The book summarizes the results of the experimental studies of phase relations in the chemical systems relevant to Earth, carried out by the author in a time period of over 20 years between 1979 and 2001. It is based on 1000 piston-cylinder experiments at pressures up to 4 GPa, and close to 700 experiments carried out with a multi-anvil apparatus at pressures up to 24 GPA. This is the largest published collection of calculated phase diagrams for the chemical systems relevant to Earth. This is also the first time that the phase relations at the relatively low pressures of the lithospheric mantle, mainly applicable to the experimental thermobarometry of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the phase relations of the sublithospheric upper mantle and the uppermost lower mantle, primarily applicable to inclusions in diamond and schocked meteorites. "Tibor Gasparik has devoted his career to determining the high-pressure, high-temperature phase relations of the geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon (NCMAS) oxide system. This book is his opus magnum, summarizing more than 1700 experiments in over 120 figures. ... I have found Phase Diagrams for Geoscientists to be a useful first port-of-call for finding the P-T stability fields ... and I can recommend the book as a reference for geoscientists requiring an overview of the stable phase assemblages in the top 700 km of the Earth."

On July 21, 1969, the first man set foot on The Moon. When Neil Armstrong was asked if this made him feel big, he answered: "No, it made me feel really, really small." 50 years later, this publication celebrates that special moment that put life on earth into a totally different perspective. It collects pictures of the world's best photographers from the 1840s until today. Next to historical photographs and imagery printed in media, the publication features many artists that each in their own way reflect on this mystical celestial body, we call 'moon'. The book shows the diversity of meanings of The Moon, it's relation to mankind and to nature. The Moon has always both attracted and scared people around the world. It is our everyday connection to the unfathomable universe. Since time immemorial it is revered for its beauty, its stillness and mysterious appearance and yet also feared for its supernatural-seeming qualities. In mythology The Moon has always been given a central place. With its magnetic forces it changes the tides and has a direct and uncontrollable impact on mankind from above. In 1840, barely three years after the invention of photography, J.W. Draper makes the first picture ever made of The Moon and since that day photographers have never stopped following his example. The paradoxical aspects of the moon continue to fascinate and inspire. Like a photograph The Moon depends on sunlight to be visible. It has no light of its own and no apparent strength to resist our nightly city lights either. Photographers feel this close connection to The Moon's characteristics and find the perfect object in its aesthetics. The landing on The Moon was a culmination point of the1960's Space Race between the United States and the Soviet Union, which quickly became a symbol of the Cold War. The images of the landing became the bearer of values and symbols of the United States and were widely spread through various media. In 1973 NASA abolished its moon program. The Moon had been conquered and the public seemed to have had lost interest. However, today people still find The Moon fascinating, and humanity continues to dream about setting foot on the sun's shadow.

Moons: A Very Short Introduction (Paperback): David A. Rothery Moons: A Very Short Introduction (Paperback)
David A. Rothery
R255 Discovery Miles 2 550 Ships in 10 - 15 working days

Proving to be both varied and fascinating, moons are far more common than planets in our Solar System. Our own Moon has had a profound influence on Earth, not only through tidal effects, but even on the behaviour of some marine animals. Many remarkable things have been discovered about the moons of the giant outer planets from Voyager, Galileo, Cassini, and other spacecraft. Scientists have glimpsed volcanic activity on Io, found oceans of water on Titan, and captured photos of icy geysers bursting from Enceladus. It looks likely that microbial life beyond the Earth may be discovered on a moon rather than a planet. In this Very Short Introduction David Rothery introduces the reader to the moons of our Solar System, beginning with the early discoveries of Galileo and others, describing their variety of mostly mythological names, and the early use of Jupiter's moons to establish position at sea and to estimate the speed of light. Rothery discusses the structure, formation, and influence of our Moon, and those of the other planets, and ends with the recent discovery of moons orbiting asteroids, whilst looking forward to the possibility of finding moons of exoplanets in planetary systems far beyond our own. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

R3,946 Discovery Miles 39 460 Ships in 10 - 15 working days

Seismology is a highly effective tool for investigating the internal structure of the Earth. Similar techniques have also successfully been used to study other planetary bodies (planetary seismology), the Sun (helioseismology), and other stars (asteroseismology). Despite obvious differences between stars and planetary bodies, these disciplines share many similarities and together form a coherent field of scientific research. This unique book takes a transdisciplinary approach to seismology and seismic imaging, reviewing the most recent developments in these extraterrestrial contexts. With contributions from leading scientists, this timely volume systematically outlines the techniques used in observation, data processing, and modelling for asteroseismology, helioseismology, and planetary seismology, drawing comparisons with seismic methods used in geophysics. Important recent discoveries in each discipline are presented. With an emphasis on transcending the traditional boundaries of astronomy, solar, planetary and Earth sciences, this novel book is an invaluable resource and reference for undergraduates, postgraduates and academics.

