## A Galilean Dialogue

GEB is recommended reading if you want a book which you can finish in maybe a lifetime or two. Here is a passage: To show why order versus chaos is such a subtle and significant issue, and to tie it in with questions of location and reveleation of meaning, I would like to quote a beautiful and memorable passage from "Are Quanta Real" - A Galilean Dialogue, by the late J.M.Jauch: SALVIATI: Suppose I give you two sequences of numbers, such as: 7, 8, 5, 3, 9, 8, 1, 6, 3, 3, 9, 7, 4, 4, 8, 3, 0, 9, 6, 1, 5, 6, 6, 0, 8, 4 .... and: 1, -1/3, +1/5, -1/7, +1/9, -1/11, +1/13, -1/15 ... If I asked you, Simplicio, what the next number of the first sequence is, what would you say? SIMPLICIO: I could not tell you. I think it is a random sequence and that there is no law in it. SAVLVIATI: And, for the second sequence? SIMPLICIO: That would be easy. It must be +1/17 SALVIATI: Right. But what would you say if I told you that the first sequence is also constructed by a law and this law is in fact identical with the one you have discovered for the second sequence? Now, that is interesting ... can you find out this law?

The first series is the digits of the expression (PI / 4) which is (3.14159... / 4) ~ 0.78539816339744830961566084.... Sum to N (N is very much greater, approaching infinity) numbers of the second series leads to the same value given above.

Right!
