            Another example is Herschel's discovery of Uranus. He certainly wasn't looking
    for it. But he was engaged in a systematic survey of the sky & if he hadn't found it
    one night, he would have on the next. It was, he said later, it's turn to be
            & of course others before Herschel had seen Uranus but hadn't realized that it
    was anything more than another star. One has to follow up accidental discoveries for
    them to have any value. A number of physicists between ~1925 & 1956 (including one of
    my former profs at Johns Hopkins) got peculiar results with electrons that could have
    tipped them off to the fact that parity wasn't conserved in weak interactions, but
    nobody pursued the idea until Lee & Yang suggested it theoretically.
