Marina Rieznik, professeure d'histoire des sciences à l'Universidad Nacional de Quilmes (Buenos Aires, Argentine) et membre du Conicet, sera à Nancy le 4 novembre. Dans le cadre du projet ANR BDL 1795-1932, elle fera un séminaire qui porte sur : "Venus Peepers. Bureau des longitudes, popular astronomy and the foundation of the La Plata's Observatory" dont vous trouverez le résumé ci-dessous. Le séminaire sera en anglais et aura lieu de 10h30 à 12h30 à la Maison des sciences de l'Homme Lorraine (salle 326).
Thème du séminaire : In 1882, in Argentina, the governor of Buenos Aires province and members of France’s Bureau of Longitudes fostered one of the international missions that were observing the transit of Venus across the sun. The instruments they used would serve in the founding of an observatory in La Plata. In this talk I stress the interrelationships between the foundation of that observatory and the popular spreading of news about the transit of Venus. The interest is to get into the historical construction of the assumption that claims that there is a clear limit between amateur records and scientific registry. Also we will show that the competitions between observatories were involved in the construction of that limit.
