The physicists Xavier Obradors, ICMAB Director, and Ignasi Ribas, Director of the Institute of Space Studies of Catalonia (Institut d'Estudis Espacials de Catalunya, IEEC), gave a joint lecture for the celebration of the 90th anniversary of the Institute "Lluís de Peguera" in Manresa (26 October 2017), in which they both went as students.
