Abstract: Continued fractions are at the heart of one of the oldest mathematical
discoveries - the Euclidean algorithm for finding the greatest common
divisor of two numbers. Over the millenia, this mathematical gem has
revealed ever increasing numbers of beautiful facets, and can even be
found in a modern pinnacle of mathematical achievement - the Ending
Lamination Conjecture. We will discuss some of the highlights of this
story, which touches on Fibonacci, Gauss, and Hyperbolic Origami.
