**Shortlisted for the Financial Times and Schroders Business Book of the Year Award**Picked as a Book of the Year by THE TIMES, FINANCIAL TIMES, ECONOMIST and NEW STATESMANA BBC RADIO 4 Book of the Week'A compelling narrative of the human story' TIM MARSHALL, author of Prisoners of Geography'Lively, rich and exciting... full of surprises' PETER FRANKOPAN, author of The Silk Roads_____________Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future.These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.In Material World, Ed Conway travels the globe - from the sweltering depths of the deepest mine in Europe, to spotless silicon chip factories in Taiwan, to the eerie green pools where lithium originates - to uncover a secret world we rarely see. Revealing the true marvel of these substances, he follows the mind-boggling journeys, miraculous processes and little-known companies that turn the raw materials we all need into products of astonishing complexity.As we wrestle with climate change, energy crises and the threat of new global conflict, Conway shows why these substances matter more than ever before, and how the hidden battle to control them will shape our geopolitical future. This is the story of civilisation - our ambitions and glory, innovations and appetites - from a new perspective: literally from the ground up. Read more

'Superb' Sunday Times'Revolutionary' Alice Roberts'Hugely important' Jim Al-Khalili_______________A radical retelling of the history of science that foregrounds the scientists erased from history In this major retelling of the history of science from 1450 to the present day, James Poskett explodes the myth that science began in Europe.The blinkered Western gaze focusing on individual 'genius' - Copernicus, Newton, Darwin, Einstein - was only one part of the story. The reality was an utterly global, non-linear pattern of cross-fertilization, competition, cooperation and outright conflict. Each rupture in history carved fresh channels for global exchange.Here, for the first time, Poskett celebrates how scientists from Africa, America, Asia and the Pacific were integral to this very human story. We meet Graman Kwasi, the African botanist who discovered a new cure for malaria; Hantaro Nagaoka, the Japanese scientist who first described the structure of the atom; and Zhao Zhongyao, the Chinese physicist who discovered antimatter._______________'Remarkable.
