale.	This branch deals with the study of all the phenomena taking place at a bigger scale, such as laboratory scale, terrestrial scale, and astronomical (Space) scale.

The excitement of physics explains the constant curiosity in the field of science and physics, which helps in the development and advancement of discoveries every day. A few recent advances which have unfolded in physics are mentioned below:

Plasma Physics: This branch of physics deals with the study of the interaction of the electric and magnetic fields with charged particles and fluids. This branch has been widely applied in the fields of space and astrophysics, controlled fusion, accelerator physics, and beam storage.
Cosmic Rays Physics: Cosmic rays are high-power radiations that are emitted in outer space. They are generated by the explosions in stars. Cosmic rays are mainly composed of protons.
Astrophysics: Astrophysics is a branch of physics that deals with the study of space. It applies the laws of both physics and chemistry to explain the origin, existence, and destruction of stars, planets, galaxies, nebulae, and other objects in the universe and space. Astrophysics creates physical theories for all the small to medium-size structures in the universe.

Acoustics: Acoustics is a branch of physics that deals with the study of mechanical waves in all the states of matter, gases, liquids, and solids along with other phenomena such as vibration, sound, ultrasound, and infrasound. Acoustics primarily studies the levels of pressure and the frequencies in the sound wave and further how this wave interacts with the environment. It studies the nature of the propagation of sound waves.
Computational Physics: Computational physics is the branch of physics that deals with the study of scientific problems related to physics using computational methods, that is, it combines computer science, physics, and applied mathematics to develop scientific solutions to complex scientific problems. Computational physics tries to combine the areas of bookish theory and experimentation of a traditional scientific investigation to produce fruitful results.
