' Every person on earth uses, either directly or indirectly, ten metric tons of minerals each year.' So write Dr R. V. Dietrich & Dr Brian J. Skinner in their new book Gems, Granites, & Gravels. Minerals & mineral products are involved in all aspects of our lives; we depend on them to keep us alive & ensure the continuity of our society. As a consequence, they have been a source of fascination & study throughout human history. In this book, Drs Dietrich & Skinner consider not only the beauty of minerals & rocks, but also their utility & their roles in our everyday well-being. Gems, Granites & Gravels is a valuable introduction to mineralogy & to related specialities such as petrology (the study of rocks), crystallography (the study of crystals), & soil science. Discoveries in these fields are described in a historical context, while the authors explain what minerals & rocks are, how they are distributed around the world, how we depend on them, & where to see the most beautiful specimens of both minerals & rocks. This book will appeal to anyone interested in natural history & curious about rocks & minerals, including rock & mineral collectors, students of geology, & professional geologists. ...

Generation Revolution unravels the complex forces shaping the lives of four young Egyptians caught between tradition & modernity, & what their stories mean for the future of the Middle East. In 2003, Rachel Aspden arrived in Egypt as a 23-year-old trainee journalist. She found a country on the brink of change. The two-thirds of Egypt`s 80 million citizens under the age of 30 were stifled, broken & frustrated, caught between a dictatorship that had nothing to offer them & their autocratic parents` generation, & left clinging to tradition & obedience by a lifetime of fear. In January 2011, the young people`s patience ran out. They thought the revolution that followed would change everything for them. But as violence escalated, the economy collapsed & as the united front against Mubarak shattered into sectarianism, many found themselves wavering, hesitant to discard the old ways. What happens when a revolution unravels? Why is a generation raised on Hollywood movies & global brand names turning to religion? How do you choose between sex & tradition, consumerism & faith? Why would people who once chanted for freedom support a military state? And where will the next generation take the Middle East? Following the stories of four young Egyptians
- Amr the atheist software engineer, Amal the village girl who defied her family & her entire community, Ayman the one-time religious extremist & Ruqayah the would-be teenage martyr
- Generation Revolution unravels the complex forces shaping the lives of young people caught between tradition & modernity, & what their stories mean for the future of the Middle East.

What is the history of human populations? How are cultural traditions maintained & changed over time? Why did people destroy their environments in the past & were they ever conservationists? What led to the emergence of marked social inequalities? These are some of the questions that this text addresses & answers, in an application of neo-Darwinian evolutionary ideas to the human past. Stephen Shennan opens with the study of human behaviour, as acted upon by natural selection, & goes on to demonstrate that the same ideas can be applied to human societies, not just through the genes but through what Richard Dawkins has called memes, units of cultural information which are passed on in our second inheritance system, culture. The book ranges from life history theory to game theory, & from the origins of farming to the collapse of societies. ...

Human (and) nature. Epic journeys to the ends of the earth: Salgado`s opus on our planet in its natural state. On a very fortuitous day in 1970, 26-year-old Sebastiao Salgado held a camera for the first time. When he looked through the viewfinder, he had an epiphany: suddenly life made sense. From that day onward
- though it took years of hard work before he had the experience to earn his living as a photographer
- the camera became his tool for interacting with the world. Salgado, who ”always preferred the chiaroscuro palette of black-&-white images, ” shot very little color in his early career before giving it up completely. Having been raised on a rural farm in Brazil, far from civilization & without television, Salgado possessed a deep love & respect for nature; he was also particularly sensitive to the ways in which human beings are affected by their often devastating socio-economic conditions. Of the myriad works Salgado has produced in his esteemed career, three long-term projects stand out: ” Workers” (1993), documenting the vanishing way of life of manual laborers across the world, ” Migrations” (2000), a tribute to mass migration driven by hunger, natural disasters, environmental degradation & demographic pressure, & this new opus, ” Genesis”, the result of an epic eight-year expedition to rediscover the mountains, deserts & oceans, the animals & peoples that have so far escaped the imprint of modern society
- the land & life of a still-pristine planet. ” Some 46 per cent of the planet is still as it was in the time of genesis, ” Salgado reminds us. ” We must preserve what exists.” The Genesis project, along with Salgado`s Instituto Terra, are dedicated to showing the beauty of our planet, reversing the damage done to it, & preserving it for the future. Over 32 trips
- traveled by foot, light aircraft, seagoing vessels, canoes, & even balloons, through extreme heat & cold & in sometimes dangerous conditions
- Salgado created a collection of images showing us nature, animals, & indigenous peoples in such shocking & intense beauty as to take one`s breath away. Mastering the monochrome with an extreme deftness to rival the virtuoso Ansel Adams, Salgado brings black & white photography to a new dimension; the tonal variations in his works, the contrasts of light & dark, recall the works of Old Masters such as Rembrandt & Georges de la Tour. On the earth is instilled a glistening, textured fabric so intricate in its weave that even the most finite details seem to extend to infinity. What does one discover in ” Genesis”? The ancient animal species & volcanoes of the Galapagos; penguins, sea lions, cormorants, & whales of the Antarctic & South Atlantic; Brazilian alligators & jaguars; African lions, leopards, & elephants; the isolated Zo`e tribe deep in the Amazon jungle; the Stone Age Kurowai people of West Papua; nimadic Dinka cattle farmers in Sudan; Nenet nomads & their reindeer herds in the Arctic Circle; Mentawai jungle communities on islands west of Sumatra; the icebergs of the Antarctic; the volcanoes of Central Africa & the Kamchatka Peninsula; Saharan deserts; the Negro & Jurua rivers in the Amazon; the ravines of the Grand Canyon; the glaciers of Alaska...and beyond. Having gone, quite literally in some cases, where no man has gone before, & having spent so much time, energy, & passion dedicated to the making of this work, Salgado likens ” Genesis” to ”my love letter to the planet.”
