Il quinto volume dei «Seminari della Consulta Universitaria del Greco» raccoglie dodici relazioni tenute nel Convegno Delfi e Apollo nella letteratura greca, svoltosi a Delfi dal 29 luglio al 1 agosto 2021. Si è trattato del primo Convegno organizzato dalla «Consulta» al di fuori dei confini italiani e i contributi studiano, sotto vari aspetti e da varie angolazioni, il ruolo di Apollo e del suo santuario nella letteratura del tempo. Fra i vari argomenti, si ricordano lo studio dell’Inno ad Apollo di Alceo, con la ricostruzione della sua natura, del genere e della sua destinazione, e l’analisi della statua aurea che Alessandro I di Macedonia dedicò ad Apollo dopo la battaglia di Platea. Gli inni simposiali ad Apollo vengono indagati in maniera approfondita, dimostrando come essi introducano nell’ambiente del simposio l’elemento corale. È oggetto di analisi la massiccia e complessa presenza della mantica delfica nell’Edipo re e vengono studiati alcuni epiteti che definiscono Apollo nella tragedia attica e contengono giudizi sulla sua competenza profetica. Muovendo dal ruolo ‘incipitario’ che Apollo svolge nella letteratura greca si spiegano alcuni aspetti della biografia di Socrate, quale ci è presentata nei dialoghi platonici. L’ultimo contributo investe le figure del poeta Anghelos Sikelianòs e di sua moglie Eva Palmer, e del loro utopico progetto di proporre Delfi come simbolo di fratellanza universale e centro di dialogo interculturale.

Les ouragans en mer Méditerranée sont des événements météorologiques extrêmes qui influencent les propriétés physico-chimiques de la colonne d’eau. Ce travail s’est concentré sur trois variables : la température, la salinité et la concentration en oxygène dissous pour le Medicane “Apollo” qui a eu lieu fin octobre 2021. Leur évolution est mesurée à l’aide d’appareils in situ (flotteurs Argo et bouées dérivantes) et par satellites. Les données satellites ont subi une reconstruction à l’aide du logiciel DINEOF, qui permet de combler des données manquantes dues à la présence de nuages par exemple. De manière générale, la température et la salinité diminuent dans la couche de mélange lors du passage du Medicane. La concentration en oxygène dissous augmente dans la couche de mélange tout comme la profondeur du maximum de concentration en oxygène dissous. Les principales raisons de ces évolutions sont les échanges enthalpiques et l’évaporation à la surface, les importantes précipitations et les vents engendrées par le Medicane, ainsi que les courants marins et le rayonnement solaire à cette période de l’année. La diminution de la température liée au passage du cyclone augmente également la dissolution de l’oxygène. Une comparaison entre les données in situ et satellitaire montre la complémentarité des deux types de mesures.

A scientist’s inspiring vision of our return to the Moon as humanity’s next thrilling step in space explorationJust over half a century since Neil Armstrong first stepped foot on the lunar surface, a new space race to the Moon is well underway and rapidly gaining momentum. Laying out a vision for the next fifty years, Back to the Moon is astrophysicist Joseph Silk’s persuasive and impassioned case for putting scientific discovery at the forefront of lunar exploration.The Moon offers opportunities beyond our wildest imaginings, and plans to return are rapidly gaining momentum around the world. NASA aims to build a habitable orbiting space station to coordinate lunar development and exploration, while European and Chinese space agencies are planning lunar villages and the mining of precious resources dwindling here on Earth. Powerful international and commercial interests are driving the race to revisit the Moon, but lunar infrastructures could also open breathtaking vistas onto the cosmos. Silk describes how the colonization of the Moon could usher in a thrilling new age of scientific exploration, and lays out what the next fifty years of lunar science might look like. With lunar telescopes of unprecedented size situated in permanently dark polar craters and on the far side of the Moon, we could finally be poised to answer some of the most profound questions confronting humankind, including whether we are alone in the Universe and what our cosmic origins are.Addressing both the daunting challenges and the immense promise of lunar exploration and exploitation, Back to the Moon reveals how prioritizing science, and in particular lunar astronomy, will enable us to address the deepest cosmic mysteries.
