Physics as defined in the dictionary is the science of the study of matter and energy and mutual interactions between them;
but in fact it deals with the science of asking many questions for everything around us from the smallest particles at all and even the planets and galaxies, and the search for answers by experiment, observation , And mathematical evidence. In this article we will review the most common disciplines of physics that every student should know in this field.
* Note: Specializations are not ranked by importance
Astrophysics
Is one of the branches of astronomy . If you want to say this is a link between the science of physics and astronomy, this particular science deals with the study of the physics of the universe including the study of the physical properties related to it such as density, temperature and composition and interactions of various celestial bodies such as stars, galaxies, outer planets, black holes, dark matter and energy The Dark.
2. Atomic physics (molecular and physics)
The study deals with the structure and properties of atoms and atoms, including the interpretations and theories developed to understand the structure and structure of the atom, starting with the Thomson, Bohr and Rutherford atoms, and the Schrodinger equation and quantum mechanics .
3. Biophysics
This course deals with the application of the principles and basics of physics in biology . This course is taught for the first group in the Faculty of Science in biophysics and biology. The applications of this science include bone density measurement, laser and ultrasound applications, medical devices design, X-ray radiography . This science is closely related to radiological physics.
Solid State Physics (Condensed-matter Physics)
It deals with the study of properties of solids such as electrical, insulating, thermal and flexible properties of these materials through methods such as quantum mechanics, crystallography, electromagnetism, and alloys.
5- Cosmology or cosmology
It deals with the study of the universe as a whole with its emphasis on its development and development from the beginning to the future. This science is closely associated with space science and astrophysics .
6- Geophysics
Is a link between physics and geology . This science deals with the application of the principles and theories of physics in geology, from its applications to the study of meteorology, the monitoring and tracking of earthquakes, the study of the Earth's magnetic field, and the study of tides.
This course is taught to students of the Department of Geology as an additional specialization or as a single subject for the students of the Geophysics Department. It is a very vital course for anyone who works in the field of oil exploration . It includes many other sciences, such as field geophysics and applied geophysics.
7. Theoretical Physics
This science deals with the use of mathematical models to understand nature and to explain and predict physical phenomena. One of the most famous branches of this science is mathematical physics, one of the most prominent scientists in theoretical physics Albert Einstein and Stephen Hawking.
8. Modern Physics
The term "Modern" in modern English means modern or modern but we do not want the literal translation of the word. When we deal with this science we find that it was created under the birth of new elements in physics such as quantum mechanics and relativity. The classical of physics in its understanding and interpretation.
That is, we can call modern physics "post-Newton" or the branch developed in the early 20th century based on new concepts that never existed before.
9 - Electromagnetism (Electromagnetism)
Is the section that deals with the study of the impact of the magnetic field on electric charges or on electrically charged par
