Error Detection and Correction - History

History

The most famous early systematic use of error detection was by Jewish scribes in the precise copying of the Jewish bible, beginning before Christ. An emphasis on minute details of words and spellings evolved into the idea of a perfect text in 135 CE, and with it increasingly forceful strictures that a deviation in even a single letter would make a Torah scroll invalid. The scribes used methods such as summing the number of words per line and per page (Numerical Masorah), and checking the middle paragraph, word and letter against the original. The page was thrown out if a single mistake was found, and three mistakes on a single page would result in the entire manuscript being destroyed (the equivalent of retransmission on a telecommunications channel). The effectiveness of their methods was verified by the accuracy of copying through the centuries demonstrated by discovery of the Dead Sea Scrolls in 1947-1956, dating from c.150 BCE-75 CE.

Famous quotes containing the word history:

    They are a sort of post-house,where the Fates
    Change horses, making history change its tune,
    Then spur away o’er empires and o’er states,
    Leaving at last not much besides chronology,
    Excepting the post-obits of theology.
    George Gordon Noel Byron (1788–1824)

    To summarize the contentions of this paper then. Firstly, the phrase ‘the meaning of a word’ is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, ‘being a part of the meaning of’ and ‘having the same meaning.’ On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.
    —J.L. (John Langshaw)

    It’s nice to be a part of history but people should get it right. I may not be perfect, but I’m bloody close.
