    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

    

    In this book you will find some shocking details of the great figures of science such as Newton, Galileo, Kepler, Copernicus and Kant, presented with the characteristic humor that only a popularizer of science as Sergio de Regules could bring to this wonderful collection of essays.

    Craig Canapari became a father, he realized that all his years of 36-hour hospital shifts didn't even come close to preparing him for the sleep deprivation that comes with parenthood. The difference is that parents don’t get a break—it’s hard to know if there’s a night of uninterrupted sleep anywhere in the foreseeable future. Sleepless nights for kids mean sleepless nights for the rest of the family—and a grumpy group around the breakfast table in the morning.   In It's Never Too Late to Sleep Train, Canapari helps parents harness the power of habit to chart a clear path to high-quality sleep for their children. The result is a streamlined two-step sleep training plan that focuses on cues and consequences, the two elements that shape all habits and that take on special importance when it comes to kids’ bedtime routines.   Dr. Canapari distills years of clinical research and experience to make sleep training simple and stress-free. Even if you’ve been told that you’ve missed the optimal "window" for sleep training, Dr. Canapari is here to prove that it's never too late, whether your child is 6 months or 6 years old. He's on your side in the battle against bedtime, and with his advice, parents and children alike can expect a lifetime of healthy sleep.

    It was only some sixty years ago that researchers discovered REM, the rapid-eye-movement cycle that's associated with dreams. In Nightmareland, Lex Lonehood Nover travels into the eerie borderlands where the unconscious, dreams, and strange entities intermingle under the cover of night, revealing wider and hidden aspects of ourselves, from the savage and frightening to the astounding and sublime.Encompassing accepted medical phenomena such as sleep paralysis, parasomnias, and Ambien zombies, and the true-crime casebook of those who kill while sleepwalking, to supernatural elements such as the incubus, alien abduction, and psychic attacks, Nover brings readers on an extraordinary journey through history, folklore, and science, to help us understand what happens when we sleep.

