[художник Федотов]

In a German school teacher gave the children of other problems for Example..., 1+2+3+...+498+499=? One student immediately, in my mind, gave the answer...Apparently he was too lazy to fold, as did all...Later in the story he came as the great mathematician, opening for science formula for the sum of arithmetic progression in childhood...It's one of the few times in history when the Prodigy have not lost their opportunities in adulthood...
