CONCENTRATION

The Body of Knowledge in Physics consists of two main parts: the object of study and the methodology used. The object of study in physics is physical natural phenomena, encompassing all phenomena in the universe, which includes the macroscopic world (cosmic scale) and the microscopic world (atomic and sub-atomic scale, as well as molecules and materials). Consequently, from an object perspective, physics is a very broad science.

The breadth of physics studies is then broken down into a number of sub-sections, including Particle Physics (Sub-Nuclear), Nuclear Physics, Atomic and Molecular Physics, Materials Physics, Geophysics, Physical Oceanography, Atmospheric Physics, as well as Astrophysics and Cosmology. These different objects of study, from the perspective of physics, are interwoven by a common conceptual approach focusing on the dynamics/mechanics aspect. In addition to the division of physics fields based on the object of study, the science of physics can also be divided based on the methodology used. There are three methodologies employed in physics: Theoretical Analytic Methodology, Computational Methodology, and Experimental Methodology. The first two methodologies are then combined and named Theoretical and Computational Physics Methodology.

These two main parts of the physics body of knowledge then give rise to a number of sub-studies (sub-disciplines) of physics, including Theoretical Particle Physics, Experimental Particle Physics, Theoretical Nuclear Physics, Experimental Nuclear Physics, Theoretical Materials Physics, Astrophysics and Cosmology, and Experimental Materials Physics. Apart from the two main components described above, the interaction of physics with other sciences also gives rise to interdisciplinary studies in physics. For example, the application of physics in the health sector leads to studies such as Medical Physics, Health Materials Physics, and Health Instrumentation Physics.

Thus, the branches of the physics discipline are numerous, ranging from studying the microscopic world to the macroscopic world, including their relevance to the development of new technology (Applied Physics). Undeniably, all technological studies are always based on physics. The determination of study materials in a physics study program becomes a choice, adjusted to the needs and available resources. At the Doctoral Program in Physics, the research domains span as follows:

• Theoretical and Computational Physics
• Materials and Energy Physics
• Medical Physics
• Geophysics and Environment
• Instrumentation Physics
