Floco de Neve e Curva de von Koch A curva de Koch foi apresentada pelo matemático sueco Helge von Koch, em 1904, construindo-a a partir de um segmento de recta. Construção da Curva de von Koch: Divide-se esse segmento em três partes iguais. Substitui-se o segmento médio por dois segmentos iguais, de modo a que, o segmento e médio e os dois novos segmentos formem um triângulo equilátero. Obteve-se uma linha poligonal com quatro segmentos de comprimento igual. Posteriormente, repetem-se os passos para cada um dos segmentos obtidos. Obtém-se assim, no limite de iterações, uma curva que pode ser considerada como um modelo simplificado de uma costa, no entanto, quando comparada com a última, esta curva tem uma irregularidade demasiado sistemática. Tal como uma costa, a curva de von Koch tem um comprimento infinito. Esta curva deu origem a um outro fractal, conhecido como floco de neve ou ilha de von Koch (modelo rudimentar da costa de uma ilha e muito semelhante a um floco de neve). Este último modelo é construído partindo de um triângulo equilátero.

64. EROSION CONTROL | FEATURE ARTICLE - The Fractal Nature Of Erosion Discovered by mathematician helge von koch in 1904, this snowflake is a primeexample of the fractal geometry related to the problem of measuring Great http://www.forester.net/ecm_0205_fractal.html

An abstract mathematical concept might eventually help create erosion-prediction models. By John M. Fuhrmann fractal predict erosion as well. It is time for this groundbreaking research to graduate from the laboratory to the field. The recent findings open a warehouse of mathematical tools to the erosion community. Fractal mathematics fills volumes of dusty books, and the critical discovery by Yonathan Shapir, Ph.D., and his colleagues pierces the membrane between physical erosion and years of complicated mathematical theory. The future of erosion research promises to be an exciting one as the Rochester laboratories pass the baton to geologists, engineers, and landscape architects. Fractals, Fractals Everywhere

65. Lindenmayer Fractals - Generating Fractals - Examples It is named after helge von koch, who described it in 1904. Also known as thekoch curve. It can also be called the koch island, but this can be confused http://www.math.ubc.ca/~cass/courses/m308-03b/projects-03b/skinner/ex-generating

Generating Fractals - Examples In the examples below, clicking on the image will open a PostScript slide show of the consecutive iterations of that particular fractal. The PostScript files are huge, so they have been placed in ZIP files. When you click on an image, choose to save the ZIP file to disk. Once it has completed, choose to open the file, and then double-click the PostScript file contained in the ZIP file to run the slide show Note that if the first iteration is blank, it is not part of the slide show The first iteration is blank if the initial axiom contains no movement characters; that is, if the turtle doesn't move during translation of the axiom into an image. Koch Snowflake Initial Axiom F++F++F Transformation Rules Initial Heading (degrees) Rotation Unit (degrees) One of the best-known Lindenmayer fractals, the Koch snowflake is produced using quite a simple Lindenmayer grammar, as fractals go. It is named after Helge von Koch, who described it in 1904. Also known as the Koch curve . It can also be called the Koch island , but this can be confused with the quadratic Koch island below.

Iterated Function Systems Larry Riddle Home Sierpinski Gasket Sierpinski Carpet Sierpinski Pentagon ... Paul Levy Construction Animation Start with an isoceles right triangle . Replace this triangle with two isoceles right triangles so that the hypotenuse of each new triangle lies on one of the equal sides of the old triangle. Place each new triangle so that it points out from the original triangle to get . For the next step, repeat the process on each of the triangles that make up , as illustrated in the figure below. For each new iteration, replace each triangle in Lk by two isoceles right triangles. The Levy dragon is the limiting set of this iterative construction. Notice that at each iteration, the sides of each triangle in Lk are scaled by a factor 1/sqrt(2) [see IFS discussion below], so that the area is scaled by 1/2. But each triangle in Lk Suppose that the original isoceles right triangle is placed so that its hypotenuse is the unit interval on the x-axis and the opposite corner is at (1/2, 1/2). Then each leg is equal to . This means that we must scale the triangle by the factor r = to get each of the new triangles for x and y directions. This yields the following IFS

Teachers Perfect and Pathological Mathematics I. Course description Quick! When is a coffee cup equivalent to a donut? Is it possible for a shape to have infinite surface area and finite area? How do you know? In this class, we will meet the fringe elements of the world of mathematics: we'll encounter well-behaved and mathematically beautiful ideas and theorems, and we'll spend a lot of time with the misbehaving miscreants that have stymied long-held mathematical assumptions. We'll not only study the functions, curves and ideas that have reassured and rocked the world of math; we'll also study the means by which a theorem, proposition or lemma becomes mathematically valid. In addition, we'll explore the lives of the movers and shakers of the history of math and develop some ideas about the evolving nature of mathematics. Was it invented or discovered?

