Dr. John Hamal Hubbard Dynamical Systems Laboratory THE LAST LAUGH Copyright (C) 1990 by Homer Wilson Smith A Mandelbrot fractal is a statement of how well something survives in a given environment. If it does NOT survive well you give the environment some color of the rainbow specifying how quickly the thing died. If the item in question DOES survive well or lives forever you color that environment black. Mathematically speaking infinity does not mean infinite survival. Infinity means infinite change, which means death. Thus in the Mandelbrot plane if the iterated variable Z goes off to infinity that means it died and you give the environment (C) some color representing that fact. What the variable does in the black area of the Mandelbrot set is not much better as far as survival is concerned. In the black area the iterated variable attains a steady state of no change at all, or a periodic change from one state to another and back again. This too is not life. Life is not a rock or a statue. It is a constantly changing system. You grow, you change, you shed your entire skin every so often, you replace broken parts, you age, you split in half, or you procreate and then die. This is very unlike the behavior of the variable going off to infinity and it is very unlike the variable hanging out at a fixed point or fixed period cycle. Life much more resembles the iterated variable involved in a chaotic attractor, those areas of constant change within reasonable boundaries. One last point should be made here. Once the iterated variable reaches a fixed point or cycle, it stays there BECAUSE the environment is not changing. But in real life the environment is always changing and in fact is often changed by the very production output of the iterated item in question. Thus what may be a fixed point during one iteration may no longer be a fixed point during the next iteration because the environment variable (C) has changed. Thus the iterated variable, the inside trying to survive in an outside, may constantly skit around looking for stability to find that it always eludes its grasp. A lot of people laugh at 'The Cell and the Womb' or the idea that fractals have anything to do with insides surviving in outsides. However the fact remains that what happens to Z is a function of what Z was just a moment before and EVERYTHING ELSE IN THE WORLD THAT IS NOT Z. If that is not something 'surviving by changing' in an environment not itself, then I don't know what is. You got to remember something about fractals. A long time ago Ben Franklin was playing around with electricity and he came up with some interesting theories to explain some very iteresting phenomenon. They really knew how to zap people in those days, what with Leyden jars and kites on strings and all. Everyone had to 'feel the spark', that was part of their initiation into the inner conclave of Electricians. If you didn't pass the initiation, either by accident or otherwise, they buried you and found someone else. No joking, Leyden jars ganged in parallel could store millions of volts and throw sparks 2 feet long. But they still thought electricity was a liquid that you could dissolve in water. That's HOW they discovered the Leyden jar. ZAP! This was all very impressive to everyone involved, but does this mean that Ben was right? No of course not, Ben's ideas of electricty were near ridiculous. It took a guy by the name of Faraday to make any real sense out of the matter, but to hear HIM talk of it Ben was a pioneering genius. That's because before Ben's time people were pretty much passing banana's back and forth in the trees as far as electricity was concerned. Ben made the first bold steps towards making electricty a respected and controllable subject of knowledge. Just so today with fractals. Chaotic dynamical systems is a VERY VERY NEW field of math and it is VERY DIFFERENT from anything that has gone before. People have no idea what is there to be found and people have no idea what it could be used for. They might as well be passing bananas back and forth in the trees when it comes to fractals. So you could say that these ideas about the 'Cell and the Womb' and so forth are in the Ben Franklin stage of discovery. No one has even proven them wrong yet. They are still LAUGHING at them, don't you see? The Faraday stage of development where they get ripped apart and put back together again correctly is still way down the road. But in 200 years people will know what I was talking about and not only will they be able to prove that their technology is correct they will be able to use it to incredible ends. Of course we may not be able to recognize these original ideas in the final useable version, just as Ben's original ideas have been lost in the upgrades. But the people who LAUGHED at Ben were not the ones to make the upgrades, and Ben himself would have been the first to embrace the improvements even if it had meant leaving his own name in the dust. And with that attitude you can be sure his name never will be left in the dust.
