In this lecture we describe several folk theorems concerning
the Mandelbrot set. While this set is extremely complicated
from a geometric point of view, we will show that, as long as
you know how to add and how to count, you can understand this
geometry completely. We will encounter many famous mathematical
objects in the Mandelbrot set, like the Farey tree and the
Fibonacci sequence. And we will find many soon-to-be-famous
objects as well, like the "Devaney" sequence. There might
even be a joke or two in the talk.
