The Girls' Day is a nationwide activity to arouse the interest of girls to field of works, which are typically staffed by men. The Faculty of Mathematics and Physics offers four workshops, one in mathematics and three in physics. The girls are invited to simulate physicphenomena, do geometric handicrafts and experiments in a physics lab.
