Book Description
This book examines the work of prominent South African geologist Alex Du Toit as a means of understanding the debate around continental drift both in segregation-era South Africa and internationally. It contextualises Du Toit’s work within a particularly formative period of South African science, from the paleoanthropological discoveries that sparked debates about the origins of humankind to Jan Smuts’ own theory of holism. Beyond South African scientific discoveries, the book sets Du Toit’s work against a backdrop of ideological struggles over space, both domestically in terms of segregation and nationalism, as well as internationally as South Africa sought to assert its position within the Commonwealth. These debates were embodied by Du Toit’s work on the theory of continental drift, which put Africa – and South Africa – at the centre geologically and geographically. The author also focuses on the divisions in geology caused by drift theory, tracing the vigorous intellectual debate and dissent indicative of the ideological milieu within which scientific thought is constructed. It traces the history of continental drift from its inception in the nineteenth century and later work of Alfred Wegener, which was both elaborated upon and substantiated by Du Toit. The study further focuses on Du Toit’s research on continental drift in South African and South America, and the geological, fossil and climatological evidence used to bolster this theory.

Book Description
Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.

Book Description
In the early twentieth century, American earth scientists were united in their opposition to the new--and highly radical--notion of continental drift, even going so far as to label the theory "unscientific." Some fifty years later, however, continental drift was heralded as a major scientific breakthrough and today it is accepted as scientific fact. Why did American geologists reject so adamantly an idea that is now considered a cornerstone of the discipline? And why were their European colleagues receptive to it so much earlier? This book, based on extensive archival research on three continents, provides important new answers while giving the first detailed account of the American geological community in the first half of the century. Challenging previous historical work on this episode, Naomi Oreskes shows that continental drift was not rejected for the lack of a causal mechanism, but because it seemed to conflict with the basic standards of practice in American geology. This account provides a compelling look at how scientific ideas are made and unmade.

Book Description
This book documents the impulses that drive Elisabeth Eaves' insatiable hunger for the rush of the unfamiliar. She is both restless vagabond and astute observer as she crisscrosses five continents, chasing the exotic in both culture and romance. She loses herself in the jungles of Papua New Guinea, rekindles old love and new passion in Cairo, and finds an intinerant brotherhood of raucous men in the land Down Under. Like the random possessions she leaves in her wake, from Australia to Yemen, she also leaves behind a string of lovers. But this is about more than just sensual conquest; it is also a journey of self-discovery, in which her pursuit ultimately guides her home - back cover.