DOI: 10. 1007/s11214-008-9450-0 (c) Springer Science+Business Media B. V. 2008 Exploration is mankind's imperative. Since the beginnings of civilization, men and women have not been content to build a wall around their settlements and stay within its con nes. They explored the land around them, climbed the mountains, and scanned the horizons. The boldest among them pushed exploration to the most distant frontiers of the planet. As a result, much of the Earth was inhabited well before the days of the renowned European - th th plorers of the 15 and 16 centuries. Exploration did not cease, after the circumnavigation of the globe; it continued to the present. Today explorers are going in new directions, not just east and west, north and south. They explore backward in time and upward in space. Arc- ology explores the shorter time scales, and geochemistry the longer time scales of geophy- cal events: asteroidal and cometary collisions, magnetic reversals, continental formation and more. However, on Earth we cannot go back inde nitely, for much of the evidence of the very earliest days has been lost.

"What if?" questions have always stimulated people to think in new ways. "What if the Earth Had Two Moons "leads us on a fascinating 10 world journey exploring what the Earth would be like if conditions in the universe were slightly different. The answer: Earth would be different, often in ways that would surprise us. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but not forever. Eventually the moons collide, with one more-massive moon emerging after a period during which Earth has a Saturn-like ring. The scenarios also shed new light on the burgeoning search for life on planets orbiting other stars.

Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, "What if the Moon Didn't Exist?, "with completely new scenarios backed by the latest astronomical research.

An entertaining, often surprising cultural examination of Earth's moon, through history, science, and literature, from ancient times to the present Werewolves and Wernher von Braun, Stonehenge and the sex lives of sea corals, aboriginal myths, and an Anglican bishop: In his new book, Moon, Bernd Brunner weaves variegated information into an enchanting glimpse of Earth's closest celestial neighbor, whose mere presence inspires us to wonder what might be "out there." Going beyond the discoveries of contemporary science, Brunner presents an unusual cultural assessment of our complex relationship with Earth's lifeless, rocky satellite. As well as offering an engaging perspective on such age-old questions as "What would Earth be like without the moon?" Brunner surveys the moon's mythical and religious significance and provokes existential soul-searching through a lunar lens, inquiring, "Forty years ago, the first man put his footprint on the moon. Will we continue to use it as the screen onto which we cast our hopes and fears?" Drawing on materials from different cultures and epochs, Brunner walks readers down a moonlit path illuminated by more than seventy-five vintage photographs and illustrations. From scientific discussions of the moon's origins and its "chronobiological" effects on the mating and feeding habits of animals to an illuminating interpretation of Bishop Francis Godwin's 1638 novel The Man in the Moone, Brunner's ingenious and interdisciplinary explorations recast a familiar object in an entirely original and unforgettable light and will change the way we view the nighttime sky.

Ever since the serendipitous discovery of planet Uranus in 1871, astronomers have been hunting for new worlds in the outer regions of our solar system. This exciting and ongoing quest culminated recently in the discovery of hundreds of ice dwarfs in the Kuiper belt, robbed Pluto from its 'planet' status, and led to a better understanding of the origin of the solar system.

This timely book reads like a scientific 'who done it', going from the heights of discovery to the depths of disappointment in the hunt for 'Planet X'. Based on many personal interviews with astronomers, the well-known science writer Govert Schilling introduces the heroes in the race to be the first in finding another world, bigger than Pluto.

