**Alejandro Bravo Doddoli, UCSC****Fun Math, Why Can the Child Swing Alone?**

As a young man Galileo noticed that a pendulum swings at a constant rate (at least, almost constant for small angles), since this moment the study of the pendulum became an important topic of the Mechanics. We will make a review about the history of the pendulum to finish studying the problem of a child playing in the swing. We will propose a model in order to write down the equation of motion, then we will make a qualitative study and comparison with the nature.
