Organised by Pau Amaro Seoane (UPV), Amaya Ofelia Casanova, Fernando Guzmán (InSTEC), Leonel Morejón and Stamatis Vretinaris at the Instituto Superior de Tecnologías y Ciencias Aplicadas (InSTEC) de la Universidad de La Habana, from 5-18 March 2023.

The idea is to broaden the knowledge of topics in astrophysics, general relativity and fundamental physics that Cuban students of the InSTEC and other research institutes of Cuba as a way to choose their future interests, as well as to establish new collaborations between Cuban and non-Cuban researchers.

The talks will not be classical talks, but “constantly-interrupted-ones“, in the sense that the speakers will have to address as many questions as the students see fit to ask to understand the topic being presented, instead of just hearing a talk. There is a difference.
