more when he had first heard the alien mention "test". He had expected some complex instrument, something new to Terra and her colonies. Something involving complex and perhaps unknown principles of an alien technology. Something appropriate to the strange metal craft that traveled so very fast. Or perhaps a paradox. A thing that could not be constructed without exploding, like a lattice of U235 of exactly critical size. Or an instrument that must be assembled in an impossible sequence, like a clock with a complete, single-pieced outer shell. Or a part of a thing that could be "corrected" only if the whole thing were visualized, constructed, and tested.

All there for you to read...." By Christ, thought Harrison. Here was an aspect of the concept, sword, he had not considered. Morphological thinking required that all aspects of a concept be explored, all plotted against all
