G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

    The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.

    We like to imagine that it’s based on evidence and the results of fair tests. In reality, those tests are often profoundly flawed. We like to imagine that doctors are familiar with the research literature surrounding a drug, when in reality much of the research is hidden from them by drug companies. We like to imagine that doctors are impartially educated, when in reality much of their education is funded by industry. We like to imagine that regulators let only effective drugs onto the market, when in reality they approve hopeless drugs, with data on side effects casually withheld from doctors and patients.All these problems have been protected from public scrutiny because they’re too complex to capture in a sound bite. But Dr. Ben Goldacre shows that the true scale of this murderous disaster fully reveals itself only when the details are untangled. He believes we should all be able to understand precisely how data manipulation works and how research misconduct on a global scale affects us. In his own words, “the tricks and distortions documented in these pages are beautiful, intricate, and fascinating in their details.” With Goldacre’s characteristic flair and a forensic attention to detail, Bad Pharma reveals a shockingly broken system and calls for something to be done. This is the pharmaceutical industry as it has never been seen before.

    Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.

    

    ‘Hollywood: Did You Know?’ is a collection of tidbits of information about the content or making of around 400 movies, ranging from the earliest days of the silent era to the present time. I have utilised anecdotes and comments from scores of biographies (authorised and unauthorised), as well as Internet sources, magazine articles, interviews and TV appearances. If, like me, you are fascinated by the world of movies, particularly the days of the studio system, I think you shall find more than enough items here to satisfy your curiosity. I am currently researching a second volume along similar lines. For elderly readers I should point out that there is a considerable amount of ‘bad language’ herein, simply because I quote actors and actresses verbatim. For many of them (even the so-called ‘greats’), peppering their reminiscences with expletives is commonplace. I make no apology for this, however, for I think it is important to present these individuals as they really were, minus the studio hype that tended to elevate them to the status of flawless gods and godesses. Very few lived up to their glowing reputations, I’m afraid. Having said that, I believe that the temptations ever present for these men and women who were suddenly faced with enormous wealth and universal adoration, would test the resolve of most of us, saints and all. And saints have always been few and far between in Tinsel Town. When I published my first book (Hollywood Warts ‘n’ All Volume 1) in 2005, I was accused of ‘muck-raking’, of tarnishing the reputations of deceased stars who could no longer defend themselves. I still get the occasional brickbat along those lines even today, but times have changed. Over the past 20 years or so, hundreds of books have been published about the ‘good old days’ of the studio system; not only stars’ biographies, but accounts from a diverse range of previously unheard from sources. Maids, bodyguards, chauffeurs, secretaries, bell-hops, agents, family members and acquaintances of the rich and famous etc, now put their memories into print, confirming much of what I have been writing about for almost a decade and a half. Of course, there are still those who rail against anyone who deigns to question the ‘snow-jobs’ churned out by studio publicity departments down the decades; the standard complaint being the usual one – the dead cannot defend themselves. Well, there have been more books written about Napoleon Bonaparte and Hitler than most anyone else, yet no-one complains of either man being unable to defend himself. So, again I make no apolgies for anything included in this publication, unless the reader comes across an unforseen error I may have accidentally overlooked, in which case I apologise unreservedly.

    Sgt. Charles Black is a 35 year veteran of the Iowa State Patrol during those years he has had many experiences and he shares his favorites in this book. In 35 years I have seen a lot of changes from the name of the organization to the primary function. From hearses to ambulances to rescue units with EMT's. From paper list of stolen cars to computers.From no recorders to body cameras. From fist fights to gun fights.But human nature and the effects of drugs and alcohol remain the same.
