M229: The mysteries of PI in Splash Spring 2015 (Apr. 18, 2015)
Come and learn all about PI. How to approximate it, from the simplest methods to the most elaborate ones. And what are its applications? (aka. radians) And there will be pie (maybe).

M195: The mysteries of PI in Splash Splash Fall 2014 (Nov. 15, 2014)
Come and learn all about PI. How to approximate it, from the simplest methods to the most elaborate ones. And what are its applications? (aka. radians) And there will be pie (maybe).

M154: Prime Numbers, the rockstars of math in Splash Spring 14 (Apr. 05, 2014)
There are a lot of rumors going around prime numbers: unlimited, impossible to find, used for encryption, etc. We'll try to explore their properties in a clear but accurate way.

M117: Complex Numbers in Splash Fall 2013 (Nov. 16, 2013)
A first introduction to complex numbers, what they are, why they are used, and what is their application. And our superstar: $$i=\sqrt(-1)$$

M63: Prime Numbers, the rockstars of math in Splash Spring 2013 (Mar. 30, 2013)
There are a lot of rumors going around prime numbers: unlimited, impossible to find, used for encryption, etc. We'll try to explore their properties in a clear but accurate way.

M2: Solving Linear Diophantine Equations (and still being cool) in Splash Fall 2012 (Oct. 14, 2012)
The goal is to learn how to solve over the integer domain simple diophantine equations, of the form ax + by = c (where a b c are fixed integer). For that, "students" will discover the gcd, the divisibility definition, Euclid's (Gauss) Lemma, and the mathematical logic. Some simple proofs will be done, depending on the class' speed.
