Snake River Skies The Newsletter of the Magic Valley Astronomical Society www.mvastro.org Membership Meeting MVAS President’s Message August 2019 Saturday, August 10th 2019 7:00pm at the Herrett Center for Arts & Science College of Southern Idaho. Colleagues, Public Star Party follows at the I hope you found the third week of July exhilarating. The 50th Anniversary of the first Centennial Observatory moon landing was the common theme. I capped my observance by watching the C- SPAN replay of the CBS broadcast. It was not only exciting to watch the landing, but Club Officers to listen to Walter Cronkite and Wally Schirra discuss what Neil Armstrong and Buzz Robert Mayer, President Aldrin was relaying back to us. It was fascinating to hear what we have either accepted or rejected for years come across as something brand new. Hearing [email protected] Michael Collins break in from his orbit above in the command module also reminded me of the major role he played and yet others in the past have often overlooked – Gary Leavitt, Vice President fortunately, he is now receiving the respect he deserves. If you didn’t catch that, [email protected] then hopefully you caught some other commemoration, such as Turner Classic Movies showing For All Mankind, a spellbinding documentary of what it was like for Dr. Jay Hartwell, Secretary all of the Apollo astronauts who made it to the moon. Jim Tubbs, Treasurer / ALCOR For me, these moments of commemoration made reading the moon landing’s [email protected] anniversary issue from the Association of Lunar and Planetary Observers (ALPO) 208-404-2999 come to life as they wrote about the features these astronauts were examining – including the little craters named after the three astronauts. -

COMPETENCES : ● Utilisation du théorème de Pythagore ● Utilisation de Google Earth pour évaluer des distances à vol d'oiseau ● Recherche personnelle de données REALISATION : Il s'agit ici de mettre en application le théorème de Pythagore mais avec une vision terrestre dans un premier temps suite à un questionnement de l'élève puis dans un second temps de réutiliser la même démarche dans le cadre spatial de la visibilité d'un satellite. Fiche élève ____________________________________________________________________________ 1. Victor Hugo a écrit dans Les Châtiments : "Les horizons aux horizons succèdent […] : on avance toujours, on n’arrive jamais ". Face à la mer, vous voyez l'horizon à perte de vue. Mais "est-ce loin, l'horizon ?". D'après toi, jusqu'à quelle distance peux-tu voir si le temps est clair ? Réponse 1 : " Sans instrument, je peux voir jusqu'à .................. km " Réponse 2 : " Avec une paire de jumelles, je peux voir jusqu'à ............... km " 2. Nous allons maintenant calculer à l'aide du théorème de Pythagore la ligne d'horizon pour une hauteur H donnée. -

This has been the Year of the Baryon. Some low temperature ones were seen at high redshift, some high temperature ones were seen at low redshift, and some cooling ones were (probably) reheated. Astronomers saw the back of the Sun (which is also made of baryons), a possible solution to the problem of ejection of material by Type II supernovae (in which neutrinos push out baryons), the production of R Coronae Borealis stars (previously-owned baryons), and perhaps found the missing satellite galaxies (whose failing is that they have no baryons). A few questions were left unanswered for next year, and an attempt is made to discuss these as well. -

HAMLET's MILL.Pdf
Hamlet's Mill An essay on myth and the frame of time GIORGIO de SANTILLANA Professor of the History and Philosophy of Science M.l.T. and HERTHA von DECHEND apl. Professor fur Geschichte der Naturivissenschaften ]. W. Goethe-Universitat Frankfurt Preface ASthe senior, if least deserving, of the authors, I shall open the narrative. Over many years I have searched for the point where myth and science join. It was clear to me for a long time that the origins of science had their deep roots in a particular myth, that of invariance. The Greeks, as early as the 7th century B.C., spoke of the quest of their first sages as the Problem of the One and the Many, sometimes describing the wild fecundity of nature as the way in which the Many could be deduced from the One, sometimes seeing the Many as unsubstantial variations being played on the One. The oracular sayings of Heraclitus the Obscure do nothing but illustrate with shimmering paradoxes the illusory quality of "things" in flux as they were wrung from the central intuition of unity. Before him Anaximander had announced, also oracularly, that the cause of things being born and perishing is their mutual injustice to each other in the order of time, "as is meet," he said, for they are bound to atone forever for their mutual injustice. This was enough to make of Anaximander the acknowledged father of physical science, for the accent is on the real "Many." But it was true science after a fashion. Soon after, Pythagoras taught, no less oracularly, that "things are numbers." Thus mathematics was born. -
ESO Annual Report 2004 ESO Annual Report 2004 Presented to the Council by the Director General Dr
ESO Annual Report 2004 ESO Annual Report 2004 presented to the Council by the Director General Dr. Catherine Cesarsky View of La Silla from the 3.6-m telescope. ESO is the foremost intergovernmental European Science and Technology organi- sation in the field of ground-based as- trophysics. It is supported by eleven coun- tries: Belgium, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Sweden, Switzerland and the United Kingdom. Created in 1962, ESO provides state-of- the-art research facilities to European astronomers and astrophysicists. In pur- suit of this task, ESO’s activities cover a wide spectrum including the design and construction of world-class ground-based observational facilities for the member- state scientists, large telescope projects, design of innovative scientific instruments, developing new and advanced techno- logies, furthering European co-operation and carrying out European educational programmes. ESO operates at three sites in the Ataca- ma desert region of Chile. The first site The VLT is a most unusual telescope, is at La Silla, a mountain 600 km north of based on the latest technology. It is not Santiago de Chile, at 2 400 m altitude. just one, but an array of 4 telescopes, It is equipped with several optical tele- each with a main mirror of 8.2-m diame- scopes with mirror diameters of up to ter. With one such telescope, images 3.6-metres.
