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. -

The Aboriginal Australian Cosmic Landscape. Part 1: the Ethnobotany of the Skyworld
Journal of Astronomical History and Heritage, 17(3), 307–325 (2014). THE ABORIGINAL AUSTRALIAN COSMIC LANDSCAPE. PART 1: THE ETHNOBOTANY OF THE SKYWORLD. Philip A. Clarke 17 Duke St, Beulah Park, South Australia 5067, Australia. Email: [email protected] Abstract: In Aboriginal Australia, the corpus of cosmological beliefs was united by the centrality of the Skyworld, which was considered to be the upper part of a total landscape that possessed topography linked with that of Earth and the Underworld. Early historical accounts of classical Australian hunter-gatherer beliefs described the heavens as inhabited by human and spiritual ancestors who interacted with the same species of plants and animals as they had below. This paper is the first of two that describes Indigenous perceptions of the Skyworld flora and draws out major ethnobotanical themes from the corpus of ethnoastronomical records garnered from a diverse range of Australian Aboriginal cultures. It investigates how Indigenous perceptions of the flora are interwoven with Aboriginal traditions concerning the heavens, and provides examples of how the study of ethnoastronomy can provide insights into the Indigenous use and perception of plants. Keywords: ethnoastronomy, cultural astronomy, ethnobotany, aesthetics, Aboriginal Australians 1 INTRODUCTION raw materials for food, medicine and artefact- How people conceive and experience physical making.

Pulsating Components in Binary and Multiple Stellar Systems---A
Research in Astron. & Astrophys. Vol.15 (2015) No.?, 000–000 (Last modified: — December 6, 2014; 10:26 ) Research in Astronomy and Astrophysics Pulsating Components in Binary and Multiple Stellar Systems — A Catalog of Oscillating Binaries ∗ A.-Y. Zhou National Astronomical Observatories, Chinese Academy of Sciences, Beijing 100012, China; [email protected] Abstract We present an up-to-date catalog of pulsating binaries, i.e. the binary and multiple stellar systems containing pulsating components, along with a statistics on them. Compared to the earlier compilation by Soydugan et al.(2006a) of 25 δ Scuti-type ‘oscillating Algol-type eclipsing binaries’ (oEA), the recent col- lection of 74 oEA by Liakos et al.(2012), and the collection of Cepheids in binaries by Szabados (2003a), the numbers and types of pulsating variables in binaries are now extended. The total numbers of pulsating binary/multiple stellar systems have increased to be 515 as of 2014 October 26, among which 262+ are oscillating eclipsing binaries and the oEA containing δ Scuti componentsare updated to be 96. The catalog is intended to be a collection of various pulsating binary stars across the Hertzsprung-Russell diagram. We reviewed the open questions, advances and prospects connecting pulsation/oscillation and binarity. The observational implication of binary systems with pulsating components, to stellar evolution theories is also addressed. In addition, we have searched the Simbad database for candidate pulsating binaries. As a result, 322 candidates were extracted. Furthermore, a brief statistics on Algol-type eclipsing binaries (EA) based on the existing catalogs is given. We got 5315 EA, of which there are 904 EA with spectral types A and F. -

Clusters Nebulae & Galaxies
CLUSTERS, NEBULAE & GALAXIES A NOVICE OBSERVER’S HANDBOOK By: Prof. P. N. Shankar PREFACE In the normal course of events, an amateur who builds or acquires a telescope will use it initially to observe the Moon and the planets. After the thrill of seeing the craters of the Moon, the Galilean moons of Jupiter and its bands, and the rings of Saturn he(*) is usually at a loss as to what to do next; Mars and Venus are usually disappointing as are the stars (they don’t look any bigger!). If the telescope had good resolution one could observe binaries, but alas, this is often not the case. Moreover, at this stage, the amateur is unlikely to be willing to do serious work on variable stars or on planetary observations. What can he do with his telescope that will rekindle his interest and prepare him for serious work? I believe that there is little better for him to do than hunt for the Messier objects; this book is meant as a guide in this exciting adventure. While this book is primarily a guide to the Messier objects, a few other easy clusters and nebulae have also been included. I have tried, while writing this handbook, to keep in mind the difficulties faced by a beginner. Even if one has good star maps, such as those in Norton’s Star Atlas, a beginner often has difficulty in locating some of the Messier objects because he does not know what he is expected to see! A cluster like M29 is a little difficult because it is a sparse cluster in a rich field; M97 is nominally brighter than M76, another planetary, but is more difficult to see; M33 is an approximately 6th magnitude galaxy but is far more difficult than many 9th magnitude galaxies.
