Science, Culture and the Search for Life on Other Worlds

This book explores humanity’s thoughts and ideas about extraterrestrial life, paying close attention to the ways science and culture interact with one another to create a context of imagination and discovery related to life on other worlds. Despite the recent explosion in our knowledge of other planets and the seeming era of discovery in which we live, to date we have found no concrete evidence that we are not alone. Our thinking abo...

Gravitational Lensing and Microlensing

This book provides a comprehensive and self-contained exposition of gravitational lensing phenomena. It presents the up-to-date status of gravitational lensing and microlensing, covering the cosmological applications of the observed lensing by galaxies, clusters and the large scale structures, as well as the microlensing searches in the Local Group and its applications to unveil the nature of the galactic dark matter, the search for ...

Video Astronomy on the Go

Author Joseph Ashley explains video astronomy's many benefits in this comprehensive reference guide for amateurs. Video astronomy offers a wonderful way to see objects in far greater detail than is possible through an eyepiece, and the ability to use the modern, entry-level video camera to image deep space objects is a wonderful development for urban astronomers in particular, as it helps sidestep the issue of light pollution. The au...

Black Holes: Thermodynamics, Information, and Firewalls

This book reflects the resurgence of interest in the quantum properties of black holes, culminating most recently in controversial discussions about firewalls. On the thermodynamic side, it describes how new developments allowed the inclusion of pressure/volume terms in the first law, leading to a new understanding of black holes as chemical systems, experiencing novel phenomena such as triple points and reentrant phase transitions. ...

GravItational Lensing of Quasars

The universe, in all its richness, diversity and complexity, is populated by a myriad of intriguing celestial objects. Among the most exotic of them are gravitationally lensed quasars. A quasar is an extremely bright nucleus of a galaxy, and when such an object is gravitationally lensed, multiple images of the quasar are produced – this phenomenon of cosmic mirage can provide invaluable insights on burning questions, such as the natu...

Notre univers mathématique - En quête de la nature ultime du Réel

Quelle est la nature ultime de la réalité ? Cette question obsède depuis des millénaires philosophes, théologiens et scientifiques. Dans ce livre, le cosmologiste Max Tegmark développe une idée qui semble a priori bien étrange: l'Univers n'est pas simplement décrit par les mathématiques, il EST un objet mathématique. Faisant le lien entre différentes théories en vogue en physique, en cosmologie, en informatique et en sciences cogniti...

The Early Years of Radio Astronomy

Radio astronomy has revolutionized the course of modern astronomy. Marking the fiftieth anniversary of Jansky's discovery in 1933 of extraterrestrial radio emission, Professor Sullivan asked many of the pioneers in the field to set down their versions of events and the people who made them. Each of the score of contributors seeks to give a good 'feeling' for the times to the great majority of readers who will not have experienced the...

Taking Back Astronomy

"This book is meant to be an introduction only - a starting point to a biblical view of the universe. . . . Who knows what amazing truths are waiting to be discovered if only the shackles of secular thinking are removed. Now is the time of discovery…" Take a breathtaking look at the universe that is comprehensive guide to the heavens! Sit back and explore the world at your fingertips in this book which: - Explains the scale and size ...

The Search for Exoplanets: What Astronomers Know

As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far. We are living during a new golden age of planetary discovery, with the prospect of finding many worlds like Earth. Most of the thousands of planets we'v...
