    Identifying seasonal stars in Kaurna astronomical traditions

    Full text link
    Early ethnographers and missionaries recorded Aboriginal languages and oral traditions across Australia. Their general lack of astronomical training resulted in misidentifications, transcription errors, and omissions in these records. Additionally, many of these early records are fragmented. In western Victoria and southeast South Australia, many astronomical traditions were recorded, but curiously, some of the brightest stars in the sky were omitted. Scholars claimed these stars did not feature in Aboriginal traditions. This under-representation continues to be repeated in the literature, but current research shows that some of these stars may in fact feature in Aboriginal traditions and could be seasonal calendar markers. This paper uses established techniques in cultural astronomy to identify seasonal stars in the traditions of the Kaurna Aboriginal people of the Adelaide Plains, South Australia.Comment: Journal of Astronomical History and Heritage, Vol. 18(1), Preprin

    Meteoritics and cosmology among the Aboriginal cultures of Central Australia

    The night sky played an important role in the social structure, oral traditions, and cosmology of the Arrernte and Luritja Aboriginal cultures of Central Australia. A component of this cosmology relates to meteors, meteorites, and impact craters. This paper discusses the role of meteoritic phenomena in Arrernte and Luritja cosmology, showing not only that these groups incorporated this phenomenon in their cultural traditions, but that their oral traditions regarding the relationship between meteors, meteorites and impact structures suggests the Arrernte and Luritja understood that they are directly related.Comment: Journal of Cosmology, Volume 13, pp. 3743-3753 (2011

    Marginal revenue product and salaries: Moneyball redux

    Scully (1974) used a two equation regression model to estimate a baseball player’s salary to compare to the actual salary the player earned in order to determine if a player is paid his net marginal revenue product. We replicate the spirit of that paper, but introduce several useful innovations to estimate net marginal revenue products for a large sample of free-agent baseball players. Our results suggest that the highest paid free agents are overpaid, while all other free agents are underpaid or paid appropriately. We found no evidence for the notion that some clubs may be more adept at finding “bargain” free agents.net marginal revenue product; free agents; baseball

    We revisit an earlier calculation of the decay H\to e\,\bar{e}\ga using the recently reported mass value of the Higgs boson candidate observed in the ATLAS and CMS experiments together with cuts that are appropriate for experimental analyzes.Comment: 4 pages, 5 figure

    "Bridging the Gap" through Australian Cultural Astronomy

    For more than 50,000 years, Indigenous Australians have incorporated celestial events into their oral traditions and used the motions of celestial bodies for navigation, time-keeping, food economics, and social structure. In this paper, we explore the ways in which Aboriginal people made careful observations of the sky, measurements of celestial bodies, and incorporated astronomical events into complex oral traditions by searching for written records of time-keeping using celestial bodies, the use of rising and setting stars as indicators of special events, recorded observations of variable stars, the solar cycle, and lunar phases (including ocean tides and eclipses) in oral tradition, as well as astronomical measurements of the equinox, solstice, and cardinal points.Comment: Proceedings of IAU Symposium 278, Oxford IX International Symposium on Archaeoastronomy, International Society for Archaeoastronomy & Astronomy in Culture (ISAAC), held in Lima, Peru, 5-9 January 2011. 9 pages, 4 images, 1 table (Accepted
