    From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity.Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy.Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe.

    It took a year to accumulate enough so that one could actually see it. Now there is so much that we don't know what to do to get rid of it. We have created a monster.The history of plutonium is as strange as the element itself. When scientists began looking for it, they did so simply in the spirit of inquiry, not certain whether there were still spots to fill on the periodic table. But the discovery of fission made it clear that this still-hypothetical element would be more than just a scientific curiosity?it could be a powerful nuclear weapon.As it turned out, it is good for almost nothing else. Plutonium's nuclear potential put it at the heart of the World War II arms race?the Russians found out about it through espionage, the Germans through independent research, and everybody wanted some. Now, nearly everyone has some?the United States alone has about 47 metric tons?but it has almost no uses besides warmongering. How did the product of scientific curiosity become such a dangerous burden?In his new history of this complex and dangerous element, noted physicist Jeremy Bernstein describes the steps that were taken to transform plutonium from a laboratory novelty into the nuclear weapon that destroyed Nagasaki. This is the first book to weave together the many strands of plutonium's story, explaining not only the science but the people involved.

    They shirk everyday responsibilities, abuse drugs and alcohol, take up criminal careers, and lash out at family members. In the worst cases, they commit rape, murder, and other acts of extreme violence as though they lack a conscience. What makes these men--men we all know, whether as faces in the news or as people close to us--behave the way they do?Bad Boys, Bad Men examines antisocial personality disorder or ASP, the mysterious mental condition that underlies this lifelong penchant for bad behavior. Psychiatrist and researcher Donald W. Black, MD, draws on case studies, scientific data, and current events to explore antisocial behavior and to chart the history, nature, and treatment of a misunderstood disorder that affects up to seven million Americans. Citing new evidence from genetics and neuroscience, Black argues that this condition is tied to biological causes and that some people are simply born bad. Bad Boys, Bad Men introduces us to people like Ernie, the quintessential juvenile delinquent who had an incestuous relationship with his mother and descended into crime and alcoholism; and John Wayne Gacy, the notorious serial killer whose lifelong pattern of misbehavior escalated to the rape and murder of more than 30 young men and boys. These compelling cases read like medical detective stories as Black tries to separate the lies these men tell from the facts of their lives. Bad Boys, Bad Men not only describes the warning signs that predict which troubled children are more likely to become dangerous adults, but also details progress toward treatment for ASP. This volume will be an essential resource for psychiatrists, psychologists, criminologists, victims of crime, families of individuals afflicted with ASP, and anyone else interested in understanding antisocial behavior.

    We know how it all turns out. But imagine if you were the people living it. If you didn't know He was coming back. If you were Mary and Martha after Lazarus died, you would have thought He came too late. If you were Peter, you would have been appalled that the Master would lower Himself into your mess to wash your feet. If you stood at the foot of the cross and heard it was finished, you would have believed it was.What shifted? What allowed them to discover hope within the hopelessness? The witness of their change in perspective teaches us of an unexpected Christ. One who shows up, turning defeat into victory, and despair into deliverance.If He did it for them, He will do it for you. The story of Easter teaches us the truth of Jesus in every unexpected season. Through Him, you can expect hope in unlikely places.

    The objective here is to explain science in a simple, attractive and fun form that is open to all.The first axiom of this approach was set out as follows: “We believe in the magic of science. We hope to show you that sci-ence is not a secret art, accessible only to a dedicated few. It involves learning about nature and society, and aspects of our existence which affect us all, and which we should all therefore have the chance to understand. We shall interpret science for those who might not speak its language fluently, but want to understand its meaning. We don’t teach, we just tell stories about the beginnings of science, the natural phenomena and the underlying principles through which they occur, and the lives of the people who discovered them.”The aim of the writings collected in this series is to present some key scientific events, ideas and personalities in the form of short stories that are easy and fun to read. Scientific and philo-sophical concepts are explained in a way that anyone may under-stand. Each story may be read separately, but at the same time they all band together to form a wide-ranging introduction to the history of science and areas of contemporary scientific research, as well as some of the recurring problems science has encountered in history and the philosophical dilemmas it raises today.Review“If I were the only survivor on a remote island and all I had with me were this book, a Swiss army knife and a bottle, I would throw the bottle into the sea with the note: ‘Don’t worry, I have everything I need.’”— Ciril Horjak, alias Dr. Horowitz, a comic artist“The writing is understandable, but never simplistic. Instructive, but never patronizing. Straightforward, but never trivial. In-depth, but never too intense.”— Ali Žerdin, editor at Delo, the main Slovenian newspaper“Does science think? Heidegger once answered this question with a decisive No. The writings on modern science skillfully penned by Sašo Dolenc, these small stories about big stories, quickly convince us that the contrary is true. Not only does science think in hundreds of unexpected ways, its intellectual challenges and insights are an inexhaustible source of inspiration and entertainment. The clarity of thought and the lucidity of its style make this book accessible to anyone … in the finest tradition of popularizing science, its achievements, dilemmas and predicaments.”— Mladen Dolar, philosopher and author of A Voice and Nothing More“Sašo Dolenc is undoubtedly one of our most successful authors in the field of popular science, possessing the ability to explain complex scientific achievements to a broader audience in a clear and captivating way while remaining precise and scientific. His collection of articles is of particular importance because it encompasses all areas of modern science in an unassuming, almost light-hearted manner.”— Boštjan Žekš, physicist and former president of the Slovenian Academy of Sciences and Arts
