    I was reminded of Space Cadet, too. Reading that passage again (for the first time in fifty years), I see that there were at least two tests with hidden purposes. One is a simple task where the test-taker could easily cheat if he…

    …more prescient bit of science fiction. Bradbury knew how people worked and what we'd try to make. While not a start-to-finish prophecy like "The Murderer", from Wikipedia's article on Robert Heinlein's Space Cadet: >The novel contains an early description of a mobile phone: >>Matt dug a candy bar out of his pouch, split it and gave half to Jarman, who accepted it gratefully. "You're a pal, Matt, I've been living…

    This conversation, while interesting, is no longer connected with Heinlein and increasingly farther from something I can meaningful contribute to. To bring it back to Heinlein, a quote from "Space Cadet": > The staple recreation in the Randolph, as it is in all boarding schools, was the bull session. The talk ranged through every possible subject and was kept spiced by Arensa's original and usually…

    The mission of the overall site: "Your imagination has been captured by the roaring rockets from Heinlein's SPACE CADET or the Polaris from TOM CORBETT, SPACE CADET. But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers? "This document gives some hints and equations…

    IIRC, it started out as a reimagining of Space Cadet by Heinlein but instead of the young it was with the old. After the first book, he then goes to explore all the questions that it brought up. The question of identity (to me) seems like the most reoccurring…
