Communication with Extraterrestrial Intelligence #6

This first page of the Cosmic Call 1999 message, shown above, involves only numbers Cosmic Call Physicists are announcing today that they have designed a message to be broadcast in the direction of nearby stars in order to search for extra-terrestrial intelligence. This project is being presented by Dr. Yvan Dutil and Stephane Dumas from the Defence Research Establishment Valcartier, near Quebec City (Canada), to the American Astronomical Society meeting in Austin, TX. This is the first time in a quarter of a century that such a cosmic call will be attempted.   The complete message is about 400,000 bits long and will be transmitted three times over a 3-hour period in the direction of the four selected stars. Then, it will be followed by a series of greetings from people around the world. The transmission will start on March 15 1999. Finding a transmitter for this task was not easy; the project will use a 70 m (230 ft) Ukrainian antenna equipped with a 150 kW transmitter b...

Communication with Extraterrestrial Intelligence #2 -

  "Lingua Cosmica." A language for extraterrestrial communication developed by Hans Freudenthal, Professor of Mathematics at the University of Utrecht. Details of it are presented in Freudenthal's book 1 published in the Netherlands in 1960. LINCOS represents an extension of the logistic language of mathematics developed by Alfred North Whitehead and Bertrand Russell. It is intended to be conveyed by unmodulated radio signals of varying duration and wavelength which represent phonemes. The signals would be combined to make up concepts or words. Lancelot Hogben, who himself described a code for communication with alien intelligence, called Astraglossa , discussed Freudenthal's work. The Internet Encyclopedia of Sciemce Chapter III: Behaviour 3 00 1. For the time being it would be premature to try to describe  human behaviour by a system of general rules like the mathematical  and chronometric rule...

Communication with Extraterrestrial Intelligence #2 - Lincos

Lincos : Design of a Language for Cosmic Intercourse , published in 1960 by Hans Freudenthal , expands upon Astraglossa to create a general-purpose language derived from basic mathematics and logic symbols. A new generation Lincos has been developed since 2000 by Alexander Ollongren, as a part of the more general Astrolinguistics .   Wikipedia Lincos consists of a variety of mathematical terms and phrases, to be encoded into specific combinations of radio pulses and signal shapes and then beamed out into space. It is devised purely in terms of semantics and human logic, and accomplishes understanding by building from simple beginnings. Statements are arranged in words, sentences, and paragraphs. Freudenthal’s program begins by establishing the meaning of the terms "plus" and "equals." He would, for instance, send signals something like "beep bloop beep tweet beep beep" (1 + 1 = 2), perhaps followed by "beep bloop beep beep...

Communication with Extraterrestrial Intelligence #1 - Astraglossa

An early radioglyph scheme for interstellar communication (see CETI ) proposed by the British mathematician Lancelot Hogben . He gave details of it in a 1952 lecture to the British Interplanetary Society , entitled "Astraglossa, or First Step in Celestial Syntax," and later described it in a book. 1 Hogben suggested that numbers be represented as ordinary pulses (e.g. five pulses for the number five) and mathematical concepts, such as "plus,""minus," or "equal," each by a distinctive signal – a radioglyph.
