Impossibility

The Constitution may guarantee it. But religious freedom in America is, in fact, impossible. So argues this timely and iconoclastic work by law and religion scholar Winnifred Sullivan. Sullivan uses as the backdrop for the book the trial of Warner vs. Boca Raton, a recent case concerning the laws that protect the free exercise of religion in America. The trial, for which the author served as an expert witness, concerned regulations banning certain memorials from a multiconfessional nondenominational cemetery in Boca Raton, Florida. The book portrays the unsuccessful struggle of Catholic, Protestant, and Jewish families in Boca Raton to preserve the practice of placing such religious artifacts as crosses and stars of David on the graves of the city-owned burial ground. Sullivan demonstrates how, during the course of the proceeding, citizens from all walks of life and religious backgrounds were harassed to define just what their religion is. She argues that their plight points up a shocking truth: religion cannot be coherently defined for the purposes of American law, because everyone has different definitions of what religion is. Indeed, while religious freedom as a political idea was arguably once a force for tolerance, it has now become a force for intolerance, she maintains. A clear-eyed look at the laws created to protect religious freedom, this vigorously argued book offers a new take on a right deemed by many to be necessary for a free democratic society. It will have broad appeal not only for religion scholars, but also for anyone interested in law and the Constitution. Featuring a new preface by the author, The Impossibility of Religious Freedom offers a new take on a right deemed by many to be necessary for a free democratic society.

A comprehensive look at four of the most famous problems in mathematics Tales of Impossibility recounts the intriguing story of the renowned problems of antiquity, four of the most famous and studied questions in the history of mathematics. First posed by the ancient Greeks, these compass and straightedge problems—squaring the circle, trisecting an angle, doubling the cube, and inscribing regular polygons in a circle—have served as ever-present muses for mathematicians for more than two millennia. David Richeson follows the trail of these problems to show that ultimately their proofs—which demonstrated the impossibility of solving them using only a compass and straightedge—depended on and resulted in the growth of mathematics. Richeson investigates how celebrated luminaries, including Euclid, Archimedes, Viète, Descartes, Newton, and Gauss, labored to understand these problems and how many major mathematical discoveries were related to their explorations. Although the problems were based in geometry, their resolutions were not, and had to wait until the nineteenth century, when mathematicians had developed the theory of real and complex numbers, analytic geometry, algebra, and calculus. Pierre Wantzel, a little-known mathematician, and Ferdinand von Lindemann, through his work on pi, finally determined the problems were impossible to solve. Along the way, Richeson provides entertaining anecdotes connected to the problems, such as how the Indiana state legislature passed a bill setting an incorrect value for pi and how Leonardo da Vinci made elegant contributions in his own study of these problems. Taking readers from the classical period to the present, Tales of Impossibility chronicles how four unsolvable problems have captivated mathematical thinking for centuries.

Three million years ago, the planetary system of Za'nar's connection to the Magic-providing Void Plane was failing. To prevent the disappearance of Za'nar, a Magical Link between it and Earth was created. The Link shares much back and forth between the two systems, including their connection to the Void Plane.Now, one year after the War and the establishment of a parliamentary monarchy in Za'nar, Earth is in trouble. Sael Ageis, accomplished Magi of Za'nar, meets earthlings Klyde Vance and Fae, and together they find themselves drawn into a three million year old Magical conflict, unlocking secrets about the human race.

Astronomer John Barrow takes an intriguing look at the limits of science, who argues that there are things that are ultimately unknowable, undoable, or unreachable.

Kenneth Arrow's pathbreaking Òimpossibility theoremÓ was a watershed in the history of welfare economics, voting theory, and collective choice, demonstrating that there is no voting rule that satisfies the four desirable axioms of decisiveness, consensus, nondictatorship, and independence. In this book, Amartya Sen and Eric Maskin explore the implications of ArrowÕs theorem. Sen considers its ongoing utility, exploring the theoremÕs value and limitations in relation to recent research on social reasoning, while Maskin discusses how to design a voting rule that gets us closer to the idealÑgiven that achieving the ideal is impossible. The volume also contains a contextual introduction by social choice scholar Prasanta K. Pattanaik and commentaries from Joseph E. Stiglitz and Kenneth Arrow himself, as well as essays by Sen and Maskin outlining the mathematical proof and framework behind their assertions.

This book provides an analysis of the treatment of impossibility in modern private law. The author explains the regulation of impossibility in German, Swiss and Turkish laws with a comparative analysis of the subject under (i) the United Nations Convention on International Sale of Goods (CISG), (ii) UNIDROIT Principles of International Commercial Contracts (PICC), (iii) Principles of European Contract Law (PECL also known as the Lando-Principles), (iv) Draft Common Frame of Reference (DCFR) and (iv) Common European Sales Law (CESL).

This book, first published in 1941, provides a comprehensive analysis of impossibility in relation to contract law.

Many of the most famous results in mathematics are impossibility theorems stating that something cannot be done. Good examples include the quadrature of the circle by ruler and compass, the solution of the quintic equation by radicals, Fermat's last theorem, and the impossibility of proving the parallel postulate from the other axioms of Euclidean geometry. This book tells the history of these and many other impossibility theorems starting with the ancient Greek proof of the incommensurability of the side and the diagonal in a square. Lützen argues that the role of impossibility results have changed over time. At first, they were considered rather unimportant meta-statements concerning mathematics but gradually they obtained the role of important proper mathematical results that can and should be proved. While mathematical impossibility proofs are more rigorous than impossibility arguments in other areas of life, mathematicians have employed great ingenuity to circumvent impossibilities by changing the rules of the game. For example, complex numbers were invented in order to make impossible equations solvable. In this way, impossibilities have been a strong creative force in the development of mathematics, mathematical physics, and social science.
