How To Talk To Aliens
Frederic Friedel writes: "In their efforts to talk to alien civilizations human beings are currently
engaged in sending pictures based on a rectangular array of dots, arranged
from left to right and top to bottom. But is this stategy sound? For
instance
what if the aliens do not see in pictures at all, or if they think in vector
graphics rather than bitmap? On ChessBase.com
grandmaster John Nunn proposes sending them a
trading machine instead."
They stole this idea from Contact. The first layer of the signal was a list of the first so many prime numbers.
Your post reminded me of this funny little short story.
