The Faculty of Mathematics and Computer Science organizes on May 17 a thematic visit to the Astronomical Observatory for Ukrainian refugee children from Cluj-Napoca. This visit is possible with the support of the Alma Mater Napocensis Foundation and the O Masă Caldă Association. We are therefore waiting with open arms for approximately 40 Ukrainian children to participate in this event, on which the researcher Liviu Mircea from the Astronomical Observatory will reveal to the guests the secrets of the universe.
