## October 26, 2013 – Austin Marstaller – “Cantor Sets”

Posted in meeting, tagged AMC 8, Austin Marstaller, Cantor set on October 24, 2013| Leave a Comment »

**This week’s math circle presenter will be MMC participant and UTD student, Austin Marstaller. He’ll be discussing Cantor Sets, a set of points lying on a single line segment that have a number of interesting properties. Learning about Cantor sets is a great way to introduce general topology.**

## Dr. Branislav Kisačanin – Geometry of Triangles

Posted in math circle, meeting, tagged Branislav Kisacanin, cevians, Euler Line, excircle, Fermat Point, Stewart's Theorem on April 16, 2013| Leave a Comment »

This Saturday, April 20th Dr. Kisačanin will return for another of his fantastic lectures. Triangles factor into almost every math contest in addition to being endlessly fascinating objects in themselves. Here is Dr. Kisačanin’s description of the session with links to resources:

In this talk about geometry of triangles we will see two different proofs of Stewart’s theorem, derive formulas for important cevians, and solve several interesting geometric problems.

We will also look at other important points in triangles (Fermat point, centers of excircles, …) and look at the Euler line, the nine-point circle, and related problems.
