Difference (from prior major revision) (minor diff)

Changed: 1c1
Lincos (an abbreviation of the latin phrase "lingua cosmica") is an [artifical language]? first described in 1960 by [Hans Freudenthal]? and described in his book LINCOS: Design of a Language for Cosmic Intercourse. It is a language designed to be understandable by any possible intelligent alien life form, for use in interstellar radio transmissions.

No actual transmissions have been made using Lincos; it remains largely a theoretical exercise.

An example of Lincos from section 3 of Freudenthal's book, showing one individual asking another individual questions:












Lincos textMeaning
Ha Inq Hb ?x 2x=5Ha says to Hb: What is the x such that 2x=5?
Hb Inq Ha 5/2Hb says to Ha: 5/2.
Ha Inq Hb BenHa says to Hb: Good.
Ha Inq Hb ?x 4x=10Ha says to Hb: What is the x such that 4x=10?
Hb Inq Ha 10/4Hb says to Ha: 10/4.
Ha Inq Hb MalHa says to Hb: Bad.
Hb Inq Ha 1/4Hb says to Ha: 1/4.
Ha Inq Hb MalHa says to Hb: Bad.
Hb Inq Ha 5/2Hb says to Ha: 5/2.
Ha Inq Hb BenHa says to Hb: Good.

Note the difference between "good" and "bad" and "true" and "false"; 10/4 is a true answer to the question, but it isn't what Ha wanted because Hb didn't reduce the fraction to its lowest terms.

Another example, showing meta-conversation:

Ha Inq Hb ?x 4x=10Ha says to Hb: What is the x such that 4x=10?
Hb Inq Hc ?y y Inq Hb ?x 4x=10Hb says to Hc: Who asked me for the x such that 4x=10?
Hc Inq Hb HaHc says to Hb: Ha.
