two-dimensional lattices

A two-dimensional lattice is a regular, grid-like arrangement of points or objects in a flat plane, where each point has a consistent pattern of neighbors around it. Imagine an infinite sheet covered with evenly spaced dots, where the dots align in rows and columns, creating a repetitive pattern. This structure helps scientists understand the arrangement of atoms in crystalline materials, analyze patterns in nature and art, or design algorithms in computer graphics. Essentially, it's a way to describe organized, repeating patterns in two dimensions that exhibit symmetry and uniformity.
