单选题 . ①According to von Kárman, a scientist seeks to understand what is; an engineer, to create what never. ②But dichotomies are seldom clear-cut. ③When a scientist proposes a truly new hypothesis about, say, the origin of the universe, that hypothesis "never was" prior to its articulation by that scientist. ④Einstein, certainly a prototypical scientist, took that view, criticizing physicist and philosopher Ernst Mach for having "thought that somehow theories arise by means of discovery rather than invention." ⑤Science historian Thomas P. Hughes notes that to Einstein, invention was the manipulation not only of things but also of concepts. ⑥Einstein believed that an artifact was a materialized concept and that a hard-and-fast line between technology and science simply did not exist.
