I'm wondering if there's anything in the plant or animal kingdom that utilizes something like a nomogram/nomograph for estimating some function. --- On a related note, I heard a virologist say that there's a virus that is so highly developed, that it reads DNA groups of 3 _starting at EVERY location_, both BACKWARDS and FORWARDS. (Most DNA can be read in groups of 3 only at mod(3) boundaries, and can only read forwards.) If so, eat your heart out, Bach! You've been outdone by a lowly virus! Perhaps someone can convert this virus's DNA into polyphonic music? At 08:22 PM 8/30/2012, Warren Smith wrote:
