In 1854, the British mathematician George Boole presented the idea of a universe the elements of which could be understood in terms of the logic of absence and presence: 0 and 1, all and nothing - the foundation of binary code. The Boolean digits 0 and 1 do not designate a quantity. In the Boolean world, x times x always equals x; all and nothing meet in the formula x = xn. As everything becomes digitized, God the clockmaker is replaced by God the programmer. This book - described by its authors as a theology for the digital world - explores meaning in a digital age of infinite replication, in a world that has dissolved into information and achieved immortality by turning into a pure sign. sakriti opis
