Universal logic gates

Charles Sanders Peirce (winter of 1880–81) showed that NOR gates abandoned (or alternatively NAND gates alone) can be acclimated to carbon the functions of all the added argumentation gates, but his assignment on it was abstruse until 1933.2 The aboriginal appear affidavit was by Henry M. Sheffer in 1913, so the NAND analytic operation is sometimes alleged Sheffer stroke; the analytic NOR is sometimes alleged Peirce's arrow.3 Consequently, these gates are sometimes alleged accepted argumentation gates.4
