**Trees** are one of the most important data structures in computer science, forming the foundation for databases, file systems, and search algorithms. In this 90-minute class, we’ll explore the basics of tree data structures, how they’re organized, and why they’re so powerful for managing hierarchical data.

We’ll cover key concepts like nodes, edges, root, leaves, and depth, then move into practical examples in Python. You’ll learn how to build a tree, traverse it using common algorithms like depth-first search (DFS) and breadth-first search (BFS), and see how trees are used in real-world systems, from folder structures to decision-making processes.

Perfect for beginners who know some basic Python, this class will give you the tools to understand and implement trees in algorithms and data structures. By the end, you’ll not only know how trees work but also why they’re essential to solving complex computing problems efficiently.

The Algorithms and Data Structures Series: Trees 101

Online event

Join us for an epic adventure through one of the greatest works of world literature, **Homer’s Odyssey, Book 9**.

In this class, we’ll dive deep into the ancient world and explore the texts of this world classic to uncover what it meant for the Greeks.

You’ll follow the heroic journey of Odysseus as he faces mythical creatures, gods, and challenges on his quest to return home. Together, we’ll analyze key passages to explore themes of courage, loyalty, and perseverance, and discuss how Greek mythology and culture shaped this epic poem.

Along the way, we’ll also examine how *The Odyssey* still influences modern storytelling today.

This class is perfect for anyone interested in world literature, mythology, or ancient history, and for readers who love adventure on the page. Whether you're a seasoned reader or new to the classics, you’ll experience the excitement, mystery, and significance of ancient Greece.
