Waclaw Sierpinski World War I totally disrupted the mathematical communities of eastern Europe. Rather than try to re-build comprehensive university programs in several areas of research, Sierpinski, Kuratowski, Banach and others decided to work together in the emerging field of abstract spaces. They soon became known as the "Polish School." Their first international recognition came from publishing a new journal, Fundamenta Mathematicae (1920), devoted to set theory and related topics, and not to their work in topology. Indeed, the publication of Banach's dissertation in 1922 has been called the birth of functional analysis.

Before leaving the above images, we invite the viewer to consider the following: In the upper right hand corner is the ( I, 47 ) proof of the Pythagorean Theorem from one of the world's oldest hand written copies of Euclid's Elements. To the above right are figures taken from the first printed edition. Now, on the left, we see the contribution of animation, the gift of our generation, to these famous mathematical concepts. The circle, ellipse, parabola and hyperbola are "sections" of a cone. Recall the study of cones dates to Apollnius (262-190 BC) and other early Greeks.

The Magic Sierpinski Triangle
Order dependent on randomness
This design is called Sierpinski's Triangle (or gasket), after the Polish mathematician Waclaw Sierpinski who described some of its interesting properties in 1916. Among these is its fractal or self-similar character. The large blue triangle consists of three smaller blue triangles, each of which itself consists of three smaller blue triangles, each of which ..., a process of subdivision which could, with adequate screen resolution, be seen to continue indefinitely. Fractals and self-similarity are of considerable interest in their own right, but our interest here is in how to construct Sierpinski's triangle. One way to do so is to inscribe a second triangle inside the original one, by joining the midpoints of the three sides, and then repeat the process for the resulting three outer triangles, for the three outer triangles that result from that, and so forth. But there is a more intriguing way to construct Sierpinski's triangle, sometimes called the Chaos Game
Lots of interesting questions have probably occurred to you. Does the pattern depend on the particular triangle you start with? Find out by clicking on the Custom button and creating your own triangle. Does the choice of the initial point matter? Try that out too by clicking the Clear button and selecting a new point inside the triangle. How come this construction gives the same (itself rather remarkable) pattern as inscribing triangles? We'll leave that and some other questions to

Fractals and Chaos Sierpinski Triangle Lab Report Create a Sierpinkski "Gasket" By Cutting Holes in a Triangle Purpose
The purpose of this project is to show how to create a Sierpinksi gasket, a "holey" triangle, by recursively cutting holes in a triangle. Mathematical Background Polish mathematician Waclaw Sierpinski introduced the "Sierpinski Gasket" in 1915. Starting with a triangle, recursively cut the triangle formed by the midpoints of each side: The single equilateral triangle in Step 0, is divided into four equal-area equilateral triangles in Step 2. The "middle" triangle is colored differently to indicate it has been "cut" from the object. This same "rule" is applied an infinite number of times. Here are the next two steps: Let's analyze what's happening. Consider the perimeter of the red triangles: Step Triangles 3 sides/triangle Length of Side Total Length a a/2 a/4 k k a/2 k k+1 a/2 k As k approaches infinity, the perimeter of all the red triangles approaches infinity. The area of an equilateral triangle with each side length a is . (See the von Koch Curve Lab Report for details.) For further computations here, we'll make computations as a fraction of A

Waclaw Sierpinski
, was born on March 14 in Warsaw and died on October 21 in Warsaw . He was a Polish mathematician , known for outstanding contributions to set theory (research on the axiom of choice and the continuum hypothesis number theory , theory of functions and topology . He published over 700 papers and 50 books (two of which, "Introduction to General Topology" ( ) and "General Topology" ( ) were later translated into English by the Canadian mathematician Cecilia Krieger ). Two well-known fractals are named after him (the Sierpinski triangle and the Sierpinski carpet ), as are Sierpinski numbers and the associated Sierpinski problem.
Education
Sierpinski enrolled in the Department of Mathematics and Physics at the University of Warsaw in and graduated four years later. In , while still at the University of Warsaw, the Department of Mathematics and Physics offered a prize for the best essay from a student on Voronoy 's contribution to number theory. Sierpinski was awarded a gold medal for his essay, thus laying the foundation for his first major mathematical contribution. Unwilling for his work to be published in Russian , he withheld it until , when it was published in Samuel Dickstein 's mathematical magazine 'The Works of Mathematics and Physics'.

The Sierpinski Gasket
A Sierpinski gasket is also called a Sierpinski sieve. On the left and right, we see a series of Sierpinski gaskets (drawn using Fractint and Paint Shop Pro ), discovered by Waclaw Sierpinski. The first order would just be a straight line segment. Here, I show orders 2 through 7. You should probably see how each new order is built from the previous one. The true Sierpinski gasket is the limit of infinitely many of these steps. Instead of lines, we can also build it with dark triangles (or any other object). The Sierpinski gasket is related to The Yanghui Triangle (usually called Pascal's triangle), below. I have drawn hexagons around the odd numbers. That pattern is identical to that of the Sierpinski gasket, forever. There is an interesting experiment called "the chaos game," in which random (presumably chaotic) chance produces great order. On the left, we see a picture. We draw three (or more) points (the vertices of a triangle, which doesn't have to be equilateral or isosceles), labeled 1, 2, and 3. Then we choose a starting point S, at random (the one I chose is not within the triangle). Then we begin the game. We proceed to choose random numbers, 1, 2, or 3 (with dice or whatever). Each random number defines a new point halfway between the latest point and the point toward which our random number directs us. For example, my first random number was a 1; so I drew a point halfway between S and 1. Then I got another random 1, then 3, 2, 1, and 3. After drawing 6 points, I perceive no obvious pattern. With a computer, it is easier to continue to choose many more points.