Planetary Atmospheres (Paperback): F.W. Taylor Planetary Atmospheres (Paperback)
F.W. Taylor
R1,734 Discovery Miles 17 340 Ships in 10 - 15 working days

The emphasis of Planetary Atmospheres is on comparative aspects of planetary atmospheres, generally meaning comparison with the Earth, including atmospheric composition, thermal structure, cloud properties, dynamics, weather and climate, and aeronomy. The goal is to look for common processes at work under different boundary conditions in order to reach a fundamental understanding of the physics of atmospheres. As part of a general Physics course, the material is chosen to emphasise certain aspects that will be of broad topical interest:
- evolutionary processes, setting the Earth in its context as a planet and a member of the Solar System
- the properties of atmospheres that affect the climate near the surface of each planet
- measurement techniques and models, where the same experimental and theoretical physics is applied under different conditions to investigate and explain atmospheric behaviour.
These might be thought of as the astronomical, environmental, and technical sides of the discipline respectively.
The book covers the basic physics of planetary atmospheres in a single text for students or anyone interested in this area of science. The approach is the same as in the author's previous book Elementary Climate Physics: an overview, followed by more detailed discussion of key topics arranged by physical phenomenon and not planet by planet as usually found in this field. There is an emphasis on acquiring and interpreting measurements, and the basic physics of instruments and models, with key definitions and some historical background in footnotes and in the glossary at the end of the book.

The goal of sending humans to Mars is becoming increasingly technologically feasible, but the prospect of space colonization raises important questions about civilizational ethics and collective morality. History shows how destructive colonialism has been, resulting in centuries-long struggles to achieve liberation from the violent competition for land and resources by colonial powers. Space settlement poses the same temptation on a cosmic scale, with commercial actors and government space agencies doing the work previously carried out by European empires. The question is whether humans will take a different approach in this new frontier.In Sovereign Mars, astrobiologist Jacob Haqq-Misra argues that settling Mars offers humankind a transformative opportunity to avoid the mistakes of the past by "liberating Mars" as a sovereign planet from the start. Rather than see space as a way to escape human problems on Earth, Mars presents humanity with a challenge to address these problems by thinking carefully about the theory and practice of civilization. Drawing on past examples of cooperative sovereignty, such as the Outer Space Treaty of 1967, the United Nations Law of the Sea Conventions, and the Antarctic Treaty System, Haqq-Misra begins a conversation about governance in space well in advance of the first arrival of humans on Mars and makes the case for an analogous approach to space that will preserve the space environment and benefit future generations. Haqq-Misra examines the emergence of sovereignty in space through the lens of historical precedent on Earth and develops models of shared governance that could maximize the transformative potential of Mars settlement. Sovereign Mars proposes the planet would serve humankind best as an independent planetary state, a juridical peer to Earth, to enable new experiments in human civilization and develop a pragmatic model for shared governance on Mars.

R228 Discovery Miles 2 280 Ships in 10 - 15 working days

If you always thought that it was Giovanni Schiaparelli who first coined the phrase 'Canali' pertaining to the straight lines he appeared to observe on Mars you'd be wrong. In 1858, an astronomer working at the Vatican observatory named father Pietro Angelo Secchi took it upon himself to create his own drawings of Mars. The red planet was now nearing a close approach to earth and the powerful Vatican telescope was capable of resolving detail previously invisible to most astronomers. Secchi thought he saw a series of straight lines on the Martian surface so he made an innocuous notation in his notes. His sketches and articles were published in 1859 in which he referred several times to 'Canale Atlantico' or 'Canale Ceruleo'. His regrettable choice of words would not have an impact for another eight years. This volume tells not only of people and places that have influenced mankind's relationship with the enigmatic red planet, but it also shows you the colour drawings that Secchi made, which were provided to us directly by the Vatican itself. Along with many other interesting stories, drawings and photographs this book will be a prize for both the novice or ardent student of Mars.

Tony Hallam
R289 Discovery Miles 2 890 Ships in 10 - 15 working days

This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. The most famous is the mass extinction that happened about 65 million years ago, and that caused the death of the dinosaurs. But that was not the worst mass extinction: that honour goes to the extinction at the end of the Permian Period, about 250 million years ago, when over 90% of life is thought to have become extinct. What caused these catastrophes? Was it the effects of a massive meteorite impact? There is evidence for such an impact about 65 million years ago. Or was it a period of massive volcanic activity? There is evidence in the rocks of huge lava flows at periods that match several of the mass extinctions. Was it something to do with climate change and sea level? Or was it a combination of some or all of these? The question has been haunting geologists for a number of years, and it forms one of the most exciting areas of research in geology today. In this book, Tony Hallam, a distinguished geologist and writer, looks at all the different theories and also what the study of mass extinctions might tell us about the future. If climate change is a key factor, we may well, as some scientists have suggested, be in a period of mass extinction of our own making.
