Motivated by analogous applications to sonoluminescence, neutron stars mergers are examined in the context of Schwinger's dynamical Casimir effect. When the dielectric properties of the QED vacuum are altered through the introduction of dense matter, energy shifts in the zero-point fluctuations can appear as photon bursts at gamma-ray frequencies. The amount of radiation depends upon the properties and amount of matter in motion and the suddenness of the transition. It is shown that the dynamical Casimir effect can convert sufficient energy (...) of neutron star mergers into gamma rays. Using information extracted from simulations of matter flow in neutron star mergers by Ruffert and Janka, we estimate that the total Casimir energy released can exceed 10 53 ergs in gamma-ray frequencies. The Casimir energy approach is capable of explaining the most energetic gamma-ray bursts. (shrink)

Book reviewed in this article: Rights Talk: The Impoverishment of Political Discourse. By Mary Ann Glendon.

The rediscovery of the force and scope of apocalypticism in primitive Christianity can help systematic theology to find new openings for thoughts of faith that have long languished in systems that obstruct their expression.

Law provides a rich language for thinking about bioethical issues and is a tool for action as well as talk. But the language of the law, often inapt, regularly fails to achieve its desired effect.

The absoluteness of Christianity is a predicate of the God of the eschatological kingdom proclaimed by Jesus, a kingdom embracing the power of a universal future which also includes the entire sweep of the history of religions.

Recent studies indicate that patients who are diagnosed with vegetative states may retain more awareness than their clinical assessments suggest. Disorders of consciousness traditionally have been diagnosed on the basis of outwardly observable behaviors alone, but new functional imaging studies have shown surprising levels of brain activity in some patients, indicating that even higher-level cognitive functions like language processing and visual imagery may be preserved. For example, one recently developed method purports to detect voluntary mental imagery solely on the basis (...) of neural response patterns observed with functional magnetic resonance imaging. This line of research has already led to some widely reported cases of patients who were discovered to have more brain activity than expected. In November 2009, Rom Houben, a Belgian man who was thought to be in a coma for 23 years, was diagnosed with locked-in syndrome through the use of neuroimaging; however, that assessment was later overturned by further testing.

Let us look to America, not in order to make a servile copy of the institutions that she has established, but to gain a clearer view of the polity that will be the best for us; let us look there less to find examples than instruction; let us borrow from her the principles, rather than the details, of her laws. The laws of the French republic may be, and ought to be in many cases, different from those which govern the (...) United States; but the principles on which the American constitutions rest, those principles of order, of the balance of powers, of true liberty, of deep and sincere respect for right, are indispensable to all republics; they ought to be common to all …. —Alexis de Tocqueville Democracy in America.

Though Nietzsche never developed a theory of history, his comments on time yield a radical approach to historical interpretation. Central to this philosophy is the concept of eternal recurrence. Time, with neither boundary nor purpose, returns from the past to repeat itself in its same form. This generates a psychological and moral problem for men, as it fails to provide the elements of meaning which Nietzsche considered essential to the human psyche. Men survive the aimlessness of history by living in (...) the unhistorical consciousness of the immediate present. Nietzsche's ideal is the suprahistorical man, whose awareness of history, and his disgust with it, lead him to find meaning in the structure of time-a structure of meaninglessness. The value system of history is this will to power and precludes the extension of historical judgment to situations beyond the sphere of inquiry. (shrink)

“Christ died for us” is the sine que non of every doctrine of the atonement.

This book examines influential conceptions of sport and then analyses the interplay of challenging borderline cases with the standard definitions of sport. It is meant to inspire more thought and debate on just what sport is, how it relates to other activities and human endeavors, and what we can learn about ourselves by studying sport.
