14.13i is 0.87i from 15i.............511, rearranged, e to the 2pi .............2.7^6.28, 67, 71 six and seven........a -   g, 7 musical notes.....music of the p's indeed.........r = 1/2 c = pi......exactly......as black idiots say, who think they are educated........EXACTLY..

History

Feigenbaum originally related the first constant to the period-doubling bifurcations in the logistic map, but also showed it to hold for all one-dimensional maps with a single quadratic maximum. As a consequence of this generality, every chaotic system that corresponds to this description will bifurcate at the same rate. Feigenbaum made this discovery in 1975,^[2][3] and he officially published it in 1978
