Kort historia är "Förstå" av Ted Chiang. Från Wikipedia:
The story follows a man who is given an experimental drug to heal brain damage caused by anoxia after he nearly drowns. The drug regenerates his damaged neurons and has the unintended side effect of exponentially improving his intellect and motor skills. As he gets smarter and smarter, he is pursued by several government agencies and eventually receives a message from—and then enters into conflict with—another super-intelligent test subject.
Jag rekommenderar starkt Chiangs novellsamling som innehåller denna historia och annat briljant arbete, inklusive den korta historien som 2016-filmen Ankomst är baserad på.
