ABSTRACTSeventeen years ago, Sepha Stephanos fled the Ethiopian revolution after witnessing soldiers beat his father to the point of certain death, selling off his parents' jewelry to pay for passage out of the country. Now he finds himself running a grocery store In a poor African-American neighborhood in Washington, D.C., where his daytime customers are schoolchildren and his nighttime customers are prostitutes and alcoholics. His only companions are two fellow African immigrants, a Congolese waiter and a Kenyan engineer, who share his feelings of frustration with and bitter nostalgia for their home continent. Years ago, half a world away and still In the embrace of family, he never would have imagined himself living a life of such isolation."."But after a long period of blight, Sepha's neighborhood begins to change. Hope comes In the form of new neighbors - Judith and Naomi, a white woman and her biracial daughter - who restore the grand, dilapidated house next door. They become his friends and remind him for the first time In years of what having a family Is like. But their arrival signals something more profound for the neighborhood's long time residents, and when its newfound calm is disturbed by a series of racial Incidents, Sepha may lose everything all over again."

"One of the most exciting developments from the world of ideas in decades, presented with panache by two frighteningly brilliant, endearingly unpretentious, and endlessly creative young scientists."--Steven Pinker, author of The Better Angels of Our Nature Our society has gone from writing snippets of information by hand to generating a vast flood of 1s and 0s that record almost every aspect of our lives: who we know, what we do, where we go, what we buy, and who we love. This year, the world will generate 5 zettabytes of data. (That's a five with twenty-one zeros after it.) Big data is revolutionizing the sciences, transforming the humanities, and renegotiating the boundary between industry and the ivory tower. What is emerging is a new way of understanding our world, our past, and possibly, our future. In Uncharted, Erez Aiden and Jean-Baptiste Michel tell the story of how they tapped into this sea of information to create a new kind of telescope: a tool that, instead of uncovering the motions of distant stars, charts trends in human history across the centuries. By teaming up with Google, they were able to analyze the text of millions of books. The result was a new field of research and a scientific tool, the Google Ngram Viewer, so groundbreaking that its public release made the front page of The New York Times, The Wall Street Journal, and The Boston Globe, and so addictive that Mother Jones called it "the greatest timewaster in the history of the internet." Using this scope, Aiden and Michel-and millions of users worldwide-are beginning to see answers to a dizzying array of once intractable questions. How quickly does technology spread? Do we talk less about God today? When did people start "having sex" instead of "making love"? At what age do the most famous people become famous? How fast does grammar change? Which writers had their works most effectively censored by the Nazis? When did the spelling "donut" start replacing the venerable "doughnut"? Can we predict the future of human history? Who is better known-Bill Clinton or the rutabaga? All over the world, new scopes are popping up, using big data to quantify the human experience at the grandest scales possible. Yet dangers lurk in this ocean of 1s and 0s-threats to privacy and the specter of ubiquitous government surveillance. Aiden and Michel take readers on a voyage through these uncharted waters""Breaking open Big Data, two Harvard scientists reveal a ground-breaking way of looking at history and culture""
