As part of the Researchers' Night, on the 24th of September, 2021 we will invite science and research enthusiasts to an interactive exhibition called Pendulum Night. A representative publication entitled Mappæ Comitatuum Transylvaniæ by Bartos-Elekes Zsombor will be presented, and Annamária Csókási will give a lecture with the title Cultures torn apart – Cultural damage assessment with military technology in Nagorno Karabakh. All visitors are welcome!
Lectures (Venue: Ballroom)
16.00-18.00 Book presentation and round table discussion in connection with Bartos-Elekes Zsombor's publication Mappæ Comitatuum Transylvaniæ
The book was published as a result of the successful cooperation between the University Library and Archives of the Eötvös Loránd University and the Cluj-Napoca School Foundation Publishing House. The work, published under the title Mappæ Comitatuum Transylvaniae, is in the 91st volume of the outstanding collection of the Jesuit scholar Gábor Hevenesi, preserved in our library. This volume is the first to publish 18 Transylvanian (and Partium) map sheets, which are much more detailed than previous cartographs, so their source value is extremely significant. The accompanying study on the structure, content and background of the maps is available in three languages (Hungarian, Romanian, English), which is completed by a precisely compiled index. The book also provides an insight into the unique collection of our library.
8.00-19.00 Annamária Csókási Cultures torn apart – Cultural damage assessment with military technology in Nagorno Karabakh (lecture in Hungarian)
19.00-20.00 Annamária Csókási Cultures torn apart – Cultural damage assessment with military technology in Nagorno Karabakh (lecture in English)
The lecture Cultures torn apart – Cultural damage assessment with military technology in Nagorno Karabakh is about the damaged cultural treasures of Nagrno Karabakh and the difficulty of the restoration programs. By rolling up the Hungarian and also the Iranian perspective, we get the exact answer on why is this area really a grey zone for the European cultural policy.
Guided tours at the Eötvös Exhibition (Venue: Eötvös Exhibition)
17.00-18.00 The Night of the Pendulum – Guided tour of the Eötvös exhibition
18.00-19.00 The Night of the Pendulum – Guided tour of the Eötvös exhibition
19.00-20.00 The Night of the Pendulum – Guided tour of the Eötvös exhibition
The physicist, Loránd Eötvös (1848–1919) focused on gravitational research from the 1880s, and in the following decades he carried out his experiments on the mutual attraction of bodies and the observation of the force of gravity on earth. Compared to previous similar tools, Eötvös has designed and continuously developed a much more sensitive and precise tool with the help of his colleagues. With Eötvös pendulums manufactured at Nándor Süss's fine mechanics workshop (former predecessor of MOM, Hungarian Optical Works), Loránd Eötvös showed the identity of heavy and helpless masses (one of the foundations of Einstein's general theory of relativity) with unimaginable accuracy and measured the change in the Earth's gravitational field.
He obtained his results on the basis of data gained from field measurements. Eötvös and his team examined areas which seemed interesting from the point of view of changes and anomalies of gravitation originating from the presence of rocks of different density under the surface. In thirty years, 1420 different parts of Europe were measured with the pendulum – from Transylvania to Italy.
One of the early versions of the Eötvös pendulum, the “Paris pendulum” made in 1898, was exhibited in the interactive exhibition The Enchantment of Precision – The Life and Work of Loránd Eötvös. After closing our library, when the street is already quiet, it is worth watching the pendulum during operation. Join us, let's take a look at the sensitive instrument together on Researchers' Night!
