« Siempre le he dado una gran importancia a la forma en que se configura y realiza un experimento... El experimento debe configurarse para abrir tantas ventanas como sea posible a lo imprevisto.
[I have always attached great importance to the manneer in wich an experiment is set up and conducted... The experiment should be set up to open as many windows as possible on to the unforeseen]. »
Frédéric Joliot
