Today’s "machine-learning" systems, trained by data, are so effective that we’ve invited them to see and hear for us?and to make decisions on our behalf. But alarm bells are ringing. Recent years have seen an eruption of concern as the field of machine learning advances. When the systems we attempt to teach will not, in the end, do what we want or what we expect, ethical and potentially existential risks emerge. Researchers call this the alignment problem.Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole?and appear to assess Black and White defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And as autonomous vehicles share our streets, we are increasingly putting our lives in their hands.The mathematical and computational models driving these changes range in complexity from something that can fit on a spreadsheet to a complex system that might credibly be called “artificial intelligence.” They are steadily replacing both human judgment and explicitly programmed software.In best-selling author Brian Christian’s riveting account, we meet the alignment problem’s “first-responders,” and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they—and we—succeed or fail in solving the alignment problem will be a defining human story.The Alignment Problem offers an unflinching reckoning with humanity’s biases and blind spots, our own unstated assumptions and often contradictory goals. A dazzlingly interdisciplinary work, it takes a hard look not only at our technology but at our culture—and finds a story by turns harrowing and hopeful.

    It intersects with Darwin’s theory of evolution, and collides with the horrors of Nazi eugenics in the 1940s. The gene transforms post-war biology. It reorganizes our understanding of sexuality, temperament, choice and free will. This is a story driven by human ingenuity and obsessive minds – from Charles Darwin and Gregor Mendel to Francis Crick, James Watson and Rosalind Franklin, and the thousands of scientists still working to understand the code of codes.This is an epic, moving history of a scientific idea coming to life, by the author of The Emperor of All Maladies. But woven through The Gene, like a red line, is also an intimate history – the story of Mukherjee’s own family and its recurring pattern of mental illness, reminding us that genetics is vitally relevant to everyday lives. These concerns reverberate even more urgently today as we learn to “read” and “write” the human genome – unleashing the potential to change the fates and identities of our children.Majestic in its ambition, and unflinching in its honesty, The Gene gives us a definitive account of the fundamental unit of heredity – and a vision of both humanity’s past and future.

    Robert Oppenheimer, the brilliant, charismatic head of the Manhattan Project, recruited scientists to live as virtual prisoners of the U.S. government at Los Alamos, a barren mesa thirty-five miles outside Santa Fe, New Mexico. Thousands of men, women, and children spent the war years sequestered in this top-secret military facility. They lied to friends and family about where they were going and what they were doing, and then disappeared into the desert. Through the eyes of a young Santa Fe widow who was one of Oppenheimer's first recruits, we see how, for all his flaws, he developed into an inspiring leader and motivated all those involved in the Los Alamos project to make a supreme effort and achieve the unthinkable.

    But James Oakes’s brilliant history of Lincoln’s antislavery strategies reveals a striking consistency and commitment extending over many years. The linchpin of antislavery for Lincoln was the Constitution of the United States.Lincoln adopted the antislavery view that the Constitution made freedom the rule in the United States, slavery the exception. Where federal power prevailed, so did freedom. Where state power prevailed, that state determined the status of slavery, and the federal government could not interfere. It would take state action to achieve the final abolition of American slavery. With this understanding, Lincoln and his antislavery allies used every tool available to undermine the institution. Wherever the Constitution empowered direct federal action—in the western territories, in the District of Columbia, over the slave trade—they intervened. As a congressman in 1849 Lincoln sponsored a bill to abolish slavery in Washington, DC. He reentered politics in 1854 to oppose what he considered the unconstitutional opening of the territories to slavery by the Kansas–Nebraska Act. He attempted to persuade states to abolish slavery by supporting gradual abolition with compensation for slaveholders and the colonization of free Blacks abroad.President Lincoln took full advantage of the antislavery options opened by the Civil War. Enslaved people who escaped to Union lines were declared free. The Emancipation Proclamation, a military order of the president, undermined slavery across the South. It led to abolition by six slave states, which then joined the coalition to affect what Lincoln called the "King’s cure": state ratification of the constitutional amendment that in 1865 finally abolished slavery.

    When the great blizzard of 1888 crippled the entire northeast, a solution had to be found. Two brothers from one of the nation's great families-Henry Melville Whitney of Boston and William Collins Whitney of New York-pursued the dream of his city digging America's first subway, and the great race was on. The competition between Boston and New York played out in an era not unlike our own, one of economic upheaval, life-changing innovations, class warfare, bitter political tensions, and the question of America's place in the world.The Race Underground is peopled with the famous, like Boss Tweed, Grover Cleveland and Thomas Edison, and the not-so-famous, from brilliant engineers to the countless "sandhogs" who shoveled, hoisted and blasted their way into the earth's crust, sometimes losing their lives in the construction of the tunnels. Doug Most chronicles the science of the subway, looks at the centuries of fears people overcame about traveling underground and tells a story as exciting as any ever ripped from the pages of U.S. history. The Race Underground is a great American saga of two rival American cities, their rich, powerful and sometimes corrupt interests, and an invention that changed the lives of millions.

    Yet Kissinger was also reviled by large segments of the American public, ranging from liberal intellectuals to conservative activists. Kissinger explores the relationship between this complex man's personality and the foreign policy he pursued. Drawing on extensive interviews with Kissinger as well as 150 other sources, including U.S. presidents and his business clients, this first full-length biography makes use of many of Kissinger's private papers and classified memos to tell his uniquely American story. The result is an intimate narrative, filled with surprising revelations, that takes this grandly colorful statesman from his childhood as a persecuted Jew in Nazi Germany, through his tortured relationship with Richard Nixon, to his later years as a globe-trotting business consultant.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    Stargazing is a pursuit that continues to fascinate us: from Copernicus to Carl Sagan, astronomers throughout history have spent their lives trying to answer the biggest questions in the universe. Now, award-winning astronomer Emily Levesque shares the stories of modern-day stargazers, the people willing to adventure across high mountaintops and to some of the most remote corners of the planet, all in the name of science.From the lonely quiet of midnight stargazing to tall tales of wild bears loose in the observatory, The Last Stargazers is a love letter to astronomy and an affirmation of the crucial role that humans can and must play in the future of scientific discovery.In this sweeping work of narrative science, Levesque shows how astronomers in this scrappy and evolving field are going beyond the machines to infuse creativity and passion into the stars and inspires us all to peer skyward in pursuit of the universe's secrets.
