Come and learn the rules of fundamental particle physics as if they were the rules of a card game! With the game TUTTI QUANTUM - developed by the Department of Theoretical Physics in collaboration with the publisher Helvetiq - you can challenge the EPFL professors and if you win, receive a pack of these cards yourself. In parallel: the fundamental physics circus! Come and ask your questions about the universe, matter, light, stars and atoms... and discover that knowing is not knowing everything. Children are especially welcome!
