Traditionally, as every semester, the Institute of Physics organized experimental demonstrations as part of Orientation Week - an event aimed at Erasmus+ students who have undertaken studies and internships at our university. This semester, we are hosting students from Spain, Greece, Italy, France, Serbia, Turkey, Bosnia and Herzegovina, Lithuania, and Romania, among others. In addition to the demonstrations, our guests had the opportunity to attend presentations by Prof. Sylwia Kondej from the Institute of Physics and Prof. Wojciech Lewandowski from the Institute of Astronomy.
