Comment Re:Moon's face towards the earth? (Score 1) 64

I understand that the moon is tidally locked with the earth. What I don't understand is why the moon's movement is described as being "such that the same face is always facing the Earth." It appears to me as though the same area of the moon is being constantly lit by the sun. Doesn't that mean that that "face" is always facing the sun? I am not trying to be argumentative nor refute Cassini's Laws. I am just trying to understand the meaning of "face" in this particular context.

Music By Natural Selection 164

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."
