Extractions: and Numbers' Structural Legacy "It is a pleasure to be here. As I was walking outside and smoking, I noticed that there is a motto on the building. The motto says "Get knowledge, get riches but with all thy gettings get understanding". Basically that is what I will try to talk about. The subject of physics concerns itself with things that are characterized by order, regularity and invariance. These are almost the same words, and I will try to address as I go along different aspects of that. do with nature. You probably know that Pythagoreans took that relation very seriously and regarded nature as coequal to number. Moreover, nature was regarded as a discretion, in the sense that it was discrete, built out of pieces, so to speak numbers. It is hard to know what these things mean, one has lost too many references over the millennia. You probably know that in general we don't believe that anymore, that is, we don't believe in general that the world is discrete. That doesn't mean we can't entertain the possibility that it is. The notion (of convention) of a continuum makes sense when one thinks of Zeno's paradoxes, which are paradoxes against the idea of the world being discrete, but rather needing a continuum for its description.
Exploring The Feigenbaum Fractal What is the logistic equation? The logistic equation is the formula MitchellFeigenbaum mainly worked upon developing the theory behind these fractals. http://www.stud.ntnu.no/~berland/math/feigenbaumold/explore.html
Extractions: This page is not finished yet, but will contain the following topics. The logistic equation is the formula Mitchell Feigenbaum mainly worked upon developing the theory behind these fractals. The formula is meant to describe population. A simple model of population over time is a proportional relationship to the last year. Say we had x animals last year. This year we should have a*x animals. But this does not apply to the real nature. A better description would be to include a factor dependant on how much room there is left, and let x express the ratio of fullness in the area (from to 1). Then the 1-x factor is added, so that if the area is almost full, the population will not increase beneath the upper limit. Expanding the logistic equation, we get:

Extractions: glucocorticoids as part of their immunosuppression regimen. All pharmacological interventions have failed to prevent osteoporosis in patients receiving long-term glucocorticoids. However, we have clearly demonstrated that resistance exercise is osteogenic and effective in preventing glucocorticoid-induced osteoporosis. We are currently examining the efficacy of combining the anti-resorptive effects of bisphosphonate agents with the osteogenic effects of progressive resistance training in an attempt to devise the optimal anti-osteoporosis therapy for organ transplant recipients. We are concurrently investigating the catabolic effects of glucocorticoids on skeletal muscle in organ transplant recipients. Through muscle biopsy techniques and gel electrophoresis we are determining the efficacy of resistance exercise training in reversing skeletal muscle myopathy in both heart failure and heart transplant recipients.

CHAPITRE 4 : LA CONSTANTE DE FEIGENBAUM Translate this page La découverte de cette constante est due entièrement au mathématicien MitchellJ. feigenbaum, qui l'a calculée à l'aide d'une simple calculette vers 1975. http://josephv.test.free.fr/fractal/feigenbaum/FEIGENBAUM.html

Pour tenter de visualiser les variations de cet attracteur en fonction du paramètre , on peut utiliser la procédure feigenbaum , qui admet trois arguments : début et fin sont les bornes respectivement inférieure et supérieure de l'intervalle des paramètres que l'on veut visualiser. pas est la distance que l'on prend entre deux points consécutifs de l'intervalle considéré. Plus l'intervalle est étroit, plus on a intérêt à choisir pas petit, mais il faut naturellement tenir compte de la vitesse et surtout de la mémoire de la machine. On pourra aussi modifier le test d'arrêt de compteurs de boucle k au sein de la procédure. Dans un premier temps, feigenbaum(1,4,pas) , où pas est à définir (par exemple 0.01), permet de visualiser les variations générales. On obtient ce qu'on appelle le diagramme de Feigenbaum Comme on l'a vu dans le chapitre 1 , l'attracteur est d'abord formé d'un unique point, qui est le point fixe attractif de l'itérateur. Puis apparaissent successivement les cycles de longueur 2, 4, 8, ..., pour des valeurs successives des paramètres qu'une utilisation patiente et minutieuse de la procédure

Advent...or Waiting I was reading recently about the work of the mathematician MitchellFeigenbaum. He wanted to understand how it could be that patterns http://unitytemple.org/sermons/Archive/wait98.htm
Extractions: December 6, 1998 couple of weeks ago I spoke of Harvest, the time when things are ripe and it is time to harvest it. Many of the moments of our lives are times for some small harvest and a few moments are ripe for some major gathering in of the fruit of long periods of planting and laboring and waiting. But most of the moments of our lives are planting times, watering times, waiting times, nothing quite ripe. I will not ask, have you ever waited. Everyone has waited, and wondered, felt sometimes the stagnancy and sometimes the dread of waiting. If your religious background is Christian, you will recognize this season as Advent, and Advent is about that, really. It comes from biblical stories composed by Jewish people living under a cruel Roman occupation. They placed their hope in a Messiah. The Galilean teacher Jesus began to teach a different vision of what this Kingdom was that they were supposed to be waiting for. It is hard to wait, and there is something in us that feels itself to be waiting because it is stirred by hope as well as fear, something in us that wants to know how to wait, how to be with this time. But we wait. In a hopeful discontent in our private lives, and beyond that, we may feel the advent of some great spiritual renaissance that is slowly emerging from the ruins of our civilization.
