"A biography of ancient Greek mathematician Eratosthenes, who used geometry to calculate the circumference of the earth. He is also known as the Father of Geography"--Provided by publisher.

Describes the early 18th-century expedition of scientists sent by France and Spain to colonial Peru to measure the degree of equatorial latitude, which could resolve the debate between whether the earth was spherical or flattened at the poles.

During geologic spans of time, Earth's shifting tectonic plates, atmosphere, freezing water, thawing ice, flowing rivers, and evolving life have shaped Earth's surface features. The resulting hills, mountains, valleys, and plains shelter ecosystems that interact with all life and provide a record of Earth surface processes that extend back through Earth's history. Despite rapidly growing scientific knowledge of Earth surface interactions, and the increasing availability of new monitoring technologies, there is still little understanding of how these processes generate and degrade landscapes. Landscapes on the Edge identifies nine grand challenges in this emerging field of study and proposes four high-priority research initiatives. The book poses questions about how our planet's past can tell us about its future, how landscapes record climate and tectonics, and how Earth surface science can contribute to developing a sustainable living surface for future generations.

For readers of Homegoing and The Leavers, a compelling and profound debut novel about a Tibetan family's journey through exile. International Bestseller Longlisted for the Center for Fiction First Novel Prize Shortlisted for the Scotiabank Giller Prize In the wake of China's invasion of Tibet throughout the 1950s, Lhamo and her younger sister, Tenkyi, arrive at a refugee camp in Nepal. They survived the dangerous journey across the Himalayas, but their parents did not. As Lhamo-haunted by the loss of her homeland and her mother, a village oracle-tries to rebuild a life amid a shattered community, hope arrives in the form of a young man named Samphel and his uncle, who brings with him the ancient statue of the Nameless Saint-a relic known to vanish and reappear in times of need. Decades later, the sisters are separated, and Tenkyi is living with Lhamo's daughter, Dolma, in Toronto. While Tenkyi works as a cleaner and struggles with traumatic memories, Dolma vies for a place as a scholar of Tibetan Studies. But when Dolma comes across the Nameless Saint in a collector's vault, she must decide what she is willing to do for her community, even if it means risking her dreams. Breathtaking in its scope and powerful in its intimacy, We Measure the Earth with Our Bodies is a gorgeously written meditation on colonization, displacement, and the lengths we'll go to remain connected to our families and ancestral lands. Told through the lives of four people over fifty years, this novel provides a nuanced, moving portrait of the little-known world of Tibetan exiles.

Long trackways, stone rows, circles, standing stones, and huge earthworks may be found all over Britain, monuments dating back well over 4000 years. The authors have made a remarkable breakthrough in understanding the system by which prehistoric monuments were designed and placed.

Recounts the mathematical reasoning which was used to calculate first the size of the earth, then the solar system, and so on up to the universe.

Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. - Coverage of measurement, mapping and profiling techniques - Descriptions of technologies for remote measurement of ocean currents and their signatures - Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change
