Potentials and Scopes of Learning Physics in Career
Physics, a core discipline, is the fundamental and foremost to all natural sciences. It is an exciting intellectual adventure that inspires one and expands the frontiers of knowledge about nature. It has been significant and influential through advances in its understanding that have translated into new technologies. Physics interact with the society and other disciplines such as Medicine, Chemistry, Agriculture, Engineering, and Mathematics etc. in many important ways. It helps in improving the quality of life by providing the basic understanding, necessary for developing new instrumentation and techniques.
Physicists try to figure out how nature works. They may design and perform experiments with lasers, particle accelerators, telescopes, mass spectrometers and other equipments. Based on observations, predictions and analysis, they attempt to discover the laws that describe the forces of nature, such as gravity, electromagnetism and nuclear interactions and interestingly the agreement between theoretical concepts and experimental results are progressively better and better. They also find ways to apply physical laws and theories to address problems in nuclear energy, generation and transfer of energy, electronics, optics, materials, communications, aerospace technology, and biology. Theoretical physicists do a lot of thinking and calculations on paper and on computer. Experimentalists on the other hand would spend time doing measurements in a laboratory. Theoretical and experimental physics are two sides of the same coin. These two areas guide each other and there is a constant interplay between the two. A prime example of the interplay between theoretical and experimental physics is the work done on the Higgs Boson. Theorized in 1964, its existence was only confirmed almost 50 years later. In
March 2013, particle physicists working at one of the world’s most expensive and complex experimental facilities to date, the Large Hadrons Collider (LHC) at CERN (the European Organization for Nuclear Research), were able to create Higgs bosons and other particles for observation and study.
Physicists are the standard bearers of technological advancement. A perfect example is that of electromagnetic waves and electronics that eventually matured into mobile phones. While a career in pure physics provides benefits, many physicists branch out into the financial world as analysts. They are sought after due to their problem-solving skills. Physics contributes to technological infrastructure and provides trained personnel to take advantage of scientific advances and discoveries.
As a career, Physics provide excellent opportunity in space physics, nuclear physics, particle physics, laser physics, optics, condensed matter physics, electronics, quantum physics, astrophysics, and nanotechnology etc. Research over a broad range of topics in space physics ranges from the Sun and solar-terrestrial relationships to the interstellar medium that involves both scientific analysis and the development of instruments and satellites. Laser physics is concerned with the construction and application of lasers, their design, and the physics involved in their future development. The huge growth in telecommunications over the last decade can be attributed to new technologies made available through fiber optics and lasers, and the conveying of information by light. Lasers and photonics have underpinned the revolutionary development in information technology and computing.
The carrier in astrophysics is important to society because it pushes the frontiers of our understanding of our own existence. For example, the research on dark energy is promising. It might not have direct implications for life on earth, but understanding what dark energy is, will give us essential clues about the nature of the universe and how it came to be. Nuclear Physics is an excellent choice of career for any promising young student of science and mathematics. Nuclear Physics research facilities at Inter University Research Centre and Bhabha Atomic Research Centre, act like a magnet for students who are attracted by the exciting science being conducted there. Nuclear physics studies the constituents and interactions of atomic nuclei. It is most commonly associated with nuclear power generation and nuclear weapons technology. However, the research has provided application in many fields including: nuclear medicine, magnetic resonance imaging, ion implantation in materials engineering and radiocarbon dating in geology and archaeology. Particle physics evolved out of nuclear physics and the two are typically taught in close association. Neutron radiography (N-ray) and X-radiography (X-ray) and tomography are complementary, non-destructive testing techniques. These techniques are used in many scientific fields, with each day delivering new challenges, opportunities and excitement; especially when applied to new fields of research and on the safe handling of radiation and its utilization for the benefit of mankind. Quantum physics or mechanics is a branch of physics which deals with physical phenomena at nanoscopic scales. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter.
The job of a physicist is to discover and improve upon current theories and technologies that may be used in the improvement of peoples’ lives in the future and so on. A major challenge is to keep up with the amount of information, technology development and research applications. If you are curious, have an enquiring mind and enjoy solving puzzles, then you are a potential candidate for a career in physics. Obviously you need to have passion and skill if you want to capitalize on these opportunities.
Once you have a degree in physics, a universe of opportunity awaits you. You may pursue a career in engineering, mining, IT or even in the biomedical and financial sectors: practically any industry that requires good analytical and logical thinking skills. Alternatively, you could pursue a research degree in any reputed Indian/Foreign University/Institute. These studies can lead to a career in industry, the possibility of launching of one’s own company or a full-time research career at a university or research centre’s such as National Physical Laboratory, Indian Institute of Technology, Bhabha Atomic research Centre, Inter University Accelerator Centre, Physical Research Laboratories, Defense Research and Development Organization & reputed Indian/Foreign Universities.
SGT University Gurugram is the right choice to pursue a degree in physics, because of its excellent infrastructure, highly qualified faculty and technical staff, front runner specialization courses such as Electronics, Condensed matter Physics and Nuclear Physics, cordial environment for inter-disciplinary research, long spread campus, well equipped laboratories, and excellent sports facilities.
