This is the first page that forms the 'quanta' of dots into a wave form. It comes at a point (see previous post) where the Radio evokes the presence of the universe as a real place, as a place that can seem both distant and present, right there behind the speaker grille.
Amongst the chaos (the scribbled spirals and 'zips' of random passages and collisions in the 'cloud chamber' in the background of the image) the clear pattern of a wave stands out, and we can fasten our attention on it. Our image of presence fastens on to the coherence of something that is, in itself perhaps illusory, a wave built out of the happenstance qualities of the universe.
