January 9, 2016 – **Jacob Cordeiro** – “LaTex and Group Theory”

This talk will be split into two parts: LaTeX and Group Theory. In the first half of the math circle, Jacob will provide a brief introduction to LaTeX. LaTeX is a very useful program for writing up academic proofs and papers, and you can use it to make your work easier in all sorts of classes and projects. In the second half, we’ll explore the basics of “group theory,” a form of abstract algebra with some surprising applications.

January 23, 2016 – **Austin Marstaller** – “Graph Theory”

A graph consists of some points called vertices connected together by some lines called edges. Many interesting questions arise in graph coloring problems in which the edges and/or vertices are colored following some restrictions. In this talk, I will introduce graph theory and explore some interesting graph coloring problems such as representing Sudoku as a colored graph.

February 4, 2016 – **Dr. Arthur Benjamin** – “Secrets of Mental Math”

Imagine being able to accomplish calculations faster than a calculator! Dr. Art Benjamin has unlocked the Secrets of Mental Math and performs complex calculations in his head with ease. He will perform and explain how to mentally add and multiply numbers, how to figure out the day of the week of any day in history, and other amazing feats of mind.

April 16, 2016 – **Austin Marstaller** – “Hexaflexagons”

A hexaflexagon (also called a kaleidocycle) is a folded geometric figure that can be “flexed” to expose many sides. We will examine Flexagons in general and explore in detail several of its variations. In particular, we will create our own paper hexaflexagons and explore the combinatorial properties that it has.

September 10, 2016 – **MTip Phaovibul** – “Geometric Probability”

If a stick is broken at two random points, what is the probability it will form a triangle? This question, called the broken stick problem, first appeared about 150 years ago in an examination at Cambridge University. It attracted the interest of 19th century French probabilists, and more recently was popularized by Martin Gardner. Learn about this classic problem and its applications in mathematics.

October 1, 2016 – **Dr. Po-Shen Loh** – “Math and Creativity”

**Do you enjoy interesting problems? Do you want to find out how to make the most of math competitions?**

Professor Po-Shen Loh will address puzzles that don’t look mathematical, but ultimately are unlocked by mathematical insights. Come join us for this very special math circle on Saturday evening. This talk is for curious learners of all ages.
