"Indledning" handler om at lave tankebilleder, så læseren kan bevæge sig frit rundt i den krumme rumtid. "1. Det umålelige måles" handler om Pythagora, Euklid, Jordens kugleform og størrelse. "2. Jorden omsluttes" handler om ??? "3. Den virkelige verden" handler om ??? "4. Imaginære verdener" handler om ??? "5. Det krumme rum" handler om ??? "6. Det usynlige univers" handler om ??? "7. Tilbageblik: Det observerbare univers" handler om ??? "8. En ny dimension" handler om ??? "9. En galakse af former" handler om ??? "Efterskrift" handler om fysik og matematiks sammenflettethed med et vip med hatten til Richard Feynman. "Tak" handler om alle dem, der har hjulpet forfatteren under skriveprocessen. "Noter" gemmer på mange formler og tal og henvisninger - ganske nyttigt. "Register" er et udmærket opslagsregister. ??? The clever Dr. Osserman engages us laymen in a basic cosmological discussion - the twist being his use of Dante's description of the universe. We get by and by to the hypersphere, in which the universe is expanding from the pre-big bang singularity, and we have the imaginary three-torus, which may go some way to allowing the universe to infinite time and finite space. Also, we learn that the curvature of space is very real and a useful tool for measuring relative positions, not something abstract or metaphysical. Dr. Osserman describes a geocentric map, in which we put, say, San Francisco at the center, and all things lay at a distance from there, on a large circle. The outer rim of the circle, a large circumference, actually represents one point, the farthest point on Earth away from San Francisco. Dr. Osserman then compares this to a trumpet's horn on the way to defining and describing some of the relevant concepts. We are led by short, simple steps to a rudimentary understanding of some of the abstruse math used to describe the universe. For some of us, that's as much as we can hope for. For anyone interested in gaining a first toehold on the math and physics of current cosmology, take this book up. It will not disappoint, even as it educates. http://bassoprofundo1.blogspot.com/2010/07/poetry-of-universe-by-robert-osserman... aucune critique | ajouter une critique
Listes notables
In the bestselling literary tradition of Lewis Thomas's Lives of a Cell and James Watson's The Double Helix, Poetry of the Universe is a delightful and compelling narrative charting the evolution of mathematical ideas that have helped to illuminate the nature of the observable universe. In a richly anecdotal fashion, the book explores the leaps of imagination and vision in mathematics that have helped pioneer our understanding of the world around us.

En mi opinión, aunque los capítulos individuales son buenos, no siempre están bien unidos unos a otros. Quizá funcionaria mejor como una serie de capítulos sobre divulgación general sobre matemáticas de las ciencias espaciales que como un solo tomo con un solo tema. A pesar de ello, es ameno y se lee sin problemas en unas horas. ( )
