The contents of the Greek magazine "Physicos Cosmos" include science popularization, teaching proposals, and issues of educational concern. The magazine is addressed to teachers of physics and, consequently, to grammar-school pupils/students. Its articles ranged, in general, from short texts taken from physical sciences to more specialized articles. During the period under consideration (1975-1977), i.e., after the fall (1974) of the military government (1967-1974) and the outset of the educational reform, the magazine's subjects changed, comprising interdisciplinary proposals in relation to the philosophy of physical and natural sciences, their history, their social usefulness, and their connections with non-scientific culture. Some new approaches concerned particularly school geography as a multidisciplinary field.
