Roosevelt expresses her philosophy of life by relating the experiences which have enabled her to cope with personal and public responsibilities.

    Now, she's clean and sober, a married mother of three. As she found her way in her new life, she started sharing on social media as an outlet for her depression and anxiety. She struck a chord, several of her videos went viral (one with 46million views), and in the past year her following exploded from a few hundred thousand to more than 3 million.The memoir opens in the Florida women's prison where Tiffany was incarcerated for 180 days. The memoir flashes back in time to the events that led to Tiffany's imprisonment (during the time of her active addiction, Tiffany was dating and living with a cop), and moves forward to her eventual sobriety.

    do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    An unremarkable student, he nearly flunked out of high school. After being drafted into the army, he enlisted in the navy and went to Vietnam, where the life and death struggles he encountered as a medic piqued his interest in science and medicine. After pursuing his advanced degrees, Venter quickly established himself as a brilliant and outspoken scientist. In 1984 he joined the National Institutes of Health, where he introduced novel techniques for rapid gene discovery, and left in 1991 to form his own nonprofit genomics research center, where he sequenced the first genome in history in 1995. In 1998 he announced that he would successfully sequence the human genome years earlier, and for far less money, than the government-sponsored Human Genome Project would— a prediction he kept in 2001. A Life Decoded is the triumphant story of one of the most fascinating and controversial figures in science today. In his riveting and inspiring account Venter tells of the unparalleled drama of the quest for the human genome, a tale that involves as much politics (personal and political) as science. He also reveals how he went on to be the first to read and interpret his own genome and what it will mean for all of us to do the same. He describes his recent sailing expedition to sequence microbial life in the ocean, as well as his groundbreaking attempt to create synthetic life. Here is one of the key scientific chronicles of our lifetime, as told by the man who beat the odds to make it happen.

    Now he brings his considerable talents to the history of one of math's most enduring puzzles: the seemingly paradoxical nature of infinity.Is infinity a valid mathematical property or a meaningless abstraction? The nineteenth-century mathematical genius Georg Cantor's answer to this question not only surprised him but also shook the very foundations upon which math had been built. Cantor's counterintuitive discovery of a progression of larger and larger infinities created controversy in his time and may have hastened his mental breakdown, but it also helped lead to the development of set theory, analytic philosophy, and even computer technology.Smart, challenging, and thoroughly rewarding, Wallace's tour de force brings immediate and high-profile recognition to the bizarre and fascinating world of higher mathematics.

    xn + yn = zn, where n represents 3, 4, 5, ...no solution"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations.  What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years.  In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it.  Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.

    Written in conjunction with Samuel Crowther, "My Life and Work" chronicles the rise and success of one of the greatest American entrepreneurs and businessmen. Henry Ford and the Ford Motor Company will forever be identified with early 20th century American industrialism. The innovations to business and direct impact on the American economy of Henry Ford and his company are immeasurable. His story is brilliantly chronicled in this classic American biography.

    Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee

    Exploring his past with humor and astounding insight, Connor reminded his fans of why they first fell in love with him on YouTube—and revealed to newcomers how he relates to his millions of dedicated followers.Now, two years later, Connor is ready to bring to light a side of himself he’s rarely shown on or off camera. In this diary-like look at his life since A Work In Progress, Connor talks about his battles with clinical depression, social anxiety, self-love, and acceptance; his desire to maintain an authentic self in a world that values shares and likes over true connections; his struggles with love and loss; and his renewed efforts to be in the moment—with others and himself.Told through short essays, letters to his past and future selves, poetry, and original photography, Note to Self is a raw, in-the-moment look at the fascinating interior life of a young creator turning inward in order to move forward.

    Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye. The debate culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.Filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is Mike Brown’s engaging first-person account of the most tumultuous year in modern astronomy—which he inadvertently caused. As it guides readers through important scientific concepts and inspires us to think more deeply about our place in the cosmos, it is also an entertaining and enlightening personal story: While Brown sought to expand our understanding of the vast nature of space, his own life was changed in the most immediate, human ways by love, birth, and death. A heartfelt and personal perspective on the demotion of everyone’s favorite farflung planet, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever dreamed of exploring the universe—and who among us hasn’t?

    Based on more than forty interviews with Steve Jobs conducted over two years--as well as interviews with more than 100 family members, friends, adversaries, competitors, and colleagues--Walter Isaacson has written a riveting story of the roller-coaster life and searingly intense personality of a creative entrepreneur whose passion for perfection and ferocious drive revolutionized six industries: personal computers, animated movies, music, phones, tablet computing, and digital publishing. Isaacson's portrait touched millions of readers. At a time when America is seeking ways to sustain its innovative edge, Jobs stands as the ultimate icon of inventiveness and applied imagination. He knew that the best way to create value in the twenty-first century was to connect creativity with technology. He built a company where leaps of the imagination were combined with remarkable feats of engineering. Although Jobs cooperated with the author, he asked for no control over what was written. He put nothing off-limits. He encouraged the people he knew to speak honestly. He himself spoke candidly about the people he worked with and competed against. His friends, foes, and colleagues offer an unvarnished view of the passions, perfectionism, obsessions, artistry, devilry, and compulsion for control that shaped his approach to business and the innovative products that resulted. His tale is instructive and cautionary, filled with lessons about innovation, character, leadership, and values. Steve Jobs is the inspiration for the movie of the same name starring Michael Fassbender, Kate Winslet, Seth Rogen, and Jeff Daniels, directed by Danny Boyle with a screenplay by Aaron Sorkin.
