Guth’s startling theory—widely regarded as one of the most important contributions to science during the twentieth century—states that the big bang was set into motion by a period of hyper-rapid “inflation,” lasting only a billion-trillion-billionth of a second. The Inflationary Universe is the passionate story of one leading scientist’s effort to look behind the cosmic veil and explain how the universe began.

    Among the estimated one hundred billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of becoming in each case. Since Newton, we have turned to physics to assess reality. Butphysics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere.Building on concepts from his work as a complex systems researcher at the Santa Fe Institute, Kauffman focuses in particular on the idea of cells constructing themselves and introduces concepts such as constraint closure. Living systems are defined by the concept of organization which has notbeen focused on in enough in previous works. Cells are autopoetic systems that build themselves: they literally construct their own constraints on the release of energy into a few degrees of freedom that constitutes the very thermodynamic work by which they build their own self creating constraints.Living cells are machines that construct and assemble their own working parts. The emergence of such systems-the origin of life problem-was probably a spontaneous phase transition to self-reproduction in complex enough prebiotic systems. The resulting protocells were capable of Darwin's heritablevariation, hence open-ended evolution by natural selection. Evolution propagates this burgeoning organization. Evolving living creatures, by existing, create new niches into which yet further new creatures can emerge. If life is abundant in the universe, this self-constructing, propagating, exploding diversity takes us beyond physics to biospheres everywhere.

    To understand the universe in the far future, we must first describe its present state and structure on the grand scale, and how its present properties arose. Dr Islam explains these topics in an accessible way in the first part of the book. From this background he speculates about the future evolution of the universe and predicts the major changes that will occur. The author has largely avoided mathematical formalism and therefore the book is well suited to general readers with a modest background knowledge of physics and astronomy.

    Amir Aczel, critically acclaimed author of Fermat's Last Theorem, takes us into the heart of science's greatest mystery. In January 1998, astronomers found evidence that the cosmos is expanding at an ever-increasing rate. The way we perceive the universe was changed forever. The most compelling theory cosmologists could find to explain this phenomenon was Einstein's cosmological constant, a theory he conceived--and rejected---over eighty years ago. Drawing on newly discovered letters of Einstein--many translated here for the first time--years of research, and interviews with prominent mathematicians, cosmologists, physicists, and astronomers, Aczel takes us on a fascinating journey into "the strange geometry of space-time," and into the mind of a genius. Here the unthinkable becomes real: an infinite, ever-expanding, ever-accelerating universe whose only absolute is the speed of light. Awesome in scope, thrilling in detail, God's Equation is storytelling at its finest.

    They infinitely warp space and time, allowing nothing to escape: not matter, not even light. They are stellar corpses that have crushed themselves into oblivion, seemingly suspending the traditional laws of physics. The Big bang may have peppered the universe with primordial black holes, as small as protons but as massive as mountains. The universe itself may be disappearing into the final black hole. Black holes (BHs) and their warping effect on spacetime are described, beginning with a discussion on stellar evolution that includes white dwarfs, supernovas and neutron stars. The structure of static, rotating, and electrically charged BHs are considered, as well as the general theory of relativity, quantum mechanics, the Einstein-Rosen bridge, and wormholes in spacetime. Attention is also given to gravitational lenses, various space geometries, quasars, Seyfert galaxies, supermassive black holes, the evaporation and particle emission of BHs, and primordial BHs, including their temperature and lifetime. The author's engrossing, non-technical explanations are enhanced by numerous illustrations.

    Newborn babies typically wake every two to three hours, and there’s nothing bleary-eyed, exhausted parents want more than a night of uninterrupted sleep. But while there’s plenty of advice out there, there is nothing that’s based on the latest cutting-edge research about sleep—until now. In How Babies Sleep, Sofia Axelrod, PhD—neuroscientist, sleep consultant, and mother of two—introduces the first baby sleep method that is truly rooted in the science of sleep. After having her first child, Axelrod realized that the typical baby sleep advice conflicted with the actual science of sleep, inlcuding the findings from her mentor’s Nobel Prize–winning sleep lab. She developed her transformative method based on the latest discoveries about our body’s circadian clock and how it is disturbed by light and other external stimuli. After seeing incredible results with her own babies, she has since counseled countless families in her groundbreaking method—which works with babies’ needs and helps little ones learn to self-soothe, fall asleep more easily, and stay asleep through the night. You’ll discover helpful tips that work, and learn: why using a red lightbulb (instead of a regular one) in the nursery at night can minimize wakings; why the age-old advice “don’t wake a sleeping baby” isn’t true; how to create a healthy routine; how to sleep train gently with minimal crying (under two minutes); and so much more in this revolutionary and effective book that will help both you and your baby enjoy a peaceful night’s sleep.

    A realistic guide to becoming an Astronaut at a young age.

    But more than that, as Doug Macdougall makes clear, the science also provides important clues to the future of the planet. In an entertaining and accessibly written narrative, Macdougall gives an overview of Earth’s astonishing history based on information extracted from rocks, ice cores, and other natural archives. He explores such questions as: What is the risk of an asteroid striking Earth? Why does the temperature of the ocean millions of years ago matter today? How are efforts to predict earthquakes progressing? Macdougall also explains the legacy of greenhouse gases from Earth’s past and shows how that legacy shapes our understanding of today’s human-caused climate change. We find that geoscience in fact illuminates many of today’s most pressing issues—the availability of energy, access to fresh water, sustainable agriculture, maintaining biodiversity—and we discover how, by applying new technologies and ideas, we can use it to prepare for the future.
