Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Yet the visual record is made by the movie with no recently discovered magic. The accomplishment consists in uniting two facts with which we have been familiar for a long time. Photography has used light to record images on sensitive sur faces since the days of Daguerre, more than a hundred years ago, human beings have, since the dawn of their experience, had what scientists call persistence of vision. If we look at something bright and if it is quickly removed from view, it will seem to hold over for a brief flash of time. This flash is enough to give us motion pictures, which are only still pic tures projected on a screen fast enough, one after another, to create what appears to be continuous motion.
