Book Description
Mixing memoir and visionary science, a leading astrophysicist’s groundbreaking personal account of her life and ideas Is the universe infinite or just really big? With this question, cosmologist Janna Levin announces the central theme of this book, which established her as one of the most direct, unorthodox, and creative voices in contemporary science. As Levin sets out to determine how big “really big” may be, she offers a rare intimate look at the daily life of an innovative physicist, complete with jet lag and the tensions between personal relationships and the extreme demands of scientific exploration. Nimbly explaining geometry, topology, chaos, and string theory, Levin shows how the pattern of hot and cold spots left over from the big bang may one day reveal the size of the cosmos. The result is a thrilling story of cosmology by one of its leading thinkers.

One knock at the door, and Stefania has a choice to make... It is 1943, and for four years, sixteen-year-old Stefania has been working for the Diamant family in their grocery store in Przemysl, Poland, singing her way into their lives and hearts. She has even made a promise to one of their sons, Izio -- a betrothal they must keep secret since she is Catholic and the Diamants are Jewish. But everything changes when the German army invades Przemysl. The Diamants are forced into the ghetto, and Stefania is alone in an occupied city, the only one left to care for Helena, her six-year-old sister. And then comes the knock at the door. Izio's brother Max has jumped from the train headed to a death camp. Stefania and Helena make the extraordinary decision to hide Max, and eventually twelve more Jews. Then they must wait, every day, for the next knock at the door, the one that will mean death. When the knock finally comes, it is two Nazi officers, requisitioning Stefania's house for the German army. With two Nazis below, thirteen hidden Jews above, and a little sister by her side, Stefania has one more excruciating choice to make. This remarkable tale of courage and humanity, based on a true story, is now a Reese's Book Club YA Pick!

Book Description
Surviving Hypoxia: Mechanisms of Control and Adaptation is a synthesis of findings and thoughts concerning hypoxia. The thermodynamics of hypoxia are discussed in detail, including acid-base balance and self-pollution resulting from the accumulation of anaerobic end-products. The book focuses on descriptions and discussions of common facets, contrasting solutions in a variety of physiological hypoxia defense strategies, including those shown by plants, invertebrates, and vertebrates. Special treatment is given to the distinctive problems that hypoxia presents to vulnerable organs such as the kidney, liver, and brain. It also addresses pathological events in addition to protective mechanisms. Clinical implications of basic research are examined in the book, which provides new insights into underlying pathological processes occuring in hypoxic-induced organ failure and indicates new paths for successful clinical intervention. Surviving Hypoxia: Mechanisms of Control and Adaptation is an excellent reference for all researchers interested in the physiological effects of hypoxia, underlying pathological events, and protective mechanisms.

Book Description
After literally stumbling into orbs appearing as bright as light bulbs in photographs he was taking at a spiritual retreat, Dr. Klaus Heinemann immediately sensed that he was onto something profound. There was no choice but to convince himself that his notion was on solid grounds. Heinemann looked at thousands of pictures he had taken earlier, and thousands more would be taken to test the hypothesis that these light circles are nothing less than emanations from Spirit beings. Dr. Míceál Ledwith had a similar experience after the orb phenomenon was first made known to him through the teachings of Ramtha. He began an intense and systematic study of orbs in all sort of situations, day and night, and in all sorts of atmospheric conditions, in order to discover all he could about their nature, the situations in which their presence could be most easily detected, and what implications they might have for our understanding of our own place in the cosmos. To date, he has amassed a collection of well over 100,000 images. In The Orb Project, Ledwith and Heinemann present their fascinating discoveries, along with practical tips that amateur digital photographers can use to photograph orbs and properly distinguish them from "false" orbs that are really dust or water particles. They offer guidelines on deciphering the orbs' various patterns, features, and characteristics, based on their extensive research. As Dr. Ledwith points out, once you develop a keen and sustained interest in photographing spirit entities, some quite interesting things begin to happen: the brain stops censoring these images, and you can begin to see with orbs with the naked eye -- in more color and detail than is visible to even a digital camera. Ledwith and Heinemann also explore communication with orbs and what their existence means to our lives. The implications of a realization that we are "surrounded by a cloud of witnesses" are enormous and incredibly hopeful for the world at large.

Book Description
NATIONAL BESTSELLER • From “the poet laureate of medicine" (The New York Times) and the author of the classic The Man Who Mistook his Wife for a Hat comes a fascinating exploration of the remarkable, unpredictable ways that our brains cope with the loss of sight by finding rich new forms of perception. “Elaborate and gorgeously detailed.... Again and again, Sacks invites readers to imagine their way into minds unlike their own, encouraging a radical form of empathy.” —Los Angeles Times With compassion and insight, Dr. Oliver Sacks again illuminates the mysteries of the brain by introducing us to some remarkable characters, including Pat, who remains a vivacious communicator despite the stroke that deprives her of speech, and Howard, a novelist who loses the ability to read. Sacks investigates those who can see perfectly well but are unable to recognize faces, even those of their own children. He describes totally blind people who navigate by touch and smell; and others who, ironically, become hyper-visual. Finally, he recounts his own battle with an eye tumor and the strange visual symptoms it caused. As he has done in classics like The Man Who Mistook his Wife for a Hat and Awakenings, Dr. Sacks shows us that medicine is both an art and a science, and that our ability to imagine what it is to see with another person's mind is what makes us truly human.
