💎Crystallography

What do you learn in Crystallography

Crystallography explores the arrangement of atoms in crystalline solids. You'll study crystal structures, symmetry operations, and diffraction techniques like X-ray and neutron scattering. The course covers crystal systems, Bravais lattices, and Miller indices. You'll also learn about crystal growth, defects, and how structure relates to material properties.

Is Crystallography hard?

Crystallography can be challenging due to its mix of chemistry, physics, and math. The 3D visualization of crystal structures can be tricky at first. But once you get the hang of symmetry operations and diffraction patterns, it becomes more manageable. The math isn't too intense, but you'll need to be comfortable with geometry and some linear algebra.
