Physics

Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. It seeks to understand the fundamental principles governing the universe.
Sub-categories:

Exploring the laws of motion and the physical behavior of bodies under the influence of a system of forces. Key to understanding everyday macroscopic objects.

Studying the physical phenomena associated with electrically charged objects and the laws of electricity and magnetism that define electromagnetic force.

Analyzing the behavior of particles at the atomic and subatomic levels where classical mechanics no longer applies. A foundation for modern physics.

Concerned with heat, temperature, and the statistical behavior of systems with a large number of particles, offering insights into the laws of energy conversion.

Encompassing both Special and General Relativity, this subcategory addresses the geometry of spacetime and the relativistic effects of motion and gravity.

Focusing on the physical properties of condensed phases of matter, such as solids and liquids, and understanding their structural, mechanical, and electronic properties.

Investigating the properties and interactions of atoms and molecules, and the science of light including lasers and photonics.

Also known as high energy physics, it involves the study of the fundamental particles that constitute matter and radiation, probing the building blocks of the universe.

Examining the constituents, structure, and interactions of atomic nuclei, as well as the processes of nuclear reactions and radioactive decay.

Understanding the behavior of fluids (liquids and gases) in motion and the forces that act on them. Applications span from weather forecasting to aeronautics.

Focused on the study of ionized gases, plasma, and their applications, including fusion energy research and astrophysical phenomena.

Integrating principles of physics and astronomy to explain the life cycle of stars, galaxies, and the evolution of the universe.

Exploring the origin, evolution, and eventual fate of the universe, encompassing theories about its structure, history, and the laws that govern its dynamics.

Applying physical methodologies to study the Earth's structure, composition, and processes, from seismic activity to the Earth's magnetic field.

Examining biological systems through the principles of physics, seeking to understand life at every scale from molecules to organisms to ecosystems.

Utilizing physics-based concepts and methodologies in medical diagnosis and treatment, including the development of medical imaging techniques and radiation therapy.
