At TED2010, mathematics legend Benoit Mandelbrot develops a theme he first discussed at TED in 1984  the extreme complexity of roughness and the way that fractal math can find order within patterns that seem unknowably complicated.

In geometry, the Peano curve is the first example of a spacefilling curve to be discovered, by Giuseppe Peano in 1890. Peano's curve is dense in the unit square, and was used by Peano to construct a continuous function from the unit interval to the unit square, motivated by an earlier result of Georg Cantor that these two sets have the same cardinality. Because of this example, some authors use the phrase "Peano curve" to refer more generally to any spacefilling curve.To learn how big infinity really is, and more about George Cantor, check this out.In topology and related branches of mathematics, a Hausdorff space, separated space or T_{2} space is a topological space in which distinct points have disjoint neighborhoods. Of the many separation axioms that can be imposed on a topological space, the "Hausdorff condition" (T_{2}) is the most frequently used and discussed. It implies the uniqueness of limits of sequences, nets, and filters. Hausdorff spaces are named after Felix Hausdorff, one of the founders of topology. Hausdorff's original definition of a topological space (in 1914) included the Hausdorff condition as an axiom.
