Physics encompasses various branches, each delving into specific aspects of the natural world. Classical Mechanics explores the motion and forces governing macroscopic objects, while Quantum Mechanics unravels the intricate behaviors of particles on the atomic and subatomic scales. Electromagnetism investigates the interplay between electric and magnetic fields, shedding light on phenomena such as electricity, magnetism, and electromagnetic waves.
What is Physics?
Physics is a science that studies the properties of matter and energy and establishes the laws that explain natural phenomena, except those that modify the molecular structure of bodies. Within this science, there are numerous areas of study such as theoretical physics, nuclear physics, quantum physics, or astrophysics, among others.
The development of Physics dates back to the beginning of history, more than two thousand years ago. In history, physics was considered a part of mathematics, but its subsequent development has led it to be considered a science apart from mathematics. This occurred, mainly, in the 20th century, through the research of prestigious physicists, when the development of numerous important theories was achieved.
Examples of these important Physics Theories are the Theory of Quantum Electrodynamics or the Theory of Newton’s Laws . On the one hand, the theory of quantum electrodynamics included the participation of, among others, the famous physicist Richard Feynman. On the other hand, Newton’s laws were based on the speed of light, developed by the physicist Isaac Newton.
Despite their differences, all branches of Physics try to explain the functioning of the Universe, and mastery of almost all mathematics is also essential to try to explain any theory or applied law.
List OF 15 Main Branches Of Physics:
Here is a list of 15 branches of physics:
- Classical Mechanics
- Quantum Mechanics
- Relativity (both Special and General)
- Atomic Physics
- Nuclear Physics
- Particle Physics
- Plasma Physics
- Condensed Matter Physics
Branches of physics
As we have told you, Physics is a very broad science, within which we find some others. This is what we know as branches of Physics or types of Physics . Do you dare to discover the most important ones one by one? Let’s start!
Quantum Physics is one of the best-known specialties of the Physical Sciences . In fact, this type of physics is in full swing. We understand quantum physics (also called quantum mechanics) as that branch that derives from Physics and focuses on the study of matter in very small proportions .
These proportions occur at the molecular, atomic and even smaller sizes. Quantum physics has allowed us multiple discoveries such as electronics , lasers, among many others.
On the other hand, we find what is known as Nuclear Physics. This maintains a close relationship with quantum physics. Nuclear physics studies energy and the effect of the union or division of atoms.
Thus, thanks to Nuclear Physics we have been able to understand the origin, structure and behavior of atoms and, more specifically, their nuclei.
Astrophysics is another of the best-known branches of Physics . Specifically, this consists of a branch of physics that is responsible for the study of celestial bodies from the analysis of their properties and behavior . Without a doubt, Physics and the study of the Universe and the bodies that coexist in it have walked hand in hand since the beginning of history.
In this way, thanks to Astrophysics and its theorists, we have been able to understand the functioning and behavior of the Solar System , stars or galaxies , among others.
Medical Physics is that discipline that relates the scientific techniques and methods of Physics to relate them to the medical world, such as the diagnosis and cure of some diseases. In other words, those who are dedicated to Medical Physics are responsible for preventing, diagnosing and treating diseases using nuclear techniques and technologies and ionizing radiation . Do you know what this means?
Ionizing radiation is a type of energy released by atoms that allows the electron to be eliminated from an atom or molecule. This can lead to changes in the cells of an organism. Can you imagine what this can do? Correct: it can be devastating or healing!
Medicine uses these physical techniques to treat some diseases .
Closely related to the previous branch, we find Biophysics . This is the one that deals, from the perspective of Physics and its elements, with the study of living beings and their properties. Yes, as you think: Biophysics is the perfect mix between two fundamental sciences. On the other hand, Physics.
Specifically, if you specialize in Biophysics you will be able to work studying the “physical states of living beings”, but, in addition, you will find an explanation of the vital energy that they possess. It’s great!
Have you heard of Mechanics in Physics ? It’s another of its branches!
This branch of physics explains the movement of objects in space or the effect of different forces on them. Thus, thanks to mechanics specialists we have been able to find an explanation, among other things, for the movement and behavior of microscopic objects.
Within Mechanics , we can find other subdisciplines. Some of them are kinematics , dynamics and statics.
Thermodynamics is the last branch of Physics that we are going to talk to you about . Specifically, this branch of Physics orients its analysis to those phenomena linked to temperature , its variations, the generation and transmission of heat energy and the effects that these changes generate on bodies.
In addition to these branches of Physics , we could find some others such as Acoustic Physics or Optical Physics . Train yourself in any of them and relaunch your professional career as a physicist!
