N = the number of civilizations in our galaxy with which radio-communication might be possible
&,
R* = the average rate of star formation in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space

( Edward Tufte's explanation of The Pioneer Plaque,
from _Visual Explanations_ [ 01997 ] )
" We cast this message into the cosmos ... Of the 200 billion stars in the Milky Way galaxy, some -– perhaps many –- may have inhabited planets and space-faring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: We are trying to survive our time so we may live into yours. We hope some day, having solved the problems we face, to join a community of Galactic Civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe. "

METI Art
Similar to SETI – the Search for Extraterrestrial Intelligence (Search for ETI), where one listens for messages sent to Earth – METI means "Messaging to ETI": Sending both scientific and artistic messages to the stars. So, METI Art represents not Art about Space, but Art *for* Space. In other words, METI Art is the creative work of Earth destined for inclusion in the Planetary Consciousnesses of supposed extraterrestrial civilizations.
METI is an important quality of a global civilization marked by a mature Planetary Consciousness. The present state of Earth Consciousness is characterized in part by a low level of METI activity. The fact is that our civilization has engaged in about 100 SETI programs, and only one METI Program. Perhaps, at present, the fundamental nature of the Consciousness of Earth is characterized, in part, by a preference to *receive* rather than to *give* ? But however that may be, the scientific and technological aspects of METI are clear: Three terrestrial radar telescopes -– in Arecibo (Puerto Rico), Goldstone (California), and Evpatoria (Crimea) –- can generate signals that are detectable everywhere in the Milky Way Galaxy. In fact, humans have already transmitted four interstellar radio messages toward 16 celestial targets. But, unfortunately, the artistic aspects of METI are in a state of infancy. However, we believe the maturation of METI Art as a widespread art form will evoke an abundance of METI transmissions: With the creation of outstanding works of METI Art, our Planetary Consciousness will greatly shift toward a ‘preference to give’: toward a tendency to share our Planetary Consciousness with the cosmos.
There are at least two peculiar features of METI Art. First, it should be understandable throughout the Universe; or at least we should always strive to achieve this cardinal goal while engaging in the creative process. Second, METI Art should be laconic due to certain technical limitations on the size of interstellar radio messages.
There are at least three sorts of terrestrial Art that are understandable around the world and, presumably, would be understandable by extraterrestrials unfamiliar with Earth: music, dance, and pictures. As an example of pictures we may cite the Arecibo Message, the Cosmic Call 01999 & 02003, the Teen Age Message, and the Bilingual Image Glossary. And as an example of music we may cite the 1st Theremin Concert for Aliens. The language of dance has not yet been used in the creation of METI Art.
