Mitchell Feigenbaum 's father is Abraham Joseph Feigenbaum, an analytic chemist whose parents had emigrated from a town near Warsaw in Poland to the United States. Mitchell's (or Mitch's as he is known) mother is Mildred Sugar whose parents emigrated to the United States from Kiev. Mitchell was the middle child of his parents three children, having an older brother Edward and a younger sister Glenda. Mitchell entered a public school for gifted children when he was five years old. Unlike Edward who displayed all the characteristics of a child prodigy, reading from a very young age, Mitchell could not read when he entered school and he needed tutoring from his mother to bring him up to the level of the other children. Moved to a different school, he became somewhat bored and had no friends among the other children. In fact up until the time he went to university Mitchell would not enjoy the company of his fellow pupils. Feigenbaum's mother taught him algebra when he was in the fifth form but reading continued to be something that he did not like much. Perhaps the reason was that he tried reading articles in

V príspevku je poukázané, že vo viacerých oboroch èinnosti sú prejavy deterministického chaosu spojené s vlastnosami spätnej väzby v danej oblasti. V technických systémoch je známa syntéza obvodov s vlastnosami deterministického chaosu a bolo poukázané na jeho kladné vlastnosti.

Mitchell Feigenbaum

Toyota Professor Nonlinear systems and "chaotic" dynamics. Our lab investigates the new field of nonlinear systems and "chaotic" dynamics. We create analytical methods of description and time evolution of complicated disordered phenomena. It is the main effort of this laboratory to extend the scope of the problems over which these methods hold sway, to extend the methods themselves developing appropriate mathematics and to improve the methods for extracting such information from actual experimental studies ranging from fluids to brains.

Mitchell Feigenbaum

Toyota Professor Attempts at the analytical description of nature regularly encounter strong nonlinearities. The majority of existing methods treat only weak nonlinearities and consist of corrections to behaviors that are simple distortions of linear behavior. The methods in the strong case, on the other hand, are largely recent developments and pertain to behaviors qualitatively distinct from linear ones. One of the most striking such behaviors is the appearance of highly erratic spatial configurations and/or highly erratic temporal evolution, a phenomenon called "chaos." The hallmark of chaotic motion is a lack of predictability despite the total absence of any random ingredients. Even if one should want to determine just statistical properties of these motions, the methods of statistics cannot be applied in any straightforward manner. This impediment is a consequence of the fact that the motion, rather than exploring all possibilities allowed to it by the constraints of finite energy, finite resources, etc., instead lies in a highly complicated subspace a so-called strange set or strange attractor. Thus an a priori calculated average over "everything" will generally produce erroneous results.

Bifurcation Diagrams - Feigenbaum, Mitchell
Iterating a formula, it is possible that the results walk to a fixed value. Raising a parameter the behavior changes to two periodically repeating values. With a more raised parameter you can see another bifurcation into four different values, that change to the next at every new iteration. A little bit later, there is one more bifurcation, etc. Beginning with a critical parameter-value no more order can be seen; the output values are chaotical and the next iteration result depends on minimal variations behind the decimal point in the input.
My program Feigenbaum 4.1 (for Win) explores formulas in the described way and also allows time-diagrams, graphical iteration, phase diagramms in 2 or 3 dimensions and even Liapunov-Pictures. You can order the program only by EMail (please send me an aquivalent: ideas, pictures, programs, education-concepts, etc. with your mail). You are allowed to use the programs for your own, but not to distribute it to others!

The short answer:
However, noone should be satisfied by that. In fact, this number is perhaps the most fantastic aspect of this fractal. There are many many formulas that produce the same tree, but the number is always the same. It is said that mr. Mitchell Feigenbaum called home to his mother when he discovered this universality and said this was going to make him famous. The famous value, comes when you compare the length of one part of the tree, that is a parts between the line divisions/bifurcations. See illustration at right. The first part is from -0.25 to 0.75, and has a length of 1.00. The next part is from 0.75 to 1.25, and has a length of 0.50. The relationship between the two lengths is 1.00/0.50=2.00. Now that is far from the Feigenbaumvalue, but the exact value springs up when you compare two parts as far right as possible, as long as x follows a periodic orbit. I have graphically found the values for the first 6 bifurcations: Bifurc no. Divides at Length This length/next length -0.25 - - 1 0.75 L1=1.0 L1/L2=2.0 2 1.25 L2=0.5 L2/L3=4.25 3 1.3677 L3=0.1147 L3/L4=4.492 4 1.3939 L4=0.0262 L4/L5=4.6208 5 1.39957 L5=0.00567 L5/L6=4.536 6 1.40082 L6=0.00125 L6/L7=?

Feigenbaum, Mitchell (1945- )
Mathematician, born in Philadelphia, PA. He is one of a small group of scientists who in the 1970s were growing more concerned about the inability of science to explain irregular occurrences in everyday life, such as the shape of clouds, the irregular flow from a dripping tap, and many other events that could be described as chaotic. He developed the mathematics of what is now called Chaos Theory, used in fields such as meteorology, aerodynamics, and ecology. You can check out his home page at Rockefeller University.

    In 1975, the eccentric scientist Mitchell Feigenbaum was probing the possibility that there was a point at which periodic equations turned chaotic. With his calculator he began to use a combination of analytic algebra and numerical exploration to piece together an understanding of the quadratic map, concentrating on the boundary region between order and chaos. He noticed that it took increasingly more time to work out his answers, and as he waited for his output of data, it dawned on him that the numbers were converging geometrically. This suggested that an unexpected regularity was embedded in the system and that some part of it was repeating itself on different scales. Feigenbaum calculated this ' ratio of convergence ' as 4.669 to 3 decimal places. Unsure what the significance of this value really was, Feigenbaum started to analyse other functions that went through a sequence of bifurcations on the way to disorder. He found that each one produced the same ratio of convergence. In terms of chaos, this value is equal to the scale at which the bifurcation diagram is self-similar - i.e. make the diagram 4.669 times smaller and it will look like the next region of bifurcations. This universality was a revolutionary discovery as it gave scientists the first tools to analyse a chaotic system. BACK TO CHAOS THEORY
