## What do you learn in Mathematical Crystallography

Mathematical Crystallography explores the symmetry and structure of crystals using mathematical tools. You'll dive into group theory, linear algebra, and geometry to describe crystal lattices and symmetry operations. The course covers topics like point groups, space groups, and Bravais lattices, teaching you how to analyze and predict crystal structures mathematically.

## Is Mathematical Crystallography hard?

It can be pretty challenging, not gonna lie. The math gets pretty abstract, and you'll need a solid grasp of linear algebra and group theory. But if you're into puzzles and spatial reasoning, you might actually find it kinda fun. The toughest part is usually visualizing 3D structures and symmetry operations in your head. Once you get the hang of that, things start to click.
