This is a substantially revised and updated new edition of a classic introductory textbook. Although there are a wealth of cosmology texts at postgraduate level, 'Cosmology' remains the classic introduction to modern cosmology for undergraduates. While designed as the main text for a course given at second or third year level, it is sufficiently self-contained for anyone with school science to understand. There is a strong emphasis on observational cosmology, with introductory chapters on the visible universe, our galaxy and other galaxies and the empirical basis for cosmological theory. After an account of the big bang model, there are chapters on the early stages of the big bang and galaxy formation. Finally, there are chapters on cosmological tests and on alternative theories. One feature of the book is its updated epilogue of twenty controversies in cosmology today. The latest results from the WMAP mission are included and a wealth of new material, including a stronger emphasis on the cosmological constant. It has an extensive glossary and the exercises have been substantially expanded. A stronger emphasis on the physical basis for cosmology is included throughout.

Drawing on exciting discoveries of the last forty years, Night Vision explores how infrared astronomy, an essential tool for modern astrophysics and cosmology, helps astronomers reveal our universe's most fascinating phenomena from the birth of stars in dense clouds of gas, to black holes and distant colliding galaxies, and the traffic of interstellar dust from the formation of our Solar System. While surveying the progress in infrared observation, astronomer Michael Rowan-Robinson introduces readers to the pioneering scientists and engineers who painstakingly developed infrared astronomy over the past two hundred years. Accessible and well-illustrated, this comprehensive volume is written for the interested science reader, amateur astronomer, or university student, while researchers in astronomy and the history of science will find Rowan-Robinson's detailed notes and references a valuable resource.

An encapsulation in nine numbers of all that modern astronomy has learnt about the universe. These cosmic numbers appear to be independent characteristics of our universe and include its age, the Hubble constant (a measure of its rate of expression), and the density of matter in the universe. Only one of the nine numbers is known with real precision, and four of them only poorly known. Difficult ideas like the origin of the elements, the General Theory of Relativity, quantum theory, and the standard model of particle physics, ideas which underpin modern cosmology, are explained in a simple way. While most of what we know has been learnt during the 20th century, Rowan-Robinson provides a historical perspective, paying homage to the achievements of the Greeks, Renaissance astronomers, and the age of Newton. The book ends with predictions of when all nine numbers will be accurately known.

A chilling account of Hugo Chavez's shadow war on the United States

The American government has shrugged off South American politics for nearly forty years. In the meantime, our neighbor to the south has grown into an unprecedented threat. Hugo Chavez, the current president of Venezuela and a self-proclaimed enemy of the United States, commands what even Osama bin Laden only dreams of -- but few Americans see him as a true danger to this country. This book argues that we should.

Chavez has the means and the motivation to harm the United States in a way that few other countries can, and he has declared an "asymmetric war" against America. He runs a sovereign nation that is the fourth largest supplier of oil to the United States. He enjoys annual windfall oil profits that equal the net worth of Bill Gates. He has more modern weapons than anyone in Latin America. He has strategic alliances with Iran, North Korea, and other enemies of America, yet he has duped many Americans -- from influential political and cultural leaders to ordinary citizens who benefit from his oil largess through his state-owned oil company -- into believing that he is a friend.

Drawing on two decades of experience working at the highest level of Venezuelan and American politics, Schoen and Rowan go behind the scenes to examine Chavez's efforts to subvert both the American economy and his own country's stability. Not only did he help drive the price of oil from ten dollars a barrel to more than a hundred dollars a barrel, he's sponsored and become increasingly involved in civilian massacres, drug running, money laundering, nuclear weapons proliferation, and terrorist training.

Schoen and Rowan have both the insight and the access to make a case not yet made in the American media. Over the course of the past decade while living and working in Venezuela as writers and political consultants, they've investigated Ch+vez's past, explored his family connections, and gone up against him in a series of elections. Their startling revelations about Ch+vez's rise to power and his reach into American politics make this the kind of urgent, newsbreaking narrative that will spark vital debate in the corridors of power.
