The scatter of electrical lighting has all but obliterated the starry skies that we gaze into with the same wonder as that in which philosophy begins. There is an organized resistance movement that merits everyone's support. But another front in this long war has opened with the the arrival of technological means to project three dimensional images into the atmosphere, as reported in The New Scientist (Feb. 27), "3D Plasma Shapes Created in Thin Air." A few years ago, there was a scheme to project advertising logos onto the moon. It fell apart (or did it?) and maybe this one will as well. For now, anyway, the eye can find Sirius by tracking left from Orion's belt, without having to cut through Coca-Cola. (And, hey, we can always wonder at the moral law within us!)
