Dawn of Small Worlds: Dwarf Planets, Asteroids, Comets (Astronomers' Universe)
by Michael MoltenbreyThis book gives a detailed introduction to the thousands and thousands of smaller bodies in the solar system. Written for interested laymen, amateur astronomers and students it describes the nature and origin of asteroids, dwarf planets and comets, and gives detailed information about their role in the solar system. The author nicely reviews the history of small-world-exploration and describes past, current and future space craft missions studying small worlds, and presents their results. Readers will learn that small solar system worlds have a dramatically different nature and appearance than the planets. Even though research activity on small worlds has increased in the recent past many of their properties are still in the dark and need further research.
The Dawn of the Deed: The Prehistoric Origins of Sex
by John A. LongWe all know about the birds and the bees, but what about the ancient placoderm fishes and the dinosaurs? The history of sex is as old as life itself--and as complicated and mysterious. And despite centuries of study there is always more to know. In 2008, paleontologist John A. Long and a team of researchers revealed their discovery of a placoderm fish fossil, known as "the mother fish," which at 380 million years old revealed the oldest vertebrate embryo--the earliest known example of internal fertilization. As Long explains, this find led to the reexamination of countless fish fossils and the discovery of previously undetected embryos. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction or sex as we know it--sort of. Inspired by this incredible find, Long began a quest to uncover the paleontological and evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on an entertaining and lively tour through the sex lives of ancient fish and exposes the unusual mating habits of arthropods, tortoises, and even a well-endowed (16. 5 inches!) Argentine Duck. Long discusses these significant discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance and how sexual organs in ancient shark-like fishes actually relate to our own sexual anatomy. The Dawn of the Deed is Long's own story of what it's like to be a part of a discovery that rewrites evolutionary history as well as an absolutely rollicking guide to sex throughout the ages in the animal kingdom. It's natural history with a naughty wink.

Dawn of the Neuron: The Early Struggles to Trace the Origin of Nervous Systems
by Michel AnctilIn science, sometimes it is best to keep things simple. <P><P>Initially discrediting the discovery of neurons in jellyfish, mid-nineteenth-century scientists grouped jellyfish, comb-jellies, hydra, and sea anemones together under one term - "coelenterates" - and deemed these animals too similar to plants to warrant a nervous system. In Dawn of the Neuron, Michel Anctil shows how Darwin's theory of evolution completely eradicated this idea and cleared the way for the modern study of the neuron. Once zoologists accepted the notion that varying levels of animal complexity could evolve, they began to use simple-structured creatures such as coelenterates and sponges to understand the building blocks of more complicated nervous systems. Dawn of the Neuron provides fascinating insights into the labours and lives of scientists who studied coelenterate nervous systems over several generations, and who approached the puzzling origin of the first nerve cells through the process outlined in evolutionary theory. Anctil also reveals how these scientists, who were willing to embrace improved and paradigm-changing scientific methods, still revealed their cultural backgrounds, their societal biases, and their attachments to schools of thought and academic traditions while presenting their ground-breaking work. Their attitudes toward the neuron doctrine - where neurons are individual, self-contained cells - proved decisive in the exploration of how neurons first emerged. Featuring photographs and historical sketches to illustrate this quest for knowledge, Dawn of the Neuron is a remarkably in-depth exploration of the link between Darwin's theory of evolution and pioneering studies and understandings of the first evolved nervous systems

Dawn of the New Everything: Encounters with Reality and Virtual Reality
by Jaron LanierNamed one of the best books of 2017 by The Economist, The Wall Street Journal, & VoxThe father of virtual reality explains its dazzling possibilities by reflecting on his own lifelong relationship with technologyBridging the gap between tech mania and the experience of being inside the human body, Dawn of the New Everything is a look at what it means to be human at a moment of unprecedented technological possibility. Through a fascinating look back over his life in technology, Jaron Lanier, an interdisciplinary scientist and father of the term “virtual reality,” exposes VR’s ability to illuminate and amplify our understanding of our species, and gives readers a new perspective on how the brain and body connect to the world. An inventive blend of autobiography, science writing, philosophy and advice, this book tells the wild story of his personal and professional life as a scientist, from his childhood in the UFO territory of New Mexico, to the loss of his mother, the founding of the first start-up, and finally becoming a world-renowned technological guru.Understanding virtual reality as being both a scientific and cultural adventure, Lanier demonstrates it to be a humanistic setting for technology. While his previous books offered a more critical view of social media and other manifestations of technology, in this book he argues that virtual reality can actually make our lives richer and fuller.

The Day Laborers of Science. Technical Work at the Astronomical Observatory of Chile (SpringerBriefs in History of Science and Technology)
by Carlos Sanhueza-CerdaThis book fills a significant gap in the historiography of science by examining the overlooked contributions of non-astronomical personnel in the early National Astronomical Observatory of Chile. Drawing upon David Edgerton's critique of the bias towards academic scientists in historical narratives, this research delves into the roles of other scientists, technicians, collaborators, and other support staff in shaping scientific endeavors. The book analyzes archival documents and reveals the essential yet often unacknowledged labor involved in routine scientific tasks. By challenging the hierarchical structure of observatory organizations and spotlighting the significance of routine work, the book redefines the production of scientific knowledge beyond the conventional focus on eminent scientists. Emphasizing the importance of failures, conflicts, and controversies, this book unveils the hidden narratives of everyday scientific labor, offering a more comprehensive understanding of the history of astronomy in Chile.

The Day the Universe Changed
by James Lee BurkeIn The Day the Universe Changed, James Burke examines eight periods in history when our view of the world shifted dramatically: in the eleventh century, when extraordinary discoveries were made by Spanish crusaders; in fourteenth-century Florence, where perspective in painting emerged; in the fifteenth century, when the advent of the printing press shook the foundations of an oral society; in the sixteenth century, when gunnery developments triggered the birth of modern science; in the early eighteenth century, when hot English summers brought on the Industrial Revolution; in the battlefield surgery stations of the French revolutionary armies, where people first became statistics; in the nineteenth century, when the discovery of dinosaur fossils led to the theory of evolution; and in the 1820s, when electrical experiments heralded the end of scientific certainty. Based on the popular television documentary series, The Day the Universe Changed is a bestselling history that challenges the reader to decide whether there is absolute knowledge to discover - or whether the universe is "ultimately what we say it is."