Filosofia Politica IPSE DIXIT Helge von Koch Nacque a Stoccolma il 25 gennaio 1870; figlio di Richert Vogt von Koch, militare di carriera, e di Agathe Henriette Wrede, Helge Von Koch frequentò una buona scuola superiore di Stoccolma, completando i suoi studi nel 1887, quindi si inscrisse all'Università di Stoccolma. Pubblicò numerosi lavori di matematica, riguardanti i sistemi lineari e le equazioni differenziali, per i quali fu molto apprezzato, e, infine, nel 1911, divenne professore di matematica all'Università di Stoccolma. Von Koch è famoso per la curva che porta il suo nome e che apparve nel suo lavoro Une méthode géométrique élémentaire pour l'étude de certaines questions de la théorie des courbes planes , pubblicato nel 1906. Morì sempre a Danderyd, presso Stoccolma l'11 Marzo 1924.

The von Koch Curve A line is divided into three equal parts, on the middle third an equilateral triangle is drawn whose base is removed. If you as starting line choose the sides of an equilateral triangle, in the limit you get the von Koch snowflake curve. This curve was constructed by the swedish mathematician Helge von Koch (1870 - 1924) as an example of a continuous curve in the plane without a tangent at every point. The same curve is also an example of a nowhere differentiable continuous function.

Related Web Sites Classification of Curves There are many ways to classify curves. One way is to determine whether a curve is the graph of some polynomial equation p[x,y]==0. The graph of a polynomial equation are called algebraic curves.. Algebraic curve are assigned an order . The order of an algebraic curve is the degree of the polynomial. For example, line (a x + b y + c == 0); circle ((x+h)^2 + (y+k)^2 -r^2 == 0), or the deltoid ((x^2+y^2)^2 - 8 a x (x^2 - 3 y^2) + 18 a^2 (x^2 + y^2) - 27 a^4 == 0), are algebraic curves. Curves may be easy to trace but are not algebraic. For example, no polynomial's graph can be any of cycloid equiangular spiral , or quadratrix of Hippias . Algebraic curves with degree greater than 2 are called higher plane curves. Non-algebraic curves are called transcendental curves. To determine whether a curve is algebraic requires graduate level math knowledge, and is beyond this project's scope. Here we will group curves by tracing methods.

75. Chaos Theory: A Brief Introduction One mathematician, helge von koch, captured this idea in a mathematical constructioncalled the koch curve. To create a koch curve, imagine an equilateral http://www.imho.com/grae/chaos/chaos.html

Chaos Theory: A Brief Introduction What exactly is chaos? The name "chaos theory" comes from the fact that the systems that the theory describes are apparently disordered, but chaos theory is really about finding the underlying order in apparently random data. When was chaos first discovered? The first true experimenter in chaos was a meteorologist, named Edward Lorenz. In 1960, he was working on the problem of weather prediction. He had a computer set up, with a set of twelve equations to model the weather. It didn't predict the weather itself. However this computer program did theoretically predict what the weather might be. One day in 1961, he wanted to see a particular sequence again. To save time, he started in the middle of the sequence, instead of the beginning. He entered the number off his printout and left to let it run. When he came back an hour later, the sequence had evolved differently. Instead of the same pattern as before, it diverged from the pattern, ending up wildly different from the original. (See figure 1.) Eventually he figured out what happened. The computer stored the numbers to six decimal places in its memory. To save paper, he only had it print out three decimal places. In the original sequence, the number was .506127, and he had only typed the first three digits, .506. By all conventional ideas of the time, it should have worked. He should have gotten a sequence very close to the original sequence. A scientist considers himself lucky if he can get measurements with accuracy to three decimal places. Surely the fourth and fifth, impossible to measure using reasonable methods, can't have a huge effect on the outcome of the experiment. Lorenz proved this idea wrong.

Su aritmética transfinita encontró mucho rechazo: Henri Poincaré dijo que la teoría era "una enfermedad" de la que algún día llegarían las matemáticas a curarse; Hermann Weyl se refirió a la jerarquía de alephs establecida por Cantor como "niebla en la niebla"; Leopold Kronecker , uno de los maestros de Cantor, le calificó de "charlatán científico", "renegado" y "corruptor de la juventud". El propio Cantor se resistió al principio a aceptar la existencia de tales números. La idea de infinito completo se venía rechazando desde , a causa de las paradojas que planteaba.
