Among the rarest things on earth, meteorites carry an air of mystery and drama while having left a pervasive, outsized mark on our planet and civilization. In Meteorite, Maria Golia tells the long history of our engagement with these sky-born space rocks. Arriving amid thunderous blasts and flame-streaked skies, meteorites were once thought to be messengers from the gods. Worshipped in the past, now scrutinized with equal zeal by scientists, meteorites helped sculpt Earth’s features and have shaped our understanding of the planet’s origins. Prized for their outlandish qualities, meteorites are a collectible and a commodity, objects of art and artists’ desires and a literary muse; and ‘meteorite hunting’ is an adventurous, lucrative profession for some and an addictive hobby for thousands of others. A richly illustrated, remarkably wide-ranging account of the culture and science surrounding meteorites, Golia’s book explores the ancient, lasting power of the meteorite to inspire and awe.

This book relates the history of asteroid discoveries and christenings, from those of the early pioneering giants of Hersehel and Piazzi to modern-day amateurs. Moving from history and anecdotal information to science, the book's structure is provided by the names of the asteroids, including one named after the author. Free from a need to conform to scientific naming conventions, the names evidence hero-worship, sycophancy, avarice, vanity, whimsy, erudition and wit, revealing the human side of astronomers, especially where controversy has followed the christening. Murdin draws from extensive historical records to explore the debate over these names. Each age reveals its own biases and preferences in the naming process. “/p> Originally regarded as “vermin of the skies,” asteroids are minor planets, rocky scraps left over from the formation of the larger planets, or broken fragments of worlds that have collided. Their scientific classification as “minor” planets makes them seem unimportant, but over the past decades asteroids have been acknowledged to be key players in the Solar System. This view of their starring role even alters the trajectories of spacecraft: NASA’s policy for new space missions en route to the outer planets is that they must divert to study passing asteroids whenever possible. This book provides for readers a complete tour of the fascinating world of asteroids.

An engaging exploration with renowned astronomer Paul Murdin of how life emerged on Earth—and the possibilities that it exists elsewhere There is no more fascinating question than whether or not we are alone in a vast universe. Here, Paul Murdin applies the latest scientific discoveries and theories to inquire whether life exists on other planets and, if so, what forms it might take. Could there be somewhere life as advanced as here on Earth, or are we more likely to find primitive life-forms? Or are we the sole living organisms in a desolate and boundless cosmos? Professor Murdin invites us to join him in exploring an extraordinary array of evidence to determine if there is life elsewhere in the cosmos. He examines the case for life on Mars and Europa and asks whether on Enceladus or Titan we might find the “warm little” pond that Darwin speculated was where life began here on Earth. Describing the cosmic habitats that produce the alien worlds of our solar system and others, he examines the chances of finding life and the prospects for successful communication with an extraterrestrial intelligence.

To understand climate change today, we first need to know how Earth’s climate changed over the past 450 million years. Finding answers depends upon contributions from a wide range of sciences, not just the rock record uncovered by geologists. In Earth’s Climate Evolution, Colin Summerhayes analyzes reports and records of past climate change dating back to the late 18th century to uncover key patterns in the climate system. The book will transform debate and set the agenda for the next generation of thought about future climate change. The book takes a unique approach to the subject providing a description of the greenhouse and icehouse worlds of the past 450 million years since land plants emerged, ignoring major earlier glaciations like that of Snowball Earth, which occurred around 600 million years ago in a world free of land plants. It describes the evolution of thinking in palaeoclimatology and introduces the main players in the field and how their ideas were received and, in many cases, subsequently modified. It records the arguments and discussions about the merits of different ideas along the way. It also includes several notes made from the author’s own personal involvement in palaeoclimatological and palaeoceanographic studies, and from his experience of working alongside several of the major players in these fields in recent years. This book will be an invaluable reference for both undergraduate and postgraduate students taking courses in related fields and will also be of interest to historians of science and/or geology, climatology and oceanography. It should also be of interest to the wider scientific and engineering community, high school science students, policy makers, and environmental NGOs. Reviews: "Outstanding in its presentation of the facts and a good read in the way that it intersperses the climate story with the author's own experiences. [This book] puts the climate story into a compelling geological history." -Dr. James Baker "The book is written in very clear and concise prose, [and takes] original, enlightening, and engaging approach to talking about 'ideas' from the perspective of the scientists who promoted them." -Professor Christopher R. Scotese "A thrilling ride through continental drift and its consequences." - Professor Gerald R. North "Written in a style and language which can be easily understood by laymen as well as scientists." - Professor Dr Jörn Thiede "What makes this book particularly distinctive is how well it builds in the narrative of change in ideas over time." - Holocene book reviews, May 2016 "This is a fascinating book and the author’s biographical approach gives it great human appeal." - E Adlard

