From which branch of physics like nuclear physics or theoretical physics the PhD will be more beneficial for career?

deependra1003 said:I mean by nuclear physics the practical work just like working around the reactors etc. So I just wanted to know whether I choose theoretical side of physics or the experimental one for better earning options?

e.bar.goum said:It's a pretty broad subject, but basically, a nuclear physicist is a person who researches the interactions between atomic nuclei when they get close enough together to interact via the strong force. Nuclear physicists will study anything from the shape and structure of nuclei (nuclear structure studies) through to the precise dynamics of what happens in nuclear reactions (nuclear reaction dynamics studies), to how nuclei decay, and when, (precise studies of e.g. Auger electrons through and measuring half-lives.)
Nuclear physicists can do absolutely fundamental science - "how does nucleon transfer effect the probability of fusion?" , "how do triaxial shapes evolve?", "how can we understand high spin isomers?", "what reactions can take place in supernovae?", "how do we make the next heaviest element?" through to absolutely applied science - "how can we use nuclear techniques to map soil erosion in farmland?", "how does the energy of Auger electrons affect their use in cancer treatments?", "how do the secondary reactions in heavy ion therapy add to the total dose to a cancer tumour?" (and yes, bomb stuff as well, and I imagine there's some nuclear physics jobs with designing new reactors too, but I'd think you'd also be an engineer).
Nuclear physicists can be theorists - "how can we model fusion in a microscopic manner?" - their main tool will be a supercomputer or they can be experimentalists - "how can we measure the evolution of quasi-fission with neutron number?" - their main tool will be a nuclear accelerator and some particle detectors. Sometimes, they can be both.
Oops. In fact, nuclear physics is the only physics where you consider all fundamental forces of nature (gravity comes into play for nuclear astrophysicists - neutron stars etc). I phrased that poorly. In terms of structure/reaction dynamics though, often you only worry about the strong and electromagnetic forces.Intraverno said:Wait, Nuclear Physics only covers the Strong Force? Who researches the weak and electroweak forces then? Cosmologists?
Nuclear physics is the branch of physics that studies the properties and behavior of atomic nuclei. This includes the structure, composition, and interactions of these tiny, densely-packed particles.
Nuclear physics is a specific subfield of physics that focuses on the study of atomic nuclei. Theoretical physics is a broader field that encompasses various branches of physics, including nuclear physics. Theoretical physicists use mathematical models and theories to explain and predict physical phenomena, including those studied in nuclear physics.
Nuclear physics has numerous applications in fields such as energy production, medicine, and materials science. For example, nuclear reactors use controlled nuclear reactions to generate electricity, and nuclear medicine uses radioactive isotopes for diagnostic and therapeutic purposes. Nuclear physics also plays a crucial role in understanding the structure and properties of materials, such as those used in electronics and construction.
Nuclear energy is produced through nuclear reactions, such as fission or fusion, which are studied in nuclear physics. The principles of nuclear physics help scientists and engineers design and operate nuclear power plants and other nuclear technologies.
Some current topics of research in theoretical physics include quantum mechanics, string theory, and cosmology. Theoretical physicists are also studying the behavior of matter at extreme conditions, such as high energies or temperatures, and the properties of dark matter and dark energy.
