Watch: } You're missing some crucial data that cross-correlates } your 'time' series to the cerebellar topology. I couldn't possibly add anything to prove the point better. Please keep your imaginary mathematical pollution confined to your "consciousness" groups, although alt.usenet.kooks could use your input.
