Book Description
A symposium to celebrate the life of Bohdan Paczynski (1940-2007), Lyman Spitzer Jr. Professor of Theoretical Astrophysics at Princeton University, took place on 29-30 September 2007. Bohdan Paczynski impacted astronomy and astronomers alike with his innovative ideas, philosophies, and insight to astronomy, science and life in general. This volume has assembled thoughts, memories and scientific accomplishments influenced in one way or another by Bohdan, who was a Giant in his field. Nine friends, colleagues and admirers who have been touched by Paczynski personally, professionally, or both, contributed invited presentations. Topics in this volume include the influence of Bohdan Paczynski in the field of stellar evolution and variable stars, his crucial role in making the Optical Gravitational Lensing Experiment (OGLE) and the All Sky Automated Survey (ASAS) possible, and his revolutionary insistence on allowing anyone and everyone access to his stellar evolution code: The Paczynski Code. Also included are Bohdan's contributions to gravitational microlensing and the search for dark matter in the form of MACHOs. Particular emphasis is given to advances and unexpected discoveries from surveys such as MACHO, OGLE, and EROS. The impact Paczynski had on our understanding of gamma-ray bursts is also discussed. Finally, this celebration of Professor Bohdan Paczynski is completed with the addition of personal accounts of his life, brilliance, sense of humor, and inspiration to others. Paczynski's scientific contributions reach across all of astrophysics and bridge the gap between observation and theory. This book is of interest not only to those who knew him, but also to those who know of him and the immeasurable ways he left his mark on the community.

The Variable Man: Philip K DickHe fixed things--clocks, refrigerators, vidsenders and destinies. But he had no business in the future, where the calculators could not handle him. He was Earth's only hope--and its sure failure!The Misplaced Spaceship: Harry HarrisonIt might seem careless to lose track of something like a battleship but interstellar space is on a different scale of magnitude. A misplaced battleship in the wrong hands can be most dangerous.Youth: Isaac AsimovThey found the two strange animals the morning after they heard the thunder sounds. They knew that they could never show their new pets to their parents.Bread Overhead: Fritz LeiberThe Staff of Life suddenly anddisconcertingly sprouted wings--and mankind had to eat crow!Rainworm: Jakob ChapmanThe bond was only marred in one way. I relived her strongest memories and emotions: the explosion of Candeo--being flung from the inferno while the rest of her race sizzled in silence--the planet below a glowing brand.

Book Description
It is with great joy that we present a collection of essays written in honour of Jayant Vishnu Narlikar, who completed 60 years of age on July 19, 1998, by his friends and colleagues, including several of his for mer students. Jayant has had a long research career in astrophysics and cosmology, which he began at Cambridge in 1960, as a student of Sir Fred Hoyle. He started his work with a big bang, expounding on the steady state theory of the Universe and creating a new theory of gravity inspired by Mach's principle. He also worked on action-at-a-distance electrodynamics, inspired by the explorations of Wheeler, Feynman and Hogarth in that direction. This body of work established Jayant's rep utation as a bold and imaginative physicist who was ever willing to take a fresh look at fundamental issues, undeterred by conventional wis dom. This trait, undoubtedly inherited from his teacher and mentor, has always remained with Jayant. It is now most evident in his untir ing efforts to understand anomalies in quasar astronomy, and to develop the quasi-steady state cosmology, along with a group of highly distin guished astronomers including Halton Arp, Geoffrey Burbidge and Fred Hoyle. In spite of all this iconoclastic activity, Jayant remains a part of the mainstream; he appreciates as well as encourages good work along conventional lines by his students and colleagues. This is clear from the range of essays included in this volume, and the variety and distribution of the essayists.

Book Description
The Young Universe presents four major physical and astrophysical themes related to these extreme phases of the primordial universe. In particular, it presents the physics of the primordial plasma and the concepts of quantum and particle physics necessary to describe this extreme state. It discusses the cosmological background radiation and explores inflation, an extremely rapid expansion phase that is believed to have occurred very early in cosmological history and to have shaped our present universe. The book also provides a synthesis of the dark matter problem.

Book Description
How patterns--from diagrams of spacetime to particle trails revealed by supercolliders--offer clues to the fundamental workings of the physical world. Our universe might appear chaotic, but deep down it's simply a myriad of rules working independently to create patterns of action, force, and consequence. In Ten Patterns That Explain the Universe, Brian Clegg explores the phenomena that make up the very fabric of our world by examining ten essential sequenced systems. From diagrams that show the deep relationships between space and time to the quantum behaviors that rule the way that matter and light interact, Clegg shows how these patterns provide a unique view of the physical world and its fundamental workings. Guiding readers on a tour of our world and the universe beyond, Clegg describes the cosmic microwave background, sometimes called the "echo of the big bang," and how it offers clues to the universe's beginnings; the diagrams that illustrate Einstein's revelation of the intertwined nature of space and time; the particle trail patterns revealed by the Large Hadron Collider and other accelerators; and the simple-looking patterns that predict quantum behavior (and decorated Richard Feynman's van). Clegg explains how the periodic table reflects the underlying pattern of the configuration of atoms, discusses the power of the number line, demonstrates the explanatory uses of tree diagrams, and more.

Book Description
The Extravagant Universe tells the story of a remarkable adventure of scientific discovery. One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today. This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the "cosmological constant" to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape. Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.

Book Description
This discussion resulted from a dialogue which began some seven years ago between a physicist who specializes in astrophysics, general relativity, and the foundations of quantum theory, and a student of cultural history who had done post-doctoral work in the history and philosophy of science. Both of us at that time were awaiting the results of some experiments being conducted under the direction of the physicist Alain Aspect at the University of Paris-South. ! The experiments were the last in a series designed to test some predictions based on a mathematical 2 theorem published in 1964 by John Bell. There was no expectation that the results of these experiments would provide the basis for developing new technologies. The questions which the experiments were designed to answer concerned the relation ship between physical reality and physical theory in the branch of physics known as quantum mechanics. Like most questions raised by physicists which lead to startling new insights, they were disarmingly simple and direct. Is quantum physics, asked Bell, a self-consistent theory whose predictions would hold in a new class of experiments, or would the results reveal that the apparent challenges of quantum physics to the understanding in classical physics of the relationship between physical theory and physical reality were merely illusory? Answering this question in actual experiments could also, suggested Bell, lead to another, quite dramatic, result.
