Kryptos
''Kryptos'' is a sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the four encrypted messages it bears. Of these four messages, the first three have been solved, while the fourth message remains one of the most famous unsolved codes in the world. The sculpture continues to be of interest to cryptanalysts, both amateur and professional, who are attempting to decipher the fourth passage. The artist has so far given four clues to this passage. Description The main part of the sculpture is located in the northwest corner of the New Headquarters Building courtyard, outside of the Agency's cafeteria. The sculpture comprises four large copper plates with other elements consisting of water, wood, plants, red and green granite, white quartz, and petrified wood. The most prominent feature is a large vertical S-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Intelligence Agency
The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and performing covert actions. As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States.

Reflecting Pool
A reflecting pool, also called a reflection pool, is a water feature found in gardens, parks, and memorial sites. It usually consists of a shallow pool of water, undisturbed by fountain jets, for a reflective surface. Design Reflecting pools are often designed with the outer basin floor at the rim slightly deeper than the central area to suppress wave formation. They can be as small as a bird bath to as large as a major civic element. Their origins are from ancient Persian gardens.

Studies In Intelligence
''Studies in Intelligence'' is a quarterly peer-reviewed academic journal on intelligence that is published by the Center for the Study of Intelligence, a group within the United States Central Intelligence Agency. It contains both classified and unclassified articles on the methodology and history of the field of intelligence gathering. The journal was established by Sherman Kent in 1955. According to Kent, intelligence "has developed a recognized methodology; it has developed a vocabulary; it has developed a body of theory and doctrine; it has elaborate and refined techniques. It now has a large professional following. What it lacks is a literature.... The most important service that such a literature performs is the permanent recording of our new ideas and experiences." Copies of unclassified and declassified articles from ''Studies in Intelligence'' are held at the National Archives' College Park, Maryland College Park is a city in Prince George's County, Maryland, United ...

Computer Scientist
A computer scientist is a person who is trained in the academic study of computer science. Computer scientists typically work on the theoretical side of computation, as opposed to the hardware side on which computer engineers mainly focus (although there is overlap). Although computer scientists can also focus their work and research on specific areas (such as algorithm and data structure development and design, software engineering, information theory, database theory, computational complexity theory, numerical analysis, programming language theory, computer graphics, and computer vision), their foundation is the theoretical study of computing from which these other fields derive. A primary goal of computer scientists is to develop or validate models, often mathematical, to describe the properties of computational systems (processors, programs, computers interacting with people, computers interacting with other computers, etc.) with an overall objective of discovering des ...
