Book Description
Where were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos? This book argues that at least some of them must have been produced in the cosmos, and that the fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. The book discusses several models that purport to explain the handedness, ultimately proposing a new explanation that involves cosmic processing of the amino acids produced in space. The book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce.

Book Description
The Gribbins relate the developments in 20th-century astronomy that have led to the shattering realization that all life is made of stardust scattered across the universe in great stellar explosions from supernovae. The authors eloquently explain how the physical structure of the universe has produced conditions ideal for life. 22 illustrations.

Book Description
In 1978, Fred Hoyle proposed that interstellar comets carrying several viruses landed on Earth as part of the panspermia hypotheses. With respect to life, the origin of homochirality on Earth has been the greatest mystery because life cannot exist without molecular asymmetry. Many scientists have proposed several possible hypotheses to answer this long-standing L-D question. Previously, Martin Gardner raised the question about mirror symmetry and broken mirror symmetry in terms of the homochirality question in his monographs (1964 and 1990). Possible scenarios for the L-D issue can be categorized into (i) Earth and exoterrestrial origins, (ii) by-chance and necessity mechanisms, and (iii) mirror-symmetrical and non-mirror-symmetrical forces as physical and chemical origins. These scenarios should involve further great amplification mechanisms, enabling a pure L- or D-world.

Book Description
Following the success of the first edition, this fully updated and revised book continues to provide an interdisciplinary introduction to sustainability issues in the context of chemistry and chemical technology. Its prime objective is to equip young chemists (and others) to more fully to appreciate, defend and promote the role that chemistry and its practitioners play in moving towards a society better able to control, manage and ameliorate its impact on the ecosphere. To do this, it is necessary to set the ideas, concepts, achievements and challenges of chemistry and its application in the context of its environmental impact, past, present and future, and of the changes needed to bring about a more sustainable yet equitable world. Progress since 2010 is reflected by the inclusion of the latest research and thinking, selected and discussed to put the advances concisely in a much wider setting – historic, scientific, technological, intellectual and societal. The treatment also examines the complexities and additional challenges arising from public and media attitudes to science and technology and associated controversies and from the difficulties in reconciling environmental protection and global development. While the book stresses the central importance of rigour in the collection and treatment of evidence and reason in decision-making, to ensure that it meets the needs of an extensive community of students, it is broad in scope, rather than deep. It is, therefore, appropriate for a wide audience, including all practising scientists and technologists.

Book Description
'Superb ... Gribbin has done it again ... the story of how the matter that makes up our bodies travelled from the stars ... a wonderful account' Sunday Times, Books of the Year Every one of us is made of stardust, John Gribbin explains in this dazzling book. Everything we see, touch, breathe and smell, nearly every molecule in our bodies, is the by-product of stars as they live and die in spectacular explosions, scattering material across the universe which is recycled to become part of us. It is only by understanding how stars are made and how they die that we can every understand how we came into being. Taking us on an enthralling journey, John Gribbin shows us the scientific breakthroughs in the quest for our origins. With the raw materials for creating life all around us, he concludes, it is impossible to believe we are alone in the universe. 'An incredible story ... gives a sense of the almost unbelievable coincidence of physical laws and circumstances that resulted in your being able to read these words today' Literary Review 'Gribbin skilfully and engagingly traces the historical sequence ... rather like Sherlock Holmes reading clues' New Scientist

Book Description
The Routledge Companion to Big History guides readers though the variety of themes and concepts that structure contemporary scholarship in the field of big history. The volume is divided into five parts, each representing current and evolving areas of interest to the community, including big history’s relationship to science, social science, the humanities, and the future, as well as teaching big history and ‘little big histories’. Considering an ever-expanding range of theoretical, pedagogical and research topics, the book addresses such questions as what is the relationship between big history and scientific research, how are big historians working with philosophers and religious thinkers to help construct ‘meaning’, how are leading theoreticians making sense of big history and its relationship to other creation narratives and paradigms, what is ‘little big history’, and how does big history impact on thinking about the future? The book highlights the place of big history in historiographical traditions and the ways in which it can be used in education and public discourse across disciplines and at all levels. A timely collection with contributions from leading proponents in the field, it is the ideal guide for those wanting to engage with the theories and concepts behind big history.

Book Description
How did life originate on Earth? For over 50 years, scientists believed that life was the result of a chemical reaction involving simple molecules such as methane and ammonia cooking in a primordial soup. Recent space observations have revealed that old stars are capable of making very complex organic compounds. At some point in their evolution, stars eject those organics and spread them all over the Milky Way galaxy. There is evidence that these organic dust particles actually reached the early Solar System. Through bombardments by comets and asteroids, the young Earth inherited significant amounts of stardust. Was the development of life assisted by the arrival of these extraterrestrial materials? In this book, the author describes stunning discoveries in astronomy and solar system science made over the last 10 years that have yielded a new perspective on the origin of life. Other interesting topics discussed in this book The discovery of diamonds and other gemstones in space The origin of oil Neon signs and fluorescent lights in space Smoke from the stars Stardust in our hands Where oceans come from The possibility of bacteria in space

Book Description
Living with the Stars tells the fascinating story of what truly makes the human body. The body that is with us all our lives is always changing. We are quite literally not who we were years, weeks, or even days ago: our cells die and are replaced by new ones at an astonishing pace. The entire body continually rebuilds itself, time and again, using the food and water that flow through us as fuel and as construction material. What persists over time is not fixed but merely a pattern in flux. We rebuild using elements captured from our surroundings, and are thereby connected to animals and plants around us, and to the bacteria within us that help digest them, and to geological processes such as continental drift and volcanism here on Earth. We are also intimately linked to the Sun's nuclear furnace and to the solar wind, to collisions with asteroids and to the cycles of the birth of stars and their deaths in cataclysmic supernovae, and ultimately to the beginning of the universe. Our bodies are made of the burned out embers of stars that were released into the galaxy in massive explosions billions of years ago, mixed with atoms that formed only recently as ultrafast rays slammed into Earth's atmosphere. All of that is not just remote history but part of us now: our human body is inseparable from nature all around us and intertwined with the history of the universe.
