Plot summary
Simeon Weill, a physicist, experiments with time travel and travels back to New York City in 1925, where he meets Hugo Gernsback, a science fiction author and Weill's hero.

Although only given a few minutes sitting with Gernsback on a park bench, he manages to convey to the author some of the scientific developments to come in the next fifty years. Just before being transported back to 1976, he suggests that Gernsback's proposed science fiction magazine be titled Amazing Stories.
