Why CMB physics?
The aim of these lectures is to introduce some basic problems arising in gravitation and modern cosmology. All along the discussion the guiding theme is provided by the phenomenological and theoretical properties of the Cosmic Microwave Background (CMB). These lectures have been prepared for a regular Phd course of the University of Milan-Bicocca. e-mail address: [email protected]
متن کاملTheoretical tools for CMB physics
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 geometry is treated in both gauge-invariant and...
متن کاملWhy Nonlinear Biomedical Physics?
The two goals of Nonlinear Biomedical Physics are: firstly to show how nonlinear methods can shed new light on biological phenomena and medical applications and secondly to bridge the technical, mathematical, and cultural divides between the physical disciplines where these methods are being developed and the audience for their use in the biological and medical sciences.
متن کاملeveryday physics of extended bodies or why functionals need analyzing
functionals were discovered and used by volterra over a century ago in his study of the motions of viscous elastic materials and electromagnetic fields. the need to precisely account for the qualitative effects of the cohesion and shape of the domains of these functionals was the major impetus to the development of the branch of mathematics known as topology, and today large numbers of mathemat...
متن کاملOn Why-Questions in Physics
In natural sciences, the most interesting and relevant questions are the socalled why-questions. What is a why-question? A why-question is nothing else than a question in the form “Why P?” (or “Why is P true?”) where P is an arbitrary statement. There are several different approaches to why-questions and explanations in the literature, see, for example, [5], [6], [7], [15]. However, most of the...
