This dialogue resulted from a discussion which begun a few seven years in the past among a physicist who makes a speciality of astrophysics, common relativity, and the principles of quantum concept, and a pupil of cultural historical past who had performed post-doctoral paintings within the heritage and philosophy of technological know-how. either one of us at the moment have been anticipating the result of a few experiments being carried out below the course of the physicist Alain point on the collage of Paris-South. ! The experiments have been the final in a chain designed to check a few predictions in accordance with a mathematical 2 theorem released in 1964 through John Bell. there has been no expectation that the result of those experiments would offer the foundation for constructing new applied sciences. The questions which the experiments have been designed to reply to involved the relation send among actual truth and actual idea within the department of physics often called quantum mechanics. Like so much questions raised by way of physicists which result in startling new insights, they have been disarmingly uncomplicated and direct. Is quantum physics, requested Bell, a self-consistent thought whose predictions may carry in a brand new classification of experiments, or might the consequences show that the plain demanding situations of quantum physics to the certainty in classical physics of the connection among actual thought and actual fact have been simply illusory? Answering this question in genuine experiments , urged Bell, bring about one other, particularly dramatic, result.

This quantity exhibits how collective magnetic excitations ascertain so much of the magnetic homes of itinerant electron magnets. earlier theories have been almost always constrained to the Curie-Weiss legislations temperature dependence of magnetic susceptibilities. in response to the spin amplitude conservation suggestion together with the zero-point fluctuation amplitude, this ebook exhibits that the whole temperature and magnetic box dependence of magnetization curves, even within the flooring country, is dependent upon the influence of spin fluctuations. It additionally exhibits that the theoretical results are principally in contract with many experimental observations. The readers will consequently achieve a brand new entire viewpoint in their unified figuring out of itinerant electron magnetism.

The Dutch telescope and the Italian scientist Galileo have lengthy loved a sturdy connection within the renowned mind--so a lot in order that it kind of feels this easy glass device reworked a slightly modest middle-aged student into the daring icon of the Copernican Revolution. And but the intense pace with which the telescope replaced the process Galileo's lifestyles and early smooth astronomy obscures the astronomer's personal apparently behind schedule come upon with the device. This booklet considers the lapse among the telescope's construction within the Hague in 1608 and Galileo's alleged acquaintance with such information ten months later. In an inquiry into clinical and cultural heritage, Eileen Reeves explores basic questions of highbrow responsibility: what did Galileo be aware of of the discovery of the telescope, and whilst did he realize it? The checklist means that Galileo, like all of his friends, first and foremost misunderstood the fundamental layout of the telescope. In looking to clarify the space among the telescope's emergence and the alleged date of the astronomer's acquaintance with it, Reeves explores how and why information regarding the telescope used to be transmitted, suppressed, or misconstrued within the method. Her revised model of occasions, rejecting the standard reasons of silence and idleness, is a revealing account of the position that misprision, errors, and preconception play within the development of technological know-how. alongside the best way, Reeves deals a revised chronology of Galileo's lifestyles in a serious interval and, extra usually, exhibits how records in most cases outdoor the scope of early glossy normal philosophy--medieval romances, commute literature, and idle speculations--relate to 2 an important occasions within the heritage of technological know-how.

"La cosa pi? incomprensibile del mondo ? il fatto che sia comprensibile", ebbe a dire un giorno Albert Einstein. A ben pensarci, non ? stupefacente che l’Universo abbia un’intima essenza razionale e matematica, story da abilitare l. a. mente umana a indagarlo e a conoscerlo? Questo libro tratta dell’evoluzione storica del concetto di razionalit?, dal mondo greco classico fino ai nostri giorni, passando attraverso i contributi, spesso sottovalutati o mal compresi, dei Padri della Chiesa e dei teologi medievali. Se non si tengono nel giusto conto i risultati del costruttivo e serrato confronto tra scienza e religione sul tema della comprensibilit? del mondo, non si possono cogliere le specificit? delle determine di due "giganti" come Galileo e Newton, della scoperta del metodo scientifico e dei conseguenti trionfi della scienza moderna. L’interazione conflittuale tra scienza e teologia attraversa i secoli e rappresenta una delle pagine pi? entusiasmanti della storia del pensiero umano.
