Book Description
Almost from its inception, Einstein's general theory of relativity was known to sanction spacetime models harboring singularities. Until the 1960s, however, spacetime singularities were thought to be artifacts of the idealizations of the models. This attitude evaporated in the face of a series of theorems, due largely to Stephen Hawking and Roger Penrose, which showed that Einstein's general theory implies that singularities can be expected to occur in a wide variety of conditions in both gravitational collapse and in cosmology. In the light of these results some physicists adopted the attitude that, since spacetime singularities are intolerable, general relativity contains within itself the seeds of its own destruction. Others hoped that peaceful coexistence with singularities could be achieved by proving a form of Roger Penrose's cosmic censorship hypothesis, which would place singularities safely inside black holes. Whatever the attitude one adopts toward spacetime singularities, it is evident that they raise a number of foundational problems for physics and have profound implications for the philosophy of space and time. However, philosophers of science have been slow to awaken to the significance of these developments. Indeed, this is the first serious book-length study of the subject by a philosopher of science. It features an overview of the literature on singularities, as well as an analytic commentary on their significance to a number of scientific and philosophical issues.

Book Description
Master verbalist Richard Lederer, America's "Wizard of Idiom" (Denver Post), presents a love letter to the most glorious of human achievements... Welcome to Richard Lederer's beguiling celebration of language -- of our ability to utter, write, and receive words. No purists need stop here. Mr. Lederer is no linguistic sheriff organizing posses to hunt down and string up language offenders. Instead, join him "In Praise of English," and discover why the tongue described in Shakespeare's day as "of small reatch" has become the most widely spoken language in history: English never rejects a word because of race, creed, or national origin. Did you know that jukebox comes from Gullah and canoe from Haitian Creole? Many of our greatest writers have invented words and bequeathed new expressions to our eveyday conversations. Can you imagine making up almost ten percent of our written vocabulary? Scholars now know that William Shakespeare did just that! He also points out the pitfalls and pratfalls of English. If a man mans a station, what does a woman do? In the "The Department of Redundancy Department," "Is English Prejudiced?" and other essays, Richard Lederer urges us not to abandon that which makes us human: the capacity to distinguish, discriminate, compare, and evaluate.

Book Description
Described by the author as “a slightly autobiographical and heavily biased book about investing”, Simple But Not Easy won fans among both professional and private investors alike when first released in 2007. The theme of the book is that investment is simpler than non-professionals think it is, in that the rudiments can be expressed in ordinary English and picked up by anybody. It is not a science. But investment is also difficult. People on the outside tend to think that anyone on the inside should be able to do better than the market indices. This is not so. Picking the managers who are likely to do better is a challenge. Richard Oldfield begins with a detailed confession of some of his worst mistakes and what they have taught him. He discusses the different types of investment, why fees matter, and the importance of measuring performance properly. He also outlines what to look for (and what not to look for) in an investment manager, when to fire a manager, and how to be a successful client. A cult classic for its candid confessions and sparkling wit, this extended edition of Simple But Not Easy – featuring a new author’s preface and a substantial afterword – remains an indispensable companion for all those interested in the rewarding but enigmatic pursuit of investing.

Book Description
Did the universe begin to exist? If so, did it have a cause? Or could it have come into existence uncaused, from nothing? These questions are taken up by the medieval-though recently-revived-kalam cosmological argument, which has arguably been the most discussed philosophical argument for God's existence in recent decades. The kalam's line of reasoning maintains that the series of past events cannot be infinite but rather is finite. Since the universe could not have come into being uncaused, there must be a transcendent cause of the universe's beginning, a conclusion supportive of theism. This anthology on the philosophical arguments for the finitude of the past asks: Is an infinite series of past events metaphysically possible? Should actual infinites be restricted to theoretical mathematics, or can an actual infinite exist in the concrete world? These essays by kalam proponents and detractors engage in lively debate about the nature of infinity and its conundrums; about frequently-used kalam argument paradoxes of Tristram Shandy, the Grim Reaper, and Hilbert's Hotel; and about the infinity of the future.

Book Description
"This girl is a real novelist," wrote Caroline Gordon about Flannery O'Connor upon being asked to review a manuscript of O'Connor's first novel, Wise Blood. "She is already a rare phenomenon: a Catholic novelist with a real dramatic sense, one who relies more on her technique than her piety." This collection of letters and other documents offers the most complete portrait of the relationship between two of the American South's most acclaimed twentieth-century writers: Flannery O'Connor and Caroline Gordon. Gordon (1895-1981) had herself been a protégée of an important novelist, Ford Madox Ford, before publishing nine novels and three short story collections of her own, most notably, The Forest of the South and Old Red and Other Stories, and she would offer insights and friendship to O'Connor during almost all of O'Connor's career. As revealed in this collection of correspondence, Gordon's thirteen-year friendship with O'Connor (1925-64) and the critiques of O'Connor's fiction that she wrote during this time not only fostered each writer's career but occasioned a remarkable series of letters full of insights about the craft of writing. Gordon, a more established writer at the start of their correspondence, acted as a mentor to the younger O'Connor and their letters reveal Gordon's strong hand in shaping some of O'Connor's most acclaimed work, including Wise Blood, "A Good Man Is Hard to Find," and "The Displaced Person."
