by John C. Mather and John Boslough (1996)
In 1990 and 1992, a NASA-led team of scientists from the Cosmic Background Explorer (COBE) project changed the way we view the universe. They showed that microwave radiation that fills the universe has an exquisite perfection that proves it came from the Big Bang itself. Even more spectacularly, they found tiny variations in its brightness that come from quantum sound waves in that great explosion, primordial seeds that would nucleate the growth of galaxies and make our own existence possible. Their discoveries drew standing ovations from scientists and made headlines around the world. In this no-holds-barred account, COBE's Project Scientist and originator John C. Mather and science writer John Boslough furnish intimate and startling details. They tell of the discovery of the cosmic background radiation and of the subsequent fifteen-year struggle to design, build, and launch the Cosmic Background Explorer (COBE) satellite. An eye-opening, riveting account with rare narrative verve, The Very First Light tells the story of COBE from start to finish, including an unwelcome controversy when one team member breached the project's publication policy and stepped into the limelight alone.

Une introduction abondamment illustrée à l'astronomie (Univers, système solaire, observation et exploration, vie extraterrestre). Des personnages de type BD animent la leçon tandis que des schémas, photographies et images de synthèse illustrent les aspects scientifiques. [SDM].

This book aims to give the non-specialist reader a general overview of what physicists think they do and do not know in some representative frontier areas of contemporary physics. It focuses on the fundamental problems at the heart of the subject, and emphasizes the provisional nature of our present understanding of things.

"Archeology is the science that probes the past few thousand years. Geology takes us back two or even three billion years. Beyond that is the realm of cosmology: the study of the beginnings of the Universe around us.". So begins a journey deep into the origins of time, the birth of galaxies, and all the way to the farthest realm, beyond the end of it all. The tour starts at the beginning, the very early Universe - with Silk's masterful account of the Big Bang Theory, culminating in the 1965 discovery of cosmic microwave background radiation. "This whisper of creation is the greatly faded relic of the primordial fireball..."

This textbook represents a new approach in the teaching of quantum physics. The first seven chapters present nonrelativistic quantum mechanics and its interpretation as well as perturbations and scattering theory. They include Dirac's and Feynman's formalisms. The chapter on symmetry treats gauge transformations, too. The quantum theory of angular momentum includes the isospin of leptons and quarks. It uses as a new tool the graphical spin algebra. The second part of the book is devoted to quantum fields: Boson fields including Higgs fields, Dirac's theory of Fermion fields, quantum electrodynamic and quantum chromodynamics. A brief review is appended to raise the students' interests in quantum cosmology. The readers will also find many detailed worked examples and many problems to test their own understanding.
