In this lively, fascinating, and often disturbing book, Raup reexplores the controversies of the Nemesis theory and investigates the issues--both scientific and philosophical --of mass extinction.

This volume tells the untold story of how observations of the cosmic microwave background radiation were interpreted in the decades following its serendipitous discovery, before the Hot Big Bang model became the accepted orthodoxy. The authors guide the reader through this history, including the many false trails and blind alleys that occurred along the way. Readers will discover how the Big Bang theory was shaped by alternative theories that exposed its weaknesses – including some that persist even today. By looking carefully at what it takes to reject an incorrect theory and the assumptions and processes at each stage, the authors examine the epistemological factors at play between an emerging scientific orthodoxy and since discarded alternatives. Their analysis of the cosmic microwave background provides a uniquely well-documented case study of theory building for a wide readership spanning cosmology, the history of physics and astronomy, and the philosophy of science more broadly.

This work is a unique introductory A–Z resource detailing the scientific achievements of the contemporary world and analyzing the key scientific trends, discoveries, and personalities of the modern age. An authoritative reference survey of the modern age of scientific discovery, Science in the Contemporary World is a scholarly yet accessible chronicle of scientific achievement from the discovery of penicillin to the latest developments in space exploration and cloning. Over 200 A–Z entries cover the full spectrum of contemporary science, with emphasis on its diverse nature. Within the last 50 years, medicine has eradicated the killer disease smallpox, but primarily because the virus can live only in humans. Space probes have revealed that on Europa, a moon of Jupiter, an ice-capped ocean with the potential to support life probably exists. Marvels from animal psychology and deep-sea exploration are also explored extensively.

Was Pope Pius XII a Nazi Sympathizer? For almost fifty years, a controversy has raged about Pope Pius XII. Was the Pope who had shepherded the Church through World War II a Nazi sympathizer? Was he, as some have dared call him, Hitler's pope? Did he do nothing to help the Jewish people in the grips of the Holocaust? In a thoroughly researched and meticulously documented analysis of the historical record, Ronald Rychlak has gotten past the anger and emotion and uncovered the truth about Pius XII. Not only does he refute the accusations against the Pope, but for the first time documents how the slanders against him had their roots in a Soviet Communist campaign to discredit him and, by extension, the Church. "Let those who doubt but read Rychlak, follow his exquisitely organized courtroon-like arguments. What Professor Rychlak brings to the forum are facts, not rhetoric; dates, not conjecture; evidence, not slander.... The world owes Ronald Rychlak a debt for bringing the truth to light." -- Rabbi Eric A. Silver "In his well-crafted pages...the portrait that emerges is one of an extraordinary pastor facing extremely vexing circumstances, of a holy man vying against an evil man, of a human being trying to save the lives of other human beings, of a light shining in the darkness." -- John Cardinal O'Connor (1920-2000) Archbishop of New York (from the Foreword to the first edition) "I have read many books on Pius XII, and this is by far the most dispassionate in laying out the context, relevant facts, accusations, and evidence pro and con. The book is highly engaging because it is filled with so many little-known facts. The research has been prodigious. Yet the presentation is as down-to-earth as it would have to be in a courtroom.... This is a wonderfully realistic book." -- Michael Novak, George Frederick Jewett Scholar in Religion, Philosophy, and Public Policy, American Enterprise Institute
