Editing Error detection and correction (section)

== History ==
In classical antiquity, [[copyist]]s of the [[Hebrew Bible]] were paid for their work according to the number of [[Wiktionary:stich|stich]]s (lines of verse). As the prose books of the Bible were hardly ever written in stichs, the copyists, in order to estimate the amount of work, had to count the letters.<ref name="Jewish">{{cite encyclopedia |url=http://www.jewishencyclopedia.com/articles/10465-masorah |encyclopedia=Jewish Encyclopedia |article=Masorah}}</ref> This also helped ensure accuracy in the transmission of the text with the production of subsequent copies.<ref>{{cite book |last1=Pratico |first1=Gary D. |last2=Pelt |first2=Miles V.

The modern development of [[error correction code]]s is credited to [[Richard Hamming]] in 1947.<ref name=Thompson>{{citation|first=Thomas M.|last=Thompson|title=From Error-Correcting Codes through Sphere Packings to Simple Groups|publisher=The Mathematical Association of America|year=1983|series=The Carus Mathematical Monographs (#21)|isbn=0-88385-023-0|page=vii}}</ref> A description of [[Hamming's code]] appeared in [[Claude Shannon]]'s ''A Mathematical Theory of Communication''<ref>{{citation|first=C.E.|last=Shannon|title=A Mathematical Theory of Communication|journal=Bell System Technical Journal|volume=27|issue=3|pages=379–423|year=1948|doi=10.1002/j.1538-7305.1948.tb01338.x|pmid=9230594|hdl=10338.dmlcz/101429|hdl-access=free}}</ref> and was quickly generalized by [[Marcel J.
