aIn science,a theory is a reasonable explanation of observed events that are related.A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced.A good example of this is found in the kinetic molecular theory,in which gases are pictured ...
A. Specific concepts in the system field may change the concept of other fields. B. The presentation of relativity promotes quantum information science. C. The development of probability and stochastic process theory change the methodology of system and control engineering. D. The development of com...
aIn science, we generally state a hypothesis in the form of a “null hypothesis.” For example, if our theory is that “the greater the number of interest groups that form around an issue, the greater the attention paid to the issue by Congress,” the null hypothesis would be: “The ...
field theoryhilbert spaceA field theory is considered in which the Green's functions have singularities not on a cone but on a hyperboloid. The metric of the corresponding Hilbert space is indefinite. Equations of motion for the boson and fermion fields are derived. The theory goes over to ...
Molecular metaphors: the gene in popular discourse Geneticists deploy a striking range of metaphors to communicate their science, to promote its value and to suggest its social meaning to the public. So too... D Nelkin - 《Nature Reviews Genetics》 被引量: 101发表: 2001年 SCIENCE AND SOCIETY...

The theory has also featured in political science. Noted American sociologist James Chowning Davies incorporated the J Curve in models used to explain political revolutions, asserting that riots are a subjective response to a sudden reversal in fortunes after a long period ofeconomic growth, known ...
. And the questions do not necessarily test for understanding of, or compliance with, those canons.]Those first surprising studies sparked the growth of a major research tradition whose impact has been felt in economics, political theory, medicine and other areas far removed from cognitive science...
