Book Description
In 1913, English physicist Henry Moseley established an elegant method for "counting" the elements based on atomic number, ranging them from hydrogen (#1) to uranium (#92). It soon became clear, however, that seven elements were mysteriously missing from the lineup--seven elements unknown to science. In his well researched and engaging narrative, Eric Scerri presents the intriguing stories of these seven elements--protactinium, hafnium, rhenium, technetium, francium, astatine and promethium. The book follows the historical order of discovery, roughly spanning the two world wars, beginning with the isolation of protactinium in 1917 and ending with that of promethium in 1945. For each element, Scerri traces the research that preceded the discovery, the pivotal experiments, the personalities of the chemists involved, the chemical nature of the new element, and its applications in science and technology. We learn for instance that alloys of hafnium--whose name derives from the Latin name for Copenhagen (hafnia)--have some of the highest boiling points on record and are used for the nozzles in rocket thrusters such as the Apollo Lunar Modules. Scerri also tells the personal tales of researchers overcoming great obstacles. We see how Lise Meitner and Otto Hahn--the pair who later proposed the theory of atomic fission--were struggling to isolate element 91 when World War I intervened, Hahn was drafted into the German army's poison gas unit, and Meitner was forced to press on alone against daunting odds. The book concludes by examining how and where the twenty-five new elements have taken their places in the periodic table in the last half century. A Tale of Seven Elements paints a fascinating picture of chemical research--the wrong turns, missed opportunities, bitterly disputed claims, serendipitous findings, accusations of dishonesty--all leading finally to the thrill of discovery.

Book Description
Written in a provocative, witty, and highly accessible style, this is not only a splendid general introduction to the central questions of consciousness and brain science, but also an answer to some of them. The author -- noted Glaswegian chemist A.G. Cairns-Smith -- believes our feelings and sensations are not simply alternative descriptions of neural events but have themselves evolved and have physical effects in the brain as well as physical causes. Secrets of the Mind portrays a vision of the world as it may come to be seen by a future science. Sand, sea water, air, and the atoms from which such materials are made are now well understood by science, but the same can not be said of our personal feelings, our sensations and emotions. Science tells us that these too must be forms of quantum energy if they evolved, yet is only now beginning to explain how.

Book Description
People, children especially, have been baffled, bewildered, and even outraged by the fact that Pluto is no longer called a planet. Through whimsical artwork and an entertaining dialogue format, Pluto’s Secret explains the true story of this distant world. Providing a history of the small, icy world from its discovery and naming to its recent reclassification, this book presents a fascinating look at how scientists organize and classify our solar system as they gain new insights into how it works and what types of things exist within it. The book includes a glossary and bibliography. Praise for Pluto's Secret "Pairing a lighthearted narrative in a hand-lettered†“style typeface with informally drawn cartoon illustrations, this lively tale of astronomical revelations begins with the search for Planet X.†? —Kirkus Reviews "This picture book offers a fresh, positive perspective on Pluto, showing that its change of status is not a demotion but a correction." —Booklist "Light-hearted imagining of a gregarious Pluto.†? —Bulletin of the Center for Children's Books "Fun reading... The book provides a factual history of our faraway 'dwarf,' and on its companion icy worlds, and on the discovery of Kuiper-like bands around other stars." —School Library Journal Award New York Public Library’s annual Children’s Books list: 100 Titles for Reading and Sharing 2013

Book Description
“With this beautiful, touching and utterly believable novel, seekers will be gently invited to encounter the divine and believers be encouraged to deepen their relationships with God. I loved this book and loved the characters!” -Richard Rohr, author of Everything Belongs In the tradition of the spiritual classics The Shack and The Screwtape Letters comes The Abbey - a debut novel from New York Times bestselling author of Jesus: A Pilgrimage and The Jesuit Guide to (Almost) Everything, James Martin, SJ, who provides a window into the spiritual journeys of three people seeking direction, showing us firsthand how God uses our worries, questions, and even anger to help us become whole. As he did in his previous bestsellers, Martin once again crafts a book that incarnates deep spiritual wisdom while being accessible and full of humor and grace, with characters such as: · A divorced single mom, Anne can sometimes barely cope with life and struggles to make sense of the death of her young son. · A former architect who had a promising career, Mark works as a handyman and wonders how his life got off track. · The abbot of the Abbey of Saints Philip and James, Father Paul sometimes questions how to best live a life that secludes him so thoroughly from the world. · At a Pennsylvania abbey, this unlikely trio will discover the answers they seek—a miracle of hope and understanding that bears witness to the surprising power of God to bring healing and wholeness to our lives.
