Double Scaling Limit
In theoretical physics, a double scaling limit is a limit in which the coupling constant is sent to zero while another quantity is sent to zero or infinity at the same moment. The adjective "double" is a kind of misnomer because the procedure represents an ordinary scaling. However, the adjective is meant to emphasize that two parameters are simultaneously approaching singular values. The double scaling limit is often applied to matrix models, string theory In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interac ..., and other theories to obtain their simplified versions. Theoretical physics {{theoretical-physics-stub ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
