His apothegm "Cogito, ergo sum" marked the birth of the mind-body problem, while his creation of so-called Cartesian coordinates have made our physical and intellectual conquest of physical space possible.But Descartes had a mysterious and mystical side, as well. Almost certainly a member of the occult brotherhood of the Rosicrucians, he kept a secret notebook, now lost, most of which was written in code. After Descartes's death, Gottfried Leibniz, inventor of calculus and one of the greatest mathematicians in history, moved to Paris in search of this notebook--and eventually found it in the possession of Claude Clerselier, a friend of Descartes. Leibniz called on Clerselier and was allowed to copy only a couple of pages--which, though written in code, he amazingly deciphered there on the spot. Leibniz's hastily scribbled notes are all we have today of Descartes's notebook, which has disappeared.Why did Descartes keep a secret notebook, and what were its contents? The answers to these questions lead Amir Aczel and the reader on an exciting, swashbuckling journey, and offer a fascinating look at one of the great figures of Western culture.

    Most know Richard Feynman for the hilarious anecdotes and exploits in his best-selling books Surely You're Joking, Mr. Feynman! and What DoYou Care What Other People Think? But not always obvious in those stories was his brilliance as a pure scientist—one of the century's greatest physicists. With this book and CD, we hear the voice of the great Feynman in all his ingenuity, insight, and acumen for argument. This breathtaking lecture—"The Motion of the Planets Around the Sun"—uses nothing more advanced than high-school geometry to explain why the planets orbit the sun elliptically rather than in perfect circles, and conclusively demonstrates the astonishing fact that has mystified and intrigued thinkers since Newton: Nature obeys mathematics. David and Judith Goodstein give us a beautifully written short memoir of life with Feynman, provide meticulous commentary on the lecture itself, and relate the exciting story of their effort to chase down one of Feynman's most original and scintillating lectures.

    A full-blooded Sioux, he was many things in the white man's world -- rodeo clown, painter, prisioner. But, above all, he was a holy man of the Lakota tribe. Seeker of Vision The story he tells is one of harsh youth and reckless manhood, shotgun marriage and divorce, history and folklore as rich today as ever -- and of his fierce struggle to keep pride alive, though living as a stranger in his own ancestral land.

    It has the marks of greatness in it--style, scope, imagination, laughter, tragedy."--From the Introduction by Charles NeiderMark Twain was a figure larger than life: massive in talent, eruptive in temperament, unpredictable in his actions. He crafted stories of heroism, adventure, tragedy, and comedy that reflected the changing America of the time, and he tells his own story--which includes sixteen pages of photos--with the same flair he brought to his fiction. Writing this autobiography on his deathbed, Twain vowed to he "free and frank and unembarrassed" in the recounting of his life and his experiences. Twain was more than a match for the expanding America of riverboats, gold rushes, and the vast westward movement, which provided the material for his novels and which served to inspire this beloved and uniquely American autobiography.

    With candor, insight, and tremendous humor, Bragg seamlessly weaves these luminous narrative threads together and delivers an unforgettable rumination about fathers and sons.

    From the emergence of life at deep-sea vents to solar-powered starships sailing through the galaxy, from the Big Bang to the intricacies of intelligence in many life forms, acclaimed author Ann Druyan documents where humanity has been and where it is going, using her unique gift of bringing complex scientific concepts to life. With evocative photographs and vivid illustrations, she recounts momentous discoveries, from the Voyager missions in which she and her husband, Carl Sagan, participated to Cassini-Huygens's recent insights into Saturn's moons. This breathtaking sequel to Sagan's masterpiece explains how we humans can glean a new understanding of consciousness here on Earth and out in the cosmos--again reminding us that our planet is a pale blue dot in an immense universe of possibility.

    When he learned how to see again, he didn't want anyone's pity. People shouldn't feel sorry for him, he decided, and they shouldn't feel sorry for themselves either. Most people's everyday challenges aren't as extreme as surviving combat or working to regain their sight, but that's just Crenshaw's point: If we can meet life's toughest challenges without resenting our luck or complaining, minor daily obstacles aren't worth our outrage. "Microaggressions" and "triggers" from mere words mean little to someone who's had bullets fly by their head. That's Crenshaw's simple lesson in FORTITUDE: Lighten up, toughen up, and get to work on what's important (hint: it's not giving into a culture of outrage, playing the victim, and seeking an apology).FORTITUDE is a no-nonsense advice book for a society desperately in need of tough love. With meditations on perseverance, failure, and finding much-needed heroes, the book is the antidote for a prevailing "safety culture" of trigger warnings and safe spaces. Interspersed with lessons and advice is Crenshaw's own story of how an average American kid from the Houston suburbs has faced all sorts of unexpected situations -- from war zones to the halls of Congress -- and managed to navigate them all with a few simple tricks: a sense of humor and an even greater sense that, no matter what anyone else around us says or does, we are in control of our own destiny.

    Michael Guillen, known to millions as the science editor of ABC's Good Morning America, tells the fascinating stories behind five mathematical equations. As a regular contributor to daytime's most popular morning news show and an instructor at Harvard University, Dr. Michael Guillen has earned the respect of millions as a clear and entertaining guide to the exhilarating world of science and mathematics. Now Dr. Guillen unravels the equations that have led to the inventions and events that characterize the modern world, one of which -- Albert Einstein's famous energy equation, E=mc2 -- enabled the creation of the nuclear bomb. Also revealed are the mathematical foundations for the moon landing, airplane travel, the electric generator -- and even life itself. Praised by Publishers Weekly as "a wholly accessible, beautifully written exploration of the potent mathematical imagination," and named a Best Nonfiction Book of 1995, the stories behind The Five Equations That Changed the World, as told by Dr. Guillen, are not only chronicles of science, but also gripping dramas of jealousy, fame, war, and discovery.

    You just saw a little boxing. You saw only a part of me. After I retired from boxing my true work began. I have embarked on a journey of love." So Muhammad Ali begins this spiritual memoir, his description of the values that have shaped and sustained him and that continue to guide his life. In The Soul of a Butterfly the great champion takes readers on a spiritual journey through the seasons of life, from childhood to the present, and shares the beliefs that have served him well.After fighting some of the fiercest bouts in boxing history against Joe Frazier and George Foreman, today Muhammad Ali faces his most powerful foe -- outside the boxing ring. Like many people, he battles an illness that limits his physical abilities, but as he says, "I have gained more than I have lost....I have never had a more powerful voice than I have now." Ali reflects on his faith in God and the strength it gave him during his greatest challenge, when he lost the prime years of his boxing career because he would not compromise his beliefs. He describes how his study of true Islam has helped him accept the changes in his life and has brought him to a greater awareness of life's true purpose. As a United Nations "Messenger of Peace," he has traveled widely, and he describes his 2002 mission to Afghanistan to heighten public awareness of that country's desperate situation, as well as his more recent meeting with the Dalai Lama.Ali's reflections on topics ranging from moral courage to belief in God to respect for those who differ from us will inspire and enlighten all who read them. Written with the assistance of his daughter Hana, The Soul of a Butterfly is a compassionate and heartfelt book that will provide comfort for our troubled times.
