Once again, IGCE in cooperation with the Latvian Association of Young Scientists and the Latvian National Library offered the incredible opportunity to get acquainted with science for all who were interested in it. This year’s theme was “Crystals”. During the event, everyone had the opportunity to get knowledgeable about a selection of books from the library’s collection on crystals. Moreover, they were able to catch a glimpse of the exhibition on crystals and listen to the lectures on the correlative topic, followed by the set of experiments.
