I particularly appreciate the candid and non-judgmental way she depicts teen sensuality and female desire . . . Much to discuss here in the age of #metoo." --Gabrielle Zevin, New York Times bestselling author From Carolyn Mackler, author of the Printz Honor-winning The Earth, My Butt, and Other Big Round Things, comes a story of what happens when the "happily ever after" turns out to be less than perfect. It's been five months since sixteen-year-old Virginia Shreves thought her life was finally back on course: she has come to terms with who she is both inside and out, and she's even started to rebuild her relationship with her older brother Byron, whose date-rape charge completely shattered everything. But just as she's getting used to the new normal, Virginia's world turns upside down again. Sparks with boyfriend Froggy Welsh the Fourth fade, her best friend Shannon bombshells bad news, and then the police arrest Byron. As Virginia struggles to cope, she meets Sebastian, an artist with his own baggage. The pair make a pact not to share their personal dramas. But secrets have a way of coming out, and theirs have the potential to ruin everything. In this follow-up to the acclaimed The Earth, My Butt, and Other Big Round Things, Carolyn Mackler brings Virginia's story satisfyingly full circle in a hope-filled tale of forgiveness, love, friendship, and the beauty in life's imperfections.

DOWNLOAD EBOOK →Cosmology - the science of the Universe at large - has experienced a renaissance in the decades bracketing the turn of the twenty-first century. Exploring our emerging understanding of cosmology, this text takes two complementary points of view: the physical principles underlying theories of cosmology, and the observable consequences of models of Universal expansion. The book develops cosmological models based on fundamental physical principles, with mathematics limited to the minimum necessary to keep the material accessible for students of physics and astronomy at the advanced undergraduate level. A substantial review of general relativity leading up to the Einstein field equations is included, with derivations of explicit formulations connecting observable features of the Universe to models of its expansion. Self-contained and up to date in respect of modern observations, the text provides a solid theoretical grounding in modern cosmology while preparing readers for the changes that will inevitably come from future observations.

DOWNLOAD EBOOK →Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place. “Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing?” One of the few prominent scientists today to have crossed the chasm between science and popular culture, Krauss describes the staggeringly beautiful experimental observations and mind-bending new theories that demonstrate not only can something arise from nothing, something will always arise from nothing. With a new preface about the significance of the discovery of the Higgs particle, A Universe from Nothing uses Krauss’s characteristic wry humor and wonderfully clear explanations to take us back to the beginning of the beginning, presenting the most recent evidence for how our universe evolved—and the implications for how it’s going to end. Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.

DOWNLOAD EBOOK →In this fascinating Very Short Introduction, popular science writer John Gribben tells the story of our growing understanding of galaxies, from the days before Galileo to our present-day observations of our many hundreds of millions of galactic neighbors. Not only are galaxies fascinating astronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own "Milky Way" Galaxy in detail, from the different kinds of stars that are born within it, to the origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxies collide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter. John Gribbin is one of the best-known current popular science writers. His many books include the acclaimed The Universe: A Biography, In Search of Schrodinger's Cat, and Science: A History. He has written for many newspapers and regularly contributes to radio and television documentaries and debates, and also writes science fiction novels. He formerly worked for Nature and New Scientist and is presently a Visiting Fellow in Astronomy at the University of Sussex. 1. A Very Short Introduction 2. The Great Debate 3. Our Island 4.

DOWNLOAD EBOOK →A new look at the first few seconds after the Big Bang—and how research into these moments continues to revolutionize our understanding of our universe Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history. Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe’s first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it. Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

DOWNLOAD EBOOK →This classic book, long out of print, investigates the experimental determination of one of the fundamental constants of astrophysics and its significance for astronomy. The equations of general relativity include a constant lambda in their solution. If lambda is non-zero and positive, this represents the existence of a phenomenon of cosmical repulsion. In this book Eddington discussed the implications of this for models of the universe. The book offers a unique sidelight upon the history of ideas and Eddington's artistry. His evident enjoyment of writing and exposition shine through, and astrophysicists and historians of science will find that this reissue throws fascinating light on one of Britain's greatest scientists.
