Presseurop: The secret of 3% finally revealed (28 September 2012)
Guy Abeille, age 62, a former senior Budget Ministry official and "the inventor of the concept, endlessly repeated by all governments whether of the right or the left, that the public deficit should not exceed 3% of the national wealth," told the newspaper -
We came up with the 3% figure in less than an hour. It was a back of an envelope calculation, without any theoretical reflection. Mitterrand needed an easy rule that he could deploy in his discussions with ministers who kept coming into his office to demand money. [...] We needed something simple. 3%? It was a good number that had stood the test of time, somewhat reminiscent of the Trinity.
The daily remarks on the strange character of this anecdote: "In an irony of history, the technocrats in Brussels drew on the legendary 3% for inspiration when creating another rule [stipulated by the new Fiscal Compact], just as factitiously Cartesian, which obliges states to limit their structural deficits to 0.5%. Why not 1% or 2% ? No one really knows."

Just wow.
There is material here for several books on political theory, sociology, anthropology ...

The wikipedia article on Abeille links to this from 2010:
Pourquoi le déficit à 3% du PIB est une invention 100%... française

J'en viens au seuil magique - pour un peu, chamanique - du déficit à 3% du PIB.

Speaking of the Trinity...

Look at that effort of thirty billion euros of debt reduction in the French budget (nice round number!)

  • 10 billion in spending cuts (the father?)
  • 10 billion from business (the son?)
  • 10 billion from households (holy moley!)

It's sometimes cheaper to pay them directly than to have them form think tanks.

(Not always, so remember to ask me about each case individually.)

An American strategic analyst I met briefly at a conference way back in Copenhagen insisted that 3.18 was a magic number of stability in 'economics': he had some algorithm based on sustainable growth, paying down debt through inflation and the fact that 3.18% growth would represent a doubling in 22 years i.e. a generation.  He never once mentioned chaos theory, but (and here I am open to brickbats) in complex dynamic systems there does appear to be algorithmic significance.

I'm not impressed by generational theories since the birth rate in most societies is fairly stable during a couple of decades. 'Generation' as in 'Talking about my...'. Generations continuously overlap, but the major phenomena that influence the culture of a society (pan-generationally): Depression, WWII, the Beatles, Thatcher, or whatever, do have an impact/aftermath that is maintained within a certain period (22 years?), after which the phenomena tend to become museified.

22 years i.e. a generation

Yeah, and 22 = 2*11.

Which goes to prove all even numbers can be derived as the sum of two primes.

Algorithm:  A process or set of rules to be followed in calculations or other problem-solving operations

The canonical definition of the Mandlebrot Set:

Is an algorithm.  

So is the Feigenbaum Function.  But whether one "gets" this:

this:

or this:

depends on one's interpretive stance.

Not as such:

ABSTRACT. We provide a definition of an attractor to a multivalued iterated function system (IFS) modelled on previous ones existing in the literature (e.g. [Hale, J. K.: Asymptotic Behavior of Dissipative Systems. Math. Surveys Monographs 25, Amer. Math. Soc, Providence, RI, 1988]). Such an attractor expressing asymptotic behaviour of a system does not need to be invariant. Then, as a remedy there serves the uniform Hausdorff upper semicontinuity It was recently shown that condensing multifunctions possess a maximal invariant set which is
compact. The theorem ensuring the existence of attractors considered here also exploits compactness-like hypothesis slightly stronger than condensity, namely contractivity with respect to measure of noncompactness. Hence contractivity in measure and uniform Hausdorff upper semicontinuity together do guarantee existence of a compact attractor which is maximal invariant and unique. We also supply examples (e.g. unbounded attractor) and state further questions.

Nutter?  Not as such.  I very seldom go gathering nuts.

I prefer to think of myself as one who works on the leading edge, expanding the boundaries of what is possible with human/cybernetic Information Systems:
