Stardust Supernovae And The Molecules Of Life

Download or read book Stardust, Supernovae and the Molecules of Life written by Richard Boyd and published by Springer Science & Business Media. This book was released on 2011-12-15 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Download or read book Possible Scenarios for Homochirality on Earth written by Michiya Fujiki and published by Buy this from MDPI Books. This book was released on 2019-11-14 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Chemistry for Sustainable Technologies written by Neil Winterton and published by Royal Society of Chemistry. This book was released on 2021-02-04 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020-07-07 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Erik Olin Wright, one of the most important sociologists of his time, takes readers along on his intimate and brave journey toward death, and asks the big questions about human mortality. From the renowned Marxist sociologist and educator Erik Olin Wright, Stardust to Stardust is a curated collection of writings from the months of his treatment and hospitalization for acute myeloid leukemia. This combination of personal narrative with Wright’s analytical perspective results in a deeply complex, philosophical meditation on death and the meaning of existence.
