  • Nagy Commentary on Euripides, Herakles
    Informal Commentary on Euripides, Herakles by Gregory Nagy 97 The idea of returning from Hades implies a return from death 109f The mourning swan... Cf. the theme of the swansong. Cf. 692ff. 113 “The phantom of a dream”: cf. skias onar in Pindar Pythian 8. 131f “their father’s spirit flashing from their eyes”: beautiful rendition! 145f Herakles’ hoped-for return from Hades is equated with a return from death, with resurrection; see 297, where this theme becomes even more overt; also 427ff. 150 Herakles as the aristos man: not that he is regularly described in this drama as the best of all humans, not only of the “Greeks” (also at 183, 209). See also the note on 1306. 160 The description of the bow as “a coward’s weapon” is relevant to the Odysseus theme in the Odyssey 203 sôzein to sôma ‘save the body’... This expression seems traditional: if so, it may support the argument of some linguists that sôma ‘body’ is derived from sôzô ‘save’. By metonymy, the process of saving may extend to the organism that is destined to be saved. 270 The use of kleos in the wording of the chorus seems to refer to the name of Herakles; similarly in the wording of Megara at 288 and 290. Compare the notes on 1334 and 1369. 297 See at 145f above. Cf. the theme of Herakles’ wrestling with Thanatos in Euripides Alcestis. 342ff Note the god-hero antagonism as expressed by Amphitryon. His claim that he was superior to Zeus in aretê brings out the meaning of ‘striving’ in aretê (as a nomen actionis derived from arnumai; cf.

  • The Pancam Instrument for the Exomars Rover
    ASTROBIOLOGY ExoMars Rover Mission Volume 17, Numbers 6 and 7, 2017 Mary Ann Liebert, Inc. DOI: 10.1089/ast.2016.1548 The PanCam Instrument for the ExoMars Rover A.J. Coates,1,2 R. Jaumann,3 A.D. Griffiths,1,2 C.E. Leff,1,2 N. Schmitz,3 J.-L. Josset,4 G. Paar,5 M. Gunn,6 E. Hauber,3 C.R. Cousins,7 R.E. Cross,6 P. Grindrod,2,8 J.C. Bridges,9 M. Balme,10 S. Gupta,11 I.A. Crawford,2,8 P. Irwin,12 R. Stabbins,1,2 D. Tirsch,3 J.L. Vago,13 T. Theodorou,1,2 M. Caballo-Perucha,5 G.R. Osinski,14 and the PanCam Team Abstract The scientific objectives of the ExoMars rover are designed to answer several key questions in the search for life on Mars. In particular, the unique subsurface drill will address some of these, such as the possible existence and stability of subsurface organics. PanCam will establish the surface geological and morphological context for the mission, working in collaboration with other context instruments. Here, we describe the PanCam scientific objectives in geology, atmospheric science, and 3-D vision. We discuss the design of PanCam, which includes a stereo pair of Wide Angle Cameras (WACs), each of which has an 11-position filter wheel and a High Resolution Camera (HRC) for high-resolution investigations of rock texture at a distance. The cameras and electronics are housed in an optical bench that provides the mechanical interface to the rover mast and a planetary protection barrier.

  • Hesiod Theogony.Pdf
    Hesiod (8th or 7th c. BC, composed in Greek) The Homeric epics, the Iliad and the Odyssey, are probably slightly earlier than Hesiod’s two surviving poems, the Works and Days and the Theogony. Yet in many ways Hesiod is the more important author for the study of Greek mythology. While Homer treats cer- tain aspects of the saga of the Trojan War, he makes no attempt at treating myth more generally. He often includes short digressions and tantalizes us with hints of a broader tra- dition, but much of this remains obscure. Hesiod, by contrast, sought in his Theogony to give a connected account of the creation of the universe. For the study of myth he is im- portant precisely because his is the oldest surviving attempt to treat systematically the mythical tradition from the first gods down to the great heroes. Also unlike the legendary Homer, Hesiod is for us an historical figure and a real per- sonality. His Works and Days contains a great deal of autobiographical information, in- cluding his birthplace (Ascra in Boiotia), where his father had come from (Cyme in Asia Minor), and the name of his brother (Perses), with whom he had a dispute that was the inspiration for composing the Works and Days. His exact date cannot be determined with precision, but there is general agreement that he lived in the 8th century or perhaps the early 7th century BC. His life, therefore, was approximately contemporaneous with the beginning of alphabetic writing in the Greek world. Although we do not know whether Hesiod himself employed this new invention in composing his poems, we can be certain that it was soon used to record and pass them on.

Teselkin, Candi- date of PhysicsMathematics,[email protected] V. Vorontsov, Doctor of Engineering Science, [email protected] Lavochkin Association, Russia Mission "Venera-D" by Lavochkin Association implies a long-term study of Venus. International pay- load is to be installed on orbiter, lander and long-living station on Venus surface. The project is a basis for further large-scale international missions to Venus, previously carried out in 1960-80s and early 1990s by Soviet and American spacecraft. A large amount of data on structure, soil composition, atmosphere, cloud layers, wind speed on the surface were accumulated. Soviet Venus research program was completed in 1986 by landing of \VEGA" (Venus-Halley's comet), one of the most successful projects in Lavochkin history. Since 1994 (mapping with the NASA Magellan mission) Venus was studied by two spacecraft: \Venus Express" (ESA, 2005-2014) and \Akatsuki" (JAXA, launch - 2010, start of operation - 2015). The first steps of \Venera-D" appeared in the early 2000s with the idea to provide operations on the planet's surface for several hours and possibly days. With the latest developments, unification of design solutions and new technical tools used in-house Lavochkin experts consider the mission \VEGA" as a prototype for the next automatic interplanetary station destined to Venus.
