José Maria de Heredia, Les conquérants Plan 1.1 Introduction Jusqu’à une époque récente, l’Homme a toujours eu la préoccupation de comprendre son environnement dans son ensemble, sans en avoir les moyens. Sur le plan observationnel, l’œil nu est limité à quelques centaines d’années-lumière, c’est-à-dire à la proche banlieue du Soleil (à peine un dix-millionième de l’Univers observable en distance ; l’Univers observable est l’ensemble de ce que l’on peut voir aujourd’hui, il est défini plus loin.
En volume, ce n’est plus que la fraction 10-21 de ce qui existe…). La cosmologie a considérablement évolué avec le temps, et avec les découvertes que les nouveaux instruments permettaient à mesure de leur invention. L’invention de la lunette, puis du télescope, ont ouvert le champ des étoiles d’abord, puis des nébuleuses et des galaxies. 1.2 Cosmologies antiques. Numerical Cosmology.

A history of COBE, the COsmic Background Explorer, in pictures. Cosmology is the study of the origin, current state, and future of our Universe. Astronomy and cosmology are very much mathematical sciences, but I have attempted to avoid higher math in these pages. In addition to the cosmology tutorial, there is also a relativity tutorial and extensive discussions on the age, density and size of the Universe.

Images for textbook now available here Course Overview: This class is designed to be an up to date summary of the last 10-20 years of observations relevant to Cosmology. Topics to be covered: The order in which the following topics will be covered as not yet been determined. The Robertson Walker Metric and the Basic Cosmological Equations: Within the context of General Relativity we need to define a framework for specifying a geometrical model of the Universe that can ultimately be determined by observations.
So if it seems like we don't know very much about Cosmology that would be a correct inference. How this Class Works All material used in class will be available through the course web pages. Grading Internet Resources For This Class Homework Assignments:
