Audio-visual for physics INTER NAVEX 74
INTER NAVEX annually provides the world's largest audio-visual exhibition and conference, this year having well over a hundred stands, numerous film shows and a major daily programme of conference sessions. From the many new items of hardware and software available this year, the author selects those of most interest to the physics teacher. On the whole the theme is hardware-as indeed was that of the majority of exhibits-but particularly noteworthy software companies are mentioned too.
From our ongoing survey to study the post-nova population we present details on the four objects V728 Sco, AR Cir, V972 Oph and X Cir.
