In his seminal 1967 book, The Codebreakers, Kahn marveled at the ability of individuals to discover incredibly complex, albeit nonexistent codes, which he described as “classic instances of wishful thinking” caused by “an overactive cryptanalytic gland.”
“A hidden code can be found almost anywhere because people are adept at recognizing and creating patterns,” says Klaus Schmeh, a computer scientist specializing in encryption technology. Schmeh has updated Kahn’s research, documenting dozens of bogus or dubious cryptograms. Some are more than a century old, but still making the rounds in books and on websites; others are more recent, such as a claim that all barcodes contain the satanic number, 666. […]
Generations of investigators have been convinced that—through divine revelation or the assistance of extraterrestrials—the builders of the Great Pyramid embedded the sum total of scientific knowledge within the dimensions of the structure. Fringe pyramidologists persist in their claims despite a 1992 effort to debunk them by Dutch astrophysicist Cornelis de Jager, who demonstrated the dimensions of any object can be manipulated to yield a desired outcome; he derived the speed of light and the distance between the Earth and Sun from his measurements of a bicycle.
