What is Physics?
Physics is the science of how the universe works, from the tiniest particles to the huge galaxies. It covers matter, energy, forces, and the basic laws guiding everything in our surroundings. Physics tries to answer questions like: why things fall, the medium in which light travels, and what is energy.
Why Study Physics?
Physics exists in everything we do or everything we use. Whether it’s our smartphones, travelling, running or exercising. Physics allows us to learn about natural phenomena, design new technologies, and solve ordinary everyday problems. Physics gives us the knowledge and skills of problem solving, critical things, and maths, which are helpful in every career we choose.
What Career Opportunities Physics Students Can Explore?
- Engineering: Physics knowledge is essential in mechanical, civil, and electrical engineering for designing machines, structures, and electrical systems.
- Medical Physics: The application of physics to the medical field such as developing technologies for imaging, like X-rays and MRIs, or treatments for cancer.
- Environmental Science: Physics is really important for studying energy systems, pollution, and solutions to climate change.
- Astronomy: Physicists in astronomy researches about planets, stars, and other secrets of the universe.
- Teaching: Physics teacher at school or college levels.
Sub Fields of Physics
Following are some of the major subfields of physics, each dealing with different aspects of the physical world:
Classical Mechanics
This sub-discipline dives deep into motion and the forces acting on objects. It is the very basic sub field that explains how a ball bounces and how planets orbit the sun.
Electromagnetism
Electromagnetism is the study of electric and magnetic fields, their sources, and interactions. This branch offers insight into how electricity works, explains the behavior of magnets, and finds fundamental applications in motors, generators, and communication systems.
Thermodynamics
Thermodynamics covers everything about heat and energy. How energy transfers through one object to another using physics theories.
Quantum Mechanics
This is the area that deals with the study of particles in their atomic and subatomic forms. Quantum mechanics finds its application in modern technology, including semiconductors, lasers, and MRI machines.
Relativity
Relativity explains the motion of bodies at very high speeds and those under the influence of strong gravitational fields. This helps us phenomena like time dilation which are applied in fields such as astrophysics and global positioning systems.
Optics
Optics is the science of light and its behavior. The way light travels, reflects, and refracts, and with what materials it interacts. It forms the basis for technologies like lenses, microscopes, and fiber optics.
Nuclear Physics
Nuclear physics covers the study of the atomic nucleus, nuclear reactions, radioactive decay, and other related phenomena.
Geophysics
It applies physical principles to the study of the earth, its structure, and processes, including magnetic and gravity fields. Geophysics plays an paramount role in the understanding of earthquakes and volcanoes, as well as resource exploration.