    Michael Terman, PhD, has devoted his career to studying the brain functions that feed these disorders. His discoveries in chronotherapy have been widely recognized as game-changers by the medical establishment, and his 2010 New York Times op-ed, “Sleeping (or Not) by the Wrong Clock,” shot to number one on the paper’s list of most-forwarded online articles. In Chronotherapy, Terman and McMahan reveal the heart of his findings, a powerful program that recalibrates our internal clocks—our exquisitely designed, natural sensitivity to the timing and brightness of light exposure. These delicate mechanisms are often decimated by the modern demands of a 24/7 lifestyle.Beginning with a questionnaire that pinpoints the problem areas, Terman helps readers decipher when their natural internal night begins and ends. The treatment process can then start, incorporating the power of natural light and, when necessary, supplemental light therapy. His approach has brought relief to thousands of sleep sufferers, as well as those burdened by bipolar disorder, seasonal affective disorder, depression, sleep disorders due to around-the-clock work schedules, and other impediments to vibrant health. For the first time, his findings are now available for a general audience, sharing the essential elements of chronobiology in clear, authoritative, scientifically grounded chapters that are easy to apply to a variety of situations.  Chronotherapy chapters include: PART ONE: TIME, SLEEP, AND RHYTHMSChapter 1: External vs. Internal TimeThe clock on the wall measures twenty-four hours every day, but the clock in your brain runs a little different. How can you help them work together?Chapter 2: The Pressure to SleepThe longer you stay awake, the more pressure you feel to sleep. But what if your inner clock says it is not yet ready for sleep?Chapter 3: Owls, Larks, and HummingbirdsWhat kind of “bird” are you? And once you know, how can that help you figure out when best to get stuff done?PART TWO: TIME, LIGHT, AND THE BRAINChapter 4: Getting Light into the BrainHow do your eyes pass signals to your inner clock, and what makes those signals so important?Chapter 5: Getting Light WrongSeeing light and being in darkness are basic daily experiences. But what happens when they come at the wrong times, and why does that have such negative consequences for mood, alertness, and sleep?Chapter 6: Geography and TimeEast or west, south or north, how can where you live have such a huge impact on your mood and sleep?PART THREE: INTERVENTIONSChapter 7: Healing Light How can light help you solve your sleep problems, have more energy, and feel more positive about life? Why do the details matter so much?Chapter 8: Nighttime Meds and MelatoninDo you rely on pills to get to sleep? They may not work, and they may be bad for you. But a new approach based on the brain’s inner clock holds great promise.Chapter 9: Hospitalized with DepressionWhen someone becomes so depressed they need to go to the hospital, what promise does chronotherapy offer for a quick turnaround and continued improvement?Chapter 10: Beyond Light: The Charge in the AirWhat is it about spending a day at the beach that gives you such a lift? And how can you use new technology to bring that feeling of wellbeing into your home?PART FOUR: STAGES OF LIFEChapter 11: The Promise of PregnancyYou are going to have a baby! You are thrilled, but a little apprehensive too. How can chronotherapy help you through the next nine months?Chapter 12: Strategies for Babies and ChildrenWhen your baby or child sleeps well and feels good, you feel better too. How can chronotherapy help you reach this goal?Chapter 13: The Challenges of AdolescenceAs a teen, why do you feel the need to stay up so late and sleep so late? What are the consequences for your mood, health, and schoolwork? What simple steps can you take to put your life on a smoother course?Chapter 14: In Later YearsDoes getting older have to mean being tired, sleeping badly, and feeling down? How can you or someone you care about reverse these trends by using light?PART FIVE: CHRONOTHERAPY IN YOUR LIFEChapter 15: Coping with Shift WorkWhat if your job puts you on duty when your inner clock says you should be asleep? How can chronotherapy help you stay awake, alert, and in a decent mood?Chapter 16: Racing the Clock, Racing the Sun You are traveling across the world and you need to be in high gear tomorrow. How can chronotherapy prepare you for the trip and help you recover from jet lag as quickly as possible?Chapter 17: Chronobiology in the Home and WorkplaceHow will the collaboration of chronobiologists and architects transform the places you live, work, and learn?Chapter 18: Dawn of a Circadian ScienceWhy is mainstream medicine so slow to put the insights of chronotherapy into practice?

    For the engineers who had to kill the well, this was like Apollo 13, a crisis no one saw coming, and one of untold danger and challenge. A suspense story, a mystery, a technological thriller: This is Joel Achenbach’s groundbreaking account of the Deepwater Horizon disaster and what came after. The tragic explosion on the huge drilling rig in April 2010 killed eleven men and triggered an environmental disaster. As a gusher of crude surged into the Gulf’s waters, BP engineers and government scientists—awkwardly teamed in Houston—raced to devise ways to plug the Macondo well. Achenbach, a veteran reporter for The Washington Post and acclaimed science writer for National Geographic, moves beyond the blame game to tell the gripping story of what it was like, behind the scenes, moment by moment, in the struggle to kill Macondo. Here are the controversies, the miscalculations, the frustrations, and ultimately the technical triumphs of men and women who worked out of sight and around the clock for months to find a way to plug the well. The Deepwater Horizon disaster was an environmental 9/11. The government did not have the means to solve the problem; only the private sector had the tools, and it didn’t have the right ones as the country became haunted by Macondo’s black plume, which was omnipresent on TV and the Internet. Remotely operated vehicles, the spaceships of the deep, had to perform the challenging technical ma-neuvers on the seafloor. Engineers choreographed this robotic ballet and crammed years of innovation into a single summer. As he describes the drama in Houston, Achenbach probes the government investigation into what went wrong in the deep sea. This was a confounding mystery, an engineering whodunit. The lessons of this tragedy can be applied broadly to all complex enterprises and should make us look more closely at the highly engineered society that surrounds us. Achenbach has written a cautionary tale that doubles as a technological thriller.