From one of the world’s leading natural scientists and the acclaimed author of Trilobite!, Life: A Natural History of Four Billion Years of Life on Earth and Dry Storeroom No. 1 comes a fascinating chronicle of life’s history told not through the fossil record but through the stories of organisms that have survived, almost unchanged, throughout time. Evolution, it seems, has not completely obliterated its tracks as more advanced organisms have evolved; the history of life on earth is far older—and odder—than many of us realize. Scattered across the globe, these remarkable plants and animals continue to mark seminal events in geological time. From a moonlit beach in Delaware, where the hardy horseshoe crab shuffles its way to a frenzy of mass mating just as it did 450 million years ago, to the dense rainforests of New Zealand, where the elusive, unprepossessing velvet worm has burrowed deep into rotting timber since before the breakup of the ancient supercontinent, to a stretch of Australian coastline with stromatolite formations that bear witness to the Precambrian dawn, the existence of these survivors offers us a tantalizing glimpse of pivotal points in evolutionary history. These are not “living fossils” but rather a handful of tenacious creatures of days long gone. Written in buoyant, sparkling prose, Horseshoe Crabs and Velvet Worms is a marvelously captivating exploration of the world’s old-timers combining the very best of science writing with an explorer’s sense of adventure and wonder.

Life on our planet depends upon having a climate that changes within narrow limits – not too hot for the oceans to boil away nor too cold for the planet to freeze over. Over the past billion years Earth’s average temperature has stayed close to 14-15°C, oscillating between warm greenhouse states and cold icehouse states. We live with variation, but a variation with limits. Paleoclimatology is the science of understanding and explaining those variations, those limits, and the forces that control them. Without that understanding we will not be able to foresee future change accurately as our population grows. Our impact on the planet is now equal to a geological force, such that many geologists now see us as living in a new geological era – the Anthropocene. Paleoclimatology describes Earth’s passage through the greenhouse and icehouse worlds of the past 800 million years, including the glaciations of Snowball Earth in a world that was then free of land plants. It describes the operation of the Earth’s thermostat, which keeps the planet fit for life, and its control by interactions between greenhouse gases, land plants, chemical weathering, continental motions, volcanic activity, orbital change and solar variability. It explains how we arrived at our current understanding of the climate system, by reviewing the contributions of scientists since the mid-1700s, showing how their ideas were modified as science progressed. And it includes reflections based on the author’s involvement in palaeoclimatic research. The book will transform debate and set the agenda for the next generation of thought about future climate change. It will be an invaluable course reference for undergraduate and postgraduate students in geology, climatology, oceanography and the history of science.

"Astonishing new research suggests that 470 million years ago, a stupendous collision in the Asteroid Belt (whose debris is still falling today) bombarded the Earth with meteorites of all sizes. A revolutionary idea is emerging that the resulting ecological disturbance may have been responsible for the single greatest increase in biological diversity since the origin of complex life - the hitherto unexplained Great Ordovician Biodiversity Event. Introducing these fresh discoveries to a wider public for the first time, Ted Nield challenges the orthodox view that meteorite strikes are always bad news for life on Earth. He argues that one of the most widely known scientific theories - that dinosaurs were wiped out by a strike 65 million years ago - isn't the whole picture, and that the causes of the end-Cretaceous mass extinction (of which the dinosaurs' demise was a part) were much more varied and complex. Meteorites have been the stuff of legend throughout human history, interpreted as omens of doom or objects of power. But only in the 18th century, when the study of falling space debris became a science, were meteorites used to unlock the mysteries of our universe. Incoming! traces the history of meteorites from the first recorded strike to the video recordings made routinely today, showing how our interpretations have varied according to the age in which they fell, and how meteorite impacts were given fresh urgency with the advent of the atom bomb. Introducing a wealth of fascinating characters alongside extraordinary new research, Ted Nield has written the perfect introduction to the science and history of the falling sky"--Jacket.

This title brings together work on embodiment, action, and the predictive mind. At the core is the vision of human minds as prediction machines - devices that constantly try to stay one step ahead of the breaking waves of sensory stimulation, by actively predicting the incoming flow. In every situation we encounter, that complex prediction machinery is already buzzing, proactively trying to anticipate the sensory barrage. The book shows in detail how this strange but potent strategy of self-anticipation ushers perception, understanding, and imagination simultaneously onto the cognitive stage.
