physical theory

Physical theory

A physical theory usually involves the attempt to explain a certain class of physical phenomena by deducing them as necessary consequences of other phenomena regarded as more primitive and less in need of explanation. The value of a theory depends on both the success with which it coordinates a wide range of presently known facts and its fertility in suggesting places to look for presently unknown phenomena.

The model that predicts that particle would introduce a set of five new elementary particles that interact only through the weak nuclear force, wrote Marco Cirelli of the Institute of Physical Theory of the French Atomic Energy Commission and Alessandro Strumia of the University of Pisa and Italy's nuclear physics institute in a paper posted August 28 (arxiv.
He offers as an example, "We understand why planets move in ellipses, why materials burn, why salt dissolves in water (when it does) when we have a physical theory that provides a causal mechanism.
Four French mathematicians briefly introduce the physical theory of rotating fluids--a significant part of geophysical fluid dynamics--to graduate students and researchers in mathematics, engineering, earth sciences, and mechanics.
Physical realism is the thesis that the world is more or less as present-day physical theory says it is, that is, a mind-independent reality that consists fundamentally of physical objects that have causal powers, are located in space and time, belong to natural kinds, and interact causally with each other in various natural kinds of ways.
The articles, some of which are based on lectures, include such topics as how the new classical macroeconomics responds to the "Lucas critique," why idealized models in economics have limited use, a response by the late Amos Funkenstein to Nancy Cartright's arguments for the primacy of the notion of capacity, the generalization of evolutionary theory by abstraction, the influence of analogical reasoning, the role of idealizations in physical theory, a systematic proposal for sorting out idealization and abstraction, a case study from China, inferential relations between sentences (yes, the IRS), theory structure, and minimal realism.
If you want to test physical theory, you want to push it to its extreme," says Michiel van der Klis of the University of Amsterdam.
The resultant view--epistemological physicalism--has it that although one cannot know everything just by knowing complete physical theory, everything is metaphysically necessitated by what one can know just by knowing such theory.
