Sigmoid Curve as Area Accumulation of Standard Normal Distribution

Here we investigate the area accumulation function of the standard normal curve (also called the bell curve). The resulting function is a scaled shift of the error function, erf(x).

$Hilbert Curve from an L System In this video, we describe two how to draw a plane filling curve called the Hilbert curve using an L-system. While the substitution strings are a bit complicated, the rules for this system are easy to implement and use to draw a level 8 Hilbert curve (to dramatic music).

$Summing Powers of 1/6 via a Square Dissection This is a short, animated visual proof demonstrating the infinite sum of the powers of 1/6 using a square. The result is somewhat surprising given that it doesnt seem obvious how to decompose a square into powers of 1/6 and how the resulting area could easily be seen as 1/5 of a square.
