Hi,
Thanks for the welcomes. "Does God Play dice" is an excellent book - I think I'm Chapter 10 or 11 in another of Ian's books "Life's Other Secret" which describes he crowds/fractal connection.
The conference where I met, and talked through into the early hours, with Benoit Mandelbrot was all related to crowds, fractal analysis in the financial markets and the nature of information and connectivity. The Xenofractals and the notes I took during that meeting were all focussed on the "why" do the markets behave in this way - sure they are fractal - but why are they fractal.
Mostly this is due to the nature of how a group interacts ("It's all in the interactions") - you can build cellular automata models to explore the connectivity and I did a lot of work on "TradeStation" on chaos detectors ("don't trade chaos") where the crowd reactions were non coherant. When the crowd is coherent there is a degree of predictability - so a 0-1 chaos detector allowed me to discriminate between chaotic and non-chaotic signals....improved the trading performance (and I made a bit of money too).
However - crowd safety has always been my passion.
There is an article Ian wrote (for Discover Magazine) which explains the start of the journey (
http://www.xenofractals.com/Cobweb.html) in his words.
Since then I've gone on to model (and design) some of the worlds largest, most dangerous and complex crowded spaces.
Right now - I'm getting back into programming the Xenofractals and if anyone out there is interested in some serious discussions - I'd love to hear from you. They were cover disc on PC World and Focus Magazine (over 1,000,000 distributed) which also featured a free book from Arthur C. Clarke - hence his letter to me and the subsequent discussion on the fracas systems.
Sadly, both Arthur and Benoit are no longer with us - so these are treasured memories and letters.
Kind regards,
Keith
