Johannes Kepler, who discovered the three basic laws of planetary motion, was persecuted for his support of the Copernican system. After a neighbour accused his mother of witchcraft, Kepler quit his post as the Imperial mathematician to defend her.James Connor tells Kepler's story as a pilgrimage, a spiritual journey into the modern world through war and disease and terrible injustice, a journey reflected in the evolution of Kepler's geometrical model of the cosmos into a musical model, harmony into greater harmony. The leitmotif of the witch trial adds a third dimension to Kepler's biography by setting his personal life within his own times. The acts of this trial, including Kepler's letters and the accounts of the witnesses, although published in their original German dialects, had never before been translated into English. Echoing some of Dava Sobel's work for Galileo's Daughter, Connor has translated the witch trial documents into English. With a great respect for the history of these times and the life of this man, Connor's accessible story illuminates the life of Kepler, the man of science, but also Kepler, a man of uncommon faith and vision.

    Using Everett's unpublished papers (recently discovered in his son's basement) and dozens of interviews with his friends, colleagues, and surviving family members, Byrne paints, for the general reader, a detailed portrait of the genius who invented an astonishing way of describing our complex universe from the inside. Everett's mathematical model (called the "universal wave function") treats all possible events as "equally real," and concludes that countless copies of every person and thing exist in all possible configurations spread over an infinity of universes: many worlds. Afflicted by depression and addictions, Everett strove to bring rational order to the professional realms in which he played historically significant roles. In addition to his famous interpretation of quantum mechanics, Everett wrote a classic paper in game theory; created computer algorithms that revolutionized military operations research; and performed pioneering work in artificial intelligence for top secret government projects. He wrote the original software for targeting cities in a nuclear hot war; and he was one of the first scientists to recognize the danger of nuclear winter. As a Cold Warrior, he designed logical systems that modeled "rational" human and machine behaviors, and yet he was largely oblivious to the emotional damage his irrational personal behavior inflicted upon his family, lovers, and business partners. He died young, but left behind a fascinating record of his life, including correspondence with such philosophically inclined physicists as Niels Bohr, Norbert Wiener, and John Wheeler. These remarkable letters illuminate the long and often bitter struggle to explain the paradox of measurement at the heart of quantum physics. In recent years, Everett's solution to this mysterious problem-the existence of a universe of universes-has gained considerable traction in scientific circles, not as science fiction, but as an explanation of physical reality.

    He is beloved around the world for his pioneering detective fiction, tales of horror, and haunting, atmospheric verse. But what if there was another side to the man who wrote "The Raven" and "The Fall of the House of Usher"?In The Reason for the Darkness of the Night, John Tresch offers a bold new biography of a writer whose short, tortured life continues to fascinate. Shining a spotlight on an era when the lines separating entertainment, speculation, and scientific inquiry were blurred, Tresch reveals Poe's obsession with science and lifelong ambition to advance and question human knowledge. Even as he composed dazzling works of fiction, he remained an avid and often combative commentator on new discoveries, publishing and hustling in literary scenes that also hosted the era's most prominent scientists, semi-scientists, and pseudo-intellectual rogues. As one newspaper put it, "Mr. Poe is not merely a man of science--not merely a poet--not merely a man of letters. He is all combined; and perhaps he is something more."Taking us through his early training in mathematics and engineering at West Point and the tumultuous years that followed, Tresch shows that Poe lived, thought, and suffered surrounded by science--and that many of his most renowned and imaginative works can best be understood in its company. He cast doubt on perceived certainties even as he hungered for knowledge, and at the end of his life delivered a mind-bending lecture on the origins of the universe that would win the admiration of twentieth-century physicists. Pursuing extraordinary conjectures and a unique aesthetic vision, he remained a figure of explosive contradiction: he gleefully exposed the hoaxes of the era's scientific fraudsters even as he perpetrated hoaxes himself.Tracing Poe's hard and brilliant journey, The Reason for the Darkness of the Night is an essential new portrait of a writer whose life is synonymous with mystery and imagination--and an entertaining, erudite tour of the world of American science just as it was beginning to come into its own.
