“A presentation is not a set of slides: it is all about someone having something to say to an audience-slides or no slides.” With this aphorism of Doumont in mind, we will learn how to use the Beamer package in the typesetting software LaTeX to create effective slides for short talks. Beamer is a powerful tool that inherently forces you to carefully consider how to use judiciously use slide space, enabling the creation of useful slides that complement your talk. This workshop is designed for those with a basic understanding of LaTeX, including those who attended Fall 2025’s Introduction to LaTeX. We will go through some examples of efficient slides, walk through how to use Beamer, and finish by creating our own mini-slide deck as a workshop activity.
