Attraverso la loro scrittura, esplorano idee profonde come l'infinito e la natura dei numeri, rendendoli accessibili e coinvolgenti. Il loro approccio rivela la bellezza intrinseca e l'interconnessione della matematica nel nostro mondo.






American science produces the best medical treatments in the world. Yet U.S. citizens lag behind in life expectancy and quality of life. Robert Kaplan marshals extensive data to make the case that U.S. health care priorities are sorely misplaced-invested in attacking disease, not in solving social problems that engender disease in the first place.
The US spends more per capita on health care than any other country, yet it ranks last among comparison nations on the major health indicators. Here, Kaplan analyzes what can be done to turn this situation around and provides useful advice to policymakers.
Traces the development of mathematical thinking and describes the characteristics of the "republic of numbers" in terms of humankind's fascination with, and growing knowledge of, infinity.
NAMED ONE OF THE BEST BOOKS OF THE YEAR BY FINANCIAL TIMES From Robert D. Kaplan, named one of the world's Top 100 Global Thinkers by Foreign Policy magazine, comes a penetrating look at the volatile region that will dominate the future of geopolitical conflict. Over the last decade, the center of world power has been quietly shifting from Europe to Asia. With oil reserves of several billion barrels, an estimated nine hundred trillion cubic feet of natural gas, and several centuries' worth of competing territorial claims, the South China Sea in particular is a simmering pot of potential conflict. The underreported military buildup in the area where the Western Pacific meets the Indian Ocean means that it will likely be a hinge point for global war and peace for the foreseeable future. In Asia's Cauldron, Robert D. Kaplan offers up a vivid snapshot of the nations surrounding the South China Sea, the conflicts brewing in the region at the dawn of the twenty-first century, and their implications for global peace and stability. One of the world's most perceptive foreign policy experts, Kaplan interprets America's interests in Asia in the context of an increasingly assertive China. He explains how the region's unique geography fosters the growth of navies but also impedes aggression. And he draws a striking parallel between China's quest for hegemony in the South China Sea and the United States' imperial adventure in the Caribbean more than a century ago. To understand the future of conflict in East Asia, Kaplan argues, one must understand the goals and motivations of its leaders and its people. Part travelogue, part geopolitical primer, Asia's Cauldron takes us on a journey through the region's boom cities and ramshackle slums: from Vietnam, where the superfueled capitalism of the erstwhile colonial capital, Saigon, inspires the geostrategic pretensions of the official seat of government in Hanoi, to Malaysia, where a unique mix of authoritarian Islam and Western-style consumerism creates quite possibly the ultimate postmodern society; and from Singapore, whose benevolent autocracy helped foster an economic miracle, to the Philippines, where a different brand of authoritarianism under Ferdinand Marcos led not to economic growth but to decades of corruption and crime. At a time when every day's news seems to contain some new story--large or small--that directly relates to conflicts over the South China Sea, Asia's Cauldron is an indispensable guide to a corner of the globe that will affect all of our lives for years to come. Praise for Asia's Cauldron Asia's Cauldron is a short book with a powerful thesis, and it stands out for its clarity and good sense. . . . If you are doing business in China, traveling in Southeast Asia or just obsessing about geopolitics, you will want to read it.--The New York Times Book Review Kaplan has established himself as one of our most consequential geopolitical thinkers. . . . [Asia's Cauldron] is part treatise on geopolitics, part travel narrative. Indeed, he writes in the tradition of the great travel writers.-- The Weekly Standard Kaplan's fascinating book is a welcome challenge to the pessimists who see only trouble in China's rise and the hawks who view it as malign.--The Economist Muscular, deeply knowledgeable . . . Kaplan is an ultra-realist [who] takes a non-moralistic stance on questions of power and diplomacy.--Financial Times From the Hardcover edition.
"Robert Kaplan first visited Romania in the 1970s, when he was a young journalist and the country was a bleak Communist backwater. It was one of the darkest corners of Europe, but few Westerners were paying attention. What ensued was a lifelong obsession with a critical, often overlooked country--a country that, today, is key to understanding the current threat that Russia poses to Europe. In Europe's Shadow is a vivid blend of memoir, travelogue, journalism, and history, a masterly work thirty years in the making--the story of a journalist coming of age, and a country struggling to do the same. Through the lens of one country, Kaplan examines larger questions of geography, imperialism, the role of fate in international relations, the Cold War, the Holocaust, and more."--publisher
Kaplan describes a specific and actionable roadmap for helping readers define their own success and reach their unique potential. This effort requires several key steps in an integrated process, as well as a high level of motivation and hard work.
The 'invention' of zero made arithmetic infinitely easier - try doing division in Roman numerals - and it now forms part of the binary code which powers all our computers. Robert Kaplan traces 'the nothing that is' back to its origins as two wedges pressed into a wet lump of Sumerian clay. He explores the contributions of Greeks, Mayans, Hindus and humanists, and shows how zero opened the door to the strange complexities of irrational, infinitesimal and imaginary numbers. 'If you look at zero,' he writes, 'you see nothing; but look through it and you will see the world.'
The insights, discoveries and theories of great geographers and geopolitical thinkers of the past look back at critical pivotal events in history and then look forward at the evolving global scene
