Abstract
We focus on artifact which is phenotype of a sort of genes “technological knowledge”. And we make clear the difference between science communication and technological communication mediated by artifact. Two points are essential, i. e. artifact and engineer. And then four key words are needed, requirement specification, inspection, technical standards, and manufacturing industry. We conclude that technological communication mediated by artifact is different from science communication. The point is the strangeness of “mediated by artifact”.
