  3. Kryptos - Wikipedia

    en.wikipedia.org/wiki/Kryptos

    The dust jacket of the US version of Dan Brown's 2003 novel The Da Vinci Code contains two references to Kryptos—one on the back cover (coordinates printed light red on dark red, vertically next to the blurbs) is a reference to the coordinates mentioned in the plaintext of passage 2, except the degree digit is off by one. When Brown and his ...

    The partially decomposed body of Ricky McCormick was discovered in a field in St. Charles County, Missouri on June 30, 1999. Sheriffs found two garbled hand-written notes – apparently written in secret code – in the victim's pockets, and these were handed over to the FBI for further investigation. Attempts by the FBI's Cryptanalysis and ...

    The Nirenberg and Matthaei experiment was a scientific experiment performed in May 1961 by Marshall W. Nirenberg and his post-doctoral fellow, J. Heinrich Matthaei, at the National Institutes of Health (NIH). The experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymers to translate specific ...

  6. Genetic code - Wikipedia

    en.wikipedia.org/wiki/Genetic_code

    The genetic code is a key part of the history of life, according to one version of which self-replicating RNA molecules preceded life as we know it. This is the RNA world hypothesis . Under this hypothesis, any model for the emergence of the genetic code is intimately related to a model of the transfer from ribozymes (RNA enzymes) to proteins ...

  8. Caesar cipher - Wikipedia

    en.wikipedia.org/wiki/Caesar_cipher

    In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet .

  9. History of cryptography - Wikipedia

    en.wikipedia.org/wiki/History_of_cryptography

    History of cryptography. Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In the early 20th century, the invention ...
