The Black Codes, sometimes called the Black Laws, were laws which governed the conduct of African Americans (both free and freedmen).In 1832, James Kent wrote that "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free colored persons of African blood; and in no part of the country do the latter, in point of fact ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
Forsyth–Edwards Notation ( FEN) is a standard notation for describing a particular board position of a chess game. The purpose of FEN is to provide all the necessary information to restart a game from a particular position. FEN is based on a system developed by Scottish newspaper journalist David Forsyth. His system became popular in the 19th ...
A black string is a higher dimensional (D>4) generalization of a black hole in which the event horizon is topologically equivalent to S 2 × S 1 and spacetime is asymptotically M d−1 × S 1. Perturbations of black string solutions were found to be unstable for L (the length around S 1 ) greater than some threshold L ′.
A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [ 1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859 ...

Cosmic string. Cosmic strings are hypothetical 1-dimensional topological defects which may have formed during a symmetry-breaking phase transition in the early universe when the topology of the vacuum manifold associated to this symmetry breaking was not simply connected. Their existence was first contemplated by the theoretical physicist Tom ...
