	Wacław Sierpiński - Wikipedia, the free encyclopedia
		Sierpinski began to study set theory and, in 1909, he gave the first ever lecture course devoted entirely to the subject.
		Sierpinski was awarded the scientific prize of the first degree in 1949.
		Waclaw Sierpinski is interred in the Powązki Cemetery, Warsaw, Poland.

	Fractals: Sierpinski Curve
		The Sierpinski curve, named from the polish mathematician Waclaw Sierpinski who originally devised it around 1912, is much less known than the other fractal objects created by Sierpinski and his co-workers as the Sierpinski gasket or the Sierpinski Carpet.
		The Sierpinski curve also share the very interesting property of the most fractals: its area converges rapidly to a finite limit while the total length of the segments that composed that curve have no limit.
		This was a period of Russian occupation of Poland and despite the difficulties, Sierpinski entered the Department of Mathematics and Physics of the University of Warsaw in 1899.

	Space-Filling Curves (Site not responding. Last check: 2007-10-22)
		For example, the name Hilbert space-filling curve should properly be used only for the limit curve reached as the level parameter of the Hilbert curves tends to infinity.
		The Sierpinski group of curves use isosceles right-angled triangles as cells.
		The Sierpinski_C curve and the Sierpinski curve are, in a sense, complements of each other: the shape of the areas excluded by one curve is the shape included by the other.

	Waclaw Sierpinski (Site not responding. Last check: 2007-10-22)
		Sierpinski graduated in 1904 and worked for a while as a school teacher of mathematics and physics in a girls school in Warsaw.
		The length of the curve is infinity, while the area enclosed by it is 5/12 that of the square.
		Sierpinski continued working in the "Underground Warsaw University" while his official job was a clerk in the council offices in Warsaw.

	Sierpinski curve (Site not responding. Last check: 2007-10-22)
		The Sierpinski curve is a base motif fractal where the base is a square.
		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.
		The curve is a two-dimensional generalization of the Cantor set.

	Sierpinski Curve (Site not responding. Last check: 2007-10-22)
		While the Hilbert curve is an open curve, the Sierpinski curve is closed; it bounds an area that is 5/12 that of the square it fills.
		The Sierpinski curve consists of four open curves linked together by line segments located in the outer corners.
		Like the Hilbert curve, the Sierpinski curve is also the limit of an infinite series of curves.

	Sierpinski Carpet
		The Sierpinski carpet is the intersection of all the sets in this sequence, that is, the set of points that remain after this construction is repeated infintely often.
		Sierpinski used the carpet to catalogue all compact one-dimensional objects in the plane (from a topological point of view).
		So the Sierpinski carpet was actually invented by Stefan Mazurkiewicz, who in 1913 wrote his Ph.D. thesis under the supervision of Sierpinski on curves filling a square.

	Sierpinski Gasket
		The Sierpinski gasket, also known as the Sierpinski triangle, is the intersection of all the sets in this sequence, that is, the set of points that remain after this construction is repeated infinitely often.
		The Sierpinski gasket is also referred to as the Sierpinski triangle or as the Sierpinski triangle curve.
		It apparently was Mandelbrot who first gave it the name "Sierpinski's gasket." Sierpinski described the construction to give an example of "a curve simultaneously Cantorian and Jordanian, of which every point is a point of ramification." Basically, this means that it is a curve that crosses itself at every point.

	Recent Papers of Robert L. Devaney
		These halos are Sierpinski holes in which the corresponding maps have Julia sets that are Sierpinski curves.
		These Sierpinski curves have complementary domains that consist not only of the basin of attraction of infinity, but also of the basins of other finite attracting cycles.
		These Julia sets are generalized Sierpinski gaskets and are produced when the critical orbits for these maps land on repelling periodic points in the basin of infinity.

		A famous spacefilling curve is that due to Sierpinski, which is formed by repeatedly copying and shrinking a simple pattern (the convoluted tour in Figure 1).
		A useful property of a spacefilling curve is that it tends to visit all the points in a region once it has entered that region.
		To accompany this is a table of Sierpinski indices of the points of a 100 x 100 grid [pdf format, 22 pages], with which you can set up your own routing system in an afternoon.

		The curve on the left was drawn with the geometric method.
		Intuitively, the length of the Sierpinski gasket is the total of the length of all the segments required to draw the object.

		Since the sierpinski gasket is fractal, such a function could only (as far as I know) be defined as a limit.
		It is evident that f is defined on the interval <0, 1> and that the image of f is the sierpinski gasket.
		Handily, your definition of the sierpinski gasket in terms of areal co-ordinates makes it clear from the rules of the game that f(x) is always an element of the sierpinski gasket.

		The Sierpinski curve: a lesson in debugging and conversion.
		Sometime in the 1700's, mathematicians described the word "curve" more precisely than had been done previously by defining a curve as the loci of points that satisfy equations that are continuous functions.
		Peano's curve is a legitimate diagram of a continuous function, yet nowhere on it can a unique tangent be drawn because at no instant can one specify the direction in which the point is moving.

		Even in the bleak lanscape of a frozen tundra, patterns can be found at all scales, whether in the gentle curve of a wind swept serac or in the intricate crystalline structure of a snowflake.
		In fact, this sequence of drawings does have a limit, in a technical sense, and that limit is called "von Koch's Curve." What's interesting, is that if you arrange 3 copies of the curve along the edges of an equilateral triangle, you get the figure at left.
		The limit of this sequence is called Sierpinski's Gasket, named for Waclaw Sierpinski (1882-1969), a polish mathematician who made great contributions to the foundations of mathematics.

		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.
		As early as 1915, Sierpinski described a "gasket" or a "triangle" with repeated and proportionally reduced areas.
		Today these shapes are widely known as "fractals." Sierpinski's triangles would later emerge to be among the most recognizable shapes or patterns in all computer graphics.
