EspañolLINCOS (LANGUAGE)
'Lincos' (an abbreviation of the Latin phrase ''lingua cosmica'') is an artificial language first described in 1960 by Dr. Hans Freudenthal in his book ''Lincos: Design of a Language for Cosmic Intercourse, Part 1''. It is a language designed to be understandable by any possible intelligent extraterrestrial life form, for use in interstellar radio transmissions. Freudenthal considered that such a language should be easily understood by beings not acquainted with any Earthling syntax or language. Lincos was designed to be capable of encapsulating "the whole bulk of our knowledge."
The Lincos "dictionary," intended to be transmitted first before any additional messages, begins with a simple pattern of pulses intended to establish the terminology for natural numbers and basic arithmetic (addition, subtraction, multiplication and division) in base two. The concepts of equality, comparison, variables and constants are also illustrated by a series of examples, and then finally propositional logic, set theory and first-order logic. The next section of the Lincos dictionary establishes vocabulary for describing time, introducing means for measuring durations, referring to moments in time, and talking about past and future events. The third section is perhaps the most complex, and attempts to convey the concepts and language necessary to describe behavior and conversation between individuals. It uses examples to introduce actors speaking to each other, asking questions, disapproving, quoting other people, knowing and wanting things, promising, and playing. Finally, the fourth section describes the concepts and language relating to mass, space, and motion. This last section goes so far as to describe physical features of human beings and of the Solar system.
A second book was planned but never written that would have added four more sections to the dictionary: "Matter," "Earth," "Life" and "Behavior 2." Other researchers have since extended the language somewhat on their own (see, for example, CosmicOS).
No actual transmissions have been made using Lincos; it remains largely a theoretical exercise in Communication with Extraterrestrial Intelligence.
An example of Lincos from section 3 of Freudenthal's book, showing one individual asking another individual questions:
Note the difference between "good" and "bad" as compared to "true" and "false"; 10/4 is a true answer to the question, so ''Ver'' ("true") would be a valid response, but since it wasn't reduced to lowest terms, it wasn't what Hb wanted and so he responded ''Mal'' ("bad") instead.
Another example, showing meta-conversation:
In the motion picture ''Contact'', SETI astronomers receive a radio transmission from space that has a Lincos-like dictionary embedded in the message.

Concepts and range
The Lincos "dictionary," intended to be transmitted first before any additional messages, begins with a simple pattern of pulses intended to establish the terminology for natural numbers and basic arithmetic (addition, subtraction, multiplication and division) in base two. The concepts of equality, comparison, variables and constants are also illustrated by a series of examples, and then finally propositional logic, set theory and first-order logic. The next section of the Lincos dictionary establishes vocabulary for describing time, introducing means for measuring durations, referring to moments in time, and talking about past and future events.

Examples
An example of Lincos from section 3 of Freudenthal's book, showing one individual asking another individual questions:
| Lincos text | Meaning |
|---|---|
| ''Ha'' Inq ''Hb'' ?''x'' 2''x''=5 | Ha says to Hb: What is the x such that 2x=5? |
| ''Hb'' Inq ''Ha'' 5/2 | Hb says to Ha: 5/2. |
| ''Ha'' Inq ''Hb'' Ben | Ha says to Hb: Good. |
| ''Ha'' Inq ''Hb'' ?''x'' 4''x''=10 | Ha says to Hb: What is the x such that 4x=10? |
| ''Hb'' Inq ''Ha'' 10/4 | Hb says to Ha: 10/4. |
| ''Ha'' Inq ''Hb'' Mal | Ha says to Hb: Bad. |
| ''Hb'' Inq ''Ha'' 1/4 | Hb says to Ha: 1/4. |
| ''Ha'' Inq ''Hb'' Mal | Ha says to Hb: Bad. |
| ''Hb'' Inq ''Ha'' 5/2 | Hb says to Ha: 5/2. |
| ''Ha'' Inq ''Hb'' Ben | Ha says to Hb: Good. |
Note the difference between "good" and "bad" as compared to "true" and "false"; 10/4 is a true answer to the question, so ''Ver'' ("true") would be a valid response, but since it wasn't reduced to lowest terms, it wasn't what Hb wanted and so he responded ''Mal'' ("bad") instead.
Another example, showing meta-conversation:
| Lincos text | Meaning |
|---|---|
| ''Ha'' Inq ''Hb'' ?''x'' 4''x''=10 | Ha says to Hb: What is the x such that 4x=10? |
| ''Hb'' Inq ''Hc'' ?''y'' ''y'' Inq ''Hb'' ?''x'' 4''x''=10 | Hb says to Hc: Who asked me for the x such that 4x=10? |
| ''Hc'' Inq ''Hb'' ''Ha'' | Hc says to Hb: Ha. |

In the motion picture ''Contact'', SETI astronomers receive a radio transmission from space that has a Lincos-like dictionary embedded in the message.