Todd Wenrich Prof. Daepp Final exam Fractal Geometry Waclaw Sierpinski was born on March 14, 1882, in Warsaw, Poland. Sierpinski attended the University of Warsaw in 1899, when all classes were taught in Russian. He graduated in 1904 and went on to teach mathematics and physics at a girl's school in Warsaw. He left teaching in 1905 to get his doctorate at the Jagiellonian University in Cracow. After receiving his doctorate in 1908, Sierpinski went on to teach at the University of Lvov. During his years at Lvov, he wrote three books and many research papers. These books were The Theory of Irrational numbers Outline of Set Theory (1912), and The Theory of Numbers (1912). In 1919, Sierpinski accepted a job as a professor at the University of Warsaw, and this is where Waclaw Sierpinski (The Mactutor) he would spend the rest of his life. Throughout his career, Sierpinski wrote 724 papers and an amazing 50 books. Sierpinski studied many areas of mathematics, including, irrational numbers, set theory, fractal geometry, and theory of numbers. Sierpinski is viewed as one of the greatest Polish mathematicians ever. He is noted for his construction of the Sierpinski gasket. (The Mactutor) Sierpinki gasket (The MacTutor) Sierpinski Carpet (Bunde) The Sierpinski carpet for the above example has n = 5 and k = 9. It is possible for the carpets to look different when k is changed. Using the same idea as for the calculation of the dimension of the gasket, we denote by L the length of a square side and by the M mass of the carpet. Considering that n^2 – k smaller squares with side length L/n make up the whole carpet with side length L we get M(L) = (n^2 – k) M (L/n). Combining this with the general formula M = A L^d for some constant A we get (n^2 – k) A (L/n)^d = A L^d which simplifies to n^2 – k = n^d. Taking logarithms on both sides and solving for the dimension we get d = log(n^2 –k) / log n. In the example above, the fractal dimension is log(16) / log(5) = 1.7227….(Daepp)

last updated: The Sierpinski curve is a base motif fractal where the base is a square. After subdivision in 3x3 equal squares the motif is to remove the middle square: The curve is also known as the Sierpinski (universal plane) curve, Sierpinski square or the Sierpinski carpet
It has named after the Polish mathematician Waclaw Sierpinski (1882-1969), but it was Stefan Mazurkiewicz who found the curve (in 1913). The curve is the only plane locally connected one-dimensional continuum S such that the boundary of each complementary domain of S is a simple closed curve and no two of these complementary domain boundaries intersect.
Wow!
In other words: the Sierpinski curve contains a topologically equivalent copy of any compact one-dimensional object in the plane. The fractal dimension of the curve is equal to log 8/ log 3, i.e. about 1.8928
The curve is a two-dimensional generalization of the Cantor set
Some kind of shells (conus textilus, conus gloriatnatis) have patterns that resemble the Sierpinksi square.

waclaw sierpinski was not the first one to come up with this idea, for thesefigures have been found on patterns drawn on the pulpit of a 12th century
http://cushman.net/projects/fractals/
Fractals and Chaos in Nature In the past two decades, scientists and mathematicians have developed a new way of looking at the universe around us, a new science that better describes the irregular shaped objects we find in nature and math. As James Gleick put it, "This new science, called chaos, offers a way of seeing order and pattern where formerly only the random, erratic, the unpredictable - in short, the chaotic - had been observed". Scientists had come upon an important tool in understanding nature. This science, along with the closely related science of fractals, models real-world situations better than anything else before. In 1961 at MIT, Edward Lorenz developed a model for an ideal weather system with few variables. He came up with three equations to reflect the changes on a computerized graph. These equations are defined to be: dx/dt = 10(y-x)
dy/dt = xz+28x-y
dz/dt = xy-(8/3)z
He was studying changes in the weather, but he unknowingly founded the science of chaos. He discovered that small changes in the initial conditions would produce large differences in the long run (Stevens 63) The computer that Lorenz ran his system of equations on would compute the digits out to an accuracy of six decimal places. When Lorenz wanted to re-simulate a section on the graph that was produced, he started the computer over again at the beginning of the section in question, only with three digits of accuracy, instead of six. After a short period of time, Lorenz could see a large difference in the two graphs. This led to the discovery of the Lorenz attractor, a butterfly-shaped graph. When these equations are graphed on a computer, the output is chaotic, but orderly. These equations model such natural phenomena as the flow of fluid, or the movement of a water wheel

The Sierpinski Problem: Definition and Status
In 1960 Waclaw Sierpinski (1882-1969) proved the following interesting result. Theorem [S] There exist infinitely many odd integers k such that k n + 1 is composite for every n A multiplier k with this property is called a Sierpinski number . The Sierpinski problem consists in determining the smallest Sierpinski number. In 1962, John Selfridge discovered the Sierpinski number k = 78557, which is now believed to be in fact the smallest such number. Conjecture. The integer k is the smallest Sierpinski number. To prove the conjecture, it would be sufficient to exhibit a prime k n + 1 for each k Summary of results. This summary describes developments in the computational approach to a possible "solution" of the Sierpinski problem, from the earliest attempts in the late 1970ies until November 2002, and gives a comprehensive status of results known at that point.
