Different branches of physics with definition and books list

Physics is one of the greatest subject for the students as well as for the teachers. This subject is the king of science. Physics deals with the natural phenomena and their applications. Our website provides best contents related to basic Physics and Electronics. One can read physics related articles from our website. All the categories are showing on the menus at the top of this page. In this article, we are going to give a brief overview on the different branches of physics with definition and related books to study. Students ask for seven branches of physics. But there are more than those. You will find these in this article.

Different branches of Physics and related books

Here, I have arranged all the branches of physics alphabetically.


Astrophysics is a branch of physics which deals with the astronomical objects and phenomena. One can know all relevant facts on Earth, Sun, Galaxies and other stars in this branch of physics.

Books For Astrophysics with Amazon links

  1. Astrophysics for people in a hurry
  2. Astrophysics for young people in a hurry
  3. A brief history of time by Stephen Hawking (Re-written)

Classical Mechanics

Classical mechanics is also known as the Newtonian mechanics. This branch of physics describes the motion of classical particles or the macroscopic particles. All laws of classical mechanics are based on Newton’s laws of motion.

Books of classical mechanics with amazon links

  1. Classical mechanics by H. Goldstein (Pearson education)
  2. Introduction to Classical Mechanics with Problems and solutions by Cambridge university press

Current electricity

Current electricity is a branch of physics as well as engineering that deals with the electric current, voltage and related facts. This topic covers the motion of charge, ions, etc.

Books for Current electricity:

  1. For basic level:
  2. For advanced level:


Electromagnetism or electrodynamics is a branch of physics that deals with the electric charge, its properties, its effects and the effect of moving charges. Electrostatics, magnetostatics and electromagnetic waves are the main discussions in this part of physics.

Books for electromagnetism:

  1. Basic level:
  2. Advanced level:


Like current electricity, electronics is also a branch of physics as well as engineering. Electronics deals with the motion of electrons through semiconductors and vacuum tubes. In modern days, most of the devices like TV, Laptops, Computers, Smartphones, etc. are made of semiconductors and fall in the part of electronics.

Books for Electronics:

  1. Basic level:
  2. Advanced level:

Mathematical Physics

To express any natural phenomena physicists need to use mathematical calculations. Now, to perform those calculations they need mathematical tools. In this branch of physics, students can learn all the techniques for mathematical calculation.

Books for Mathematical physics:

  1. Basic level:
  2. Advanced level:

Modern Physics

In this branch of Physics, the physics of modern days are discussed. Here, the modern days refers to the days after 1900. Photoelectric effect, Semiconductor electronics, Atomic models, etc. are the main topics for discussion in this section.

Books for Modern physics:

  1. Basic level: Foundation of Modern Physics (Cambridge University press)
  2. Advanced level: University Physics with modern physics by Pearson

Nuclear Physics

Nuclear physics is a branch of physics which deals with atomic nucleus and all the phenomena occur inside the nucleus of atoms. Different nuclear reactions, Radioactivity and radioactive decays are the main topics to discuss here.

Books for Nuclear Physics:

  1. Basic level:
  2. Advanced level:


Opto means light. The branch Optics deals with all the phenomena that include light. That means reflection of light, refraction of light, Interference, diffraction, polarization of light etc. are discussed here.

Books for Optics:

  1. Basic level:
  2. Advanced level:

Quantum Mechanics

Quantum mechanics is introduced after 1900. This also fall in the branch of modern physics. But it has a wide range of discussion and therefore, it is now a different branch. Quantum mechanics is a branch of physics that deals with the motion of microscopic particles. It reveals the wave nature of matter particles like electron, proton, atom, molecule, etc.

Books for Quantum mechanics:

For Basic level:

  1. Quantum mechanics: The theoretical minimum (Basic book)

For Advanced level:

  1. Introduction to Quantum mechanics – Cambridge university press (Griffiths)
  2. Quantum mechanics by Wiley publisher

Statistical Mechanics and Thermodynamics

In statistical mechanics, the statistical or probabilistic approach is used to solve problems of a physical system having very large number of particles. In the Thermodynamics part, the dynamic nature of temperature is discussed.

Books for Statistical Mechanics:

  1. For basic level:
  2. For advanced level:
