	20th WCP: Mathematical Models of Spacetime in Contemporary Physics and Essential Issues of the Ontology of Spacetime
		Theories of spacetime in mathematical physics, while considering continua and metric manifolds, cannot explain the difference between time dimension and space dimensions, they are also unable to explain by means of geometry the unidirection of the passage of time, which can be comprehended only by means of thermodynamics.
		The continuity and logic of evolution of physics of spacetime reconstructed by Heller is apparent, owing to the use of the language of contemporary mathematics.
		Logical development of the physics of spacetime in Heller's view is exposed through the use of the theory of fibre bundle and the theory of differential manifolds.

	On the merits of mathematical models - Physics Today June 2006
		Physicists have deployed mathematical models of interacting entities for two purposes: to establish the existence and properties of such entities—for example, quarks and other subatomic particles—by comparing precise calculations with precise measurements; and to predict and understand the properties of systems, such as doped semiconductors comprising known entities.
		At one time, uncritical faith in mathematical modeling lent false plausibility to the notion that one might in fact measure the parameters, solve the equations, and thereby centrally control an economy.
		The modeling of institutional process is as interesting for its limitations as for its successes, precisely because the regularities left unexplained by pure process models (which we have characterized as "zero-intelligence" models) are potential mathematical regularities of behavior.

	Models [Internet Encyclopedia of Philosophy]
		Physical models are used throughout the sciences, from immunoglobulin models of allergic reactions to macroeconomic models of the business cycle.
		This is sometimes called a “mediating mathematical model” (Morton 1993) since it operates, in a sense, between the intractable Hamiltonian and the phenomenon it is thought to describe.
		When this model is simulated on a computer, the resulting phase portrait is very similar to the one that was reconstructed from the data in the lab.

	Mathematical physics Summary
		Physics and mathematics have always enjoyed a close relationship, beginning in the Renaissance with Johannes Kepler's (1571-1630) 1609 discovery of the three laws of planetary orbits.
		Mathematics became increasingly important to physicists during the latter half of the twentieth century, usually because the physical objects under investigation were inaccessible to experimental physics.
		The term 'mathematical' physics is also sometimes used in a special sense, to distinguish research aimed at studying and solving problems inspired by physics within a mathematically rigorous framework.

		The thermohydraulic processes in the ground are governed by coupled partial differential equations, which are solved by means of analytical and numerical methods.
		Several computer programs have been developed that deal with all aspects of the thermal processes, from fundamental particular processes to detailed three-dimensional simulation models with arbitrary time-dependent loading conditions.
		Other problems that involve similar equations are also studied, e.g., groundwater movement around a nuclear waste repository and convective heat and moisture transport in building materials.

	Mathematical models in physics - Wikipedia, the free encyclopedia
		Physical theories are almost invariably expressed using mathematical models, and the mathematics involved is generally more complicated than in the other sciences.
		Different mathematical models use different geometries that are not necessarily entirely accurate descriptions of the geometry of the universe.
		In engineering, physics models are often made by mathematical methods such as finite element analysis.

	Mathematical model - Wikipedia, the free encyclopedia
		models are used particularly in the natural sciences and engineering disciplines (such as physics, biology, and electrical engineering) but also in the social sciences (such as economics, sociology and political science); physicists, engineers, computer scientists, and economists use mathematical models most extensively.
		Linear vs. nonlinear: Mathematical models are usually composed by variables, which are abstractions of quantities of interest in the described systems, and operators that act on these variables, which can be algebraic operators, functions, differential operators, etc. If all the operators in a mathematical model present linearity, the resulting mathematical model is defined as linear.
		Mathematical modelling problems are often classified into fl box or white box models, according to how much a priori information is available of the system.

	Myswizard » Theoretical physics
		Theoretical physics employs mathematical models and abstractions, as opposed to experimental processes, in an attempt to understand Nature.
		The proposed theories of physics are usually relatively new theories which deal with the study of physics which include scientific approaches, means for determining the validity of models and new types of reasoning used to arrive at the theory.
		Note 1: Sometimes mathematical physics and theoretical physics are used synonymously to refer to the latter.

	The end of time \| Ask MetaFilter
		Mathematics is, at its purest, the exploration of an abstract mathematical universe.
		Newtonian physics were fine for describing things of speeds that we observe everyday, but when applied to things that were very close the speed of light relative to the observer, Newtonian physical models broke down.
		The physics community, as a rule, is relentlessly realist and in so being are inclined to a sort of Platonism, an idealism complementary to their realism.

		All physics is mathematical, in the sense that physics is a quantitative subject and mathematics is the language of physics.
		The mathematical study of mirror symmetry, and algebraic geometry in general, Algebraic geometry is expected to be even more useful and to benefit enormously from the supergravity-string theory-M-theory perspective and profusion of concrete and unexpected features.
		This development is of particular significance for physics, because it brings some relatively sophisticated mathematical methods into practical use for the solution of a wide range of physical problems in the quantization of complex systems with dynamical symmetries.

	IUPAP: C18: Report 2005
		The mandate of the C18 commission covers the mathematical studies of problems originating in, or relevant to physics, including mathematical models of physical systems, mathematical aspects of physical theories, and computational techniques.
		We have communicated with the main professional society in the area, the International Association of Mathematical Physicists (IAMP) which was made easy due to the fact that the vicepresident of the IAMP is a C18 member, and vice versa, the chair of C18 belongs to the executive committee of the IAMP.
		The first one should distinguish a person who enriched and impacted the field of mathematical physics, the second one a person who achieved a significant result within the last ten years with preference to individuals from an environment without a strong mathematical physics tradition.

	THE HARMONIC OSCILLATOR IN PHYSICS - AND THEN SOME
		Mathematical systems are, of course, the substance of physical theory and so that is not exactly a trivial result in terms of physics.
		The notion of "an infinitude" is a physically transcendental and theological fabrication, and it is a standard denizen of the world of science, most especially because science that relies heavily on mathematics.
		That is not really a question of physics, but one of metaphysics: physics is concerned with finding out how nature behaves, what the fundamental rules are, and stating the answer in a precise mathematical language, while metaphysics concerns itself with how or why the rules have the form that they do.

		"Scientific theories are models of one part of nature, and all models initially have a limited range of validity," said Kane in a presentation at the American Association for the Advancement of Science meeting in Philadelphia this week.
		His mistake was that he accepted the model as truth without comparing it to events in the real world.
		As an example, Kane cites the Standard Model of particle physics---the basic theory that defines the particles in an atom and the forces which hold those particles together.
