Originally published by Sá da Costa between 1979 and 1985, Cadernos de Iniciação Científica was a science communication effort aimed at children 9-15. It was edited by scientist, poet, and towering figure of Portuguese twentieth-century science communication Rómulo de Carvalho, whose literary nom de plume António Gedeão he also used to sign some of the covers he designed for his own science books - see artifacts História dos Isótopos and História da Energia Nuclear.

Carlos Fiolhais, professor of Physics at the University of Coimbra and one of the greatest Portuguese science communicators after Carvalho called Cadernos de Iniciação Científica «profoundly original little books» and of «an uncommon graphic quality and good taste»¹.
