Subject Demand

If something is more fundamental then its domain will be extremely wide compared to something less fundamental. In fact, the range of the scope of Theoretical Physics outmatches any known discipline in the history of human knowledge. It covers a remarkable range of magnitude of physical quantities. At one end, it studies phenomena at the very small scale of length (10 to the power -14 meter or even less) comprising of electrons, protons, etc.; at the other end, it deals with astronomical phenomena at the scale of galaxies or even the entire universe whose magnitude is of the order of 10 to the power 26 meter. The two length scales differ by a factor of 10 to the power 40 or yet more!!! The whole observable universe according to our current understanding is made of just 12 fundamental entities and their interactions. Which part of Physics deals with that? If we want to go even beyond that - which part of Physics we need to study? So, Quantum Electrodynamics, Standard model and General Theory of Relativity are the most fundamental of all known physics and they are part of what we call \"Theoretical Physics.\"

Career Roles

The scope of Theoretical Physics is probably the biggest in anything that a man could do in his life-time. It surpasses every other cerebral subject that man has ever contemplated. For example, Biology deals only with life and living organisms; Chemistry is all to do with elements, compounds as well as the changes they undergo during chemical reactions but Physics in general and Theoretical Physics in particular has something or the other to do with everything as it seeks to understand the whole universe. It tries to comprehend and explain how everything from the DNA in an organism to the stars and galaxies, are made up from the same fundamental constituents. Even Mathematics seems like a pillar and the tool and language of something greater, which is Theoretical Physics. A key difference between Physics and Mathematics is that since Physics is ultimately concerned with accounts of the material world, it assesses its theories by comparing the predictions of its theories with data obtained from observations and experimentations, whereas Mathematics is concerned with abstract patterns, not restricted by those observed in the real world. The distinction, however, is not always clear-cut. There is a large area of research intermediate between Physics and Mathematics, known as Mathematical Physics.

Job Fields

Jobs in Theoretical Physics are more research oriented. Job centers or workstations are more like research centers or laboratories where you will need to study, identify and extend the scope of the study of Theoretical Physics.
