The Energy-Time Uncertainty (ETU) has always been a problem-ridden relation, its problems stemming uniquely from the perplexing question of how to understand this mysterious Δ t . On the face of it (and, indeed, far deeper than that), we always know what time it is. Few theorists were ignorant of the fact that time in quantum mechanics is exogenously defined, in no ways intrinsically related to the system. Time in quantum theory is an independent parameter, which simply means independently known (...) . In the early 1960s Aharonov (1961-64) and Bohm (1961-64) mounted a spirited attack against the ETU, which sealed its fate to the present date. By emphasising that time is always “well-defined” in quantum theory, they were led to the conclusion that no ETU should exist, a view shared by many in the 1990s, if Busch (1990) is to be believed. In a similar vein, I emphasize that (a) physical systems occupy a particular energy state at a particular instant of time, if at all; (b) even in absence of all time-measuring instruments, it is still trivially warranted that one can measure a system's energy as accurately as one pleases, and simply announce “The system's energy is exactly E NOW!”, a possibility which no quantum mechanics of any sort, or any physical theory whatsoever, can afford to tamper with or change, except circularly. One never loses one's own perception of time, when one measures the energy, a fact which no measurement conceivable can interfere with or affect. Both (a) and (b) uniquely entail that energy and time are compatible, if not indeed intimately interconnected, contrary to what the relevant uncertainty seems to affirm. In response to Aharonov's and Bohm's initial problem, I reinterpret ΔEΔt ≥ h , as directly derived from authentic quantum principles, without however having to assume a direct incompatibility between its related concepts, attributing their complementarity to conditions other than ordinarily assumed.

H.B.D. Kettlewell is best known for his pioneering work on the phenomenon of industrial melanism, which began shortly after his appointment in 1951 as a Nuffield Foundation research worker in E.B. Ford's newly formed sub-department of genetics at the University of Oxford. In the years since, a legend has formed around these investigations, one that portrays them as a success story of the 'Oxford School of Ecological Genetics', emphasizes Ford's intellectual contribution, and minimizes reference to assistance provided by others. The (...) following essay reviews the important influence Ford, E.A. Cockayne, and P.M. Sheppard played in Kettlewell's research, leading up to his most famous experiments in 1953. It documents several reasons for doubting that Ford was as intellectually involved in the design of these investigations as he has previously been portrayed. It clarifies Kettlewell's intellectual contribution to the investigations for which he is famous, as well as the pivotal roles Cockayne and Sheppard played in the design, execution and interpretation of these investigations.

Il Poeta e la « Polis » – Colpa e responsabilità in Wystan H. Auden est un livre absolument singulier. Il ne faut pas se fier aux apparences d’un titre qui, pour tout lecteur de Platon, résonne de manière plaisamment familière. Il ne s’agit en rien d’un commentaire de l’exclusion des poètes hors de la cité, évoquée dans l’analyse de la tyrannie au livre VIII de La République. Phénomène inhabituel dans le champ de la réflexion politique, Paolo Carta s’intéresse, en (...) tant qu’historien de la pens.. (shrink)
In Horae canonicae W. H. Auden ha messo a tema la dimensione mimetica della condizione umana. Il saggio ricostruisce in tal senso l’antropologia negativa di Auden, prendendo le mosse dall’analisi del desiderio di riconoscimento quale elemento centrale dell’identità storica. Attraverso una lettura dei motivi della folla e del doppio, e sullo sfondo del poema The Age of Anxiety e della produzione saggistica di Auden, si mostra che la «routine della lode e del biasimo» innesca meccanismi imitativi di sdoppiamento e rivalità (...) che, se da un lato anticipano le tesi di Canetti e Girard, dall’altro rinviano a una concezione mimetico-rituale e mimetico-negativa della poesia.In Horae canonicae W.H. Auden brings into focus the mimetic dimension of human condition. This essay reconstructs Auden's negative anthropology, starting from his analysis of the desire for recognition as a central feature of historical identity. Through an interpretation of the themes of the crowd and of the double, and on the background of the long poem The age of anxiety and of his literary essays, it will be shown that for Auden the «routine of praise and blame» ignites mechanisms of rivalry and doubling that, besides anticipating some ideas of Canetti and Girard, are connected with a ritual and negative mimetic conception of poetry.

Museums are safe spaces for the objects they hold and for the persons that visit them, providing environments that can function in therapeutic ways. Within the wide range of objects, there is enough diversity to help guests discover what similarities they have with others as well as what makes them unique as individuals. Within exhibits, individuals can explore themselves through the reactions they have to particular pieces, through the observation of what holds their attention within the environment, and through the (...) awareness and development of their contemplative mind. Museums can introduce transpersonal information, add information to previous transpersonal experiences, and even promote expanded states of awareness. With direction, guests can use museums to learn about themselves, thus optimizing the therapeutic potentials of these institutions. (shrink)
