Theoretical Tools for CMB Physics [PDF]

open access: yesInternational Journal of Modern Physics D, 2005
This review presents, in a self–consistent manner, those analytical tools that are relevant for the analysis of the physics of CMB anisotropies generated in different theoretical models of the early Universe. After introducing the physical foundations of the Sachs–Wolfe effect, the origin and evolution of the scalar, tensor and vector modes of the ...

Undecidability and Intractability in Theoretical Physics

Physical Review Letters, 1985
Physical Processes are reviewed as computations, and the difficulty of answering questions about them is characterized in terms of the difficulty of performing the corresponding computations. Cellular automata are used to provide explicit examples of various formally undecidable and computationally intractable problems.

Theoretical Physics and Mathematics

2018
Following the method of Galileo, Theoretical Physics uses Mathematics as natural and essential language to describe reality. But even Galileo would probably be surprised by the degree of success of the mathematical description of the world. Simple elegant laws like the Planck radiation formula agree with reality accurately over all the electromagnetic ...

Theoretical physics

Physics Today, 1965
The third annual Eastern United States Theoretical Physics Conference was held at the University of Maryland in College Park on October 30 and 31, 1964. The first and second conferences were held at the University of Virginia and the University of North Carolina, respectively.

Theoretical Physics: The constants of physics

Physics Bulletin, 1983
Assuming that the laws of physics are all manifestations of a single set of axioms, as at least every mathematical physicist must surely believe, then the theory that describes this unified picture must be able to predict not only every dependency of one parameter on another but also the value of any constant parameter in a physical relation.
